The claws are automatically closed or opened under the control of the hydraulic system

Normally used to support the very thin workpiece,such as medical parts

Coolant system :

Including oil tank, Auto chips converyor, Paper filter , Oil chiller, High pressure  pump groups, etc. ;

Adopt vertical structure , save space ;

The pressure,level,temperature and flow of cutting oil is displayed on the CNC operation station.

Lubrication System :

The linear guide rail sliders, screw nut, and spindle are uniformly lubricated by the auto lubricating pump station timely and quantitatively ;

Has low-level alarm function .

Electric cabinet :

Adopt America Rittal structure, won’t deform;

Main low-volatage electric componets use SCHNEIDER brand ;
