The vertical CNC lathe is a high-efficiency metal processing equipment. It has the advantages of high precision, high efficiency, and high quality, and is widely used in various industries. When using a vertical CNC lathe, thread processing is an important process. So, what are the methods for processing threads on a vertical CNC lathe? The following will introduce it to you in detail.
1. Single-tool machining method
The advantages of this method are that the thread cutter can be reused, the rotation speed is low, the processing depth is small, the operation is simple, and the accuracy of thread processing is not high. However, the disadvantage is that the processing speed of this method is slow, which affects the output, and the tool needs to be replaced, which is costly.
2. Multi-knife compensation method
In the multi-tool compensation method, machining tools with different depths are used for thread processing, so that the tool with a deeper processing depth compensates for the deviation of the tool with a shallower depth, claiming the distance error on the spiral line. This method has the advantages of high processing accuracy, fast processing speed, and high output, but it also has the disadvantages of tool replacement and higher cost.
3. CNC gear grinding method
In the CNC gear grinding method, CNC technology is used to control the lathe feed processing tool, providing a more refined and efficient method for thread processing. This method has the advantages of high processing accuracy, fast processing speed, and repeatable processing, but it also involves shortcomings such as the replacement of processing tools and technical requirements for gear grinding operations.
To sum up, the methods for processing threads on vertical CNC lathes include single-tool machining method, multi-tool compensation method and CNC gear grinding method. In actual production, the most cost-effective method can be selected based on the characteristics of the workpiece, processing volume, product quality requirements and other factors to ensure the processing accuracy and efficiency of the thread.
