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

A comprehensive strategy for car maintenance after long-distance driving

What items need to be maintained after long-distance driving? After long-distance trekking, especially after driving through bad road conditions, for those cars that are only suitable for urban roads, the loss of the car condition will be great. It is recommended that the owner send the car to the repair station for a comprehensive maintenance. After understanding the importance of maintenance, what maintenance items should be done?
Add oil and water
Check whether the oil and water of the whole vehicle are sufficient and whether the oil quality is good. The content includes engine oil, coolant, glass water, etc. If the liquid level is insufficient, add it, and replace the oil if it is of poor quality.
Prevent oil leakage
Check the powertrain and transmission system for oil leakage. The content mainly includes whether there is oil leakage in several major components (such as engine, gearbox, rear axle, etc.).
Reinforced chassis
Although the chassis of each car is anti-rust treatment before leaving the factory, and some even go through double-sided galvanizing or double-sided anti-rust treatment, from the perspective of professional and technical personnel, those domestic cars whose prices are less than 200,000 yuan If the chassis is only limited to driving on smooth urban roads, it will not be a big problem to check the chassis once 10,000 kilometers, but if you walk some mountain roads or rotten roads, then mud and other dirt can easily adhere to the chassis, even Some gravel that keeps hitting the chassis will also peel off the protective layer of the chassis, which increases the possibility of the chassis being rusted. Therefore, even if the vehicle only travels a few thousand kilometers, the chassis inspection is still necessary.
The inspection content includes whether each transmission component, suspension component is loose or damaged (such as transmission shaft, half shaft, half shaft dust cover, suspension, shock absorber, ball joint) and chassis corrosion inspection.
Tyre check hidden danger
The tire is the main part of the car in contact with the ground, so the risk of injury is also higher. The owner can check the tires for obvious injuries and scratches. If there are obvious scars on the sidewall, it is best to replace the tire, because the sidewall is thin and the pressure is limited, and the chance of a puncture will be greatly increased.
During maintenance, first check the tire pressure and wear condition, whether the nut is loose or fall off, and remove the embedded objects and iron nails between the twin tires or on the tread. If there is deviation or swing when driving, you need to perform four-wheel alignment or dynamic balance again.
Brake system
Including brake pads, brake tubing, brake master cylinder, sub-cylinder, hand brake, etc.
circuit inspection
Including whether the lights and instrument instructions are normal.
Clean the engine oil circuit
Some scenic spots are underdeveloped, and there may not necessarily be a high-grade gasoline supply. If you use low-grade gasoline or inferior gasoline, on the one hand, the engine will produce knocking and noise; on the other hand, it will easily cause the exhaust pipe catalyst, namely the three-way catalytic converter, to fail, resulting in unqualified exhaust emissions and sometimes blocking the exhaust pipe. , Due to poor exhaust, the engine will be weak and increase fuel consumption. Seriously, it will damage the internal parts of the engine, such as the top of the piston.
