vertical machining centre

vertical machining centre    VMC855

The machine features:
The Pyramid gold proportion structure design. The main casting by the rib reinforcement, on various processing conditions, have the best accuracy.
Outstanding remarkable mechanical structure, in addition to prolong the service life of the machine, thermal stability, and enhance the damping capacity.
The unique base slide design, saddle stroke without drape phenomena, load, slide design mining width gauge high rigidity and stability.
The Japanese scraping technique combined with font scraping and shaped oil groove unique *, a uniform oil film let the sliding surfaces, eliminating the starting viscosity of fast moving floating phenomenon and cutting feed.
Mining high frequency heat treatment the sliding surface, sliding surface attached TURCITE-B imported wear plate.
That can match with direct drive 12000 rotary spindle.
That may depend on customer demand with BT-40 or BT-50 spindle.

In common:
The main structure of casting 1 machinery, in addition to made of cast iron with high quality; the tempering treatment, eliminate stress, then the finite element analysis of advanced science, structure stress situation by computer simulation, to ensure that the mechanical rigidity, stability and anti-seismic ability best.
2 three axis motor and ball screw by direct drive, pre tension, no backlash.
3 precision ball screw for modular assembly. The ball screw of the parallelism and perpendicularity through precise calibration to ± 0.01mm (full length).
4 spindle cooling system - the spindle oil cooler, to prolong the service life of the main shaft. In addition, the machine show the high efficiency and high precision machining characteristics.
5 high rigidity spindle spindle adopts P4 super precision bearings, suitable for all kinds of precision machining, and the high speed cutting.
6 spindle head with circulating oil cooling system, effectively avoid thermal expansion problems, ensure the machining accuracy.
7 automatic lubricating system lubricating system can automatically, and precise oil to oil distributor, ball screw and slide.
8 cover sheet metal - airtight cover meets the requirements of environmental protection and the CE standard, while providing the operator more comfortable operating environment.
9 full set strict quality inspection: laser detection, Ball Bar circular detection, heavy cutting test, 3D test, semi solid die cutting 45 degree parallel milling and 2D circular cutting.
