Precautions for the pretreatment process of aluminum plate and aluminum alloy
Aluminum materials are extremely unstable in the air and easily form an oxide film that is difficult to identify with the naked eye. Due to the different processing methods of aluminum parts, such as casting, or directly cut from rolled sheets, or mechanically finely processed and formed, or formed by different processes and then heat treated or welded, the surface of the workpiece will appear Different conditions, different degrees of dirt or traces, for this reason, the pre-treatment process must be selected according to the actual situation of the workpiece surface in the pre-treatment process.

The Cleaning Steps Of Oxide Surface Treatment Aluminum Parts
The original physical appearance of aluminum cannot be restored after oxidation. Because the oxidation reaction that occurs is intermolecular, the metal bond interaction cannot be restored, and it can only be reduced and returned to the furnace.

The Advantages Of Industrial Aluminum Alloy Used As Heat Sink
The LED heat dissipation technology was born in 2000 and is made of semiconductor light-emitting diodes. The working principle is to generate electroluminescence by radiation compound. It is the most common way of heat dissipation. Aluminum heat sink fins are used as part of the shell to increase the heat dissipation area.

What are the advantages of 3D printing tools in the production of jigs and fixtures over traditional manufacturing methods?
In the automotive development process, engineers need a large number of customized production tools, which are often designed for specific tasks and models. Ford Focus's series production alone requires more than 50 different assembly tools. These tools are initially developed in pilot plants and then 3D printed on-site in all European plants.

How much do you know about the six skills of the laser cutting machine in the actual cutting process?
During the cutting process of the laser cutting machine, the beam is focused by the lens of the cutting head into a small focal point, so that the focal point can reach a high power density, and the cutting head is fixed on the z axis. At this time, the heat input by the beam far exceeds the part of the heat reflected, conducted or diffused by the material, and the material is quickly heated to the melting and vaporization temperature.

What are the effects of the temperature environment of the machining workshop on the machining of long parts?
The weather in Dalton, Georgia is hot, and Tuftco Corp. produces carpet tufting machines there. These machines have long rows of needles for gluing the carpet thread to the common base, posing special challenges for processing. When the company needed a more precise machine tool capable of handling extremely long horizontal strokes, the XiMill machining center from Bertsche Engineering Corp. emerged as the solution. However, even with new machines, extreme environments and part temperatures require further changes to the process.

The Operating Procedures Of Punch Press
Punch is a very common equipment in our lives, it is also what we often call stamping press. For the punch press, it is usually divided into three parts: the punch die, the lower die and the knife wall. The die on the punch is the upper half of the entire die, which is also a die mounted on the slider of the press. The upper die seat is the uppermost plate-shaped part of the upper die.
