How to correctly choose a grinding wheel for tool grinding?

Product Applications / By

There are many types of grinding wheels and tools, with various shapes and sizes. Depending on the abrasive material, bonding agent, and manufacturing process, each grinding wheel has a specific range of applications. An incorrect choice can directly affect machining accuracy, surface roughness, and production efficiency. Therefore, when performing grinding operations, it is essential to select the appropriate grinding wheel based on the specific situation. How can we correctly choose a grinding wheel? Here’s a summary of commonly used grinding wheels in machining to help you make informed choices.

What are the diamond grinding (work) tools?

Product Applications / By

Diamond is one type of superhard material and cubic boron nitride is another. The two kinds of superhard materials after a series of machining and processing procedures can be made into a variety of tools and directly with them into a variety of functional devices, collectively referred to as superhard material products.

Several Methods for Achieving Mirror Finishing

Science Classroom / By

Mirror finishing refers to the process where the surface of a workpiece is polished to the point where it can reflect images like a mirror. This level of finish signifies exceptional surface quality, providing products not only with a high “aesthetic value” but also reducing notch effects, thereby extending the fatigue life of the workpiece. It holds significant importance in many assembly and sealing structures.

Diamond Synthesis Method — High Temperature and High Pressure

Diamond Knowledge / By

Currently, the world’s popular high-temperature and high-pressure diamond synthesizing equipment mainly consists of two-sided tops (belt, which is mainly popular in Europe and the United States), six-sided tops (unique to Mainland China), and splitting spheres (barssplitsphere, Russia) or modified splitting spheres (Gemesis Company). In 1954, before Christmas, the General Electric Company in the United States …
