NC Micro Cutting

By fusing and combining the micro cutting technology and micro measuring technology with more than 120 units of CNC precision automatic lathes, we mainly manufacture and sell rounded micro precision cut items, contact probes and contact probe pins.

Materials used for fabrication

Mostly BS, BeCu, Pb, SK, and SUS, but also others including SCr420, aluminum, resin, kovar, precious metals, etc.

Dimension management

Due to our proprietary process management, we can stabilize the accuracy of the dimensions.

Surface Processing

Through our collaborations with partner companies, we offer a thorough quality assurance that is in line with various types of surface processing.
[Example Track Record]
– beryllium copper: aging treatment, SK materials: heat treatment, hard gold plating, palladium cobalt plating, rhodium plating, lubricant gold plating, composite plating

Aftercare support

Even after delivery, we are able to provide support through submission of various documentations and analysis.
