The standard US spindle shaft is 1 + 3 ⁄ 4 in (44 mm), with 3 ⁄ 4 or 1 ⁄ 2 in (19 or 13 mm) on small shapers and 30 mm on European models. Most spindles are tall enough to accommodate more than one cutter head, allowing rapid tooling changes by raising or lowering desired heads into position. Additional spindles can be fitted with pre ...

SFM is a combination of diameter and the velocity of the material measured in feet-per-minute as the spindle of a milling machine or lathe. 1 SFM equals 0.00508 surface meter per second (meter per second, or m/s, is the SI unit of speed). The faster the spindle turns, and/or the larger the diameter, the higher the SFM.

A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles.
HSK's hollow shank is deliberately thin and flexible, so it expands more than the spindle and tightens when rotating at high speed. Furthermore, the HSK holder is dual contact: It engages with the spindle on both the taper and the top of the flange which resists axial movement when thermal growth and/or centrifugal force of the spindle occurs.
