Precision Groove Accuracy ±0.003mm Non-magnetic Tungsten Carbide Drive Shaft for Semiconductor and Medical Equipment

Groove Accuracy ±0.003mm Non-magnetic Alloy Semiconductor And Medical Equipment Dedicated Drive Shaft

The grooved shaft is precision-manufactured from WC-Ni non-magnetic cemented carbide. By replacing cobalt with a nickel-based binder phase and utilizing nano-scale groove processing technology, it simultaneously addresses the magnetic interference and positioning accuracy issues of traditional drive shafts. This enables superior transmission performance with zero magnetic interference, precise positioning, and long-term stability in magnetic field-sensitive environments such as semiconductor equipment and medical instruments.
