Abstract
The utility model relates to a PCD (Polycrystalline Diamond) grinding disc which comprises PCD cutter heads (1) and a substrate (2), wherein 4 sets of PCD cutter heads (1) (i.e. 12 PCD cutter heads) are arranged on the front surface of the substrate (2), and 6 lightening holes are uniformly distributed at the periphery of the substrate (2); each PCD cutter head (1) forms an inclination angle of 10-30 degrees with a horizontal plane and is higher than the surface of the substrate; and a round hole (2b) is arranged in the center of the substrate. The utility model has the advantages that when being used for processing the surface of a cement product, the PCD grinding disc can fast planish an unsmooth cement surface; and particularly, when the cement surface adhered with viscous materials including paints and resins needs to be processed, the superiority of the PCD grinding disc can be better manifested, and the paints can be removed within extremely short time.
Description
Technical field
The utility model relates to a kind of mill, and particularly a kind of PCD mill can be widely used in the removal of cement surface paint and the projection of removal cement surface.
Background technology
In the prior art, cement surface is processed with traditional sintered type diamond disk.In grinding cement process, there is short defective in service life; Especially run into speckling with paint, the cement surface of dopes such as resin, in grinding, dope can wrap up the diamond segment of sintering, and diamond particles can not form cutting edge, makes processing be difficult to carry out.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of process water mud product surface instrument that is more suitable for is provided.
The technical solution of the utility model is: a kind of PCD mill, comprise the PCD cutter head, and matrix, described matrix front is provided with 4 groups of totally 12 PCD cutter heads, is evenly distributed with 6 lightening holes on every side; PCD cutter head and horizontal plane angle of inclination are 10 °-30 °, exceed matrix surface, and the matrix center is provided with circular hole.
The beneficial effects of the utility model are: in process water mud product process, the PCD cutter head with the same fineness of minute surface is not painted the parcel of resin, can remove them easily.The service life of PCD cutter head is considerably beyond the life-span of sintered diamond cutter head, thereby the life-span of mill is significantly promoted, for the consumer provides a kind of cost performance good instrument.
Description of drawings

Fig. 2 is the cutaway view of Fig. 1,
The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2: comprise PCD cutter head 1, matrix 2; Matrix 2 welds together through machining and PCD cutter head 1, and matrix 2 fronts are provided with 4 groups of totally 12 PCD cutter heads 1, are evenly distributed with 6 lightening holes on every side; PCD cutter head 1 is 10 °-30 ° with the horizontal plane angle of inclination, exceeds matrix surface; Matrix 2 centers are provided with circular hole 2b.
Claims (2)
1. a PCD mill comprises PCD cutter head (1), matrix (2); It is characterized in that: described matrix (2) front is provided with 4 groups of totally 12 PCD cutter heads (1), is evenly distributed with 6 lightening holes on every side; PCD cutter head (1) is 10 °-30 ° with the horizontal plane angle of inclination, exceeds matrix surface.
2. PCD mill according to claim 1 is characterized in that the matrix center is provided with circular hole (2b).
