Tungsten carbide internal grinding is the most common processing method for tungsten carbide parts and components, It can be seen everywhere in cemented carbide production and processing plants. Because of its frequent use, improper use which leads to many problems such as edge loss, cracks, and size deviations, Zhuzhou Chuangrui Cemented Carbide Co., Ltd sorted out the following relevant characteristics and precautions for cemented carbide internal grinding processing for you to learn how to reduce the generation of waste.The main characteristics as below:
1, When grinding the inner diameter of the bearing ring, the instrument is used to measure the grinding, and when the outer ring raceway of the roller bearing is grinded, the dimensional accuracy is reduced, and the fixed-range grinding is selected.
2, Internal grinding has two measurement methods to control dimensional accuracy: fixed range and inductive instrument measurement, which can be pre-selected.
3, The separation of the hydraulic oil tank from the bed reduces the thermal deformation of the internal grinding and improves the working accuracy of the internal grinding process.
4, The reciprocating system of the internal grinding table and the feeding system of the bedside box are all made of precise preloadable and rigid cross roller guides, which have low friction resistance, stable operation, high frequency, long life and compact structure.
Cemented carbide internal grinding processing is one of the main businesses of Zhuzhou Chuangrui Cemented Carbide Co., Ltd., we have more than 15 years experience in cemented carbide grinding process,and we accumulated certain process precautions in the production process as follows:
1, There are two common measurement methods for internal grinding processing: range measurement and inductance instrument measurement, the specific use should be pre-selected according to the required environment and object.
2, The hydraulic oil tank during internal grinding needs to be separated from the bed, which can minimize the thermal deformation during machining and it also can improve the accuracy of internal grinding processing.
3, The reciprocating system and the feed system of the headboard box in the table of tungsten carbide internal grinding both adopt sufficiently rigid cross roller guides, which can reduce the friction resistance coefficient and maintain the smooth operation while ensuring a compact structure with high frequency and long life.
4, The grinding of the bore diameter in the internal grinding process is carried out by using the outer circle as the positioning standard, the unipolar electromagnetic centerless fixture is adopted, and the floating of multi-point contact is used to achieve the supporting effect, so that the grinding process of the workpiece is stable and easy to adjust.
The cemented carbide grinding action must be controlled separately by multiple solenoid valves, so that when in the state of manual adjustment, each action can realize the unilateral controllable form, and cemented carbide grinding processing has a hand-cranked mechanism, which can make the elimination and adjustment of hydraulic fault relatively simple and convenient.
