角丸金属 Product Lineup

The left photo shows the side view captured with tweezers. Outer diameter approximately 10 mm Inner diameter 8 mm, tolerance 2 microns Thickness 0.02 mm Processing thin plates is difficult due to many issues such as chucking and bending, but we have succeeded in ensuring tolerances and mass production through jig manufacturing. *For more details, please download the PDF or contact us.*

The outer diameter of the straight part at the tip is φ0.75. Beyond that, there is a tapered section at a 60-degree angle with a flower-shaped uneven surface. It is mainly used in processes related to the manufacturing of watches and other fine medical devices. *For more details, please download the PDF or contact us.*

As a component for automatic transport systems compatible with clean rooms, we have challenged the limits of processing with "thin," "long," and "high precision," successfully machining shapes that were previously considered impossible. The product introduced here, "Load Bar," features a single non-magnetic carbide block that has been machined into an extremely thin plate shape with a thickness of 0.1mm, a length of 7.5mm, and a spacing of 2.82mm, which was difficult to achieve until now, using our processing technology. We can accommodate various specifications, so please feel free to consult with us. *For more details, please download the PDF or contact us.*

What we are introducing here is the louver punch, a component of press molds. The feature of this product lies not only in the complex shape of the punch surface but also in the sharp-edged finish of the recessed areas, as shown in the diagram. Here, the SKD material is processed with our fine machining technology, finishing the tip of the recess to R0.08 or less. Customers considering high-precision press mold components are encouraged to contact us. *For more details, please download the PDF or contact us.*

This is one of our specialties. We handle the processing of ultra-fine carbide pins ranging from φ0.02×10mm to φ0.08×50mm. These products are used in fields such as micro-discharge and electrode tools for grinding wheel shafts, probes, and electrode rods. For ultra-fine pins, please feel free to consult us regarding materials suited for each application. *For more details, please download the PDF or contact us.*

Our unique processing technology allows for diameters down to φ0.05. We can also process air holes as needed. The inner diameter of the processing varies depending on the material used, but it is possible to achieve φ0.020×0.10 with SUS304, SUS316, and nickel-based alloys, making it applicable in fields such as orifices. Please contact us regarding costs, materials, and any constraints. *For more details, please download the PDF or contact us.*

This is a sample that has been tapered from 70° to 62° by dividing 360 degrees into 32 parts. Due to wire cutting, there will be an R of about 0.1 mm remaining at the bottom of the groove, but compared to electrode discharge machining, it is cost-effective as it does not require electrodes and the processing is faster. The materials used are SUS, carbide, and general steel. *For more details, please download the PDF or contact us.*

The photo shows a test processing that has been enlarged to the specified dimensions. In this processing, the width of the islands remaining inside the holes was successfully reduced to 0.2 mm or less. A plate of 0.2 mm or less penetrates to a depth of 30 mm. We aim to make it even thinner and longer by changing the conditions. *For more details, please download the PDF or contact us.*
