YKアキュラシ― Product Lineup

As high performance continues to evolve, electronic components are becoming increasingly complex, with structures such as single-sided, double-sided, and multilayer designs, some of which have dozens of layers and high-performance durability. Materials like resin, metal, and fiber are also complex composites, and even though they require simple cutting, achieving stress-free cutting without damaging the workpiece is best accomplished with water jet cutting, which is also a frequently requested item.

• Printed Circuit Board

It is Ti6Al4V 64 titanium, which is lightweight, strong, and resistant to rust. From the initial stage, we minimize the occurrence of distortion as much as possible so that it does not significantly affect later processes and precision. Simple primary processing cutting from the raw material before product manufacturing is done. Due to water jet cutting, the occurrence of warping or distortion is almost nonexistent, limited to certain materials, thicknesses, and processing shapes. The cause of warping is due to the stress in the material, and it does not produce significant distortion or twisting camber as seen with other processing methods.

• alloy

Using no cement or water, we created a concrete that firmly binds crushed stone, sand, and calcium carbonate with thermosetting resin as the binder. This concrete is resistant to chemicals, wear, and has high strength, making it difficult to visually inspect the cross-section with standard cutting machines, which is why we received your request. The resin concrete lid was processed using water jet cutting. Although it appears flat, it has a drop lid shape, so the surface features a gentle curve and taper, and there is a recess for the handle on the underside, requiring some ingenuity in the setup.

Request for cutting special resin with high dielectric breakdown voltage In quantities that do not reach mass production with molds Prototype comparison with machining While the processing accuracy does not reach the level of machining, we have received numerous requests for shape prototypes, etc.

• Plastic utensils and containers
• Plastic bearings

Accurately measuring whether the performance meets the design specifications, and further cutting for visual inspection of the cross-section while maintaining the structure of conductors, cores, insulators, etc., is the area in which water jet cutting excels the most. Depending on the size and shape, we consider the cutting direction and fixation to minimize damage during cutting, ensuring that even complex structures made of composite materials experience minimal deformation and result in a smooth cross-section.

• Inductor Coil
• Other electronic parts

Interior function introduction cut model Instead of the popular dial-type BOA, it uses a shoelace type. The laces were removed in advance, and issues such as handling the internal cavity, unstable tongue, and lightweight measures were addressed with the same countermeasures as other shoe cuts. The thickness of the foam material in the midsole showed slight irregularities, but otherwise, it was cut almost vertically, with the cutting width kept within approximately 1mm.

• Safety shoes and sneakers

In the cutting process of aerodynamic parts for the Student Formula Japan competition vehicles, we achieved high-precision cutting that completely eliminates thermal effects. The Doshisha University Formula Project (DUFP) required a balance between lightweight design and high rigidity for the aerodynamic parts.

• aluminum

For the verification of the internal structure of a commonly used full-bore design in fluid control and the piping joints, water jet cutting is optimal for accurately verifying the structure of a ball valve, which has a smooth cutting surface compared to other cutting methods and operates by opening and closing through the rotation of the valve body, without any impact or thermal deformation. The lever handle was pre-removed for setting, the valve housing was made of forged brass, the ball was nickel-chromium plated, the seat material was fluororesin, and the O-rings were made of fluororubber. Despite the various materials and void structures, we were able to perform the cutting without significant damage, including to the movable parts.

• Valves and fittings
• valve

A special product for tightening work that requires insulation to prevent electrical conduction between the tool and the bit. It was composed of chrome vanadium steel and a coating part made of a special resin composite. To prevent part loss after cutting, an L-shaped cut was made, and a method was used to minimize disturbances on the cutting surface caused by jet water flow diffusion in the hollow section, resulting in a smooth and easily verifiable cross-section.

• socket
• Other metal materials

It is a smart audio device that fits in the palm of your hand, producing sound that spreads in all directions and can be operated through dialogue. In response to a request for internal structure verification, we proposed a 120-degree opening cut instead of equal divisions to avoid missing internal components due to cutting, while also considering the protection and fixation of the outer mesh material of the very clean, seamless casing.

• others

The structure was made of aluminum, titanium, and carbon fiber. At your request for an internal structure verification, I cut it in half from the sole to the crown side. However, I am more interested in the assembly order, adhesive application, and final filling rather than the structure itself. Since it has a high void ratio, the work requires careful attention to stability and internal diffusion. In the end, it seems that a gel for sound dampening and balance adjustment is injected from the hosel.

