Abstract
A resin grinding disc with a supporting layer structure comprises an aluminium base body. An axial center hole is formed in the center of the aluminium base body. A boss is arranged on the side face of the center hole. An inner ring of the upper surface of the aluminium base body and an outer ring of the upper surface of the aluminium base body are respectively provided with a grinding material layer and a supporting layer. The grinding material layer and the supporting layer are both in a round ring shape and are arranged in a concentric mode. The inner wall of the grinding material layer is matched with the outer wall of the supporting layer. The inner wall of the supporting layer is tightly matched with the boss. The supporting layer of the inner ring can be synchronously consumed with the grinding material layer of the outer ring, finishing time of the grinding disc can be reduced, and working efficiency can be improved. Control of speed difference of an interior line and an exterior line which are arranged inside the grinding disc can be achieved through adjustment of the size of the inner diameter of the grinding material layer of a grinding disc product. Chip removal grooves are formed in the grinding material layer and the supporting layer, so that work pieces during grinding are enabled to be cooled and remove chips conveniently. Compared with a grinding disc which is formed by the adoption of a polycyclic bonding technology, the resin grinding disc with the supporting layer structure is low in cost and easy to finish.
Description
Technical field
The utility model belongs to the abrasive grinding technical field, relates in particular to a kind of conventional abrasive material layer that uses as the resin mill of supporting layer structure.
Background technology
For a long time, the mill product of major diameter broad wall has obtained the extensive employing of producer due to advantages such as having processing continuity, operating efficiency height in the through type Grinding Process.Yet there is following problem in this type of mill product in the through type grinding process: the Internal and external cycle abrasive material consumes inhomogeneous, and is difficult for finishing.This problem has hindered the further application development of mill product on market.
By analysis, the reason that these problems occur is that mill product end surface area is large, internal and external line speed difference large (External Cordon Line speed is higher, and blue band outer edge line speed is lower) in grinding process, and external diameter is larger or rotating speed is higher, and difference is more obvious.With the external diameter 500mm of present production, the mill product of endoporus 60mm is example, and the use rotating speed of producer in process is 900rpm/min, as calculated, this moment, mill outmost turns linear velocity was 23.55m/s, and endoporus circumference place linear velocity is only 2.826m/s, 8.33 times of internal and external line speed differences.So large linear velocity missionary society increases considerably the mill inequality extent that the Internal and external cycle abrasive material consumes in grinding process, presents high outside and low outside phenomenon (consumption of inner ring abrasive material is very fast, and outer ring abrasive material consumption is slow).Just need to carry out equating to whole mill face this moment, but because the mill face area is large, dressing process takes time and effort, and has reduced working (machining) efficiency.
The solution that present producer generally adopts has following two kinds: (1) inner ring adopts iron plate to do support, in the through type grinding process, and outer ring abrasive material grinding work piece, inner ring iron plate is done support.The benefit of doing like this is to have reduced linear differential, and then has reduced the consumption degree of irregularity of Internal and external cycle abrasive material; Shortcoming is not wear and tear as the iron plate of supporting layer, needs constantly the height of iron plate to be adjusted; (2) mill of the many rings of producer's buying bonding process moulding, this kind structure mill adopt mosaic sheet, annulus, secter pat abrasive material bonding to form more.The advantage of the method is to reduce by emery wheel piece hardness Nonlinear Design the difference of hardness of Internal and external cycle abrasive material, reduces abrasive material and consumes degree of irregularity; Shortcoming is that the mill production cycle is long, and cost of manufacture is high, purchases the also corresponding raising of cost of producer.
The utility model content
To be solved in the utility model is that mill product Internal and external cycle abrasive material in the through type grinding process consumes technical problem inhomogeneous, the difficult finishing of product, thereby a kind of novel, rational resin mill with the supporting layer structure is provided.
In order to address the above problem by the following technical solutions: a kind of resin mill with the supporting layer structure, comprise aluminum substrate, the aluminum substrate center is provided with axial center hole, the centre bore side is provided with boss, the inner ring of aluminum substrate upper surface and outer ring are respectively equipped with abrasive material and supporting layer, abrasive material and supporting layer are circular and concentric setting, and abrasive material inwall and supporting layer outer wall are complementary, and supporting layer inwall and boss closely cooperate.
Described abrasive material is the working lining that diamond or cubic boron nitride are made, and is directly molded on aluminum substrate by pressure sintering.
The tablet that described supporting layer mainly is mixed by carborundum, boron carbide and bond, tablet is bonded on aluminum substrate.
Described abrasive material and supporting layer are provided with the chip area of radially offering.
Inner ring supporting layer of the present utility model can with outer ring abrasive material synchronous consumption, reduce the mill finishing time, enhance productivity; Can be by adjusting the realization of mill product abrasive material internal diameter size to the control of mill internal and external line speed difference; Leave chip area on abrasive material and supporting layer, the work-piece cools when being convenient to grinding and chip removal.Compare with the mill that adopts the moulding of many ring bonding processes, cost is low, and finishing easily.
