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

The production process of KOVAR parts processing has a great relationship with the process, including the process environment elements and the optimization configuration elements of the process route. The process route process needs to be formulated by an experienced person. The following is a brief explanation of the process process.

The formulation of the process route process: First, the geometric structure of the parts, the core parts of the accuracy index, the accuracy requirements, material characteristics, heat treatment requirements and performance requirements, etc. should be carefully analyzed, and then the blanks of the parts should be reasonably selected, the cnc machining china equipment should be used reasonably, and reasonable measures should be taken. Many process links such as stress process measures are reasonably configured. In the production organization process, the process is strictly implemented. During the process, strict inspection is performed. For general precision parts, the process route is: rough machining-aging-semi-finishing -Finishing can be done. Facing the processing of precision mechanical parts, such a processing route is obviously not enough. The processing route must be lengthened, and aging treatment must be properly interspersed, and super-finishing procedures are configured to ensure the processing requirements.

The usual process flow is: primary roughing-primary thermal aging-secondary roughing-secondary thermal aging (or vibration aging)-semi-finishing-vibration aging is enough-finishing-natural aging (or low temperature stability treatment)-precision Processing. Among them, the heat treatment requirements of precision parts should be arranged according to the different requirements of the overall hardness, partial hardness, and surface hardness of the parts. The stable processing of the precision mechanical parts processing accuracy is also very critical and complex, simple one or two. This method has been unable to meet the requirements, and usually adopts a variety of methods according to needs, such as stress annealing, low temperature stabilization, vibration aging, natural aging, and even cold treatment to achieve the accuracy and stability requirements of precision parts.

In order to ensure the machining accuracy, roughing and finishing are best performed separately. Because of the large amount of cutting during rough metal machining, the workpiece is subjected to large cutting force, clamping force, heat generation, and the machined surface has a significant work hardening phenomenon, there is a large internal stress inside the workpiece, if rough or rough machining Continuously, the precision of the parts after finishing will be quickly lost due to the redistribution of stress. For some parts that require high machining accuracy. After rough machining and before finishing, low temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.