Enamel is a product that involves fusing a glass-like glaze onto the surface of metal materials such as iron and aluminum at high temperatures. By the way, enamelware is also referred to as cloisonné or cloisonné enamel in the context of crafts. It can be used directly and is heat-resistant, and due to its high thermal conductivity, it is excellent as a cooking utensil. Since it is covered with glass, it does not rust and has excellent cooling properties. Additionally, it is said to be resistant to retaining odors. Cast iron enamel pots are made using a special manufacturing method that increases the contact area between the metal and the glaze, allowing for precise measurement of whether the performance meets the design specifications. Furthermore, cutting was performed for visual verification of the cross-section. The special material, which consists mainly of metal and silica (silicon dioxide) with a glass-like glaze fused at high temperatures, is particularly well-suited for water jet cutting. Including curved sections, it was possible to conduct precise verification without any cracks, chips, or delamination.

• Composite Materials

Heater-integrated nozzle components for supplying resin in a molten state to injection molding molds for thermoplastic plastics. Internal inspection of hot runner nozzles to verify whether there are any areas of resin retention on the flow path sides or internal structures. This is an example that utilizes the advantages of water jet cutting, which can cut composite materials such as special alloys and resins without stress.

• nozzle

It is said that the innovative joining technology of non-mixed FSW (Friction Stir Welding) achieves high strength without deformation, cracking, or distortion, overcoming the issues of conventional fusion welding as well as previous FSW problems. The copper-aluminum joining plate is cut using water jet cutting, allowing for stress-free cutting of dissimilar materials simultaneously. This time, the shape is simple, but it seems that we will continue to receive test piece cutting for prototypes and fracture tests before mass production.

• Composite Materials
• Non-ferrous metals
• aluminum

It is a material that excels at high temperatures, but due to rapid temperature changes and environmental changes such as impacts, we request cutting it to a size that can be attached to testing equipment for various tests for its intended use. It seems that a versatile material has been developed that maintains strength and toughness even at high temperatures and has high thermal conductivity, but its machinability for mechanical cutting is strict, and we are currently considering processing it with water jet even for mass production.

• Ceramics

Thickness 80mm, outer diameter φ750mm gear cutting Base material weight 127kg, even after lightweight inner diameter cut Chain block is essential Aluminum thick plate gear shape water jet cutting With dynamic water jet, the cutting head is automatically tilted to minimize taper, reducing cuts and taper caused by water flow delay, resulting in high-precision cutting.

Verification cutting of resin filling agents for special flow meters Water jet cutting of flow meters This is a device with a three-dimensional structure that integrates electrical circuits and fine mechanical structures on a semiconductor substrate. For the purpose of verifying the waterproof resin filling condition in the void areas, prototypes with several types of filling resins were cut. Since it is a structure with significant hardness differences between resin, metal, etc., complete vertical cutting is difficult, and there are some areas that may be gouged. However, the verification itself was carried out without any issues.

• Flow Meter

The torii gate at the shrine is adorned with a plaque that typically displays the name of the shrine and the deity enshrined there. This plaque, known as the torii kami-gaku, is usually made of wood and features intricate carvings or assembly work. It is also referred to as torii-gaku or hen-gaku. In recent years, many have been remade in metal (aluminum) while maintaining the traditional design and ensuring strong support. Our company has also undertaken part of this production. The torii kami-gaku is cut using water jet technology. The famous cherry blossom spot, "Hirano Shrine" in Kyoto, features a torii kami-gaku cut from A5052 aluminum with the characters "Hirano Kōtaijin" measuring 15mm x 550mm x 1810mm. The surrounding frame measures 10mm x 1085mm x 2215mm. After the water jet cutting, the gold-colored parts of the surface are finished not with paint but with gold leaf at the request of the client, and the receiving brackets are also beautifully finished with excellent craftsmanship.

Steelmaking pig iron extracted by reducing iron ore in blast furnaces and electric furnaces, 50mm × 105mm × 300mm. Request for rough processing of research test pieces. Pig iron ingot - water jet cutting. Primary processing sliced to about 5mm width. The cutting was performed at ultra-low speed with high strength and toughness.

