Precision engraving machine processing technology occupies a central position in the modern manufacturing industry, and its high precision and high efficiency make it widely used in the processing of a variety of metal and non-metal materials. However, in cnc finishing engraving machine processing process, still may encounter some process problems, these problems will affect the processing quality, efficiency and even cost. This article will detail some common process problems in cnc finishing machine processing and their solutions to help engineers better master and apply this technology.

1. Workpiece positioning and clamping problems

In cnc finishing machine processing, workpiece positioning and clamping is the basis for ensuring machining accuracy. Incorrect positioning or clamping of the workpiece may lead to machining errors, or even cause the workpiece scrap.

Solution: Use suitable fixtures and positioning devices to ensure that the workpiece is stable and accurately positioned during machining. For complex shapes, consider using customized fixtures to improve positioning accuracy.

2. Tool Selection and Wear

Selecting the right tool is critical to improving the efficiency and quality of cnc finishing machine processing. Improper selection or excessive wear of cutting tools can lead to degradation of machining surface quality, inaccurate dimensions, or even damage to the workpiece or machine tool.

Solution: Select the appropriate tool type and material according to the material hardness and machining requirements. At the same time, check the wear condition of the tool regularly and replace the excessively worn tool in time to maintain the machining quality.

Rico can provide various types of cutters for wood, metal, acrylic, marble, etc. The cutters are made of high speed steel, tungsten steel and diamond. Please refer to our tooling website, if you can't find it on the website, please contact us for more information.

3. Machine tool vibration

cnc finishing machine vibration in machining is a common problem, especially in high-speed machining. Vibration not only affects machining accuracy, but also reduces tool life and machining efficiency.

Solution: Ensure that the machine is in good condition and regularly maintained. Using the right tools and cutting parameters can reduce vibration. In addition, the use of anti-vibration devices or software can also effectively reduce the impact of vibration.

4. Improper setting of cutting parameters

Improper setting of parameters such as cutting speed, feed rate and depth of cut can affect the efficiency and quality of cnc finishing machine processing. Too high or too low cutting parameters may lead to processing quality problems, such as undercutting, overheating, workpiece damage.

Solution: Reasonably set the cutting parameters according to the workpiece material, tool material and machine performance. Conduct test cutting before starting mass production to find out the best combination of cutting parameters.

5. Programming Errors

cnc finishing machine Programming errors are a major cause of machining errors. Errors in the program may lead to tool path deviation, which may affect machining accuracy or cause crashing accidents.

Solution: Use professional CAD/CAM software for programming and simulation verification before formal machining. Add program review session by experienced engineers.

6. Material Issues

Internal stresses in the workpiece material or material non-uniformity can also affect the quality of cnc finishing machine processing. Internal stresses may cause deformation of the workpiece during machining, while material non-uniformity may lead to inconsistency in the quality of the machined surface.

Solution: Select a material supplier with reliable quality and ask for a material performance report. For materials with known internal stresses, perform stress relief treatment before machining.

The breakthrough of precision engraving machine processing technology lies in the continuous optimization and intelligent upgrading of process details. By systematically solving the core problems of positioning, tooling, vibration, etc., combined with data-based management and intelligent control, it will promote the processing accuracy and efficiency to a new height, creating greater value for high-end manufacturing.
