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

Summer tire maintenance analysis

  According to the International Driving Safety Survey, the accident rate of driving in rainy weather is about 5 times higher than usual. In summer, there are many rainy weather, the road surface is wet and slippery, and the adhesion of tires is reduced, which puts a great test on automobile tires.
Tyre pressure is too high, don’t pour cold water
Regarding how to maintain tires in summer, experts pointed out that first of all, tires must be checked before driving. The tread depth of the tire used in the rainy season must not be less than 1.6 mm, preferably more than 3 mm, because the tread depth of the tire is too shallow, the drainage capacity of the tire will be reduced, resulting in a decline in wet grip, affecting the safety of driving, especially the rear tires There may be sideslip or tail flicking when turning.
Secondly, we must choose qualified tires and replace them regularly. There are many reasons for a puncture, and deterioration of tire performance is the culprit. No matter how durable a tire is, it cannot last a lifetime. When the tire gradually wears out, the steel wire layer gradually fatigues, and the tread is aging, its performance will inevitably weaken.
Third, always check the tire pressure, including the tire pressure of the spare tire. In the scorching summer, the tire is in contact with the hot ground. If the tire pressure is high, it is likely to cause a puncture. So don’t let the tire pressure be too high when driving in high temperature.
Fourth, if you find that the tire temperature and pressure are too high, you should stop in the shade to make the tire temperature and pressure drop naturally.
Challenge 2: Slippery road
Do not choose the expensive tires, just find the right ones
Tires are like the shoes of a car. For the sake of driving safety and comfort, it is of course impossible to wear the same pair of "shoes" all year round. Many car owners put on tires used on snow in winter. Now, for road conditions such as slippery roads, emergency curves and bumpy roads, more professional tires are available, which can effectively resist the dangers from the road. Easy to deal with rainy days!
“The safety function area of ​​Sanneng tires is characterized by its unique tread pattern elements. The continuous large-angle oblique cut pattern and wide longitudinal grooves can effectively discharge water from the tire area, thereby ensuring the tire’s grip on wet and slippery roads. And maneuverability." According to Goodyear safety experts, the control function area is composed of solid shoulder blocks and continuous ribs. This structure can provide a sensitive steering response for the vehicle. Even in an emergency corner or braking, you can get extraordinary stability and handling. The comfort zone of Sanneng tire is located in the rubber cushion of the inner layer of the tread, which contains a buffer layer in the multi-layer tread. Don’t underestimate this very thin buffer layer between the tread rubber and the steel wire belt. It can not only absorb the impact and improve the comfort, but also can effectively reduce the noise of the tire.
Challenge 3: Rugged road
Rugged roads to avoid tire damage
The Wenchuan earthquake affects the hearts of all Chinese people. If you drove to disaster relief, you must be very particular about driving the vehicle and choosing the tires. Good and skilled driving skills can effectively reduce tire wear, extend the service life of tires, and improve driving safety at the same time.
First of all, on poor roads, do not start too hard to avoid accelerated tread wear due to the drag of the tires and the ground; when the vehicle goes downhill, you should control the appropriate speed according to the length of the slope and the road conditions, so as to avoid Or use less emergency braking to reduce tire wear; vehicle turning should be based on the curve conditions and turning radius, generally slow down appropriately, so as not to accelerate unilateral tire wear due to inertial force and centrifugal force.
When driving on uneven roads, one must choose the road surface to reduce the collision between the tires and the road surface and avoid damage to the parts and tires. Second, slow down to avoid tire bumps and strong vibrations; when passing through muddy sections, choose a firmer and non-slip place to avoid tires sinking, idling on the spot, and severe vibrations causing serious cuts and scratches on the tires and sidewalls.
There are ways to use tires
When selecting and using tires, it should be carried out according to scientific methods, otherwise the service life of tires will be greatly reduced due to the influence of various factors. The notices are now announced as follows:
1. Tires should be far away from heat sources, power generation equipment and ozone-generating places.
2. Tires must not be too close to oils, combustibles and chemically corrosive products.
Air pressure:
1. The tires should be inflated according to the air pressure specified in the “Air Pressure Load Correspondence Table” specified in the national standard.
2. After the tires are inflated, check each part for air leaks. If any air leaks are found, they should be repaired in time.
3. The internal pressure of the tire must be normal during use. When running or working for a long time, check the tire pressure regularly.
4. When parking for a long time, the front and rear axles must be erected.
5. If the air pressure is too high, the tire is easy to wear crown and top burst; if the air pressure is too low, the tire is easy to deform and crush.
6. When twin tires are installed in parallel, the inflation of the two tires should be the same, not one with high air pressure and the other with low air pressure.
