Description
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.
Utility model content

Good performance and its service life of prolongation.To achieve these goals, the technical solution adopted in the utility model is as follows：One kind tool
There is the grinding tool of radiator structure, the grinding tool is made up of integrally formed grinding layer and heat dissipating layer；The heat dissipating layer outer end extends outward
Form multiple heat sink strips.
Used as further improvement of the utility model, heat sink strip is heat sink strip made by heat sink material in the heat dissipating layer.
Used as further improvement of the utility model, the width of each heat sink strip is gradually subtracted from it from root toward its top
It is little, and the width at the top of it and the ratio of the width of its bottom are 0.4～0.6.
Used as further improvement of the utility model, the plurality of heat sink strip is uniform and arranged in parallel in the radiating
Layer outer end, and often the distance between two adjacent heat sink strips are increased successively from its root toward the direction at the top of it.
As further improvement of the utility model, the multiple radiating blocks being crisscross arranged are provided with the grinding layer.
By above-mentioned technical proposal, there is the utility model the grinding tool of radiator structure to have reached following beneficial effect：
1) while the cutting hardness of the grinding tool with radiator structure is ensured, radiator structure is increased on grinding tool, by
This ensures the heat dispersion of grinding tool such that it is able to the quick heat radiating in grinding process, it is ensured that cooling effect and raising cooling effectiveness,
So as to ensureing its own good performance and extending its service life；
2) by the way that the grinding tool with radiator structure is divided into into grinding layer and heat dissipating layer, further ensure with radiator structure
Grinding tool grinding hardness while ensure its heat dispersion, in further increasing the grinding tool course of work with radiator structure
Radiating efficiency, optimize cooling effect, be conducive to extend with radiator structure grinding tool service life；
3) by the restriction for making component of the grinding layer heat dissipating layer to the grinding tool with radiator structure, further optimize
The service life of the grinding tool of cooling effect and prolongation with radiator structure.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
