The two slides design centerless grinder is suitable for long bar outer diameter grinding application. The advantages include the work rest fixed in the machine which enable better grinding accuracies for its stability. The grinding wheel spindle single bearing holding type equipped.
High grinding accuracy and high rigidity design for 4 axes CNC Centerless Grinder bearing spindle type.
The best configuration for machine bed and structural support ribs makes the grinding accuracies has high stability. The grinding wheel spindle single bearing holding type equipped with super precision cylindrical roller bearings for the highest rigidity requirement.
Double-side slides design allows to equip the infeed grinding type device, also could arrange the optional high speed auto loading & unloading attachment.
The customs design loading device and outer diameter measuring device are also possible as optional for best functional performance.
