How to process high-precision parts on a CNC lathe?

CNC lathe is a high-efficiency, high-precision CNC machine tool that is widely used in the field of parts processing. In the process of processing high-precision parts, you need to pay attention to the following aspects:

1. Preparation work before part processing Before starting processing, you first need to prepare the CNC program and tooling fixtures required to process the parts. CNC program refers to the instruction code written to control the machining movement of the lathe, which will directly affect the control of machining accuracy. The tooling fixture is a device used to fix and position processing parts. Its design and manufacturing quality will also affect the processing accuracy. Therefore, before formal processing, the CNC program and tooling fixtures must be strictly verified and debugged to ensure that they meet the requirements of high-precision processing.

2. Parameter setting during processing When processing high-precision parts on a CNC lathe, it is necessary to set appropriate processing parameters based on the shape, material and requirements of the part. These parameters include cutting speed, feed rate, cutting depth, cutting force, etc. Properly setting these parameters can improve cutting efficiency and processing accuracy, and reduce deformation and damage during processing.

3. Tool selection and tool wear control Cutting tools are the core tools for CNC lathe processing, and their selection and use have a great impact on machining accuracy. When processing high-precision parts, high-quality, high-hardness cutting tools should be selected, and the tools should be tested and wear controlled regularly. Tool wear will lead to machining dimensional errors and a decrease in surface quality. Therefore, timely replacement of severely worn tools is one of the important measures to ensure machining accuracy.

4. Stability and monitoring during processing When processing high-precision parts on CNC lathes, it is necessary to maintain the stability of the processing process and monitor the processing status in a timely manner. Stability includes the rigidity and stability of machine tools, the rigidity and stability of cutting tools, the fixation and stability of workpieces, etc. Through reasonable fixture design and machine tool adjustment, the stability of the processing process can be improved, thereby improving processing accuracy. At the same time, the machining parameters can be adjusted in a timely manner by monitoring tool wear, changes in machining force and other parameters in real time to ensure the stability and accuracy of the machining process.

5. Management of process documents and records In the process of processing high-precision parts, it is necessary to establish a complete process file and record management system. Including the writing, revision and management of CNC programs; the design and manufacturing application process of tooling fixtures; the selection, use and wear records of cutting tools; the recording of processing parameters and monitoring data; the acceptance and assessment of processing quality, etc. Through standardized management, the continuity and consistency of the processing process can be improved, and the stability and reliability of processing accuracy can be ensured.

In short, processing high-precision parts on CNC lathes requires sufficient preparation, reasonable setting of processing parameters, selection of appropriate tools, maintaining the stability of the processing process, and establishing a complete process document and record management system. Through the comprehensive application of the above measures, the efficiency and accuracy of CNC lathe processing of high-precision parts can be improved and the high-precision requirements of complex parts processing can be met.
