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

Extended hob life benefited from micro lubrication machining

Micro-lubrication quasi-dry machining is a new type of machining method that replaces traditional cutting fluid with micro-lubrication and has been applied in some enterprises. Under quasi-dry cutting conditions, the cutting process, machine tool design, micro-lubrication device, lubricant, operation and cutting tools are different from traditional wet cutting. The theoretical basis of quasi-dry cutting is far less mature than traditional cutting fluid metal cutting theory. The processing technology of dry cutting needs to be explored and accumulated based on the workpiece material, the selection of tools and the coating, so that the technical characteristics of quasi-dry processing can be brought into play.
The working principle of Doppelio’s built-in micro-lubrication device is to generate micron-level suspended oil particles through a precision built-in oil mist generator powered by air. Spindle) is transported to the cutting area between the tool and the workpiece almost without loss, or sprayed to the cutting area through pipelines and external nozzles to participate in cutting lubrication.
In gear machining, three nozzles are usually required to spray micron oil mist particles into the cutting area. One nozzle keeps a certain distance and sprays the rake face of the hob. The other two nozzles are arranged on the left and right of the hob blade, the hob blade and the workpiece. The oil film between the contact points improves the friction between the hob blade and the workpiece material, inhibits temperature rise, and at the same time improves the quality of the machined surface, and has the effect of preventing the machined surface from rusting, and the life of the hob is prolonged.
In addition to the damage caused by impurities in the workpiece material, the life of the hob is mainly the damage to the hob and the coating caused by the repeated heating and cooling of the hob during cutting fluid processing. Hot brittleness”. During micro-lubrication quasi-dry machining, ultra-fine oil mist particles are conducive to penetrating into the cutting area to form an oil film (pressureless cutting fluid may not effectively penetrate into the cutting area), reducing “hob-workpiece” and “hob-cutting” The friction between them plays the role of restraining temperature rise, reducing hob wear, preventing adhesion and improving the quality of workpiece surface and hob life.
