Description
Technical field
The present invention relates to a kind of grinding work, in particular to what a kind of pair of workpiece was ground, and polished and be ground has scattered
The preparation method of the grinding tool of heat structure and the grinding tool with radiator structure.
Background technique
Organic grinding tool with radiator structure, which refers to, makees bonding agent with organic molecular compound, and many abrasive grains are fixedly arranged at
Together, it is formed a kind of with certain rigid grinding tool.Organic grinding tool with radiator structure includes with natural and synthesis tree
Rouge does rubber made by grinding tool and natural or synthetic gum cement of the resin made by bonding agent with radiator structure
Grinding tool with radiator structure.
Organic grinding tool with radiator structure is generally made of abrasive material, organic bond and stomata.Wherein, the combination
Agent includes resinoid bond and gum cement.And polyurethane is a kind of gum cement that common gum cement is common,
It is a kind of very special special material, has good operating characteristics, and can be produced by hybrid reaction has heat dissipation
The grinding tool of structure, process costs are very cheap.Meanwhile polyurethane is also a kind of extraordinary soft substance of elasticity, and is had very
Good conjugation, in addition its foaming capacity for having, the porous structure formed on the grinding tool with radiator structure can play
Good chip removal effect has the grinding tool of radiator structure to glass if cooperation Brown Alundum can substitute rare earth polishing as abrasive material
Glass is polished.
But since the heat resistance of polyurethane is very poor, intensity can decline as the temperature rises and sharply.Have
During the grinding tool of radiator structure is ground workpiece, since friction generates huge heat, necessarily to heat dissipation knot
Grinding tool material of structure itself causes very big influence, especially for resinoid bond, gum cement or polyurethane plastics knot
There is mixture the product of the temperature tolerances differences such as grinding tool or its combination of radiator structure to cause tremendous influence --- it is generated in grinding process
Hot conditions under, above-mentioned bonding agent be easy to produce softening, melt carbonization etc. destroy structure variation, directly result in have heat dissipation
The performance failure of the grinding tool of structure, such as abrasive material falls off, sharpness decline, bonding agent softening melting blocking stomata.
Therefore, solving polyurethane with the heat dissipation problem in the grinding tool work of radiator structure is to guarantee there is radiator structure
Grinding tool is capable of a key of normal use.In in many occasions, will use coolant liquid to the grinding tool with radiator structure into
Row cooling.That is, the coolant liquids such as water, emulsion, cooling oil are added in the grinding tool use process with radiator structure.But
It is existing using this method to the grinding tool with radiator structure carry out cooling still there are some problems:
1) when coolant liquid is cooling, the bonding agent to temperature tolerance lower than 200 DEG C has the cooling effect of the grinding tool of radiator structure
It is undesirable；
In environment biggish for Grinding Contact area ratio 2) (contact surface is larger when such as cup emery wheel is ground) coolant liquid is not
Working surface can be entered well, lead to cooling failure；
3) for being hot non-conductor, the height for causing its abrasive material in grinding process locally to generate in conjunction with agent material itself
Temperature quickly cannot pass to form heat dissipation effect at all, therefore also can greatly shadow for the high temperature of up to 800 DEG C of part
The intermediate zone property for arriving abrasive material and bonding agent is rung, abrasive material and bonding agent is made to directly result in the grinding tool with radiator structure in conjunction with bad
Performance sharply declines.
Summary of the invention
The shortcomings that the purpose of the present invention is to solve the above-mentioned prior arts and deficiency provide a kind of with radiator structure
Grinding tool, can in grinding process rapid cooling, guarantee cooling effect and improve cooling efficiency, to guarantee that its own is good
It performance and prolongs its service life.To achieve the goals above, The technical solution adopted by the invention is as follows: a kind of have heat dissipation knot
The grinding tool of structure, the grinding tool are made of integrally formed grinding layer and heat dissipating layer；The heat dissipating layer outer end extends to form multiple outward
Heat sink strip.
As a further improvement of the present invention, heat sink strip is heat sink strip made of heat sink material in the heat dissipating layer.
As a further improvement of the present invention, the width of each heat sink strip is gradually reduced from it from root toward its top, and
The ratio of the width of width and its bottom at the top of it is 0.4~0.6.
As a further improvement of the present invention, the multiple heat sink strip is uniform and arranged in parallel in outside the heat dissipating layer
End, and be sequentially increased per adjacent the distance between two heat sink strips from its root toward the direction at the top of it.
As a further improvement of the present invention, the multiple radiating blocks being staggered, each heat dissipation are equipped in the grinding layer
Block is made of abrasive material, filler material, bonding agent, heat sink material, defoaming agent, curing agent and stabilizer as main component, and every
The percentage that the heat sink material of one radiating block accounts for the gross weight of its all material is 5%~10%.
Through the above technical solutions, the present invention have the grinding tool of radiator structure reached it is following the utility model has the advantages that
1) while guaranteeing to have the cutting hardness of grinding tool of radiator structure, radiator structure is increased on grinding tool, by
This guarantees the heat dissipation performance of grinding tool, so as to the rapid cooling in grinding process, guarantees cooling effect and improves cooling efficiency,
To guarantee its own good performance and prolong its service life；
2) it by will have the grinding tool of radiator structure to be divided into grinding layer and heat dissipating layer, further ensures with radiator structure
Grinding tool grinding hardness while guarantee its heat dissipation performance, further improve in the grinding tool course of work with radiator structure
Radiating efficiency, optimize cooling effect, be conducive to extend the service life of the grinding tool with radiator structure；
3) it by the restriction that component is made of the grinding layer heat dissipating layer to the grinding tool with radiator structure, advanced optimizes
Cooling effect and the service life for extending the grinding tool with radiator structure.
In order to better understand and implement, the invention will now be described in detail with reference to the accompanying drawings.
