What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

Automobile automatic transmissions require more careful care and maintenance

The traffic conditions in the city are getting worse and worse. Stop-and-go in traffic jams is exhausting for owners of manual-shift cars. Therefore, the light and trouble-saving automatic transmission car has almost become the first dazzle of most urban residents. Although the automatic transmission car is easy to use, but because the automatic transmission system is a very sophisticated assembly, especially the manual automatic transmission Its structure is even more complicated. Therefore, once the automatic transmission fails, it is very troublesome and expensive to repair. In view of this, automatic gearboxes need more careful care and maintenance.

Regularly check the transmission oil

A kind of lubricating oil called ATF is injected into the automatic gearbox. In addition to lubricating and cooling down, its role is to transmit the power between the engine and the gearbox. The working temperature of ATF oil is generally around 120 degrees Celsius, so the quality of the oil is very high, and it must be kept clean.

Always check whether the automatic transmission oil level is normal. The inspection method of automatic transmission oil is different from that of engine oil. The engine oil is checked in a cold state, and the transmission oil needs to be preheated to about 50°C, and then the gear lever stays in each gear for 2 seconds. Put it in the parking block. At this time, the normal oil level of the oil dipstick should be between the highest and lowest lines. If it is not enough, add oil of the same quality in time.

In general, whether it is a manual gearbox or an automatic gearbox, it is recommended to change the automatic transmission oil every 12 months or 20,000 kilometers. Some models have instructions for 24 months or 40,000 kilometers. However, the above is only a general recommendation. Due to the special conditions of Beijing’s vehicles, heavy sandy weather, road congestion, and poor air quality, it is recommended that vehicles should be inspected regularly and replaced with ATF in time.

Change the gearbox oil correctly

Generally, when replacing the automatic transmission oil, the screw in the oil bottom of the automatic transmission is usually removed to leak the old oil and then add new oil, but this can only replace about 30% of the new oil and 70% of the old oil. Still remaining in the gearbox. If the oil is changed by removing the oil pan, the oil change rate can reach 70%, which can actually ensure the health of the gearbox. However, the current better method of oil change is dynamic oil change. Special gearbox cleaning equipment is used. During the operation of the gearbox, the old oil is fully circulated and drained before adding new gearbox oil to change the oil. The rate is as high as 90%.

GM, Toyota, Ford and other brands of automatic transmissions have different friction coefficients, so ATF oils are different and cannot be mixed. Mixed use of ATF will cause damage to the friction lining of the gearbox, slipping of the clutch and brake, etc., and in severe cases, the friction lining will be destroyed.
