Structural Features:

1.Big basic parts such asthe lathe body, the columns, the table, the slide carriage, the headstock, and the back tail barrelare all high-strength resin bonded sand iron castings and receive two times of heat ageing treatment.

2.The Main Shaft: the main shaft consists of a boring shaft and a milling shaft with an imported main shaft bearing. The main drive system, which integrates an AC servo motor and two-stage mechanical gear shift, enables stepless speed regulation.

3.The Material Forming the Main Shaft: 38CrMoAlA. The surface of the main shaft undergoes nitrogen treatment and finishing with a hardness of above HV900.

4.Swivel Table: the swivel table can be positioned at any angle. The rotor axis adopts a twin-row cylindrical roller bearing, and the upper part of the shafting adopts a central unloading device. A swiveling feed mechanism is driven by an AC servo motor; the gear reduction box having a drive structure that double pinions preloaded by a butterfly spring drive a girth gear can automatically eliminate the gear drive gap and consequently ensure higher drive precision.

5.The Guide Rails: a Schneeberger MR heavy-duty roller straight line guide rail made in Switzerland is adopted for X,Y,Z,W-direction guide rail, a plastics sticking slide rail for B-direction guide rail;

6.The Feed Mechanism: the feed mechanism, which adopts X, Y,Z, W coordinate feeding modes, is driven by an AC servo motor.

7.The Balancing Mechanism: the headstock adopts a counterweight balancing device with two-point suspension, double-guide and rollers.

8.The Hydraulic System: famous brand hydraulic elements with their mounting size meeting international standards are adopted.

9.The Lubrication System:the X,Y,Z,B,W coordinate guide rails and the ball screw nut pair are lubricated by an automatic lubrication device with set time and fixed quantity; a main shaft transmitting gear and a bearing thereof are lubricated by circulating cooling oil; and the main shaft bearing and the screw bearing are lubricated by grease.

10. The Electric System: a SIEMENS840D system is adopted. The system, which adopts six-shaft control and free four-shaft interlock with a hand held control unit, can carry out control and management of the tool shed and gauge head of a facing head.

11.The detecting element: the X , Y , Z axes adopt grating rules and B axis adopts grating circular to form fully closed loop position detection; and the W axis adopts a coder to form semi-closed loop position detection.
