Description
Technical field
The present invention relates to one kind grinding work, it is more particularly to a kind of workpiece is ground, polishes and is ground with many
The manufacture method of the grinding tool of layer heat dissipating layer and radiator structure.
Background technology
Organic grinding tool refers to make bonding agent with organic molecular compound, and many abrasive particles are consolidated, and forms a kind of
With certain rigid grinding tool.Organic grinding tool includes doing resin abrasive tools made by bonding agent with natural and synthetic resin,
And the rubber grinding tool made by natural or synthetic gum cement.
Organic grinding tool is typically made up of abrasive material, organic bond and stomata.Wherein, the organic bond includes resin-bonded
Agent and gum cement.And polyurethane is a kind of common gum cement of common gum cement, it is a kind of very special
Different special material, with good operating characteristics, grinding tool can be just produced by hybrid reaction, and process costs are very cheap.
Meanwhile, polyurethane is also a kind of elastic extraordinary soft substance, and with good conjugation, adds its foaming energy having
Power, the loose structure formed on grinding tool can play good chip removal effect, can be with if coordinating Brown Alundum to be as abrasive material
Rare earth polishing abrasive tool is substituted to be polished glass.
But, because the heat resistance of polyurethane is very poor, its intensity can drastically decline with the rising of temperature.In grinding tool
During being ground to workpiece, because friction produces huge heat, very big shadow is necessarily caused in itself to grinding tool material
Ring, especially for the temperature tolerance difference such as resinoid bond, gum cement or polyurethane plastics binding agent grinder or its combination
Product causes tremendous influence --- and under the hot conditions that grinding process is produced, above-mentioned bonding agent easily produces softening, melts carbon
The change of the destruction structure such as change, directly results in the performance failure of grinding tool, and such as abrasive material comes off, sharpness declines, bonding agent softening is molten
Solution blocks stomata etc..
Therefore, it is to ensure the key that grinding tool can be used normally to solve the heat dissipation problem in the work of polyurethane grinding tool.
In many occasions, grinding tool can be cooled down using coolant.That is, during grinding tool use, adding water, emulsification
The coolants such as liquid, cooling oil.But, existing use the method to grinding tool cool down or there are problems that：
1) when coolant is cooled down, the cooling effect of the binding agent grinder to temperature tolerance less than 200 DEG C is undesirable；
In the environment big for Grinding Contact Area comparison 2) (contact surface is larger when such as cup emery wheel is ground) coolant is not
Working surface can be well entered into, causes cooling failure；
3) it is in itself the non-conductor of heat for combining agent material, causes its height that abrasive material is locally produced in grinding process
Temperature quickly cannot pass to form radiating effect at all, therefore high temperature for local up to 800 DEG C also can greatly shadow
The intermediate zone property to abrasive material and bonding agent is rung, abrasive material and bonding agent is drastically declined with reference to the bad grinding tool performance that directly results in.
