4 interchangeability
4.1 Tolerance
According to ISO 1832, the carbide indexable inserts mentioned in this standard provide the following tolerance levels.
a) 0°, 11° back angle inserts (TP, SN and SP). The tolerance grades are divided into A grade, C grade, K grade, of which grade C is mainly used for coating.
blade;
b) 20° back angle insert (TE, SE). tolerance class C.
Appendix A gives these tolerance values in accordance with ISO 1832. For other tolerances, see the drawings and tables for the blade dimensions in Chapter 7.
4.2 Size m
The m value specified in this standard is the theoretical value. In fact, due to the different manufacturing and inspection positions of the blades, different manufacturers will guide
The size of the m value varies within ±0.05 mm. For the same blade manufacturer, the m value shall be implemented in accordance with ISO 1832 (see
Appendix A).

Method of detecting m value
B.1 triangular blade
The m value is measured by the same standard cylinder with the same diameter as the inscribed circle of the insert. Placed on a standard cylinder as shown in Figure B.1
A block gauge with a size equal to the m value, calibrate the dial gauge to zero position, then place the blade in a 60° V block, and the dial gauge will accurately measure the knife
The m-value deviation of the sheet, the diameter deviation of the standard cylinder is ±0.002 mm.
Figure B.1
B.2 square blade
The m value is measured by the same standard cylinder with the same diameter as the inscribed circle of the insert. The main declination is 75° as shown in view B.2a)
The blade with the lead angle shown in Figure B.2b) is a 45° blade. When measuring, place a block gauge with the size equal to the m value on the standard cylinder and calibrate the dial gauge to zero.
Position, then place the blade on the 90° V block, the dial gauge will accurately measure the m value deviation of the blade, and the diameter deviation of the standard cylinder is
±0.002mm.
a) b)
Figure B.2
The three-point positioning of the blade is used when measuring the m value using the block. Two of the points should form an angle φ with the back corner of the wiper
The flank of a blade edge.
