Cemented carbide bar is a material with excellent wear resistance, high hardness and strength, which is commonly used in the manufacture of cutting tools, drills, milling cutters and other tools. Before application, it is usually necessary to grind and polish carbide rods to improve their surface quality and machinability. The following is the sharing of grinding and polishing process tips for carbide rods.

I. Grinding process skills

1. Select the appropriate grinding wheel: the grinding of cemented carbide rods usually uses diamond grinding wheels with metal bonding agent. According to different materials and requirements, choose the appropriate grinding wheel, such as grinding high-speed steel can choose ordinary diamond grinding wheel, grinding carbide can choose resin bond diamond grinding wheel.

2. Grinding wheel dressing: Before using, you need to check whether the grinding wheel is flat and has no damage, if there is any problem, you need to carry out dressing. The grinding wheel can be trimmed with a dressing wheel dresser to ensure the flatness of the grinding wheel and the smoothness of the dressing surface.

3. Grinding wheel installation: Install the selected grinding wheel on the grinding wheel table, and use the appropriate fixture to fix the grinding wheel to ensure stable installation. After installation, check whether the rotation is flexible and whether there is any loosening.

4. Use of coolant: It is necessary to maintain proper cooling during the grinding process, and coolant can be used for cooling to prevent the grinding wheel from overheating, resulting in dislodging of grits and deformation of the grinding wheel.

5. grinding wheel grinding: before grinding to determine the cutting speed and feed speed, try to choose the right speed to maintain the cutting effect and extend the life of the grinding wheel. Keep the workpiece stable during grinding and control the grinding force to avoid too much or too little force resulting in unsatisfactory grinding effect.

6. Cleaning of grinding wheel: After grinding the grinding wheel should be cleaned in time to remove the metal chips and sand particles on the surface of the grinding wheel to maintain the cleanliness and cutting performance of the grinding wheel.

Second, polishing process skills

1. Choose suitable polishing agent: according to the material and requirements of the carbide bar, choose suitable polishing agent. Commonly used polishing agents are titanium gold yellow, diamond polishing agent and so on.

2. choice of polishing cloth: choose suitable polishing cloth, choose different thicknesses of polishing cloth according to different polishing stages, in order to improve the polishing effect and efficiency.

3. polishing speed and pressure control: in the polishing process to control the polishing speed and pressure applied, too fast speed and too much pressure will lead to the polishing agent can not be fully effective, too slow speed and too little pressure will affect the effect of polishing.

4. The use of polishing liquid: adding the right amount of polishing liquid can improve the polishing effect, reduce the friction heat and wear, and prolong the service life of polishing cloth and workpiece.

5. Cleaning and maintenance of polishing cloth: After using for a period of time, the polishing cloth will accumulate polishing agent and impurities, which will affect the polishing effect. Therefore, the polishing cloth should be cleaned regularly to maintain its cleanliness and prolong its service life.

Summary: Grinding and polishing treatment of carbide bars is an important process to improve their surface quality and processing performance. The process techniques shared above can help us achieve efficient, stable and high-quality grinding and polishing treatment and improve the processing effect of carbide rods. In practical application, we should also explore and summarise the appropriate process parameters and operating techniques according to the specific situation, in order to meet the continuous improvement of workpiece quality and processing requirements.
