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.
Broken knives and broken blades
Causes:
1. Excessive cutting force: Improper selection of cutting parameters, such as excessive cutting depth and rapid feed, resulting in cutting force exceeding the tool’s capacity.
2. Tool material and quality issues: The tool material is not suitable for processing materials, or the tool itself has quality defects, such as internal cracks, uneven structure, etc., which reduces the strength and toughness of the tool.
3. Serious tool wear: The tool is not replaced in time and is excessively worn, resulting in a decrease in tool strength and easy to break or chip.
4. Unreasonable processing technology: improper design of the machining path causes the tool to be impacted during the machining process; Uneven machining allowance will also cause uneven force on the tool.
Solution:
1. Reasonable setting of cutting parameters: according to the characteristics of the tool and workpiece material, reasonably select the cutting parameters to avoid excessive cutting force; During the machining process, the cutting speed and feed can be appropriately reduced to reduce the tool load.
2. Choose high-quality tools: Choose tools with reliable quality and suitable for processing materials; When purchasing tools, strictly check the quality of tools and avoid using defective tools.
3. Timely replacement of tools: Replace tools in time according to the service life of the tools; During the machining process, closely observe the wear of the tool and replace it in time when the wear is serious.
4. Optimize the machining process: reasonably design the machining path to avoid unnecessary impact on the tool; For workpieces with uneven machining allowance, step-by-step machining can be used to make the tool force uniform.