• Steel

Request for extraction cutting of necessary components for verification and research, without affecting the entire large PCB board of the control device as much as possible. Water jet extraction cutting of the substrate integrated circuit. The board was quite large at 300mm x 300mm, and there were three extraction parts. Since it was water jet cutting, immersion could not be avoided, but we took protective measures to minimize the impact on areas other than the necessary ones, and the extraction was successfully completed.

Solving conventional issues and achieving high-precision verification Challenges in verifying the fastening state of polypropylene resin bottle caps Polypropylene resin, known for its lightweight, durability, and recyclability, is widely used in various applications, including bottle caps. However, traditional cutting methods for verification purposes have the following challenges: Deformation and damage due to heat generation: High temperatures can deform the material, potentially hindering the verification of the fastening state. Accuracy degradation due to wear: The cutting surface may wear down, making it difficult to accurately assess the original condition. Verification impossible due to damage: If damage occurs during the cutting process, verification itself becomes impossible. Contamination of the fastening cross-section: If the cutting surface becomes dirty, it may hinder the verification process. In this case, due to the large hollow part of the polypropylene resin bottle cap cutting material, we implemented measures to suppress the scattering of the jet water flow while cutting. Although the generation of burrs could not be avoided due to the low hardness of the resin, the joint parts remained intact, resulting in verification results that satisfied our customers.

Utilize rising copper plates efficiently! Achieve high-precision hole drilling and slitting with water jet cutting. Challenge: Avoiding peripheral cutting due to rising copper material costs. In recent years, the price of copper materials has surged significantly, making the reduction of manufacturing costs an urgent issue. Traditional processing methods involve cutting out the entire copper plate and then shaping it, resulting in substantial material loss. Solution: Achieve processing that minimizes material loss with water jet cutting. Therefore, we propose a method called water jet cutting with arbitrary position designation. Water jet cutting operates by spraying a high-pressure water stream from a nozzle, allowing for cutting with a narrow kerf to eliminate unnecessary parts, thus minimizing material loss and removing only specific areas without peripheral cutting. Compared to conventional cutting methods, water jet cutting has less thermal impact, preventing deformation and burning of the copper plate. YK Accuracy Water Jet Cutter processing offers high-quality processing services tailored to customer needs, backed by extensive experience and advanced technology.

Request for internal inspection of the winding of the stator coil. In conventional sawing, issues such as heat generation, wear and damage, and contamination of the cross-section are problematic. To ensure minimal damage and a uniform cross-section, water jet cutting was chosen. Due to the reduced thermal impact, damage to the winding and insulation material is minimized. The protrusions on the frame were removed in advance, and cutting was performed with minimal friction and impact to suppress damage. However, as the material substrate becomes exposed due to cutting, there is a certain processing time involved, which can lead to the formation of an oxide film, and rust may occur on some metal parts.

Currently attracting significant attention, the interior and exterior wall material "SOLIDO" from major exterior material manufacturer Keimyuu Co., Ltd. is a sustainable material that utilizes the texture of cement and consists of approximately 60% recycled materials. This time, we conducted test processing for a project that involved creating an accent wall in part of the interior by cutting out a logo and stripes. The raw material feel, reminiscent of exposed concrete, is appealing, so it is important not to stress the surface or the material itself since it is not painted. There are absolutely no issues such as cracking, chipping, or delamination during initial penetration, and it does not generate stress in the material itself, allowing for precise cutting even with intricate designs.

Request for internal verification of the interface junction block Similar to coil-related issues, we have chosen water jet cutting to ensure minimal damage and a uniform cross-sectional state, addressing problems such as heat generation, wear and tear, breakage, and contamination during conventional sawing. Due to the minimal thermal impact, we were able to cut materials including resin, copper wire, insulation materials, and connectors while minimizing damage. In addition to simple division cutting, we can perform partial opening cuts at angles such as 90 degrees and 120 degrees, preventing damage, slipping, and loss of internal components. Advantages of Water Jet Cutting Wide range of materials: Capable of cutting various materials such as metals, resins, rubber, and ceramics. Complex shape cutting: Able to cut complex shapes, including curves and holes. Non-contact processing: Processes without direct contact with the workpiece, preventing damage to the material.

This is for verifying the bonding state of tungsten electrodes and copper nozzles. They are made of a high-temperature, high-speed, and wear-resistant alloy material, but simultaneous cutting of dissimilar metals can be handled without any issues using a water jet cutter. In recent years, it seems that some inner walls are made of fine ceramics, and unfortunately, cutting fine ceramics with our water jet cutter presents very strict conditions.

