The material portion located between the cutting grooves is easily broken to a large size by rubfriction or rotational impact of a non-diamond portion of the tool.

Description

Diamond tool with segment type cutting tip {DIAMOND BLADE HAVING SEGMENT TYPE CUTTING TIP}

The present invention relates to diamond tools for use in devices such as cutting saw machines, grinding wheel machines, or core drilling machines for cutting, grinding, and drilling brittle materials such as marble, granite, concrete, brick, etc., respectively. In particular, by arranging at least two diamond layers according to the direction of rotation of the tool to form at least two fine straight cutting grooves by the diamond layer during the cutting operation of the tool, the portion of the material located between the cutting grooves The present invention relates to a diamond tool having a segment type cutting tip composed of a plurality of diamond layer segments that can be easily broken into a relatively large size by friction or rotational impact of a non-diamond portion of the tool to increase the cutting force of the tool.

Conventional diamond tools or blades 1 for use in devices for grinding or cutting brittle materials such as cutting saw machines, as shown in Figs. A steel wheel body 2 connected to the shaft of the electric motor having a plurality of discharge slots 3 for a plurality of cutting segments 4 fixedly attached between the discharge slots 3 at the outer circumference of the wheel body 2. It is composed.

The cutting segment 4 is made by mixing the powder of diamond and abrasive, powder of metal such as cobalt, nickel, bronze, copper, powder such as ceramic, resin and the like and plastically processing it to a certain shape.

Therefore, the diamond powder 8 is randomly distributed inside and on the surface of the cutting segment 4, as shown in FIG. 3A.

In this blade 1, the upper surface of each cutting segment 4 is cut into the material 5 by contacting and polishing with the corresponding surface portion of the material 5 to be cut in the cutting operation, as shown in FIG. 3B. The slot 6 is formed.

Cutting chips generated during the cutting operation of the cutting segment 4 are collected in the discharge slot 3 and the cutting slot 6 of the steel wheel body 2, and the discharge slot 3 of the steel wheel body 2 is steel When moved from the inside of the cutting slot 6 to the outside by the rotation of the wheel body 2, it is discharged to the outside.
