As a professional in manufacturing, we provide technology, quality, and excitement to our customers.
Typically, when machining holes smaller than the plate thickness, cutting processes were generally used. At Arikawa Manufacturing, we achieve small-diameter holes up to about 60% of the plate thickness using press processing, even under conditions where the hole position is close to the edge of the plate. While it is easy to produce parts with 100% shear surfaces using the FB (Fine Blanking) technique and specialized equipment, it can be costly. Arikawa Manufacturing has made it possible to achieve 100% shear surface production in a single press operation. The "thread feeding" part, which is critical for textile machinery components, requires a high level of precision in finishing. By designing molds that consider the finishing of 100% shear surfaces and the workpiece movement during R pressing, we have achieved a smooth shape that does not break the thread when it passes through. Traditionally, thick gears could only be made through machining, but now they can be produced through pressing with a finish of 100% shear surfaces, high dimensional accuracy molds for leaf punching and holes, and precise riveting technology (core misalignment tolerance of H8 or less).

basic information
【Features】 ○ Press processing of small diameter holes → Small diameter holes up to about 60% of the plate thickness can be achieved through press processing, even under conditions where the hole position is close to the edge of the plate. ○ 100% shear surface in one press → It is possible to produce a 100% shear surface in a single press operation. ○ Smooth finish of product cross-section → Achieves a smooth shape that does not break even when a thread passes through. ○ Product side surfaces are as beautiful as machined surfaces → Thick gears that could only be made through machining can now be produced by pressing. ○ High-precision press processing of large diameters (φ400) → Guarantees inner and outer diameter tolerances of ±0.2 for large diameters (φ400) through press processing. → Achieves 192 divisions with a division error of ±0.2. → This results in a 50% reduction in initial costs compared to conventional machining. ● For more details, please contact us or refer to the catalog.
