Abstract
The utility discloses a plastic inner elastic grinding disc with outer thread, which comprises a plastic substrate disc with mounting member, and a grinding layer on the substrate disc, wherein the grinding layer is composed of a plurality of abrasive cloths staggeredly adhered on the working surface of the substrate disc along the circumference direction. This configuration endows the grinding layer with elasticity while ensuring support function of the substrate disc such that the workpiece can be prevented from being burned in polishing and grinding process. The outer diameter of the grinding layer is larger than that of the substrate disc, which improves polishing and grinding of workpiece with curved surface, and the utility model has low polishing noise without causing the noise pollution to environment.
Description
Technical field
The utility model relates to the mill that grinding is used, and especially relates to the outer silk of plastic substrate Circular back-plate for carrying flexible abrasive material.
Background technology
Abrasive material is widely used in field of machining.Make mill as abrasive material particles being bonded on the matrix dish that is provided with installation component, be used for, to play purpose surface of the work grinding, polishing to metal and nonmetallic grinding.The existing deficiency of above-mentioned mill mainly shows as: abrasive material particles directly applies and is bonded on the matrix dish, because the matrix dish also has the installation supporting role, therefore rigidity is bigger, grinding layer contacts with the workpiece rigidity, cause surface of the work is ground, easy burn workpiece in the polishing process, curved surface to workpiece grinds, polishing effect is relatively poor, and the bruting process noise causes noise pollution to environment greatly simultaneously.
The utility model content
The utility model purpose is to provide silk Circular back-plate for carrying flexible abrasive material outside a kind of plastic substrate at above-mentioned existing in prior technology deficiency.
For achieving the above object, the utility model can be taked following technical proposals:
The outer silk of plastic substrate described in the utility model Circular back-plate for carrying flexible abrasive material, it comprises the matrix dish that is provided with installation component, with the grinding layer that is arranged on this matrix dish, described matrix dish is made by plastic material, described grinding layer be the polylith emery cloth along the circumferential direction staggered fall to put be bonded on the matrix dish work card; Described installation component is the round platform and the connecting thread that is opened on this round platform outer peripheral face that is arranged on matrix disk center position.
Described emery cloth is a rectangular configuration, and it is staggered to fall and put the grinding layer external diameter the made external diameter greater than described matrix dish.
Described grinding layer is the anchor ring structure.
Advantage of the present utility model be to take with described grinding layer be arranged to by the polylith emery cloth along the circumferential direction staggered fall to put be bonded in this architectural feature on the matrix dish work card, therefore have at assurance matrix dish and meet under the precondition that supporting role is installed, grinding layer has certain elasticity, to surface of the work grind, in the polishing process not can] the burn workpiece; Staggered to fall another advantage of grinding layer of putting be the external diameter that its external diameter can be made greater than the matrix dish by emery cloth, make to curve surface work pieces grind, polishing effect is better.The bruting process noise is little simultaneously, can not cause noise pollution to environment.

The specific embodiment
As shown in the figure, the outer silk of plastic substrate described in the utility model Circular back-plate for carrying flexible abrasive material, it comprises the matrix dish 2 that is provided with installation component 1, with the grinding layer 3 that is arranged on this matrix dish 2, described matrix dish 2 is made by plastic material, described grinding layer 3 falls for polylith rectangle emery cloth 4 is along the circumferential direction staggered to put and is bonded on the matrix dish 2 work cards, and the external diameter of grinding layer 3 is greater than the external diameter of matrix dish 2 and be the anchor ring structure.Described installation component is the round platform and the connecting thread that is opened on this round platform outer peripheral face that is arranged on matrix dish 2 centers.
