Long Bar Grinding-High Precision CNC Centreless/ Cylindrical Grinding Machine

Product Description

Machine tool characteristics
Machine tool characteristics
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.
2. The drive motor of grinding wheel lies in the rear side, to reduce vibration.
3. The guide wheel is driven by worm and gear, so it can bear the force uniformly, with stepless variable speed.
4. Guide wheel platform & guide wheel system of grinding and feeding:
Three layer structure. The superior layer is cone adjustment turntable, the middle layer is feeding guide rail, and the inferior layer is guide rail of guide wheel platform.
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.
