Applications/Examples of results

Press molds, press mold components, and industrial machine parts are the main applications. Recently, there has been an increase in the use of hardened materials like SKD11 for wear-resistant components such as sliding surfaces. There are successful cases where parts that were traditionally made from materials like SS400 or S50C and treated with hard chrome plating have been changed to hardened SKD11 materials, and further plated, achieving product lifespans that exceed those of conventional methods.

Detailed information

Processing of a φ0.6 hole SKD11 HRC60 Composite processing of machining, wire cutting, and grinding. Furthermore, the hole diameter is φ0.5 with h6 tolerance. This quality assurance is made possible by the presence of high-precision image measuring instruments.
SKD11 hardened material HRC60 This is the processing content where our technologies for wire cutting, machining, and grinding are most effective. Groove width tolerance 5μ.
Aluminum processing It is a cutting process using a machining center.