In recent years, mainstream thick-soled running shoes with carbon plates have emerged. These high-quality super running shoes feature materials with distinct characteristics for rebound and cushioning in the inner part, along with a carbon fiber plate that enhances propulsion. This request is for a cross-sectional structure verification and introduction, so it was essential to minimize dirt and roughness during the water jet cutting process. The shoelaces were removed in advance, and measures were taken to address the internal cavity and unstable tongue. There was a slight disruption in the area beyond the carbon plate in the midsole, but otherwise, the cutting was almost vertical, with a cutting width contained within approximately 1mm.

Request for cutting to measure and verify the lining thickness of short elbow piping with rubber lining on the inside. Initially, flanges were welded on both ends, but they were removed beforehand due to being an obstacle during cutting. Water jet cutting of the rubber-lined elbow: Although water jet cutting does not cause thermal effects, it is a so-called back-opening type cut. Measures were taken to minimize damage to the internal rubber lining by controlling the jet dispersion from the hollow part of the water jet cutter, ensuring a clean cut without material alteration.

• Rubber

Internal verification cutting of tires for riding rice transplanters in agricultural machinery. This is a composite material simultaneous cutting aimed at verifying the bonding and fitting conditions between the rubber and metal parts. Although it is a water jet cutting process with no thermal effects, deformation occurred due to residual stress in the metal parts, causing the entire wheel to deform to the extent that it could not be separated along the specified cut line in a single pass, even with four spokes present. Therefore, multiple cutting operations were performed to achieve separation. There was some internal damage due to jet scattering in the hollow parts, but the impact was minimal because the hollow was of small diameter. The water jet cutter, which has no thermal effects, cut the material in a clean state without altering its properties, allowing for visual inspection of areas with very slight thickness changes.

• Rubber

Training swim timing measurement device "Swim Touch" It reduces the burden of stopwatch measurement by coaches, allowing individuals to measure their times personally and engage in image training while realistically viewing their times. It is a groundbreaking timing machine. The easy-to-install fixed cushioning material does not require construction and is made by cutting EPT solid rubber. Since the shape changes depending on the installation pool, it is difficult to use molds, so we accept requests for water jet cutting that can accommodate small quantities as needed.

• Rubber

For each new design, we provide support for new layout designs of power electronics components. We cut efficiently from supplied materials with high nesting to minimize waste. We also respond quickly to custom orders with different shapes, sizes, and quantities each time.

• Non-ferrous metals

Verification of wear damage on the rotating shaft of home appliances, divided into two sections. This time, we particularly focused on the verification of dissimilar metals and resin parts. After cutting, there were no small floating components like bearings, so we carefully paid attention to the distance from the object during water jet cutting. It seems that the verification was carried out without any issues.

• plastic

When voltage is applied, organic materials emit light, allowing for a product that can create vivid and detailed images with a wide viewing angle in a thin design without a backlight. While we excel at cutting other complex laminated structures, we struggle with water jet cutting due to the use of glass in the sealing material and substrate, making it difficult to achieve completely damage-free cutting and limiting the specifications for sample extraction. However, both electrodes, the organic layer, resin film, aluminum panels, and control boards were tested with minimal damage.

Connector for solar power generation panel components Considering durability against waterproofing and aging, the shape is robust, but as an internal verification after molding, this request comes from our coil cutting case. This is a task we excel at, maintaining the structure of each copper wire and insulator, using water jet cutting. Since it is bonded to the solar power generation panel, there were slight cracks in the reinforced glass section, but the intricate internal components experienced no damage during cutting, and the complex structure was cut with minimal deformation, resulting in a smooth cross-section.

• Other Connectors

Extraction of test samples from arbitrary positions of glass top material for built-in stoves, which is resistant to high temperatures, shocks, and dirt. Due to differences in partial painting, back structure, and treatment, samples are cut using both punching and cutting methods. The material is highly resistant to thermal shock and impact, with a long lifespan of 15 to 20 years. Although water jet cutting allows for the creation of square holes, circular cutouts, and arbitrary curved shapes at any position, our abrasive has a coarse particle size, which can cause minor chipping, but no significant cracks or chips have occurred.

