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 .

Exploration of high-speed bearing lubrication methods

Effectively controlling the temperature rise of the high-speed rotating electric spindle bearing is a very important indicator of the electric spindle, and the temperature rise of the spindle is closely related to the bearing.The method to reduce the temperature rise of the bearing is: (1) reduce the dynamic friction of the bearing; (2) adjust and improve the heat dissipation environment of the bearing.Commonly used electric spindle lubrication has the following methods:

1.Grease lubrication


Under normal circumstances, the calorific value per unit time of the bearing increases as the temperature rises, and the viscosity of the lubricating oil will decrease accordingly. In order to avoid overheating and injury of the bearing, it is necessary to fully add lubricating oil. However, the increase in oil volume also increases the resistance of stirring and increases the dynamic friction loss, thereby increasing the resistance of the electric spindle. If a small amount of grease is used for lubrication, not only will it not achieve the purpose of low friction, it will also not bring out the heat of the bearing. The high-speed rotation of the high-speed electric spindle accelerates the deterioration of the grease and reduces the service life of the grease.

2.Oil mist lubrication


At present, the lubrication of the electric spindle in the high-speed grinding of the CNC grinder mostly adopts oil mist micro-lubrication. Oil mist lubrication is the micro-lubrication, which reduces the friction loss and also reduces the temperature of the bearing and increases the service life of the electric spindle. Another advantage is that due to the oil mist lubrication of the electric spindle, the inside of the bearing seat has a certain air pressure, which avoids the damage of the electric spindle caused by the abrasive particles entering the shaft shell of the electric spindle. However, oil mist lubrication has environmental pollution and no problems with oil control.

3.Oil-air lubrication

Oil-air lubrication has the following characteristics:

(1) A very small amount of lubricating oil can be continuously and stably supplied to the bearing;

(2) Less environmental pollution. After placing the oil-air-lubricated electric spindle in a propylene box for about 2 hours, the air pollution level in the measuring box is about 0 mg/m. Pollution is less than that of oil mist lubrication . The reason is that oil-air lubrication has less oil than oil mist lubrication, and the lubricating oil and compressed air flow into the bearing in two phases.

(3) It is difficult for dust or moisture and cutting fluid to enter the bearing of the electric spindle. The compressed air keeps the positive pressure inside the bearing of the electric spindle.
