CK7550 CNC lathe

Features:

High-efficiency lathes for large chucks and shafts.

1) Adopt 60° inclined bed + base structure, with high strength and good shock absorption; Multiple aging treatments effectively inhibit the deformation and stress caused by cutting force during the machining process;

2) The spindle assembly adopts a combination of precision angular contact thrust ball bearings and double-row cylindrical roller bearings, and the dynamic balance is corrected, which can maintain the high precision and rigidity of the spindle; The spindle box assembly passes the running test, adjusts the spindle bearing preload, monitors the spindle temperature rise, thermal deformation, etc., so that the spindle starts quickly, smoothly and with stable accuracy during long-term work;

3) The X/Z axis is directly connected with the ball screw by servo motor, with high feed accuracy and higher machining accuracy;

4) In addition to program control, the clamping and loosening of the hydraulic chuck and the expansion and contraction of the hydraulic tailstock sleeve can be controlled by foot switch, which is convenient and fast; The hydraulic pressure adjustment adopts panel rotary operation, and the dial display, which is safe and convenient to adjust;

5) The guide rail and ball screw pair are lubricated with centralized automatic thin oil, and each node is equipped with a quantitative oil separator, which regularly and quantitatively injects oil into each lubrication part to ensure the uniform lubrication of each sliding surface, effectively reduce the friction resistance, improve the motion accuracy, and ensure the service life of the ball screw and the guide rail pair.
