Description
Technical Field
The utility model relates to a emery wheel field of making, concretely relates to cavity PCD emery wheel.
Background
The grinding wheel is a bonded grinding tool which is formed by bonding a common grinding material into a certain shape (mostly circular, with a through hole in the center) by a bonding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classes of binders, ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels are common. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.
The scraps produced during grinding are easy to be blocked into other parts in work, so that the problems of component failure and the like are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cavity PCD emery wheel to better processing sweeps problem in the middle of the grinding.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
a hollow PCD grinding wheel comprising:
the upper end surface of the grinding wheel base body is provided with an annular grinding wheel working layer, an annular PCD grinding wheel is arranged on the annular grinding wheel working layer,
a plurality of chip removal chutes are annularly arranged on the annular grinding wheel working layer;
the peripheral chip removal surface of the annular grinding wheel working layer is provided with a plurality of chip removal grooves
A hollow flange connecting end penetrates through the middle part of the grinding wheel base body, and an annular chip removal cavity which is inwardly contracted is concavely arranged at the joint of the hollow flange connecting end and the upper end face;
a plurality of chip removal pipelines are arranged in the annular chip removal cavity.
In a preferred embodiment of the present invention, the side end of the grinding wheel base is inwardly shrunk to form a side inclined surface.
In a preferred embodiment of the present invention, the inclination angle of the side slope is 45 °.
In a preferred embodiment of the present invention, the grinding wheel base is made of aluminum.
In a preferred embodiment of the present invention, the inclination angle of the annular debris discharge chamber is 46 °.
In a preferred embodiment of the invention, the inclination angle of the debris discharge chute is 110 °.
The beneficial effects of the utility model reside in that:
the utility model provides a cavity PCD emery wheel is the setting of the chip removal pipeline through chip removal face, chip groove and the base member of emery wheel working layer to better sweeps problem in the middle of the processing grinding.
