Diamond Scriber

Product Details

This tool is used for cutting hard and brittle materials such as compound semiconductors (gallium arsenide, gallium phosphide, indium phosphide) and sapphire. There are also types in which rough diamonds are processed into a conical shape (1-point) or 2-, 3-, 4-, or 8-point cutting edges, depending on the application. Since no grinding fluid is used, no processing facilities are required, and the narrow scribe line allows a large number of "inserts" to be taken. Chipping during breaking is less likely to occur than when using a cutter, and the optimum "point" shape can be selected.

Application

• Processing of compound semiconductors (gallium arsenide, gallium phosphide, indium phosphide), sapphire, glass, etc.

Product characteristics

(1) 1-point type (conical type) 　The 1-point scriber is a scriber with a conical tip and a radius at the leading edge. This is currently the most commonly used type.
(2) 2-point type 2-point scriber is a scriber with a flat cutting edge that leaves two points relative to the 4-point scriber and shaves off the other two relative points.
(3) 3-point type 3-point scribers are ground into a triangular pyramid with a triangular flat section at the tip.
(4) 4-point type 4-point scribers are shaped like a square weight with the tip of the square weight cut off parallel to the bottom, and the tip surface is square.
(5) 8-point type The 8-point scriber has a very thin heel point and a shape that provides a smooth line and good braking.

We manufacture various types of scribers according to the number of points. Special products (narrow angle specifications) are also available upon request.
