What are the features of Reliable Brothers CK6150 flat bed CNC lathe?
1 This machine tool is optimised and improved on the basis of traditional CK6150, featuring high precision, high speed, and high rigidity. The machine tool is ergonomically designed for comfortable and convenient operation, and the integral protection keeps the environment tidy.
2The bed is made of resin sand casting, and the special widened guideway has gone through many heat treatment processes such as aging and high-frequency quenching, which can maintain the best mechanical precision for a long time and ensure the good machining precision of the machine.
3 The machine tool uses high-precision screws, and the bearings adopt high-quality domestic special rubber contact ball bearings for screws, which are connected with servo motors through elastic couplings, with the advantages of high transmission precision and long service life.
4 The machine tool is equipped with a servo spindle motor, which can realize the infinite speed change within the spindle gear to meet the different rotational speed requirements of workpiece processing, thus optimizing the machining capacity and cutting performance.
Spindle
The spindle box bearing adopts a double row of short cylindrical roller bearings and a two-way thrust ball bearings paired combination design, four auxiliary electrodes with three gears in the box to achieve the gears within the infinitely variable speed, to achieve high torque, high rigidity, to ensure the long-term stability of precision for heavy cutting.
Wider bed
The bed is widened to improve the rigidity; the triangular rib is widened and thickened to increase the contact surface of the drag plate, which improves the rigidity and anti-vibration ability.
Drag plate
 The front of the large drag plate is widened and lengthened to improve the stability and rigidity of cutting 30 per cent on the original basis, and greatly extend the service life of the lathe.
