Working Principle: The spindle is mounted on the guideway frame above the bed. Its front end is connected with the motor, and the rear end is connected with the reducer through the pulley. Motor through the belt drive reducer output gear oil lubrication of high-pressure lubricant to the spindle end face through the overflow valve into the coolant tank circulating coolant cooling and then return to the spindle bearing housing bearing cavity for lubrication and cooling. Deep hole honing machine in the honing process, the abrasive bar and the workpiece always maintain constant pressure, so that the abrasive bar for strong grinding, to ensure the efficiency of deep hole machining, the general cylindrical deep hole parts, rough boring after fine precision honing, if you use the cold-drawn steel pipe, you can directly carry out the strong honing, change the deep hole machining of the traditional process of multi-procedure process methods, deep hole honing machine to improve the productivity. The honed parts are made of cast iron and various types of steel, including hardened workpieces. This machine tool is suitable for honing and polishing of cylindrical deep hole workpieces, such as various hydraulic cylinders, cylinders and other precision tubes.
