Product Features

High-precision, high-rigidity four-axis CNC centerless grinder.
The bed, structural support ribs, and other components are optimally configured to create a high-rigidity and precision-stable mainframe. It employs a high-rigidity single-handle spindle with ultra-precision double-row roller bearings.
The dual-sided sliding plate design can also be paired with a stop-grinding device, or equipped with a variety of high-speed feeding and receiving devices.
It achieves high operational performance and can be equipped with a supply device and an outer diameter measuring device.
