Revolver Lathe Collets
Revolver, index, mechanical automatic, and CNC automatic collets; referred to as A15, A20, A25, 25 INDEX, A30, 36 TRAUB, A42, and A60, are also named according to the following standards:
140 E, 148 E, 161 E, 162 E, 163 E, 171 E, 173 E, 185 E.
The F Codes for these products are as follows:
F22 (140 E), F28 (148 E), F32 (161 E), F35 (163 E), F42 (171 E), F48 (173 E), F66 (185 E).
These collets are named according to the ground sections on the back. The material selection and the heat treatments applied to these materials are very influential on the performance and lifespan of the collets. Main spindle collets should have a groove inside to hold the material better. Sub spindle collets, used to hold machined materials, should be groove-free to avoid damaging the material. However, main spindle collets can also be groove-free for smaller diameters. Different designs can be produced for materials requiring precise surface machining. For high-volume production and products with high surface wear, carbide can be welded inside the collets. However, if these collets are struck, the carbide can be damaged. Coating can be applied inside the collets to increase durability and surface quality.
Revolver collet – F66 – DIN 185E
Erveysa collets are produced to high standards by applying global standards.
F66 (DIN 185 E) is also referred to with standards A60 and 76-359. In the Turkish market, it is also called „60 head collet.“
The name F66 collet derives from the d dimension being 66mm. The L dimension of this collet is 110mm, and the A dimension is 84mm.
The name F48 (DIN 173 E, A42) collet derives from the d dimension being 48mm. The L dimension of this collet is 94mm, and the A dimension is 60mm.
The name F42, DIN 171 E, 36 TRAUB collet derives from the d dimension being 42mm. The L dimension is 94mm, and the A dimension is 55mm.
The name F35, DIN 163E, A30 collet derives from the d dimension being 35mm.
