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

Performance analysis of sand cores for automobile castings

The assembly of sand cores for complex auto parts is done manually on the assembly line supported by the roller table. Since the binders used in large quantities are materials such as paper pulp waste liquid and compound grease, the price is cheap, the core sand is easy to mix, and the performance of the sand core basically meets the needs of mass production of automobile castings. This was very advanced in the 1950s. However, the sand core must be dried, which undoubtedly increases energy consumption. Cast iron smelting Gray cast iron smelting uses 4 cold-air cupolas with a melting rate of 3t/h, which are divided into two groups of alternating furnaces, and form a double smelting system with an electric arc furnace with a capacity of 3t. The produced molten iron is poured into castings such as cylinder blocks, cylinder heads, gearbox housings, clutch housings and brake drums.

malleable cast iron smelting adopts two cold-air cupolas with different melting rates, and is equipped with two electric arc furnaces with a capacity of 5t to adjust the chemical composition of molten iron, and mainly produces malleable iron parts for the chassis. The sand processing system is centrally arranged in the sand processing department of the workshop. It uses 6 advanced Soviet-made balance wheel sand mixers at that time to supply molding sand for each of the gray cast iron and malleable cast iron molding production lines. General castings are made of single sand; important castings such as the cylinder block and rear axle housing are made of surface sand and back sand.

The mixed molding sand is uniformly modified by the intermediate storage and mixing hopper, and then sent to the sand hopper above the molding machine by a belt conveyor. The old sand after falling sand is transported by a belt conveyor, crushed by a drum screen, sieved, electromagnetic separation drum, etc. to remove the scrap metal in the sand, and then sent to the old sand bucket for reuse. After the clay and coal powder are crushed into powder by the ball mill dry method, they are sent to the hopper above the sand mixer and added to the sand mixer through a quantitative system; after the new sand is dried by the horizontal drying drum, it is sent into the new sand by the belt conveyor In the hopper.
