Achieving a thick plate press that can create a shear surface as smooth as a mirror without additional processing!

In any case, a beautiful mirror-like shear surface has been achieved with a thick plate press (0.5mm to 12mm) using a servo press.

The feature is that "we achieve a beautifully mirror-like shear surface with a standard press." Typically, when punching with a press, a fracture surface occurs, and especially when creating precision or mechanical parts from difficult-to-machine materials like SCM or S45C, additional processing to handle the fracture surface created during punching was necessary. However, it has become possible to manufacture thick press parts with shear surfaces comparable to fine blanking, and with a mirror-like finish and smoothness, using a standard servo press. In particular, for thick press parts where additional processing was required to achieve cutting surface precision, there is a possibility of eliminating finishing processes! By utilizing this precision pressing technology for thick press parts, we have achieved high cost competitiveness, including mold costs and processing costs.

Applications/Examples of results

We have a wide range of mass production achievements, primarily for automotive applications and extending to industrial equipment applications. - Plate thickness: 5-6mm, brake-related components - Plate thickness: 6mm, precision stamping of S45C - Plate thickness: 4.5mm, precision stamping of SUS304 gears followed by shaving processing with a tolerance of ±30μ - Plate thickness: 5mm, SPCC, shear length of gear parts over 90% - Plate thickness: 5mm, SPHC, simultaneous processing of outer diameter cutting, hole drilling, and chamfering - Plate thickness: 3.5-4.5mm, SCM415 ring-shaped components, shear length of the outer circumference over 90%. Finished with barrel polishing to a surface roughness of Ra0.4 or less. Rather than forcing a progressive die process to complete the work, we utilize machining centers and high-performance drill presses as needed, allowing for overall improvements in quality and production efficiency. We can propose cost-effective processing that includes precision chamfering, hole drilling, and light milling as required.
