Description

A kind of grinding tool with radiator structure

Technical field

The utility model is related to a kind of grinding work, more particularly to a kind of tool for being ground to workpiece, polish and being ground Have a grinding tool of radiator structure, and this this have radiator structure grinding tool preparation method.

Background technology

Organic grinding tool with radiator structure to be referred to and make bonding agent with organic molecular compound, many abrasive particles are fixedly arranged at Together, form a kind of with certain rigid grinding tool.Organic grinding tool with radiator structure is included with natural and synthesis tree Fat does the grinding tool that the resin made by bonding agent has radiator structure, and the rubber made by naturally occurring or synthetic gum cement Grinding tool with radiator structure.

Organic grinding tool with radiator structure is typically made up of abrasive material, organic bond and pore.Wherein, the combination Agent includes resinoid bond and gum cement.And polyurethane is a kind of common gum cement of common gum cement, It is a kind of very special special material, with good operating characteristics, just can be produced with radiating by hybrid reaction The grinding tool of structure, process costs are very cheap.Meanwhile, polyurethane is also a kind of elastic extraordinary soft substance, and with very Good conjugation, adds its foaming capacity having, and the loose structure formed on the grinding tool with radiator structure can be played Chip removal effect well, if coordinating Brown Alundum to substitute rare earth grinding tool of the polishing with radiator structure to glass as abrasive material Glass is polished.

But, because the heat resistance of polyurethane is very poor, its intensity can drastically decline with the rising of temperature.Have During the grinding tool of radiator structure is ground to workpiece, because friction produces huge heat, necessarily to radiating knot The grinding tool material of structure causes in itself very big impact, especially for resinoid bond, gum cement or polyurethane plastics knot The product that mixture has the temperature tolerance difference such as the grinding tool of radiator structure or its combination causes tremendous influence --- produces in grinding process Hot conditions under, above-mentioned bonding agent easily produce softening, melt carbonization etc. destruction structure change, directly result in radiating The performance failure of the grinding tool of structure, such as abrasive material come off, sharpness declines, bonding agent softens melting blocking pore.

Therefore, solve polyurethane to have the heat dissipation problem in the grinding tool work of radiator structure is to ensure there is radiator structure The key that grinding tool can be used normally.In many occasions, the grinding tool with radiator structure can be entered using coolant Row cooling.That is, during the grinding tool use with radiator structure, adding the coolants such as water, emulsion, cooling oil.But, Existing employing the method is cooled down or there are problems that to the grinding tool with radiator structure：

1) when coolant is cooled down, there is the cooling effect of the grinding tool of radiator structure to bonding agent of the temperature tolerance less than 200 DEG C It is undesirable；

2) in the environment big for Grinding Contact Area comparison (contact surface is larger when being ground such as cup emery wheel) coolant is not Working surface can be well entered into, cause cooling failure；

3) for being the non-conductor of heat with reference to agent material itself, the height that abrasive material local produces in grinding process for it is caused Temperature quickly cannot pass to form radiating effect at all, therefore for local up to 800 DEG C of high temperature also can greatly shadow The intermediate zone property to abrasive material and bonding agent is rung, makes abrasive material and bonding agent directly result in the grinding tool with radiator structure with reference to bad Performance drastically declines.
