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

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

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℃.   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 .

Analysis of Lubricant Used in Rolling Bearings

As we all know, bearing is a pivotal component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission of the equipment. Therefore, it is particularly important to choose a suitable lubricant. So, how should the rolling bearing lubricant be selected, and what are the methods?

The lubricants used in rolling bearings are divided into two types: grease and lubricating oil.

One, grease.

Grease is made by mixing lubricating oil, thickener and additives at high temperature. According to the type of thickener, grease can be divided into calcium-based grease, sodium-based grease, calcium-sodium-based grease, lithium-based grease, aluminum-based grease, and molybdenum disulfide grease.

The main performance indicators of grease are penetration, dropping point, mechanical stability, oxidation stability and corrosion resistance. The choice of grease should be based on the working conditions, temperature and load of the bearing.

Dropping point is generally used to evaluate the high-temperature performance of grease. The actual working temperature of the bearing should be 10-20℃ lower than the dripping point of the grease, and the use temperature of synthetic grease should be lower than 20-30℃. Penetration refers to the hardness or bearing capacity of the grease. Bearings that work under heavy loads should use grease with low penetration. Calcium-based grease is not easy to dissolve in water and is suitable for working environments with humid and high water content. Sodium-based grease is easily soluble in water and is suitable for dry and low-moisture working environments.

Generally, grease is often used in bearings. The advantages of lubricating grease are: high oil film strength; good grease adhesion, not easy to lose, and long use time; simple sealing, which can prevent dust, moisture and other debris from entering the bearing. The disadvantage is: when the speed is higher, the friction loss power is larger.

Insufficient or excessive grease will cause the temperature rise and wear of the bearing to increase during the operation of the bearing, so the filling amount of grease should be moderate. Generally, it is appropriate to fill 1/3 to 1/2 of the space between the bearing and the housing.

Two, lubricants.

lubricants include special mineral oil, vegetable oil and synthetic lubricants.

The performance indicators of lubricating oil include viscosity, viscosity-temperature characteristics, acid value, corrosiveness, flash point, freezing point, etc.

Viscosity: Refers to the frictional resistance of the relative movement of the lubricating oil. The viscosity directly affects the fluidity of the lubricating oil and the ability to form a lubricating oil film between the friction surfaces. Therefore, viscosity is an important basis for choosing lubricating oil.

Bearings working under high speed or high temperature conditions are generally lubricated by oil. The advantages of oil lubrication are: reliable lubrication, low friction coefficient, good cooling and cleaning effects, and a variety of lubrication methods can be used to adapt to different working conditions. The disadvantage is that it requires complicated sealing devices and oil supply equipment.

When the bearing is immersed in oil (oil valley lubrication), the height of the oil level should not exceed the center of the rolling element under *. When the speed is high, drip oil or oil mist lubrication should be used.
