The specific embodiment
Fig. 1 is the sectional view of a kind of grinding tool of the present invention.With adhesive 12 coatings, abrasive particle 13 is bonded on the substrate 11 by adhesive 12 on the surface of substrate 11.
Many eyelets 14 in grinding tool, have been formed.Also can use the lacuna that does not pass the substrate rear surface to replace eyelet.Abrasive dust and the abrasive particle that comes off are collected and are retained in eyelet or the lacuna, thereby prevent to form on the surface that will grind the wire scratch effectively.And, when using eyelet, can prevent effectively that polished surface from adhering on the abrasive particle coating surface of grinding tool, provides improved grinding efficiency thus.
The shape of lacuna or eyelet has no particular limits, as long as they form in separate mode, and does not form continuous recess.For example, the shape that is fit to is selected from circle, ellipse and polygon, as hexagon, square, rhombus or triangle.
About lacuna or eyelet, when they too hour, can produce obstruction, thereby cause efficient reduction of collecting abrasive dust etc.When lacuna or eyelet were too big, the intensity of grinding tool and grinding efficiency descended.Therefore, the size of lacuna or eyelet is preferably about 2-8% (diameter ratio) of grinding tool external diameter.
More specifically, with regard to the size of lacuna or eyelet, be that diameter is about 0.5-10mm, is more preferably about 2-6mm under the situation of circle at lacuna or eyelet, at lacuna or eyelet is under the foursquare situation, and the foursquare length of side is about 0.2-10mm, is more preferably about 2-6mm.
Lacuna or eyelet should be distributed on the whole lapped face of grinding tool.When existing on the lapped face when not having lacuna or eyelet regional, abrasive dust can't be collected in this zone, and grinding tool will adhere on the polished object, causes the reduction of grinding efficiency.
Do not need all lacunas or eyelet all to be of similar shape and size.Those lacuna or eyelets with difformity and size can form in the mode of mixing, as long as they are distributed on the whole surface of grinding tool.But, preferably they are arranged regularly.
Each lacuna on face of grinding tool or the edge of eyelet are preferably oblique.When the edge of each lacuna on face of grinding tool or eyelet when being sharp or outstanding, can damage polished surface.
Eyelet should be handled and forms by grinding tool being carried out punching.When grinding tool is carried out punching, preferably blade is inserted rear surface until substrate from lapped face.So just can in each eyelet on face of grinding tool, form hypotenuse.But eyelet also can carry out punching to substrate and form before the coating of grinding tool.
Lacuna should be handled and forms by substrate being carried out embossing.And lacuna can also form by clone method.These methods can form to be had evenly and the lacuna of regular shape, and the degree of accuracy when grinding in order to improve grinding tool and fineness quality also form hypotenuse in each lacuna on face of grinding tool.
About grinding tool of the present invention, the grinding tool surface is preferably about 50-96% with effective contact area of polished object.Better, under the situation of using the used hand-ground piece of wet-milling, effectively contact area is preferably about 75-90%, is more preferably about 80-85%.Effectively contact area is meant that the zone on the grinding tool surface that does not comprise lacuna or eyelet accounts for the ratio (%) in the zone of the grinding tool that does not have lacuna or eyelet.
Effectively contact area has just increased the load that is applied in the process of lapping on the abrasive particle less than 50%, and causing peeling off the abrasive particle that gets off increases, thereby has reduced grinding efficiency.Effectively contact area surpasses about 96% grinding efficiency that improvement can't be provided.
