What are the advantages of CNC machining of radiator parts?

by
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

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

Spring Design Attention And Roll Forming Method

by
Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Obviously effective high-speed bearing oil-air lubrication

cncmachining December 25, 2021

Bearings are widely used components in mechanical equipment, roughly divided into sliding bearings and rolling bearings, and their main function is to support shaft parts. Electric spindle bearings are mostly rolling bearings. During use, they need to be equipped with proper lubrication methods to make them fully effective.

…
The heating of the electric spindle bearing will affect the machining accuracy and machining efficiency. The electric spindle uses a built-in motor, and the heat dissipation effect is relatively poor. This requires dedicated cooling channels to dissipate heat. The heat comes from two sources: the built-in motor generates heat from rotation and the bearing friction generates heat. The use of oil-air lubrication can eliminate the impact of these two problems. Oil-air lubrication is a gas-liquid two-phase flow. On the one hand, compressed air can take away the heat generated by the rotation of the built-in motor and bearing friction; on the other hand, after the lubricating oil is delivered to the lubrication point, it provides uniform lubrication.

The viscosity of the lubricating oil also affects the temperature: at the same speed, the increase in the viscosity of the lubricating oil will increase the bearing temperature. Lubricants with different viscosities have different changes in bearing temperature. The temperature rise of high viscosity will be greater than that of low viscosity, and with the increase of spindle speed, the trend of temperature rise will become more and more obvious. In actual use, the oil consumption of bearing oil-air lubrication is very small, and only the amount of oil actually needed for bearing operation is needed.

For more questions about the oil and gas lubrication of the electric spindle, please consult Doppy directly.
