2. Grinding machines and tools

Grinding machines (grinders) use grinding tools to perform surface treatment on workpieces. Most grinders utilize high-speed rotating grinding wheels, with some using other abrasives and free grinding materials like honing machines, superfinishing machines, belt grinders, lapping machines, and polishing machines.

Types of grinding machines:

  • Cylindrical grinders: For grinding cylindrical and conical external surfaces.
  • Internal grinders: For grinding cylindrical and conical internal surfaces.
  • Coordinate grinders: Precision internal grinders with coordinate positioning devices.
  • Centerless grinders: For grinding cylindrical surfaces, using centerless holding methods.
  • Surface grinders: Mainly for grinding flat surfaces.
  • Belt grinders, honing machines, and more: Specialized for various grinding operations.

The evolution of grinding machines is closely linked with the increasing number of high-precision, high-hardness mechanical parts, and the advancement of precision casting and forging technologies.

3. Silicon carbide grinding tools

Silicon carbide grinding wheels, made from a mixture of carbon and silicon heated together, exhibit high hardness and excellent wear resistance, making them suitable for grinding stainless steel and other hard materials.

Applications of silicon carbide wheels:

  • Hard metals: Efficient in removing burrs and maintaining accuracy for hard metal surfaces.
  • Optical glass and gems: Effective for high-efficiency, fine grinding with minimal damage.
  • Various metals: Achieves satisfactory grinding results for stainless steel, cast iron, steel, brass, and copper.
  • Other materials: Suitable for grinding marble, tile, rock, sandstone, quartz, granite, diamond, and more.

In conclusion, silicon carbide wheels are versatile, handling a wide range of materials from hard metals to glass, ceramics, and various metals and non-metals, providing satisfactory grinding results with their efficient abrasive capabilities.
