LK 200M(S)Y Double Spindle CNC Lathe Turning And Milling Compound Machine
The machine is equipped with the double spindle and the auxiliary tool holder, to achieve workpiece rotation docking for secondary processing, reducing the second clamping time.
It adopts high-grade, low-stress, cast box-type horizontal lathe bed, which has excellent mechanical properties and precision stability.
The customized integrated power tool turret has the characteristics of high positioning accuracy and good stability. The standard tool turret can withstand 70Gg cooling pressure and can achieve high-pressure cooling and high-pressure chip breaking.
The feed axes all adopt Japanese THK roller guides, Z-axis type 45.
Y-axis control can be complex shape processing; Back axis can also be cut face machining, without the need for secondary processing in the car drilling.

| Servo electric spindle Conduct finite element analysis of the spindle box, optimize the structure, and use the thermal balance external compensation technology of the electric spindle system. Based on the temperature of the spindle component's steady-state thermal analysis, the thermal ribs are reasonably arranged on the box and cooled by oil cooling circulation to achieve uniform heat dissipation. The thermal stability of the machining process realizes the high stiffness and high precision requirements of the spindle.
