Abstract
The utility model discloses an outer circle grinding wheel. The outer circle grinding wheel solves the problems in the prior art that an annular polishing base body of the grinding wheel is not stable and prone to fragmentation when stressed and raw materials are severely wasted when a product of a large specification is manufactured. The outer circle grinding wheel comprises the polishing base body and the polishing body, the polishing base body is sleeved with the polishing body, a fixing through hole is formed in the axis of the polishing base body, a gradually thinning transition step is arranged on the circular cross section of the polishing base body, and grooves are evenly distributed on the connection face of the polishing base body and the polishing body in the radial direction. The polishing base body is made of a metal alloy, and the polishing body is composed of a binding agent and an abrasive material. The abrasive material is corundum or diamond, and the grooves are circular, oval or polygonal. The outer circle grinding wheel is simple in structure and high in safety, reduces weight under the condition that the polishing base body has enough working strength and balance weight, and meanwhile can reduce cost.
Description
Technical field
This utility model relates to a kind of cutting element, particularly relates to a kind of peripheral milling emery wheel.
Background technology
At present, aspect bar or tube outer diameter grinding and glossing, conventionally adopt cylindrical grinder corase grind to cut the technique that finishing polish matches with buffing wheel.Due to the development of emery wheel technology, the super-abrasive grinding wheel that especially diamond or cubic boron nitride (CBN) abrasive material is made, because of its good grinding performance, has been widely used in the various aspects in grinding field.Existing emery wheel, has a circular polishing matrix, and because the rigidity of polishing matrix is large, side withstand shock ability is poor.In utilizing grinder buffing process, various uncertain reasons and unstablely stressedly all may cause that emery wheel is cracked, just virtually there is certain risk in this, especially in emery wheel High Rotation Speed bruting process, if emery wheel is cracked, its fragment splashes out at a high speed, is easy to hurt operator.Simultaneously when making the larger emery wheel of thickness and diameter, the material of polishing matrix also thicken accordingly, this kind of production technology invisible waste a lot of materials.
Utility model content
The utility model has overcome unstable easy cracked, the serious problem of waste of raw materials while making large specification product when stressed of the circular polishing matrix of prior art medium plain emery wheel, provides a kind of sturdy and durable, the peripheral milling emery wheel of economic security.
Technical solution of the present utility model is, provide a kind of peripheral milling emery wheel with following structure: contain polishing matrix and polishing body, polishing matrix is socketed with polishing body outward, there is fixed via at the place, axle center of polishing matrix, in the circular cross-section of described polishing matrix, have gradually thin transition shoulder, on the joint face of polishing matrix and polishing body, radial equipartition is fluted.Polishing matrix is metal alloy, and polishing body is comprised of bonding agent and abrasive material.Abrasive material is corundum or diamond, and groove is circle, ellipse or polygon.
Compared with prior art, the utility model peripheral milling emery wheel has the following advantages: polishing matrix is provided with gradually thin transition shoulder, by changing the gradually height of thin transition shoulder, in the situation that guaranteeing that polishing matrix has enough working strengths and counterweight, reduce weight, can also reduce costs simultaneously.On the joint face of polishing matrix and polishing body, radial equipartition is fluted, the stability in the time of can strengthening the polishing body running of building.
Accompanying drawing explanation
Fig. 1 is the planar structure schematic diagram of the utility model peripheral milling emery wheel;
Fig. 2 is the structural representation of the utility model peripheral milling emery wheel groove.
The specific embodiment
In accompanying drawing explanation, label 1 is polishing matrix, the 2nd, and fixed via, the 3rd, thin transition shoulder gradually, the 4th, polishing body, the 5th, groove.
Below in conjunction with the drawings and specific embodiments, the utility model peripheral milling emery wheel is described further: as shown in the figure, polishing matrix 1 adopts carbide alloy to make and forms, its cross section is provided with gradually thin transition shoulder 3, in the situation that guarantee required intensity and counterweight under duty, can cut down the thickness of polishing matrix 1, reach saving material, the object of weight reduction, thus reduce costs.Polishing body 4 adopts the abrasive materials such as adhesive and corundum, is looped around on the circumferential surface of polishing matrix 1, by equally distributed groove 5 on circumferential surface, reaches the stable effect connecting.
