What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Precision CNC machining manufacturers explain how CNC CNC lathes are processed

According to the introduction of precision CNC machining manufacturers, the large-scale CNC machining parts are made of bar materials, and the process plan of rough machining and finishing is adopted. The specific process flow is as follows: blank → rough turning → rough milling → aging → fine turning → fine milling.

 

CNC lathe is a kind of high-precision and high-efficiency automatic machine tool. The use of CNC lathe can improve processing efficiency and create more value. The emergence of CNC lathe has made enterprises get rid of the backward processing technology. The processing technology of the lathe is similar, and the processing technology of the CNC machine tool has the characteristics that other machine tools cannot match.

 

Rough milling: According to the analysis of precision ODM processing manufacturers, a margin of 1.5mm is reserved on the side and bottom of the cavity, and the process hole is pre-drilled at the hole position of φ12mm. Aging: Removal of material and processing stress. Finish turning: Finish turning the end face, the outer circle and boring the process hole φ6mm. It is required to complete the clamping in one time to ensure the coaxiality and lay a good foundation for the subsequent processing. Precision milling: to ensure the final requirements of the parts, is the focus of this article.

 

①Rough milling cavity rough machining mainly removes large margins and lays a good foundation for subsequent finishing. Therefore, when machining the cavity, choose a low-cost common digital control CNC machining milling machine. This process requires that the inner contour is machined according to the shown part structure drawing, the arc corner is R5mm, and the remaining finishing allowance is uniform, which is 1.5mm. And this process also needs to pre-process the positioning holes required for finishing at the φ12mm hole position.

 

②The high-speed machining technology of precision milling cavity is a manufacturing technology that has been applied in recent years. In high-speed cutting processing, due to the small cutting force, the machining deformation of the parts can be reduced, which is more suitable for thin-walled parts, and the chips are removed in a short time, most of the laser cutting heat is taken away by the chips, and the workpiece is thermally deformed Small, it helps to ensure the accuracy of the size and shape of the parts; high-speed machining can obtain higher surface quality, and the machining cycle is greatly shortened. Therefore, in combination with the characteristics of this type of thin-walled disc parts, high-speed machining is selected when finishing the cavity.

 

③Introduced by the precision CNC aluminum machining manufacturer, the positioning hole is processed by the center hole φ6mm and φ12mm hole as the positioning hole for the finishing of the part, so it must be machined in place before finishing the cavity.
