With a highly experienced design and manufacturing background in centerless grinders, PALMARY present the new bearing type CNC centerless grinder. It is designed and engineered to offer the operational performance & higher accuracy you've come to expect.
The design of high grinding accuracy and high rigidity for 3 axes CNC control (upto 6 axes).
The best configuration for machine bed and structural support ribs makes the grinding accuracies have high stability.
The grinding wheel spindle single bearing holding type equipped with super precision cylindrical roller bearings for the highest rigidity requirement.
The optional high-speed auto loading & unloading attachment could be designed for application. The customs design loading device and outer diameter measuring device are also possilbe as optional for best fuctional performance.
