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

What are the selection of positioning datums for precision parts processing?

 The production of nuts, studs, and stainless steel materials is becoming more and more intelligent now. When producing these equipment accessories, choose accurate and high-standard equipment. With the advancement of science and technology, intelligent and automated instruments , The equipment has a very fast speed in the circulation of various fields, which brings challenges and opportunities in a new stage to the development of precision parts. This paper analyzes the market demand and process concept of precision parts, and combines the skills and problems in actual processing (with the scope of clamp work as the limit), and explores the solutions and skills of related problems in precision parts processing in order to improve precision parts. Improve the quality of market supply and demand, and promote the development of a technological and intelligent society.


In actual production, the structure of each part may be very different, which also greatly increases the difficulty of processing. However, if you observe carefully, you can find that the basic geometric composition of parts is nothing more than outer circle, inner hole, plane, thread, tooth surface, curved surface, etc., so as long as the processing of these shapes is mastered, the difficulty of precision parts processing is also Can be greatly reduced.

In the process of precision parts processing, whether the selection of positioning reference is reasonable or not determines the quality of the parts, and it is very important to ensure the dimensional accuracy and mutual position accuracy of the parts, as well as the arrangement of the processing sequence between the surfaces of the parts. Big impact. If the fixture is used to install the workpiece, the choice of positioning datum will also affect the complexity of the fixture structure. Therefore, the choice of positioning datum is a very important process problem in precision parts processing.

Nowadays, mechanized and automated production has been achieved in part of the production process. Then the automated processing system can automatically monitor its operating status, and automatically adjust its parameters when subjected to external interference or internal excitation to achieve the best state and availability. Self-organization ability, so as to greatly improve the efficiency of rough and finishing processing under the premise of ensuring processing accuracy.
