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, cutting itself poses no issues, and we have conducted test cuts.

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 detach or fall, making it difficult to maintain the condition. Therefore, I proposed cutting at an offset from the central rotation point. Although the state is somewhat difficult to diagnose, there is little disturbance on the surfaces of the cavities and gaps, and various materials such as iron, alloy steel, chrome-molybdenum-vanadium steel, carbon steel, TPE, PA, and PP were cut into easily verifiable cross-sections without separating the spindle or guides.

Request for downsizing cutting of the test specimen from the formed body that has been cast. Other cutting machines may introduce new stress to the test specimen due to vibrations during cutting, making it unsuitable as a test piece. With water jet cutting, we received the request because it can cut into arbitrary shapes without stress, allowing the specimen to remain viable. Care was taken with the cutting speed to ensure that there was no impact on the rebar, which is subject to severe corrosion, or on the delamination and voids between the concrete layers.

The firing process is diversifying to meet various needs. We 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 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 officially 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 service was chosen. However, the cutting exposes the raw surface completely, so after processing multiple corner cutouts, we carried out drying and curing each time.

Hafnium metal, widely used in control rods for nuclear reactors, jet engine parts, semiconductor materials, etc. This time, we are cutting small pieces for additive materials in the production of special alloys. Due to its high hardness, susceptibility to oxidation, and uneven thickness, water jet cutting was chosen. There are various issues with small piece cutting using our equipment, making continuous processing difficult. However, with some leeway in 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. YK Accuracy Co., Ltd.

A5052 20mm Sprocket Image Cut Sample The machining of the gear's slit section has a width of 1.3mm and is done in a single continuous motion. In general machining, it is thought that the spacing of the slit section may become uneven due to thermal effects, but it has been completed in a perfectly uniform state. The abrasive water jet is the optimal machining method for applications with high added value and is widely used for cutting aluminum and steel materials. It can cut materials ranging from 0.3mm to 180mm in thickness, regardless of the manufacturing volume. Since it does not undergo mechanical stress and is not affected by thermal deformation or thermal effects, it provides high-quality cut surfaces without stress, making it ideal for the production of test specimens made of metals and resins. Additionally, it saves time and costs that would traditionally be spent on secondary processing, and the setup and jig configuration can be completed in just a few minutes, thereby enhancing productivity. Water jet cutting is an efficient and optimal method for precision rough machining.

Ultra-high molecular weight polyethylene (UHMWPE) new light board 40mm Segmented arc shape cutting processing Multiple arbitrary arc shapes are laid out in numerous segments to efficiently utilize materials, minimizing waste and significantly reducing material costs. We always consider profit assurance and yield improvement, keeping the spacing to a minimum for nesting. In the water jet cutting of thick resin boards, there are two specific issues: water flow delay and taper. However, with Flow's dynamic water jet, high-speed and high-precision taper-free cutting is possible, eliminating heat generation during processing and preventing chips from softening or thermally deforming. The 40mm thick board is processed almost vertically, cutting four types of segmented arcs and fan shapes into about 20 parts from a 1000mm x 2000mm board, reducing the conventional machining waste rate from about 50% to below 10%.

Carbon fiber reinforced resin board impregnated with thermosetting resin. With high strength and lightweight characteristics, it is suitable for products in the transportation sector, such as automobiles and aircraft, which require high energy efficiency. In recent years, the introduction of carbon fiber composites in the construction field for seismic reinforcement has also been considered. Although it is an expensive material, recently, low-cost and high-quality recycled CFRP has been developed. Additionally, there are many composite materials formed and bonded with steel plates and other materials as new structural materials, and we are also engaged in the extraction and cutting of test specimens. Carbon fiber reinforced plastics have very poor machinability, leading to various challenges such as tool wear and interlayer delamination. However, through Yokoyama Kiko's unique technology, such as Reduce Piercing, it is now possible to easily pierce materials that are prone to chipping and cracking during conventional high-pressure piercing, saving time and materials while maintaining structural integrity without causing interlayer delamination or delamination in the workpiece. It is ideal for cutting lightweight, high-strength materials such as carbon fiber plastics, carbon fiber reinforced thermoplastic plastics, glass fiber reinforced plastics, laminated materials, marble, other stones, and glass.

The surface shows some peeling of the protective sheet at the initial penetration points, but the backside can be cut without almost any peeling. This is aluminum thick plate water jet cutting. Although it is thin, aluminum tends to easily form a natural oxide film when exposed to air, so after a certain amount of prolonged processing, it becomes waterlogged. Therefore, we want to protect as much as possible, except for the cut surface where the base material is exposed. Of course, with dynamic water jet cutting, the cutting head is automatically tilted to eliminate taper, reducing water flow delay and taper, allowing for high-precision cutting.

Developed as a substitute for deformed or functionally impaired joints, it is composed of various materials such as ultra-high molecular polyethylene, cobalt-chromium alloy, titanium alloy, and ceramics, each utilizing its unique characteristics. Continuous improvements have been made, enhancing durability with the latest technology, and it is said to have a lifespan of approximately 20 years. The cutting of composite materials showcases the true capabilities of water jet cutting, allowing for verification without applying stress by cutting through the adhesion and voids between materials.

A cost-effective car speaker that incorporates high-performance carbon fiber in the diaphragm. The request was for a complete equal division with center cuts, but due to concerns about the retention rate of each part after cutting, a 90-degree opening cut was proposed. The separated side retained almost its original shape except for the cutting width (cut allowance, kerf width). However, even with the insertion of special stabilizing materials in the frame (unstable areas) and the magnet section to fill the gaps, there was still some impact on the interlayer and cutting surface near the cutting width (cut allowance, kerf width) due to the state of jet water flow diffusion after penetrating through the layers, resulting in a lack of clarity and a completely vertical surface.
