【Aluminum Machined All-Directional Mirror】 We consistently prototype and manufacture conical mirrors used for all-direction (360°) image acquisition, from aluminum cutting to mirror finishing. The development was prompted by inquiries at exhibitions regarding the high cost of glass all-direction mirrors and the difficulty of adding screws at arbitrary positions. Due to its conical shape, there is a challenge in achieving mirror surface quality because the peripheral speed decreases near the apex during turning processes. Therefore, we have established a process that includes equipment updates (introduction of a multi-tasking CNC lathe), and we currently achieve practical mirror surface quality through the combination of turning → light buffing → electropolishing. Although we are still in the improvement phase, we are continuously working towards the goal of "achieving a mirror surface solely through turning processes." Please let us know your applications and required quality, including glass mirror alternatives, weight reduction, and ensuring flexibility for additional processing.

We support micro-hole machining with a machining center for extremely small diameters. We have a track record of processing fine holes required for fluid control components such as nozzle heads and orifices, and we can handle machining down to φ0.05mm (50μ). In a sample, we performed through-hole machining of φ0.05mm on the apex of a conical cone with a bottom diameter of φ1mm and a height of 0.7mm. We will propose optimal conditions based on factors such as hole diameter, depth (thickness), material, and quantity. Please consult us if you have any issues with micro-hole machining.

We support machining of three-dimensional shapes using CAD and CAM. We mainly manufacture using a 5-axis machining center, and we can also accommodate requests for machining curved and complex shapes. Additionally, we can process data from 3D XYZ coordinates, so even if there is no CAD data, production may be possible depending on the conditions. We will propose the optimal machining method based on the shape, material, required precision, and quantity. If you have any issues with three-dimensional shape processing, please feel free to consult us.

We move between NC lathes and machining centers to handle processing across multiple surfaces all at once. We can also accommodate processing that involves only lathes or only machining centers, with all work performed by experienced craftsmen. Our production mainly focuses on small lots of various types (around 100 pieces per month), primarily using aluminum and stainless steel, while we also consider difficult-to-machine materials upon confirming the conditions. If you have any issues with multi-surface processing, please feel free to consult us.

This is an example of manufacturing a thin aluminum ring through cutting processing. The ring has a difference of 3mm between the inner and outer diameters and a thickness of 3mm, making it prone to warping and vibration during processing. Conventional turning processes often result in warping after machining, making it a challenging task. Therefore, our company used specialized jigs to process the ring without causing distortion or warping. We can also propose processing methods using specialized jigs tailored to customer specifications such as surface roughness and tolerances. Please consult us if you are having difficulties with thin material processing.

Hollow shapes with a wall thickness of about 1mm and specified surface roughness for the inner and outer diameters are prone to warping and vibration during processing, making it difficult to achieve dimensional tolerances. Our company uses jigs to perform cutting operations on specified areas from hollow work blanks. By conducting all shape processing through cutting, we ensure the necessary dimensional accuracy and adopt methods that minimize warping. We will inquire about the processing methods according to the surface roughness and tolerance requirements for the inner and outer diameters and respond while consulting with you.

We received an inquiry from a customer asking if it was possible to manufacture an integrated part that was being processed on a machining center using an NC lathe. The material is SUS304, and due to the deep cutting area of the inner diameter, there were challenges such as long processing times and high costs, making it unsuitable for mass production with machining center processing. In transitioning to an NC lathe, we organized the challenges, including material distortion during processing and selecting cutting tools that would not break even with deep cuts. Through trial and error, including changes to the cutting method and cutting tools, we established a new processing method. As a result, we were able to reduce costs to about one-third and make mass production possible.

Have you ever experienced that even though you arranged individual parts according to the drawings, the required precision was not achieved after assembly? Even if the parts are precise individually, the product dimensions can be corrected during assembly, leading to deviations from the required precision. At our company, we leverage our experience in parts manufacturing within the assembly department to propose solutions that balance assembly efficiency and post-assembly precision, after confirming the part shapes and assembly methods. Please let us know your current challenges.

Our company specializes in precision machining of round parts (cylindrical shapes) and has experience in processing shafts, rotors, and more. While we also accommodate square parts, we optimize process design and machining conditions primarily for round parts, accepting orders for prototyping to small lot production. We possess various machining equipment, including 5-axis machining machines, and can propose machining methods tailored to your needs. For examples of our work, please refer to the images on our company website. The size range we can handle is approximately 20 to 250 mm for square parts and 20 to 200 mm for round parts.

We provide high-precision and stable quality orifice processing of nozzle heads based on the drawings supplied by our customers. Orifice processing requires advanced machining techniques, especially for small-diameter through holes and edge shapes directly related to flow characteristics. Our company can meet precision requirements in the tens of microns by setting optimal processing conditions with our equipment and skilled technicians. Additionally, we carry out cleaning, deburring, and inspection in-house consistently after processing, ensuring meticulous finishing down to the details that affect flow performance and appearance quality. We also offer suggestions for processing methods tailored to materials and applications, providing flexible support from prototyping to mass production. We promise to accurately reflect our customers' design intentions and contribute to the creation of reliable nozzle head products.

This is an example of a thin-walled aluminum case manufactured through cutting processing. This product has a very thin wall with an inner and outer diameter difference of 2mm and a thickness of 2mm, making it a challenging shape that is prone to warping and distortion depending on the workholding method during processing. Our company used air chucks and specialized jigs instead of hydraulic methods to process it without causing warping or distortion. We can also propose the optimal jigs and processing methods according to customer specifications such as surface roughness and tolerances. If you are facing difficulties with thin-walled processing or thin material processing, please feel free to consult us.

This product is a storage case made from aluminum material. It is manufactured using a complete machining process with a 3-axis machining center. The case is machined from square material, with high precision processing of the flange outer shape, mounting holes, central cylindrical pocket, and stepped inner diameter section. To ensure the positioning accuracy of the sensors, the inner diameter section is managed for dimensional accuracy and concentricity through finishing processes. As needed, re-gripping is performed to ensure overall dimensional accuracy and flatness.

This product is a fluid connector component made from aluminum material, manufactured through integrated machining using a lathe and machining center. Its structure, which does not use welding or press-fitting, ensures high strength and airtightness. We prioritize the internal quality, which is the most important aspect of fluid components, and thoroughly address burr removal at intersecting holes and chip residue prevention. To suppress aluminum-specific welding and burr lifting, we use aluminum-specific tools and optimal cutting conditions to achieve stable surface roughness. Additionally, the mounting flange surface is processed with consideration for distortion caused by clamping, ensuring stable flatness.

In manifolds that handle fluids such as ink, the finishing quality of the internal flow paths is very important, not just the appearance. If the finishing is inadequate, it can lead to issues such as variations in flow rate, fluid stagnation, and the generation of bubbles. Additionally, even slight burrs can cause nozzle blockages. To prevent such problems, our company pays special attention to the finishing quality of the inner diameter during processing. After machining, we carefully check for any remaining burrs or foreign substances. We deliver quality that can be used with confidence. Furthermore, we also consider the surface roughness of the sealing surfaces, achieving a finish of approximately Ra0.8 through cutting processes alone. We value the precision and quality that support stable sealing performance.
