Large heavy duty CNC lathe, 755mm rail width CK6180 CK61100 CK61125 CK61140

1. High rigidity bed CK61140 heavy machine tool bed is made of high-quality cast iron, the internal rib layout is reasonable, the bed adopts integral type, the guide rail width is 700mm, and the rigidity is good. The sliding guide rail adopts medium frequency quenching, the hardening layer is deep, the hardness is above HRC50°, and the joint surface of the drag plate and the bed is pasted. 2. Introduction of the main drive The spindle of this series of machine tools is manual shift (4 gears) (frequency conversion), and the spindle speed range is (I. gear 15-50 II. gear 40-125 III. gear 80-200 IV. gear 150-315 stepless speed regulation), large torque, good reliability. The spindle bearing adopts domestic (Dalian Keterlow) high-precision bearing 3. Feed system The Z-axis feed system of the machine tool adopts the transmission mode of servo motor driving the ball screw, and the X-axis feed system adopts the transmission mode of the servo motor directly driving the ball screw through the coupling. The main lead screw of the machine tool is selected from the high-precision lead screw of Shaanxi Hanjiang Machine Tool Co., Ltd., and each lubrication point of the feed system is lubricated regularly by the centralized lubrication system. 4. Tool holder This series of lathes adopts vertical four-station electric tool holder, and there is no need to lift the cutter body when the four-station tool holder is rotated, which excludes the intrusion of coolant and cutting to the tool holder when it is rotated, and has high sealing. 5. Electrical system (1) CNC system and servo drive system The CNC system of the machine tool adopts a wide numerical control system, which can adapt to high-efficiency, high-speed, high-precision machining, and has the characteristics of convenient operation, complete functions and high reliability. (2) The electrical cabinet adopts a fully enclosed type.

The tailstock consists of two parts: the upper body and the lower body. The upper body is equipped with a sleeve and a sleeve fast and slow movement mechanism. The tailstock sleeve cone hole of the machine is 6 on the Mohs scale and can be used with a Mohs 5 tip if attached to the cone sleeve. The tailstock of the machine tool has the characteristics of high precision, strong bearing capacity, long maintenance cycle and reliable work.

CAK61140 machine bed adopts high-quality cast iron, the internal rib layout is reasonable, the bed adopts split type, and the rigidity is good. The sliding guide rail adopts medium frequency quenching, the hardening layer is deep, the hardness is above HRC50°, and the joint surface of the drag plate and the bed is pasted.
