GD-12S High precision centerless grinder machine

The base of the centerless grinding machine is made of high-gradecast iron (F30), which has been heat-treated to ensure no thermaldeformation after long-term use. The design of double V-shaped sliderails has been precision scraped to ensure long-term accuracy.

The direct-connected drive motor reduces the number of transmissionlinks and ensures the rotation accuracy of the adjustment wheel.

Product details

High precision centerless grinder GD-12S
The main shaft is a three-support structure of bearing pads, and the original Jianchang main shaft in Taiwan has a runout of less than 0.002mm. The infinitely variable speed guide wheel structure can adjust the appropriate feeding speed according to the diameter and length of the workpiece to ensure the roughness of the workpiece.
