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

The mechanical efficiency of the motor is equal to the actual output torque of its running state

 

The mechanical efficiency of the motor is equal to the ratio of the actual output torque to the theoretical torque in its operating state. The empirical formula for the mechanical efficiency of the variable motor is as follows: In the above formulas, is the laminar flow leakage coefficient, is the inlet and outlet pressure difference, is the oil dynamic viscosity, is the pump speed, is the motor speed, is the displacement ratio, is the laminar flow resistance coefficient , Is the mechanical resistance coefficient, is a certain torque loss that has nothing to do with the inlet and outlet pressure difference and speed, and is the full displacement of the pump. Obviously, it decreases with the increase of oil viscosity and speed, and increases with the increase of load pressure difference. The total efficiency of the closed hydraulic system increases with the increase of pressure; the total efficiency of the closed hydraulic system increases with the increase of the displacement ratio; with the increase of the displacement of the motor, the driving speed decreases, and the efficiency is obviously improved. The most severe working condition of the full hydraulic motor grader is a high-speed sports car. At this time, the efficiency of the closed system is low, and the system will generate a lot of heat. Whether the cooling system can meet the requirements of the sports car will directly affect the reliability and life of the hydraulic system. Closed system cooling calculation The closed system heat dissipation power loss power caused by the total efficiency of the closed pump and motor is the heat dissipation power required by the closed system.

When the efficiency of the closed system is low when the high-speed sports car is working, the theoretical formula for heat generation is inferred as follows, where is the flow of the system, is the heating power, and the heat balance of the closed system is calculated. The heat of the closed system is mainly fed into the system through the charge pump The cold oil replaces the hot oil and takes away. If the surface heat dissipation of the system components and the pipe loss are not taken into account, the heat absorbed per unit time when the cooling oil added to the system and the hot oil in the system reach a thermal balance is the heat dissipation power of the system. Assuming that the temperature difference between the cold oil added in the system and the hot oil in the system is (unit:), the heat absorbed by the cold oil added per second is the heat dissipation power of the system, namely: where:? Hydraulic oil density, take? The flow rate, the specific heat of the hydraulic oil, the difference between the oil temperature in the closed system and the oil tank temperature is proportional to the working pressure of the system. For a given closed system, its fuel supply and total efficiency are basically unchanged within the normal working range. Therefore, the difference between the oil temperature and the tank temperature in the system mainly depends on the working pressure of the system, that is, the load of the system.
