This machine tool mainly uses the periphery of the grinding wheel to grind the flat surface of the workpiece, and can also use the end face of the grinding wheel to grind the groove and flange side of the workpiece, with high grinding accuracy and smoothness. Suitable for grinding various precision parts and molds, it can be used for precision machining in mechanical processing workshops, machine repair workshops, and tool workshops.
Machine tools have the following characteristics:
*The machine tool adopts a cross drag plate mobile type, with small thermal deformation.
*The longitudinal movement of the workbench is driven by a variable variable direction vane pump and adopts a closed hydraulic system, which ensures smooth movement, low noise, and low oil pool temperature rise.
*The transverse guide rail of the trailer adopts roller guide rail, and the feed is controlled by an AC variable frequency motor with stepless speed regulation, which can achieve fine intermittent and continuous feed.
*The grinding head spindle bearing adopts a small hole throttling chamber return oil static pressure bearing, which has high rotation accuracy and long service life.
