The special collet is matched with the center thimble for positioning, which can compensate for the eccentricity of the workpiece by 2mm.
There is a special waterproof sealing ring inside the collet, which is dustproof and anti-cutting fluid, making daily maintenance more convenient.
The Jaw chucks of the oscillating mechanism are heat-treated, hardened, and ground with alloy steel to prolong the service life of the product.
