How does a CNC lathe work?

1. Before CNC lathes process and produce parts, they need to design and analyze the process plan based on the pattern of the parts to be processed, and then perform programming. The preparatory process should be performed first. If the machining process of the workpiece is long and particularly complex, try not to program it on the lathe. You can use a programming machine or program manually to avoid taking up machine time. For shorter programs, they should also be written on the program list.

2. For the input of processing programs, you can choose the interface for direct communication between the computer and the CNC lathe to input the processing program of the part into the CNC system. Then the tools and fixtures need to be pre-adjusted. Before processing the parts, the tools and fixtures should be installed and adjusted according to the tool and fixture solutions determined in the part processing process design. The machining program is then decoded and calculated by the CNC device. After processing, it becomes a pulse signal, which is sent to the servo system of the lathe, and then drives the relevant parts of the lathe through the transmission mechanism to complete the cutting of the parts. Others will be sent to the programmable controller, which in turn controls other auxiliary components of the lathe, thereby completing the actions of clamping and loosening the workpiece, opening and closing the coolant, and automatically changing the tool. Please refer to the clamping points.

3. StartCNC latheThe process is to start the lathe first, and then start the system. Since some designs are interlocked, the lathe cannot display the corresponding information on the CRT without power. Rotating the reference point. For CNC lathes that use incremental control systems, this step must be performed to establish the motion standards for each coordinate of the lathe.

4. If you need to modify the input program, you need to edit it. At this time, put the mode selector switch to the EDIT position and use the EDIT key to add, delete and change. If the lathe's CNC lathe is locked, the program needs to be checked and re-edited if errors are found.

5. Then find the tool for the workpiece, select manual incremental motion, continuous motion or use manual playback to move the lathe. Align the tool center point with the super starting point of the program and the tool datum.

6. Start coordinate feed and continuously process the parts. Usually, the program in the memory is used, which has a lower error rate than the program on the paper tape. The feed speed during processing can be adjusted by the feed speed. During the processing, you can press the FEEDHOLD key to pause the feed movement and observe the processing situation or measure manually. When finished, press the CYCLESTART button again to resume operation. In order to ensure that there are no errors in the processing program, it is necessary to review it carefully before processing. When machining a workpiece with a plane curve, you can use a pencil instead of a tool to draw the outline of the workpiece on paper, so you can visually see it. If the system has a tool path simulation function, it can be used to check whether the program is correct.

7. The CRT can display various pictures, display the position and program of the workbench or tool, and the status information of the CNC lathe, making it convenient for the operator to monitor the processing process. When the program is completed, if you need to save the program, you can save it in the CNC's memory. If the program is very long, it can be saved by exporting the program in memory to an external device.

8. For part inspection and disassembly, workpiece dimensions should be inspected while the workpiece is still clamped by the chuck. If the dimensions of the workpiece are not up to standard, appropriate tool compensation operations are required, reprocessing is required, and the workpiece is disassembled when the dimensions are up to standard. After all process operations are completed, shut down the machine. When shutting down, the CNC lathe is also shut down first, and then the system is related.
