Zirconia ceramic plunger with its excellent wear resistance, high temperature resistance, corrosion resistance and other characteristics, widely used in petroleum, chemical, food and other industries.

First of all, we need to understand the machining difficulties of zirconia ceramic plungers. The hardness of zirconia ceramics is extremely high, second only to diamond, which makes traditional metal cutting machining methods difficult to cope with. In addition, the brittleness of zirconia ceramics is large, which is easy to crack and damage. Therefore, in the machining process, how to ensure the machining quality and accuracy, while avoiding damage, has become the key to the machining of zirconia ceramic plunger.

Next, we introduce the finishing method of zirconia ceramic plunger. At present, the finishing process of zirconia ceramic plunger mainly adopts diamond grinding, grinding and polishing. First, the excess material on the surface of the zirconia ceramic plunger is removed by diamond grinding, so that it reaches a certain size and shape. Then, the surface quality and dimensional accuracy of the zirconia ceramic plunger were further improved by grinding process. Finally, the surface of the zirconia ceramic plunger is smooth as a mirror by polishing process.

In this process, the choice of abrasives and abrasives is crucial. Diamond abrasive is the most commonly used abrasive for machining zirconia ceramics, and its particle size, concentration and shape will affect the machining effect. In addition, parameters such as hardness, binder and shape of the abrasive tool also need to be adjusted according to the characteristics of zirconia ceramics. In short, only by finding the most suitable abrasives and abrasives can the machining of zirconia ceramic plungers become easier.

Machining method of zirconia ceramic plunger

1. Mechanical machining is divided into turning machining, grinding machining, drilling machining, grinding and polishing. Among them, grinding is the most commonly used. Diamond grinding wheel is generally used for grinding. Because the removal of cutting in grinding is a big problem. Therefore, the cooling working fluid is generally used, that is, the cutting powder can be washed. It can also reduce the grinding temperature and improve the quality of grinding ceramics.
2. Electrical machining: mainly through the discharge between electrodes to produce high temperature melting and gasification corrosion of materials.
3. Ultrasonic machining.
4. Laser machining.
5. Composite machining.

Machining precision: tolerance ± 0.001mm; coaxiality and roundness 0.002mm; surface finish RA0.025; Machining outer diameter of 0.2MM; or more length of 6000MM.

Of course, in addition to the choice of abrasives and abrasives, the setting of machining parameters is also the key to the finishing of zirconia ceramic plungers. For example, parameters such as grinding speed, grinding depth and grinding fluid can affect the quality and efficiency of the process. In the actual operation process, we need to adjust and optimize these parameters according to the characteristics of zirconia ceramics, in order to achieve the best machining effect.

Finally, we should also pay attention to the detection and protection of zirconia ceramic plungers. During the machining process, the size, shape and surface quality of the zirconia ceramic plunger should be regularly tested to ensure that it meets the requirements. At the same time, measures should be taken to prevent the zirconia ceramic plunger from being damaged during transportation and installation. Only in this way can the performance and life of zirconia ceramic plunger be guaranteed in practical applications.
