机床主要特点：
  The main features of the machine; 
  1.  机床采用立轴结构。磨削效率高
       This machine is a vertical grinding and milling machine, with high grinding efficiency and accurate.
  2.  工作台移动采用减速电机拖动滚珠丝杠。变频调速，调整方便稳定。
       The table movement of this machine is driving by gear motor and ball screw , 
       stpeless speed frequency control, convenient and stable adjustment. 
  3.  配上专用夹具可实现多角度缸体的磨削
       coupled with special fixtures to achieve multi-angle grinding cylinder and head. 
  4.  机床铸件均采用树脂砂，变形量小外观整齐。
       The casting part of this machine is resin sand casting, deformation is small neat appearance.
  5.  主轴电机为变频电机可实现无极调速
       The main spindle use inverter motor,stepless speed control.
