Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone middle frame processing, and in particular to a CNC processing mechanism for a mobile phone middle frame. Background Art

[0002] The mobile phone middle frame is an important component of the mobile phone shell. It is usually a frame structure that connects the various components of the mobile phone together and provides support and protection for these components. The mobile phone middle frame is usually made of materials such as metal or plastic. It is needed in the production process of the mobile phone middle frame. The mobile phone middle frame CNC processing mechanism can perform precision processing through computer-controlled tool paths and operations, and can achieve efficient, accurate and repeatable processing. The mobile phone middle frame CNC processing mechanism can achieve high-precision and high-efficiency processing of the mobile phone middle frame, while ensuring the quality and consistency of the product.

[0003] When the existing mobile phone middle frame CNC processing mechanism is processing the mobile phone middle frame, a large amount of heat will be generated on the mobile phone middle frame when the cutting blade is cutting. The existing mobile phone middle frame CNC processing mechanism usually only has the function of cooling the cutting component, and cannot cool the mobile phone middle frame after cutting in time, which will cause the mobile phone middle frame to overheat, thereby affecting the mechanical performance and life. During polishing and grinding, a large amount of dust and debris will be generated. The accumulation of dust and debris will increase the friction during the processing, affecting the processing quality and precision. The dust and debris will enter the interior of the mechanical parts, causing wear and damage to the parts, reducing the life of the equipment, and long-term accumulation of dust and debris may affect the stability and operation efficiency of the equipment, and increase the probability of failure.
