Special Collets for Small Parts
Precision collets for small and miniature parts, with runout tolerance of ≤ 0.003 mm for medical and watchmaking work.
Description
Product Overview
Special collets for small parts are precision workholding tools designed for clamping and machining very small components with diameters of a few millimetres or even below 1 mm. These collets provide close clamping tolerance, accurate concentricity and minimal runout.
Medical manufacturing, Swiss watchmaking, precision electronics and dental manufacturing are among the main users of these collets, where small-diameter parts must be held securely with close dimensional accuracy.