• Glass

Independently molded resin balls New hemispherical applications have emerged However, since the quantity is not sufficient for molding, we request verification of feasibility through cutting instead of mold production. With diameters of φ10mm and φ20mm, they are small and lightweight, and while there are challenges such as setting, there is no issue with the cutting itself, and we have conducted test cuts.

• Plastic bearings

It seems that each manufacturer has its own characteristics regarding drill chucks that can secure cutting tools without using a chuck handle (chuck key). While you expressed a desire for complete equal division, I considered that after cutting, parts other than the body might come loose or fall, making it difficult to maintain the condition. Therefore, I proposed cutting at an offset from the central rotation point. Although it is somewhat difficult to diagnose, there is little disturbance on the surfaces of the hollow and gap areas, and various materials such as iron, alloy steel, chromium-molybdenum-vanadium steel, carbon steel, TPE, PA, PP, etc., were cut into cross-sections that are easy to verify without separating the spindle and guide.

Recycling of used solar panels expected in the future is a difficult issue that requires the development of technology to disassemble and separate materials for resource recovery. The reinforced cover glass that protects the modules connected to the cells is the most problematic part in water jet cutting. When an initial impact is applied, the entire glass shatters and breaks. The advantage of water jet cutting is that it exerts almost no stress on the material, but even when the jet cuts from the outside of the workpiece, slight initial impacts can cause cracks due to the imbalance of compressive and tensile stresses. However, due to the recent improvements in the reinforced cover glass itself and the effects of the laminated film sheet, instances of the entire glass breaking have become almost nonexistent. This time, we received a request to downsize a panel that has already shattered for separate verification and research.

• Processing Contract

The firing process is diversifying to meet various needs. We can accommodate custom specifications for electric furnaces beyond standard sizes. Plates with an alumina (Al2O3) purity of 99.5% or higher are industrial materials with excellent heat resistance, hardness, and electrical insulation properties. Due to their hardness and brittleness, a different approach is required compared to general metal materials, which may involve using diamond saws or special electrodes for wire electrical discharge machining. However, considering factors such as thermal impact, cost, delivery time, and processing accuracy, water jet cutting was chosen. First, we conducted a test cut just to be safe; although a tapered cross-section was produced, we determined that cutting was feasible and formally accepted the order.

This unique building material, with its distinctive shape and surface color, creates a unique atmosphere visually. It has been adopted for the interior of a store, and we have undertaken some processing. It is said to provide an impressive ambiance for visitors and has received positive feedback. Among metal materials, it is a durable and rust-resistant material with various cutting methods available. The material used this time consists of corrugated sheets with a height difference of about 10mm at a 30mm pitch. While simple cutting poses no issues, the processing required is for arbitrary positions unrelated to the peaks and valleys, which caused difficulties for the processing contractor. Therefore, our water jet cutting was chosen. However, since the cutting exposes the raw surface completely, we carried out drying and curing after each of the multiple corner cutouts.

• Other metal materials

Hafnium metal, widely used in control rods for nuclear reactors, jet engine components, semiconductor materials, etc. This time, we are cutting small pieces for additive materials in the production of special alloys. Due to its high hardness, tendency to oxidize, and uneven thickness, water jet cutting was chosen. There were various issues with small piece cutting on our equipment, making continuous processing difficult. However, with some leeway in the allowable tolerances, we devised a setting and cutting method to perform continuous cutting of 10mm squares. There were no issues such as abrasive particle embedding on the cutting surface, and after testing and verification of the cutting, we received a formal order.

• Other metal materials

Very lightweight all-weather mid-cut boots. This project aimed to verify the laminated fixation state of the outsole, midsole, insole, and cushioning materials. Therefore, instead of cutting from the usual upper side, we proposed and executed the cut from the sole side. Given the lightweight and unstable condition, we stabilized it with a unique setup, allowing for a clean cut without significantly disturbing the water flow, thus meeting the user's request.

• Other polymer materials

Excellent corrosion resistance and lightweight pure titanium material. Since there are no ready-made bars of 3mm x 3mm, we requested cutting from sheet material. Other processing machines caused significant distortion due to thermal effects. There were many issues with yield as well. We considered water jet cutting and conducted an initial test cut. We performed cutting to avoid the generation of residual stress and cut flat bars. It was evaluated that we improved quality and yield compared to conventional processing machines.
