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...

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...

We introduced what is vacuum heat treatment in the last batch of articles, and now let's introduce the characteristics of vacuum heat treatment. The vacuum state is an excellent protective environment. The mechanical parts after heat treatment in the vacuum environment are smooth and bright in appearance, the internal structure has been changed, and the mechanical properties are excellent. Its cha...
