1. This machine is specially used for semi finish milling and finish milling of flat head of heavy roll parts. The processing of two planes, two cambered surfaces, two chamfering and keyways on both sides of the roller can be completed by one time clamping.

2. The main drive of milling head box is driven by AC variable frequency spindle servo motor, and the spindle speed can be adjusted steplessly.

3. The vertical and horizontal feed axis is driven by servo motor.

4. PLC program control is used to input processing parameters through the touch screen man-machine interface on the operation panel. A variety of fixed circulation, easy to operate, easy to master and use.

5. The machine bed adopts the whole four guide rail structure with strong rigidity. The four guide rails are installed with heavy-duty roller linear guide rails.

6. The column adopts the integral door frame structure with strong rigidity and effectively controls the parallelism of the four guide rails.

7. The spindle of milling head box adopts heavy load spindle structure, with high rotation accuracy and strong rigidity. The main shaft bearing adopts the high-precision special bearing of Harbin, tile and Luoyang.

8. Select domestic high-quality heavy-duty grinding ball screw to ensure the position accuracy of machine tool feed shaft.
