Centerless Perimeter Grind Processing
High-precision outer peripheral grinding of round bars and prismatic materials
It is a grinding process that prepares the outer circumference of the round bar material by fixed abrasive grain processing.
We are good at processing glass rods and ceramics, and adjust the surface roughness with several types of whetstones with different counts.

With our unique technology, grinding adjustment in 1 μm units and high-precision grinding with a tolerance of ±1 μm are possible.
Since the work piece is supported over the entire length, there is little deflection due to the weight of the work piece, and stable external dimensions are possible.
