Read MoreAbrasive tools are cutting tools primarily made of abrasives (such as diamond, CBN, and corundum). They are widely used for precision grinding, polishing, and deburring of materials such as metals, ceramics, and glass. They achieve high-precision surface treatment on workpieces through the micro-cutting action of abrasive particles, making them an indispensable and critical tool in modern manufacturing.
Main Categories of Abrasive Tools
By Abrasive Type:
Superabrasive Tools: Diamond (for cemented carbide and ceramics), Cubic Boron Nitride (CBN) (for hardened steel and high-temperature alloys)
Conventional Abrasive Tools: Corundum (Al₂O₃, for steel), Silicon Carbide (SiC, for non-metallic materials)
By Structure:
Bonded Abrasives: Grinding Wheels, Grinding Points, Oilstones (abrasive grains fixed by a binder)
Coated Abrasives: Sandpaper, Sanding Belts, Sanding Cloth (abrasive grains adhered to a flexible substrate)
Free-Form Abrasives: Abrasive Pastes, Polishing Powders (loose abrasives)
By Process Application:
Surface Grinding Tools
External/Internal Grinding Tools
Tool Sharpening Tools
Precision Polishing Tools
Functions of Abrasive Tools
Precision Machining: Achieve workpiece dimensional accuracy (up to ±0.001mm) and surface roughness (Ra ≤ 0.1μm).
High-Efficiency Cutting: Suitable for rapid removal of high-hardness materials (such as cemented carbide and ceramics). Complex Forming: Gears, threads, and other complex surfaces are machined using forming grinding wheels.
Surface Strengthening: Grinding increases residual compressive stress on the workpiece surface, extending fatigue life.
