Machine base adopts integral casting, strong shock resistance, not easy to deformation.
Customized CNC rotary milling modular programming system, easy to operate.
The transmissions part of the machine tool adopts the high precision P4 level ball screw of the well-known domestic brand Nanzhu/Hanjiang.
Using the combination cutter head with machine clip, for 4.762 and above ball diameter, it can meet the raceway+oil groove and chamfer molding.
The machine adopts hard rail transmission structure, which can withstand large cutting and impact resistance.
Can be used for all kinds of ball screw soft/hard milling, equipment with pitch compensation function.
This equipment can be selected according to customer products, center frame clamping form, in order to meet the size of the product adaptation processing.
Cutter head design adopts the scheme of compact and fine-tuning of tool bar, which is convenient for tightening of tool bar and consistency adjustment of tool tip rotation circle.
