Marking of carbide plates
DESCRIPTION OF THE CHARACTERISTICS OF CARBIDE PLATES
Plate shape
Shape пластины can vary widely from diamond-shaped with an angle at the top of the plate 35 ° to round. And each of them has certain properties. Some plates provide the best patency during profile processing, while others provide maximum strength during roughing.

Accuracy class
It implies tolerances for the dimensions of the theoretical diameter of the circle inscribed in the plate, thickness and other parameters. The tolerances are valid for plates prior to edge preparation and coating.
Design features of the plate
Describes the shape of the plate. Whether it has a mounting hole or not, a one-sided or two-sided plate, whether there is a chip-breaking geometry or not.
Size/thickness/radius
The numbers in the marking are encrypted:
-
the first pair of digits is the length of the cutting edge
-
the second pair of digits is the thickness of the plate
-
the third pair of digits is the radius of rounding at the top of the plate
Additional designations
Additionally, the types of plate execution (right, left or neutral), as well as the parameters of the cutting edge (sharp, rounded, chamfered or combinations thereof) can be specified.
Chip breaker
Marking of chip-breaking geometries is unique for each manufacturer. When choosing, you need to focus on the recommendations of the catalog.
