●Various spindle speed 10~300PRM, driven by servomotor
●Special hydrostatic bearing
●Precision wheel head
●Various grinding application
Overview
The bushing grinder can realize straight cut grinding, shoulder grinding, transverse grinding, end grinding, taper grinding and internal grinding (optional). The multifunctional features enable it to be used for a variety of processing purposes, which can help users save the cost of purchasing multiple machines. The machine is driven by a servo motor, and its spindle speed is within the range of 10~300PRM, which greatly improves its machining flexibility. Thanks to the design of precision wheel heads and special hydrostatic bearings, it can ensure high accuracy and achieve very little wear. This machine is also very easy to maintain, so it can be used for a long time.
