Abstract
The utility model discloses a coreless grinding wheel and belongs to the technical field of a grinding tool made from super-hard material. The coreless grinding wheel comprises a base body and a grinding layer stuck onto the base body, wherein the base body is in a concave shape; the coreless grinding wheel is formed by two grinding wheels fastened together; the two grinding wheels are fixedly connected via a pin; and the grinding layer is a pressed layer formed by diamond grinding material and binding agent. The base body in the coreless grinding wheel is in a concave shape; the weight of the base body can be reduced without increasing strength and counterweight; cost can be reduced; and the two grinding wheels are fastened via the pin, so the coreless grinding wheel can be used with more convenience.
Description
Technical field
The utility model relates to superhard material grinding tool technical field, particularly relates to a kind of centreless grinding abrasive disk.
Background technology
Superhard material grinding tool comprises diamond abrasive tool and CBN, the main Pattern In Grinding Cemented Carbide of diamond abrasive tool and hard crisp nonmetallic materials, the main grinding iron group of CBN metalloid material.The cylindrical position of the main grinding work piece of centreless grinding abrasive disk.
Centreless grinding abrasive disk is generally made up of working lining, matrix, transition zone three parts.Working lining is abrasive material, formed by diamond or cubic boron nitride abrasive materials, bonding agent and filler, and be the part that grinding tool is used for carrying out grinding.Transition zone is made up of bonding agent and other materials, and or not containing super hard abrasive, its effect is not securely being held on matrix, to guarantee the abundant use of working lining by working lining.In the last few years, some factories had cancelled transition zone, directly working lining handle were held on matrix.Matrix is the basic body of grinding tool, plays a part support performance layer, by flange, fixture by grinding tool securely clamping on lathe.
Traditional centreless grinding abrasive disk is to be fixed together by three emery wheels, and this emery wheel seam is many, uses very inconvenient.
Utility model content
For overcoming problems of the prior art, the utility model provides a kind of centreless grinding abrasive disk easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of centreless grinding abrasive disk, and comprise matrix and stick on the abrasive material on matrix, described matrix is " recessed " font, described centreless grinding abrasive disk is that two emery wheels are fixed together, and two emery wheels adopt pin to be fixedly connected with.
Described abrasive material is the neutralizing layer of diamond abrasive and the common composition of bonding agent.
Described matrix is that steel or aluminium alloy are made.
Useful good effect of the present utility model is: the utility model is arranged to matrix " recessed " font, the in the situation that of proof strength, counterweight, can reduce the weight of matrix, reduces costs; Be arranged in addition two emery wheels and adopt pin to be fixed together, use convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model centreless grinding abrasive disk;
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure: 1, matrix, 2, abrasive material, 3, emery wheel one, 4, emery wheel two.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Referring to Fig. 1, Fig. 2, a kind of centreless grinding abrasive disk of the utility model, comprises matrix 1 and sticks on the abrasive material 2 on matrix, described matrix 1 is " recessed " font, described centreless grinding abrasive disk is that emery wheel 1 and emery wheel 24 are fixed together, and two emery wheels adopt pin to be fixedly connected with.
Described abrasive material 2 is the neutralizing layer of diamond abrasive and the common composition of bonding agent.
Described matrix 1 is made for steel or aluminium alloy.
The utility model centreless grinding abrasive disk, by matrix being arranged to " recessed " font, the in the situation that of proof strength, counterweight, can reduce the weight of matrix, reduces costs; This centreless grinding abrasive disk is arranged to two emery wheels and is adopted pins to be fixed together in addition, uses convenient.
Claims (3)
1. a centreless grinding abrasive disk, comprises matrix and sticks on the abrasive material on matrix, it is characterized in that, described matrix is " recessed " font, and described centreless grinding abrasive disk is that two emery wheels are fixed together, and two emery wheels adopt pin to be fixedly connected with.
2. centreless grinding abrasive disk according to claim 1, is characterized in that, described abrasive material is the neutralizing layer of diamond abrasive and the common composition of bonding agent.
