Bias cut plunger
- Purpose of Use：
- Contact probe
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.
Mostly BS, BeCu, Pb, SK, and SUS, but also others including SCr420, aluminum, resin, kovar, precious metals, etc.

NC Micro Cutting / Case Study
We are able to handle the ultra-fine cutting inφ0.025mm-class, and we can handle mass production as well.
A rice grain and a fabricated component (φ0.05mm).
A rice grain, and two fabricated components, one is φ0.08mm, and the other 6mm in length.

Example of a whole finish (bias cut)
Due to our proprietary fabrication technology, we can reduce the occurrence of burrs.
Fabrication section of crown tip (enlarged)
integrated barrel w/ side hole (crown with side hole on back)
Ultra-micro holes (from as small as φ0.09mm in diameter) can be fabricated. Even the inside surface is smooth and clean.
Interior of fabricated hole (enlarged)
Hold diameter 0.06mm, depth 1.0mm
Due to our proprietary process management, we can stabilize the accuracy of the dimensions.
Through our collaborations with partner companies, we offer a thorough quality assurance that is in line with various types of surface processing.
