Key Points:
1.The body frame is made of natural granite overall and undergoes precise abrasion to ensure the machinery precision and low vibration;    
2. The all-sealed cover, external cutting fluid processing way as well as the residue fluid collection tank make the site clean and tidy; Y axis is provided with stainless steel dustproof cover so as to make it resist corrosion with high rigid protection function and ensure the service life and precision of Y axis screw guide;    
3. X, Y and Z axis adopt high-precision linear guide with ultra-strong load bearing capacity, fast displacement and positioning and high precision;

4. The high precision abrasion ball screw pairs and preloaded screw are high in transmission precision and small in mechanical error within the long period; the body is in independent lubricating system design to ensure all the movement parts are durable;    
5. Internal circulating water cooling main shaft unit is used;    
6. Three independent spindles can make the working efficiency three times higher; three independent spindles in independent fine adjustment structure are used and three workpieces can be processed at the same time. The jig is easy to adjust, the processing precision is high and the production speed is fast; besides, the system is able to use the specific spindle, that is to select any spindle available. The unused spindle does not work so as to save power.    
It is widely used where the time to handle the workpiece is short and the processing time is long. It is able to improve the working modulus and utilization rate of machine tool significantly
