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

Introduction to 5 key points of car maintenance

  Measure tire pressure

The tire measures every inch of the journey with its own body, which is extremely hard.Therefore, the tire pressure should be measured first to maintain the same tire pressure for all four wheels.If the tire pressure of a certain tire is abnormally low, carefully observe whether the tire is punctured, and repair it in time.If the wound is too large or the wound appears on the wall of the fetus, it can only be asked to retire.

There is also the problem of tire dynamic balance.The rough road in the wild may affect the dynamic balance of the tires. The originally smooth car suddenly seems to lose its temper, with abnormal tremors, which indicates that the dynamic balance of the tires has failed.The reason may be the deformation of the wheel hub, tire wear, or it may be that the balance weight clamped on the wheel hub was shaken off during a strong bump. Therefore, it is extremely necessary to rebalance each tire.

Oil change

During a self-driving trip, high-load operation will make the engine stand the test, so check the engine oil and water tank water.If it is an automatic transmission car, also check whether the transmission oil is missing, and if it is excessively consumed, it should be refilled in time.

If the self-driving trip is relatively long, it is best to change the engine oil, because the engine’s high temperature work for several days may cause the engine oil to deteriorate.And whether the engine belt is loose also needs attention.In addition, the dust during the journey may make the engine body, engine radiator and air-conditioning radiator covered with mud, which affects the engine’s heat dissipation and air-conditioning work. At this time, you need to go to a professional car dealer and use a special cleaning agent to treat the engine and radiator. Carry out special cleaning.

Do 4-wheel alignment

The bumpy road brings continuous impact to the chassis, and the four-wheel positioning of the vehicle may also be changed as a result, resulting in abnormal tire wear.Therefore, after returning from the journey, the chassis of the vehicle should also be checked, and if necessary, the four-wheel alignment should be done again for the car.Similarly, severe vibration can damage the steering system, and you should observe whether the steering gear ball head is loose.In addition, the screws of the chassis part should be tightened.

Check the brake system

The brake system is also an inspection link that cannot be ignored. Frequent braking and gravel-filled environments during the journey will severely wear the brakes.If the brakes are excessively worn, or there is a “hissing” noise when you step on the brakes, then the brakes need to be checked.

Clean the engine oil circuit

There are certain differences in the quality of oil in various regions, and even some of the oil quality is unqualified. Adding such oil will cause great damage to the engine and the oil circuit.If you use inferior gasoline, on the one hand, the engine will produce knocking and noise; on the other hand, it is easy to make the three-way catalytic converter fail. At this time, the engine will often be weak and fuel consumption will increase, which will seriously damage the internal parts of the engine.If the above situation occurs, it is best to go to the after-sales service station to drain the oil, and then add some additives to clean the oil circuit for maintenance.
