VG850 Vertical Universal Grinding Machine

Vertical Advantage: Eliminates gravity-induced deformation, ensuring superior roundness and easier workpiece centering.

Single-Clamping Efficiency: Complete internal, external, and face grinding in one setup for maximum geometric accuracy.

Sub-Micron Precision: X-axis full closed-loop control with 0.0001mm resolution scales and active thermal management.

Smart Automation: Equipped with a 6-station ATC (Auto Tool Changer) and Siemens servo drives for seamless, high-volume production.

Dual-Position Spindle: Flexible 0°/22.5° indexing to switch between flat and angular grinding scenarios instantly.
