The bearing system of main spindle should be roller bearing of high precision: TIMKEN

The Z, X, Y guiding way system is achieved automatic-lubrication hard guiding way.

The turret of machine is 400 four-direction rotate automatically (VDI3425 page 3). The tool holder is according with DIN69881and for turret with DIN5480 (DUPLOMATIC TMY – BR – 20), 20×0,80; the section of tool is 40mm. The location of tool holder is 12×30°.

Lubrication, hydraulic, pneumatic and tool cooling system.

The hydraulic and pneumatic parts use the products of Rexroth.

Power supply:

Three-phase AC: 380±10V% , 50±1 Hz ;
Single-phase AC: 220±10V%, 50±1 Hz .

Servo motors for driving 1FT6 SIEMENS

CNC system: 840D SIEMENS

Measurement system: Z, X, Y axis use HEIDENHAIN optical scales.

The positioning precision at Z direction whole travel P =0.05mm, repeat positioning precision PS=0.01 mm
The positioning precision at X direction whole travel P=0.01mm, repeat positioning precision PS=0.008mm
The main spindle use degree coder. The orientation precision of C axis is ±5″

The X, Y, Z, C four axis are linkage

The control panel has hand-wheel function

Accessories

C type steady with rollers and interchangeable pads.
Diameterf100 -500mm , one piece
