HT-M and HT-H are innovative diamond discs that extend to fine grinding of single micrometer particle sizes.They replace conventional grinding processes and provide excellent results in material grinding rate, surface quality, workpiece geometry and lifetime. HT diamond discs enable fine grinding of a variety of materials down to 3μm diamond grain size, providing a simple, clean and efficient fine grinding process.

High hardness and wear resistance
Diamond, as a known hard natural substance, endows grinding discs with high wear resistance, making them suitable for processing high hardness materials such as hard alloys, ceramics, and optical glass, and has a longer service life than traditional grinding tools.
High precision and low roughness
The surface roughness after processing can reach the nanometer level, meeting the stringent requirements for smoothness in semiconductors, optical components, and other applications.
High processing efficiency
High grinding efficiency, able to quickly remove materials, while reducing tool consumption and overall costs.
Strong stability
Uniform particle size, high consolidation strength, no jumping or scratches during processing, ensuring the flatness of the workpiece.
