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 development of lock-up clutches

With the continuous development of automatic transmission technology, only relying on simple hydraulic control or electrical control to engage or disengage the lock-up clutch has exposed many problems. Therefore, the American General Motors Company took the lead in adopting the electronic control of the lock-up clutch in 1891, and other automobile manufacturers soon followed. So far, it can be said that almost all hydraulic lock-up clutches have adopted electronic control.

For the electronically controlled lock-up clutch, the action of the lock-up piston is controlled by the lock-up solenoid valve and one or several sliding plunger valves. When the lock-up occurs or is released, the solenoid valve controls the sliding plunger. The oil pressure signal of the valve action, and the sliding plunger valve really controls the oil pressure that makes the clutch piston engage and disengage. Since the electronic control methods or methods of automatic transmission lock-up clutches of major automobile manufacturers have their own characteristics, a few representative ones are selected and introduced below.

Chrysler Automobile Company's lock-up clutch electronic control

Chrysler Automobiles adopted electronic control of the lock-up clutch in 1986. The hydraulic oil circuit part of the control system, and its lock-up solenoid valve is controlled by the electronic control unit through a lock-up clutch relay. As for the signal sources that the electronic control unit relies on to determine whether to lock or not, they are the cooling water temperature sensor, the vacuum sensor, the vehicle speed sensor, and the throttle closing switch. Normally, only when the engine cooling water temperature is higher than 6o6C, the vehicle speed is higher than 6k4m/h, and the engine intake manifold vacuum is about 26.66-66.66kPa, lock-up can occur. When the engine cooling water temperature indicated by the water temperature sensor rises above 66°C, the electronic control unit can determine whether to lock the lockup clutch in the torque converter according to the signals from the throttle closing switch, vehicle speed sensor and vacuum sensor .

Whenever the throttle closing switch is in the closed state, the electronic control unit will not energize the lock-up solenoid valve and therefore will not lock the clutch. There is no doubt that the function of this switch is to notify the electronic control unit to release the lock of the lock-up clutch. In order to reduce exhaust pollution and increase fuel economy when the throttle is closed and slowing down.

In order to prevent the lock-up solenoid valve from being energized and de-energized repeatedly during the brief opening and closing of the throttle valve, there is a part of the electronic control unit program to ensure that the engagement action of the lock-up clutch is delayed for a given period after the throttle closing switch is turned on. time.
