1. Definition of Grinding Wheels:
A grinding wheel is an abrasive tool made from abrasives and a bonding agent, manufactured through processes like pressing and baking. The three key components of a grinding wheel are the abrasive grains, the bonding agent, and the pores.
2. Classification of Grinding Wheels:
By Abrasive Material:
Superabrasive Grinding Wheels: Diamond grinding wheels and CBN (cubic boron nitride) grinding wheels.
Conventional Grinding Wheels:
Alumina-based Grinding Wheels: e.g., white alumina grinding wheels, brown alumina grinding wheels, single crystal alumina grinding wheels, and others.
Silicon Carbide-based Grinding Wheels: e.g., green silicon carbide grinding wheels, black silicon carbide grinding wheels, և այլն.
By Bonding Agent: Resin-bonded grinding wheels, Metal-bonded grinding wheels (bronze grinding wheels), Ceramic-bonded grinding wheels, Electroplated grinding wheels
By Grain Size: Coarse grinding wheels, Semi-fine grinding wheels, Fine grinding wheels, Polishing wheels
By Shape: Cup-shaped grinding wheels, Bowl-shaped grinding wheels, Disc-shaped grinding wheels, Cylinder-shaped grinding wheels, Parallel grinding wheels, Double-sided recessed grinding wheels, Parallel arc grinding wheels, Single-sided reinforced grinding wheels, Double-sided reinforced grinding wheels, և այլն.
By Application: Grinding wheels for the sanitary paper industry, Grinding wheels for the corrugated paper industry, Grinding wheels for the metal industry, Grinding wheels for the non-metal industry, և այլն.
3. Specifications of Grinding Wheels:
Different abrasives, bonding agents, grain sizes, and concentrations have varying effects on grinding wheels.
4. Applications of Grinding Wheels:
Grinding wheels are used in various fields including air conditioning compressor parts, bearing inner holes, non-ferrous metal inner hole grinding, ceramic materials, magnetic materials, PCD tools, PCBN tools, CRT glass shells, hydraulic parts, cast iron, stainless steel, heat-resistant alloys, and various other materials and workpieces.
5. Functions of Grinding Wheels:
Grinding wheels are used in different grinding processes such as channel grinding, thread grinding, rail grinding, gear grinding, static pressure sedimentation channel grinding, և այլն.
6. Applications of Different Shapes of Grinding Wheels:
Flat Series Grinding Wheels: Widely used for internal cylindrical, external cylindrical, surface, centerless, tool cutting, slotting, and free grinding.
Flat Arc Edge Grinding Wheels: Used for grinding the grooves of taps and the curved surfaces of bearing raceways.
Flat Reinforced Arc Grinding Wheels: Effectively increase the support strength of the base, ensuring the precise requirements for grinding the arc surfaces of workpieces.
Disc-shaped Type 3 Grinding Wheels: Suitable for various coordinate grinding machines, tool grinding machines, and specialized grinding machines for complex tools, specifically for processing high-speed steel and carbide rotary files, craft drills, dental drills, milling cutters, and gemstone and ceramic products.
Cylinder Grinding Wheels: Mainly used for grinding flat surfaces on vertical axis surface grinding machines.
Conical Grinding Heads: Used for grinding various groove shapes and trimming edges.
Cylindrical Grinding Heads: Mainly used for internal cylindrical grinding, grinding special internal cylindrical surfaces and mold inner walls, and deburring.
Cylinder Slot Grinding Wheels: Mainly used for grinding drill tips and turning tools, with a tapered dovetail groove that can be mounted on the grinding machine drive plate for convenience.
Double-bevel Type 1 Grinding Wheels: Mainly used for grinding gear teeth and single-line threads.
Double-bevel Type 2 և 3 Grinding Wheels: Used for external cylindrical and end-face grinding.
Single-bevel Type 1 Grinding Wheels: Mostly used for grinding various saw teeth.
Single-bevel Type 2 Grinding Wheels: With an angle less than 30°, used for sharpening various milling cutters, reamers, gear shapers, և այլն.
Single-sided Convex Grinding Wheels: Designed for easy mounting of large-diameter, thin grinding wheels on flanges, used similarly to flat grinding wheels.
Single-sided Concave Grinding Wheels: Used for internal cylindrical and surface grinding; larger diameters are used for external cylindrical grinding.
Double-sided Concave Grinding Wheels: Used for external cylindrical grinding and tool sharpening, also for the grinding and guiding wheels in centerless grinding.
Single-sided Concave Tapered Grinding Wheels: Used for external cylindrical and end-face grinding, such as crankshaft journal grinding.
Thin Grinding Wheels: Used for cutting and slotting according to different process requirements.
Other Shapes of Grinding Heads: Mainly for grinding special internal cylindrical surfaces.
