This is a CNC double coordinates, two-axis associated-action and semi-closed loop controlled turning lathe. It has the advantage of high accuracy, high efficiency and high stability. Mated with advanced CNC system, the machine has the function of interpolating linearity, oblique line, arc (cylindrical, rotary camber, spherical surface and conic section), straight and taper metric/inch screws. It is suitable for processing complicated and precision plates and shafts. The roughness after turning can reach the accuracy of grinding by other grinder.
Adopting 450 slant ground bed, the large section of the bed and the large span of the guide way improves the rigidity of the machine, and both X and Z axis are equipped with high rigidity rectangle hardened guide way.
The transmission system of the spindle adopts A.C servo motor with big vary speed range, the spindle adopts hydraulic two grades stepless speeds,
The lubrication is out cycle watery oil structure. And the machine can realize stepless adjusting speed and constant line cutting.
Both X and Z axis are mated with A.C servo motor which has high positioning accuracy and stable performance. The servo motors are connected with ball screw directly, and the small reversal gap and pre-pulling eliminate the affection of the temperature raise to accuracy.
The tailstock is hydraulic and its spindle can be controlled by CNC system.
Turret: it is 12 tool position, and its repeat positioning accuracy is 0.006mm. if need, the machine can also change to hydraulic turret or servo turret.
Chuck: the chuck is hydraulic power chuck, if need, it can also change to pneumatic chuck.
Hydraulic system: hydraulic system adopts variable impeller pump, the pressure of the hydraulic system is 5. Mpa, the hydraulic elements are all made in Taiwan. The pressure of each cylinder can be adjusted separately and each cylinder has pressure protection device. The wind cooling can assure the machine to work continually.
Chip conveyer and coolant system: oil tank can be separated with chip conveyer, so the oil tank is convenient to clean, coolant system adopt big lift pump, the lift is 17m and the flow is 30L/min. so the processed area of the workpiece can be cooled sufficiently.
Lubrication: adopt centralized lubrication.
The machine has the alarm device and urgent stop button so as to protect the machine, the alarm will be displayed on the screen.
The electric cabinet is mated with air conditioner, and the protection class of the electric cabinet reach IP54.
