Development of CK6130 small CNC lathe

At present, economical CNC machine tools are still the most demanding CNC machine tools in China. Utilizing the existing idle old machine tools and transforming them into a new high-efficiency and versatile economical CNC machine tool through numerical control, it is an effective method for revitalizing the stock funds and one of the roads to achieve automation at low cost. The CK6130 small CNC lathe we developed is the exploration and practice of this idea.

1 Working principle CK6130 small CNC lathe consists of two parts: the microcomputer numerical control system and the machine body. When machining the workpiece, firstly program the NC program of the workpiece, then input the CNC program that can be checked into the numerical control device, and then calculate the feed pulse sequence according to the program command by the numerical control device, and then the multi-function NC board performs pulse distribution, and the power amplifier or After the power is amplified by the driving power source, a control signal of the driving device is formed, thereby controlling the rotation speed of the machine tool spindle, starting and stopping, the moving direction, the speed and the displacement of the feeding system, and the selection of the tool, the start and stop of the cooling and lubrication, etc. The tool and workpiece and other auxiliary devices work strictly in accordance with the sequence, stroke and parameters specified by the NC program, thus processing the shape, size and precision to achieve a friendly human-machine interface.

3 Conclusion The CNC system is based on the general industrial control machine. It adopts the powerful motion controller PMAC to undertake real-time tasks such as interpolation calculation, position control and speed control, achieving two levels of openness, making the CNC system have special The system has better human-computer interaction capability and upper-level application system integration capability, which is convenient for manufacturers and users to customize and adjust the system functions, so that the system has better adaptability. The numerical control system has been applied to the development of the SKB2320A wall panel milling machine and has achieved good results.
