This deep hole powerful honing machine is equipped with PLC controller or CNC system (optional), linear rolling guide way, AC servo motor, grinding rod adopts stepless speed regulation, stable commutation, convenient speed regulation, easy to ensure the accuracy of hole size, and reduce labor intensity. In the honing process, the sand rod and the workpiece always maintain constant pressure, so that the sand rod can be strongly ground. It ensures the high efficiency of deep hole machining, and is suitable for rough and fine honing of general cylindrical deep hole parts. This type of machine tool can also be used for partial honing to correct the taper and ellipticity of parts and the partial hole error.
