What Is The Reason Why The CNC Engraving Machine Cannot Cut Through The Workpiece?

In modern manufacturing, CNC engraving machines are widely used in precision processing of various materials, covering multiple fields from wood, plastic to metal. However, in actual operation, operators often encounter the problem of not being able to cut through the workpiece. This problem not only affects production efficiency, but may also lead to material waste and increased costs. Therefore, it is particularly important to understand the reasons why the CNC engraving machine cannot cut through the workpiece and take corresponding solutions to avoid such problems. UTECH is a professional CNC equipment manufacturer that can provide you with high-performance professional CNC machine tools, and in this article UTECH will discuss in detail the main causes of this problem to help you identify and solve related problems and ensure the improvement of processing quality and efficiency.

3. The influence of the characteristics of CNC machine cutting materials

1. Improper selection of tools for CNC machines

The selection of tools is one of the key factors in the cutting quality of CNC engraving machines. If the tool is not selected properly, especially in terms of material and geometry, it often leads to poor cutting results. For example, for harder metal materials, if an unsuitable tool is used, it may cause insufficient cutting force, resulting in incomplete cutting. In addition, tool wear will also directly affect the cutting effect. Passive tools may generate greater cutting resistance during cutting, causing heat accumulation, which will affect the cutting quality and may even cause the material to melt or burn. Therefore, operators should choose appropriate tools according to the type, hardness and thickness of the specific processing material. The material selection of the tool is equally important. Carbide tools are usually suitable for harder metals, while high-speed steel tools are suitable for wood and plastic. In actual operation, regularly check the sharpness and wear of the tool, and replace the passivated tool in time to ensure the smooth progress of the cutting process. Only by choosing the right tool can the cutting quality of the CNC engraving machine be effectively improved, ensuring that the workpiece is cut through and meets the design requirements.

2. The cutting parameters of the CNC engraving machine are set unreasonably

The setting of cutting parameters is another important factor affecting the engraving quality. The parameters of the CNC engraving machine, such as cutting speed, feed rate and cutting depth, will have a direct impact on the cutting effect. If the settings are improper, it may result in incomplete cutting. For example, if the cutting speed is too fast, the time for the tool to slide on the material is reduced, and the cutting process may be incomplete, resulting in uneven cutting and even damage to the material. If the feed rate is set too low, the material may overheat, causing the cutting edge to melt and affecting the surface quality. In order to avoid such problems, it is recommended to conduct appropriate trial cutting before actual cutting to help find the best combination of cutting parameters. According to the nature and thickness of the material, the cutting speed and feed rate are gradually adjusted to ensure that each cutting process can achieve the best effect. In addition, by using the feedback system of the CNC engraving machine to monitor the cutting situation in real time, abnormalities can be discovered in time, and parameters can be adjusted quickly to ensure that the workpiece is cut through and the cutting effect is good.

3. The influence of the characteristics of CNC machine cutting materials

The physical and chemical properties of different materials play an important role in the cutting process. For example, some materials such as aluminum alloys, copper and other metals have high thermal conductivity, and it is difficult to dissipate heat quickly during cutting, which may cause the tool to overheat, thereby affecting the cutting depth and edge quality. In addition, the cutting effect of some composite materials or coated materials may also be affected by the interlayer structure, resulting in uneven cutting. Therefore, when selecting materials, it is crucial to understand their characteristics. For example, when CNC engraving and cutting machines cut wood, considering its texture and density, choosing a suitable cutting strategy can significantly improve the cutting effect. In addition, proper pretreatment can also significantly improve the cutting quality. For example, cleaning the surface of the material and removing dust, grease or oxide layers can avoid unnecessary interference during the cutting process. For materials that are more difficult to cut, a step-by-step cutting method rather than a one-time cut can effectively improve the success rate and ensure the quality of the final product.

By properly selecting tools, accurately setting cutting parameters, having a deep understanding of material characteristics and performing appropriate treatment, CNC machine operators can effectively avoid the phenomenon of not cutting through and improve processing quality and efficiency. At the same time, UTECH recommends regular evaluation and improvement of the operating process, continuous learning and mastering of new processing technologies to ensure competitiveness in the increasingly fierce market competition. Through these measures, you will be able to ensure that every workpiece processed by the CNC machine tool can achieve a high standard of cutting effect, improve overall production efficiency and customer satisfaction.
