1. Определение шлифовальных кругов:
Шлифовальный круг - это абразивный инструмент, изготовленный из абразивов и связующего вещества, производится с помощью таких процессов, как прессование и выпечка. 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, etc.
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, etc.
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, etc.
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, etc.
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 and 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, etc.
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.
