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 .

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Precautions for the selection of oil and gas lubrication products for high-speed electric spindles

High-speed electric spindles are currently mainly used in high-speed engraving and milling machines and grinders. The reliable guarantee of high-speed operation of electric spindles and the choice of products are particularly critical. The current lubrication methods are divided into: grease, oil mist, and oil and gas. Grease-lubricated electric spindles are not high in speed, and all bearings are packaged when they are selected. For high-load electric spindles, this lubrication method is both advantageous, and the advantage is that the investment cost of electric spindles is low. Oil mist lubrication: In fact, when the electric spindle is designed with only one lubrication inlet, this lubrication method is not conducive to the reliable and effective supply of lubrication, excessive consumption of oil and the risk of pollution to the operating environment. The economic cost is not good. Oil-air lubrication: Due to the obvious advantages of oil-air lubrication, current electric spindle design manufacturers generally adopt it. Let me talk about the requirements for oil and gas lubrication of electric spindles: 1. Lubricant cleanliness grade: 13/10 (ISO4406);

2. Air cleanliness: the air filtration accuracy is 0.01 micron;

3. Air dryness: dew point is +2℃;

4. The inlet gauge pressure in front of the bearing nozzle: 2-3bar;

5. Oil and gas pipeline: the inner diameter is 2 to 2.5mm, and the transparent pipeline with small bending radius is not easy to bend;

6. The length of the oil and gas pipeline: the ideal length is 1 to 4 meters. The spiral pipe at the distance from the terminal lubrication point is conducive to oil storage. When the bearing stops and runs again, it is helpful for the oil and gas to be in place quickly and shorten the response time. So when choosing oil and gas lubrication products, you must first meet the above requirements. In addition, the performance of oil and gas lubrication products can achieve good oil and gas transmission to the electric spindle and achieve reliable and stable operation.

1. Precisely quantified oil, and the amount of oil delivered to each lubrication of the bearing end can be adjusted arbitrarily, ranging from 5-40mm3.

2. Digital display time setting: It can realize the arbitrary setting of the oil supply cycle time.

3. Pressure monitoring: It can monitor the oil and gas delivery pressure or the gas source pressure, with priority to monitor the oil and gas pressure.

4. Oil supply status monitoring: As the amount of oil supplied per unit time of the electric spindle is small, and the interval of oil supply is 3min-7min, or even longer, the stability test of each lubrication point each time is an important indicator.

5. Bearing cavity pressure: the oil and gas pressure should be adjustable and set.

6. Display and fault feedback: The operating status of the product and the faults that appear have local display and remote feedback functions, such as: high or low air pressure failure, low liquid level, oil supply failure, etc. The above points are the guarantee to ensure the stable and reliable operation of the electric spindle. Therefore, it is necessary to carefully select suitable products when selecting oil-air lubrication. <br />
