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.

The Magnesium Alloy Application In Bicycle Frame
The shock absorption effect of magnesium is 25 times that of aluminum, which makes bicycles better. It has good riding comfort; its high-temperature extrusion molding processability is good, and the thin-wall magnesium alloy pipe fittings are extruded, which significantly reduces the weight of the vehicle; the material is pollution-free, and the secondary recycling is simple. It is a green material.

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 near future.

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, aluminum alloy has good machinability, beautiful appearance, and light weight, and can play a very important role in driving control and environmental sustainability.

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 as an example. If the weight becomes lighter, the fuel efficiency and load capacity can be improved.
