Main characteristics of this machine tools
★ This machine tools is mainly used for grinding of internal hole, stepped hole and internal tapered hole of work piece.
★ Feed and compensation of machine tool is executed by two non-interference drive mechanisms. The feed system hasthe function of fixed-stroke grinding and adopts manual or hydraulic feed method.
★ The machine tools is equipped with fast hopping mechanism. Therefore, the tools does not need to be adjusted after The grinding wheel is withdrawn for measurement or dressing.
★ Intermediate stop device is set for fast backward of work table. The distance of fast backward can be adjusted as required to reduce auxiliary time.
★ The starting hand of work table is equipped with safety interlocking device so as to ensure the safety during assembly, disassembly and measurement.
★ The maximum rotating speed of grinding wheel spindle is 24000r/min so as to improve grinding of small hole.
★ If the user has a special order, the frequency conversion speed regulator of motorized spindle can be modified to grind internal hole with small diameter.
★ This machine is equipped with end face grinding device to ensure the perpendicularity of work piece internal hole and end face.
