How to measure the surface roughness of large parts?

Large parts, such as the engine block of emergency generators, construction machinery or ship engines; truck steering knuckles; or gears and bearings used in wind generators are usually too large and heavy to be performed on fixed roughness measurement equipment Measurement. Nevertheless, the roughness parameters must still be tested. In fact, roughness measurements on large […]

How to avoid bubbles or holes in the 3D printing manufacturing process?

Laser powder bed fusion is the dominant additive manufacturing technology and has not yet reached its potential. The problem facing the industry is that sometimes tiny bubbles or holes are formed during the printing process, and these holes form weak points in the final product. In the 3D printing process of parts, when the low-speed […]

How to choose the best grinding process for 3D printed parts

For metal production parts manufactured by additive manufacturing (AM), post-processing is usually required, especially on functional surfaces. Abrasive machining including grinding and polishing has the ability to finish machining conventional parts and additive parts (ie, 3D printed parts).  Compared with mechanical processing (such as milling and other alternative finishing processes), grinding has the advantage of […]

Why Is Anodic Oxidation "Favored" In Aluminum Parts Surface Treatment?

We all know that aluminum is widely used in life and industry, and there are many kinds of surface treatment methods for aluminum. There are usually anodizing treatment, chemical conversion treatment, micro-arc oxidation treatment, electroplating treatment, electroless plating treatment or surface organic coating (spraying). Powder or spray paint) and so on. And the most widely […]

Several 3D printing cutting-edge technology breakthroughs that shocked the world

3D printing (3DP) is a kind of rapid prototyping technology. It is a technology that uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer based on digital model files. Today, we are here to enumerate the most “tall” major advancements in the global 3D printing industry in […]

The aluminum material that is touted as sweet and delicious may not be so "pure"

When it comes to aluminum, PTJ can’t help but think of the motto of Lotus founder Colin Chapman. If you want to make your car faster and easier to handle, “simplify the structure, and then reduce the weight”, there is no doubt that aluminum is like this. Kind of material. As an automotive machining material, […]

Four Ways To Achieve Lightweight 3D Printing

The advantages of lightweight structure are not difficult to understand. Taking a car as an example, lighter weight can bring better handling, and the power output by the engine can produce higher acceleration. Because the vehicle is light, the acceleration performance is better when starting, and the braking distance when braking is shorter. Take airplanes […]
