Abstract

The utility model relates to a sector high tooth diamond circular saw blade comprising a cutter head 1 and a base body 2; wherein the cutter head 1 takes the sector segment type, and the clearance between the cutter head takes a V shape; the height of the cutter head is 15mm, the base body 2 takes an annular shape; the center of the base body is provided with a central hole 2a which is connected with an electric tool, the diameter of the central hole is 20mm, and the circumference of the hole is evenly distributed with four semicircles 2b of which the radius is 2mm. The utility model has the advantages that the circular saw blade solves the defects of the existing common diamond circular saw blade, and provides a sintered sector high tooth diamond circular saw blade which has beautiful appearance, firmness and durability, sharp cutting and no easy deformation of the base body, and the saw blade can be used in the cutting and processing of various stones.

Description

Fan-shaped high tooth diamond disc

Technical field

The utility model relates to a kind of diamond disc, and the fan-shaped high tooth diamond disc of particularly a kind of sintered type is mainly used in the cutting of stone materials product.

Background technology

Diamond disc is mostly adopted in the cutting of fragile materials such as China's stone material, because applicability is wide, many, the work under bad environment of processing stone material kind, traditional diamond saw blade mostly can not satisfy user's instructions for use, matrix distortion, drawing crack often appear, the cutter head distortion, poor safety performance, phenomenons such as the life-span is short, the block saw blade cutting speed of joint is fast, efficient is high though the most important thing is to adopt, but problems of splitting of ubiquity matrix all, this also is an industry difficult problem, and adopts continuous rack saw sheet, then cutting speed is slow, is not mostly accepted by the user.

The utility model content

The purpose of this utility model is to overcome the technical deficiency in the existing diamond saw blade cutting, provides a kind of sturdy and durable, cut sharp, the fan-shaped high tooth diamond disc of the on-deformable sintered type of matrix.

The technical solution of the utility model is: a kind of fan-shaped high tooth diamond disc, comprise cutter head, matrix, cutter head is made up of metal dust and diamond particles, it is block to be fan-shaped joint, the space is V-shaped between the cutter head, and the cutter head height is 15 millimeters, and matrix links to each other at periphery with cutter head, be annular, the center is provided with the centre bore that is connected with electric tool, and the hole is 20 millimeters of diameters, and to be evenly distributed with 4 radiuses on the circumference be 2 millimeters semicircles.

The beneficial effects of the utility model are: solved existing common diamond disc life-span weak point, matrix is yielding, deficiencies such as cutting efficiency is low and defective, a kind of good looking appearance is provided, sturdy and durable, cut sharply, matrix is easy damaged, distortion not, the fan-shaped high tooth diamond disc of sintered type that life-span is long can be used for the cutting processing of various stone materials.
