Introduction
The Internal Grinder for bearing inner dia. and groove is specially applied for bearing grinding. The workpiece loading, unloading and the workhead movement could operate at the same time in order to shorten the time for setting & adjustment. Machine could equip with vibration feeder or workpiece arranging device in order to have auto loading control.
Machine equipped with Palmary developed conversational control panel (Mitsubishi PLC) for easy operation. The customer could choose to use CNC controller as optional.
Features
- Machine with magnetic workhead centerless support device which allows the loading and unloading workpiece process move quickly and increase work efficiency.
- The customer could use optional accessory CBN grinding wheel for having better grinding results.
- Machine supplied the high precision roller type dressing device to make sure the dressing accuracy.
- According to the workpiece accuracies required, it's optional to add the digital linear or in-process ID measuring device.
