1. The guide wheel shaft of grinding wheel uses double-row roller shaft structure, sealed with grease, free of maintenance. It owns high rotation accuracy & rigidity, it's suitable for high-precision mass grinding. Both of grinding wheel & guide wheel shaft adopt double support structure, so as to ensure its sufficient rigidity.
The guide rail is wide & thick, the fixing surface is plated with chromium, and the mobile surface is stuck with plastic, which owns high rigidity, high precision, high wear resistance & high vibration absorption.
It's driven & fed by ball screw & worm and gear together, so as to ensure the micro-advancing precision.
