Cartridge ISO 5611-11 – STWCR 12CA – 16
Steel with a tensile strength of at least 1 200 N/mm 2 .
6.1 Method of holding
(first letter symbol identifying the method of holding the insert)
6.1.1 Cartridge for indexable inserts with insert normal clearance α n = 7°
(fourth symbol identifying insert normal clearance C)
— holding screw clamping through hole; letter symbol S, e.g. SCWCR.
6.1.2 Cartridge for indexable inserts with insert normal clearance α n = 11°
(fourth symbol identifying insert normal clearance P)
— holding with top clamping; letter symbol C, e.g. CTWPR;
— holding screw clamping through hole; letter symbol S, e.g. SCWPR.
6.1.3 Cartridge for indexable inserts with insert normal clearance α n = 0°
(fourth symbol identifying insert normal clearance N)
— holding with hole clamping; letter symbol P, e.g. PTWNR.
6.2 Corner radius r ε
Cartridges in accordance with this part of ISO 5611 can be equipped with indexable inserts with cutting edge lengths l 4 as specified in Table 1 and any corner radius r ε .
The values for a, f and l 1 given in Table 1 apply to cartridges with indexable inserts having corner radii r ε in accordance with Table 2.
For cartridges with indexable inserts with corner radii other than those specified in Table 2, the dimensions of a, f and l 1 shall be determined in accordance with ISO 5611-1.
The tolerances on h 1 and f refer to dimensions measured with master indexable insert and master shim, if any.BS ISO 5611-11 pdf download.
