Abstract
The utility model discloses a grinding wheel. The grinding wheel comprises a grinding disk, sand paper and an elastic layer which is adhered between the grinding disk and the sand paper. The utility model also relates to a polishing or burnishing tool, which comprises a burnishing unit with the grinding wheel. The grinding wheel and the polishing or burnishing tool have higher burnishing fineness and can improve the burnishing efficiency of fine components on one hand, and have higher abrasive resistance, reduce material consumption and save use cost on the other hand.
Description
Technical field
The utility model relates to a kind of grinding tool, particularly a kind of grinding abrasive disk and polishing or milling tools that precise part is polished.
Background technology
The grinding abrasive disk of prior art is as a kind of consumptive material, is installed on polishing or the milling tools, and the high speed rotation through grinding abrasive disk makes itself and the polished or parts contact friction of waiting to polish, thus the purpose of realization sanding and polishing.
Known, the grinding abrasive disk that is used for the polishing grinding of precise part (like the link rotating shaft of notebook computer) mainly is made up of mill main body and sand paper.The polishing of this grinding abrasive disk is meticulous inadequately, be inappropriate for the polishing requirement for this precise part, and yield rate is lower, and the loss of sand paper consumptive material is also comparatively serious.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of polish novel grinding abrasive disk and polishing or milling tools meticulous and the saving consumptive material.
The utility model provides following technical scheme:
A kind of grinding abrasive disk comprises mill and sand paper, also comprises the elastic layer that is pasted between said mill and the sand paper.Owing between mill and sand paper, be provided with elastic layer; Can play the good effect of elastic deformation; The surface of fitting more easily when making polishing and waiting to polish parts; Increase the polishing contact-making surface of unit are sand paper thus, and then improved the fineness of polishing, more effectively polish the tiny convexity and the coarse part on precise part surface.
Preferably, said elastic layer is all identical with the area of said sand paper and said mill.
Particularly, said elastic layer is the elastic gum cortex.
Especially, grinding abrasive disk of the present invention is for roller bearing, and is cylindrical and the curved surface parts are more suitable.And because this elastic gum cortex is softer relatively, the cushioning effect in the time of can playing polishing can effectively reduce in the grinding abrasive disk bruting process loss to flour milling.
Further, said elastic gum skin thickness is 1-4mm.Elastic gum cortex in this thickness range can both keep preferable elastic force, was convenient to the operation of polishing again, when having guaranteed precision and the dynamics of polishing, had fabulous cushioning effect again.
Preferably, the density of said sand paper is 400-1000 grain per square inch number.Sand paper in this density range is applicable to the polishing of precise part, improves the efficient of polishing.
The utility model also provides a kind of polishing or milling tools, comprises the polishing unit that aforesaid grinding abrasive disk is installed.
To sum up, grinding abrasive disk of the utility model and polishing or milling tools are owing to be provided with the elastic gum cortex between mill and sand paper; Has preferable polishing fineness on the one hand; Can improve the grinding efficiency of meticulous parts, to roller bearing, cylindrical and the curved surface parts are more suitable; On the other hand, stronger wearability is arranged again, reduced consumptive material, practice thrift use cost.
Description of drawings
Fig. 1 is the structural representation of the utility model grinding abrasive disk embodiment.
The specific embodiment
Do further explain below in conjunction with 1 pair of the utility model of accompanying drawing.Grinding abrasive disk as shown in fig. 1 comprises the mill 1, elastic gum cortex 2 and the sand paper 3 that connect successively.Wherein, elastic gum cortex 2 is pasted between mill 1 and the sand paper 3.Three's area is identical.Preferably, the thickness of elastic gum cortex 2 is 1-4mm.The density of sand paper 3 is 400-1000 grain per square inch number.
When polishing, grinding abrasive disk is installed on polishing/milling tools, start polishing/milling tools, for example to rotate at a high speed through the driven by motor grinding abrasive disk, the sand paper 3 on the grinding abrasive disk and the parts CONTACT WITH FRICTION of waiting to polish wait to grind the parts sanding and polishing thereby make.Likewise, this grinding abrasive disk also can not rely on the motor of polishing/milling tools and use by hand separately.Only need to wait to grind parts, also can reach the polishing purpose in the manual friction in sand paper 3 surfaces.
More than through the mode of exemplary embodiment the utility model is carried out exemplary explanation, but the utility model is not limited thereto.Be construed as, under the situation of the design that does not depart from the utility model, operation principle, the material among the above embodiment, connected mode, size or parameter can be replaced through other replacement or equivalent processes that present technique field personnel know.
Claims (6)
1. a grinding abrasive disk comprises mill and sand paper, it is characterized in that, also comprises the elastic layer that is pasted between said mill and the said sand paper.
2. grinding abrasive disk as claimed in claim 1 is characterized in that, said elastic layer is all identical with the area of said sand paper and said mill.
