The shape code of a diamond grinding wheel generally consists of three parts: the first part of the chart indicates the series of grinding wheel shapes, indicated by a unit number or double digits; The second part indicates the cross-sectional shape of the work layer, indicated by one or more letters; The third part indicates the location of the operation layer, expressed in one unit. For example, the code 6A2 indicates that it is a parallel grinding wheel series, A indicates that the cross-sectional shape of the working layer is rectangular, and 2 indicates that the working layer is on one side of the grinding wheel.
The following is an introduction to the meanings of the codes for each part:
1、 Meaning of grinding wheel shape code
1 parallel system
2 cylindrical shapes
4 monoclinic
6 hollow cylindrical, cup-shaped, single-sided concave
9 Double sided concave
11 bowl shaped
12 disc shaped
14 Parallel reinforced shape, double oblique shape
2、 Meaning of cross-section shape code for operation layer
A rectangle
B Triangle
D trapezoidal shape
DD Two trapezoidal shapes
E dovetail shape
EE Double Dovetail
EEA double dovetail with rectangular shape
F circular arc
FF double circular arc
L rectangular fillet
V parallelogram
3、 Meaning of operating layer orientation code
1 at both ends
2 on one side
3 on both sides
6 embedded matrix
8 without substrate
9 on both sides of a bowl shaped cup or dish
