2. Main character of machine

2.1 machine layout

This machine is Double column gantry structure, mainly composed of table, gear box, gantry, cross rail, two tool head, hydraulic device, coolant system, chip conveyor, semi-closed chip cover and electric system. The cross rail move along the guideway of column up and down, two tool heads are used in this machine, the whole system is all-closed control.

2.2 main structure and performance

2.3 main transmission system

The main transmission system is driven by SIMENS servo AC motor, the hydraulic cylinder push the engaged gears to change the speed of table, for that, the table can have 2 stsps and variable speed in between 0.63 and 63r/min,when operating under milling and indexing, backlash of table is available.

2.4 tool head

Left milling tool head is 3 level structure, composed of cross saddle, swivelling saddle and ram. The right turning tool head is four position electric turret. In the middle of ram of left milling tool head, milling driven device is set,it is driven by 12KW servo spindle through the gear box to drive the milling spindle to rotate,the milling tool is clamped by butterfly spring and released by pressure oil.At the end of the ram is gear plate, the angular milling head can be directly assembled on it. All the support bearings of ball screw are made of INA in Germany.

2.5 3CNC system

SINUMERIK 840D,SIMODRIVE 611D digital driven system and SIMATIC S7 PLC are used to ensure the machine can have the function of 3 linked axis work simultaneously, that is X, Z, C axis..

3.Accuracy and tolerance
