Machining Accuracy Of CNC Internal Grinding Machine Oct 27, 2017

The internal grinder is mainly used for machining the cylindrical bore, cone hole or other special shaped inner surface and end surface of the workpiece. The inner cylindrical grinding is generally divided into two kinds: the workpiece and the grinding wheel are all turned, the other is the workpiece does not rotate, the wheel for planetary motion The former is used for general hole processing, which is generally used for the hole machining of large workpieces.CNC Internal Grinding Machine

The grinding wheel spindle of the internal grinder is very long, and high-speed rotation, the need for high-speed motor and the life of the spindle bearings, internal grinder machining aperture measurement is more difficult, coarse grinding, semi fine grinding and fine grinding generally using automatic measuring instrument measurement, can achieve the cycle control of spark measurement. The grinding head is moved and swung vertically to achieve the transverse feed of the grinding head. The grinding head can also be adjusted horizontally in the sliding seat of the grinding head, and the workpiece frame is fastened on the base of the machine tool. Because the vertical and horizontal feed only uses a sliding seat, the stiffness and working precision of the machine tool are higher than the traditional sliding surface.CNC Internal Grinding Machine The internal grinder is mainly used for machining the cylindrical bore, cone hole or other special shaped inner surface and end surface of the workpiece.

The workpiece spindle adopts high precision and large contact into the corner bearing, the workpiece speed AC frequency conversion, stepless speed regulation. The Machine tool guide and ball screw are lubricated by lubricating station automatically. and has a sealed cover shell protection. Machine tool can be equipped with cylinder as a fixture power source of the multi-point circular positioning of automatic fixture and a variety of special fixture. The machine tool size control uses the fixed course grinding, and can be matched with grating ruler closed loop control. The coolant filtration uses a magnetic and paper-quality precision filtration device.CNC Internal Grinding Machine
