Common Problems in CNC Machining and Longterm Mould’s Solutions
Longterm Mould has been engaged in CNC machining for many years. The following are the most common problems we have encountered when customizing parts for customers over the years and our solutions. We believe that summarizing and organizing errors can promote the improvement of the quality management system and improve the quality of our services.
In addition, for our customers, not only can we learn in detail about Longterm Mould’s attitude towards quality management and its determination and measures to solve problems. It can also help customers understand and analyze the reasons why parts are unqualified, help to communicate specific issues with suppliers in the future, and quickly communicate and solve problems where parts are unqualified.
Low processing efficiency
Causes:
1. Unreasonable cutting parameters: the cutting speed and feed are set too low, resulting in the prolongation of the processing time.
2. Improper tool selection: The cutting performance of the tool cannot be fully utilized, or the tool is changed frequently, increasing the assistance time.
3. Unreasonable programming: the machining path planning is not optimal, and there are problems such as repeated cutting and too much empty stroke; The program is not standardized, which affects the operation efficiency of the machine tool.
4. Equipment failure and insufficient maintenance: machine tool equipment fails, and the downtime and maintenance time is long; Inadequate equipment maintenance leads to a decrease in machine tool performance and reduced processing efficiency.
Solution:
1. Optimize cutting parameters: on the premise of ensuring the processing quality, appropriately increase the cutting speed and feed to shorten the processing time; However, care should be taken to avoid affecting the machining accuracy and tool life due to too high parameters.
2. Reasonable selection of tools: according to the processing technology and materials, choose tools with good cutting performance and high durability; Use high-efficiency tools, such as compound tools, coating tools, etc., to improve processing efficiency; Reduce the number of tool changes and optimize the tool change process.
3. Improved programming: Optimize machining paths to reduce repetitive cuts and empty strokes; standardize program writing to improve program operation efficiency; Use advanced programming software and programming technology to improve the quality of programming.
4. Strengthen equipment management and maintenance: regularly maintain machine tools and equipment to find and solve potential problems in a timely manner; Establish an emergency plan for equipment failure to shorten the downtime of failure; Upgrade old equipment to improve equipment performance.
