Technical Description


CBK50 series CNC lathe is an economic CNC lathe with two synchronized axes and semi-closedloop control. 


It can be used to process various shapes of disc parts, ring parts, shaft parts, precision and complex shape parts, which can meet the requirements of high-precision machining of inner and outer circles, steps, cones, spheres and threads. The control system controls the tool path and tool change. Except for the manual loading and unloading, the rest of the processing work cycle is completed automatically, with the tool path display function. 


It is suitable for turning, boring, drilling and tapping all kinds of ferrous materials and non-ferrous metal such as stainless steel and alloy steel. 


The machine tool is flexible in configuration, and can be equipped with hydraulic chuck and hydraulic tailstock according to the requirements of the process, so as to be suitable for the production of multiple varieties and specifications of parts. 


CBK50 series CNC lathe is an efficient and cost-effective processing equipment.


  1. 45 ° slant bed structure, coated and hardened box guide way, smooth chip removal, convenient clamping for workpiece.

  2. The bed and base structure of high-strength cast iron has enough rigidity, good vibration absorption and thermal stability.

  3. The guideways of saddle and cross sliderare coated with Turcite-B. The guideway of the bed is hardened in medium frequency and grinded precisely, which can realize the rapid movement and sustain good accuracy.

  4. Large spindle bore, precision through-hole structure of spindle and precision spindle bearings. It is assembled under constant temperature and purification environment. After precise dynamic balance test, it can ensure the stable running and the maximum speed up to 1620 rpm.

  5. The spindle motor adopts high-performance servo motor. The headstock can achieve constant linear speed via manual 3-shiftgear change and stepless in each shift, ensuring that the machine tool has good cutting performance within the spindle speed range 20-1620r / min.

  6. The protection cover of the machine tool is semi closed for. There is enough space for the lifting of large parts. It is convenient for loading and unloading, and the whole machine is good looking.

  7. The lubricating system can make each lubricating point of the machine tool get reliable and sufficient lubrication, and the interval of oil filling can be adjusted. At the same time, the system can monitor the low-level state of the lubricating oil and display the oil level alarm.

  8. The safety performance of the whole electrical system conforms to GB / t5226.1-1996 electrical safety standard, and the electrical system has the function of fault diagnosis. When the fault occurs, the fault diagnosis content can be displayed on the screen.

  9. Centralized operation panel, height of loading and display fully reflects the human requirements of ergonomics, making the operation more convenient and quick.

  10. Modular design, compact structure, convenient chip removal, reasonable layout, convenient maintenance, pleasant appearance.
