Problems solved by technology

[0002] The double-sided flat grinding machine uses cast iron discs, combined with abrasive liquid (suspending agent, dispersant, diamond, boron carbide, alumina micropowder, etc.), to carry out horizontal grinding processing on workpieces (sapphire, glass, etc.) to achieve reduction Thinning and polishing purposes, in the field of precision grinding technology, although this method has been used in a large area, there are big problems in terms of grinding efficiency, environmental pollution, and employee occupational health, and it is difficult to control the machining accuracy. In the process, it is easy to cause slow processing time, produce a large amount of sewage and threaten the personal health of operators, which is a high-consumption and low-efficiency processing method.

Embodiment 1

[0019] A particle composition for grinding, the components of which include in parts by weight: diamond (10 μm, concentration 1.8 carats / cm 3 ) 22g, 53g of aluminum oxide, 19g of zirconia, 4g of silicon dioxide, 1.5g of calcium stearate, 0.8g of KH550, 19g of epoxy resin powder and 5g of glass fiber.

[0020] Method of use: Use a circular plate (specification Φ578*Φ180mm) combined with PC and PVC as a carrier, uniformly bond or weld the particle composition on the surface of the carrier to form a grinding disc, and then fix the grinding disc on the double-sided adhesive On the surface grinder, the grinding disc is driven by the double-side grinder to grind the surface of the workpiece to be processed. During the grinding process, the recyclable cleaning fluid is used to rinse the surface of the workpiece to be processed.

Embodiment 2

[0022] A particle composition for grinding, the components of which include in parts by weight: diamond (50 μm, concentration 2.5 carats / cm 3 ) 30g, aluminum oxide 28g, zirconia 17.5g, silicon dioxide 8.5g, calcium stearate 4g, KH560 1.6g, phenolic resin powder 24g and glass fiber 8g.

[0023] Method of use: Use a circular plate (specification Φ578*Φ180mm) combined with PC and PVC as a carrier, uniformly bond or weld the particle composition on the surface of the carrier to form a grinding disc, and then fix the grinding disc on the double-sided adhesive On the surface grinder, the grinding disc is driven by the double-side grinder to grind the surface of the workpiece to be processed. During the grinding process, the recyclable cleaning fluid is used to rinse the surface of the workpiece to be processed.

Embodiment 3

[0025] A particle composition for grinding, the components of which include in parts by weight: diamond (100 μm, concentration 3.2 carats / cm 3 ) 40g, aluminum oxide 43g, zirconia 15g, silicon dioxide 3g, calcium stearate 3g, KH570 0.6g, epoxy modified phenolic resin powder 16g and glass fiber 6g.

Abstract

The invention belongs to the technical field of precision grinding, and particularly relates to a particle composition for grinding. The composition in the form of a solid columnar particle and acts on the surface of a to-be-machined workpiece in the thinning and polishing process of the to-be-machined workpiece to achieve grinding effect; so on the basis that the surface roughness of the workpiece is accurately controlled, grinding efficiency is improved, manpower and material resource input is saved, and the problems of high cost, production pollution discharge and the like are solved. In addition, directed at the requirements of rough thinning, fine thinning, different products, different product roughness and the like, the particle composition can accurately meet diversified requirements of products by using diamonds with different particle sizes and concentrations.

Description

technical field [0001] The invention belongs to the technical field of precision grinding, and in particular relates to a granular composition for grinding. Background technique [0002] The double-sided flat grinding machine uses cast iron discs, combined with abrasive liquid (suspending agent, dispersant, diamond, boron carbide, alumina micropowder, etc.), to carry out horizontal grinding processing on workpieces (sapphire, glass, etc.) to achieve reduction Thinning and polishing purposes, in the field of precision grinding technology, although this method has been used in a large area, there are big problems in terms of grinding efficiency, environmental pollution, and employee occupational health, and it is difficult to control the machining accuracy. In the process, it is easy to cause slow processing time, produce a large amount of sewage and threaten the personal health of operators, which is a high-consumption and low-efficiency processing method. [0003] Therefore...
