As we all know, grinding is the smoothing and precision machining of the surface of the part. The abrasive particles coated or pressed on the grinding tool are used to complete the processing through the relative movement of the grinding tool and the workpiece under a certain pressure. Some people think that grinding and polishing are the same, but grinding and polishing are two different processi...

The previous article introduced that grinding is the smoothing and precision machining of the surface of the parts. The abrasive particles coated or pressed on the grinding tool are used to complete the processing through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding and polishing are two different processing methods. Compared with polishing, the s...

It is well known that heat treatment is a common method for changing the mechanical properties of certain metals. Being able to change the hardness, toughness, and strength of a metal while keeping its chemical composition intact and nearly unchanged is a great way to tailor a metal to the needs of the environment and job. There are many different ways to heat treat metals, the most popular of whi...

The last article introduced what quenching is, and now let's share the application of quenching. The quenching process is widely used in the modern machinery manufacturing industry. Important parts in machinery, especially steel parts used in automobiles, airplanes, and rockets, are almost all quenched. In order to meet the various technical requirements of various parts, various quenching process...

One of the ways to restore a failed precision mechanical part is to use thermal spraying. First of all, the surface of the workpiece needs to be pretreated, and the degree of bonding between the coating and the base material (workpiece material) is the key. If the bonding cannot be performed or the bonding strength is not enough, the spray coating will be peeled off from the substrate, failing to ...

Electroless nickel plating technology is a method in which metal salts and reducing agents are used to obtain coatings by autocatalytic reactions on the surface of materials. So far, electroless nickel plating is one of the fastest growing surface treatment processes and has the widest range of applications. It can make the machined precision parts more wear-resistant and durable. The rapid develo...

The last article introduced what is electroless nickel plating, and this article will introduce the related process of nickel plating. Electroless nickel plating and electroplating nickel are both nickel plating processes, but they are very different. 1. The principle difference between electroless plating and electroplating is that electroplating requires additional current and anode, while elect...

Mirror polishing is a polishing process that makes the surface of the product show a mirror effect. It is mainly used to reduce the surface roughness of the workpiece. When selecting a polishing process for a metal workpiece, different methods can be selected according to different needs. This process is usually used in elevators. Cars, aerospace equipment accessories, molds, auto parts, medical m...
