In F37 collets (DIN 1536E, TF37 Collet, EF37 Collet, E1536), the d dimension is 37 millimeters. This collet gets its name from this dimension. The A dimension is 47 millimeters and the B dimension is 40 millimeters. The K angle is 16 degrees.
As Erveysa, we grind the above-mentioned dimensions precisely. Again, we grind the inner diameter dimension, which is the diameter that holds the material, precisely.
F37 collet (DIN 1536E, TF37 Collet, EF37 Collet, E1536) is ground with a precision of 0.01 mm in diameter 10 millimeters.
In our ultra-precise collet production, we produce with a precision of 0.008 mm in diameter 10 mm.
