The shaft, mandrel, or arbor, in a machine tool, as a lathe or drilling machine, etc., which causes the work to revolve, or carries a tool or center, etc.

A shaft or pipe on which a core of sand is formed.

Component in the Motor/Base Module of a rotary system, which couples the motor shaft to the piston. The spindle contains a spherical bearing which accepts the piston drive pin.

This refers to the centerpiece of a hard drive which holds one or more hard drive platters. Often, the term spindle is used to differentiate hard drives from hard disk platters in discussion when referring to large RAID subsystems holding many hard drives, such as "We'll be using 50 spindles instead of 10 spindles in the new RAID box." Basically, a spindle is seen as a limiting factor in performance. Generally, more spindles in a system mean higher possible performance.

The long, round, slender rod or pin in spinning wheels by which the thread is twisted, and on which, when twisted, it is wound; also, the pin on which the bobbin is held in a spinning machine, or in the shuttle of a loom.

A slender rod or pin on which anything turns; an axis; as, the spindle of a vane.

The vertical rod on which the runner of a grinding mill turns.

A long and slender stalk resembling a spindle.

contains fibers which form a network of achromatic filaments that extend inward from the poles of a dividing cell, forming a spindle-shaped figure. They move the centromeres around, causing the rest of each chromosome to follow. This process ensures that each chromosome moves to its proper place during mitosis, when a cell divides to give rise to two cells, and during meiosis, the process of cell division that gives rise to eggs or sperm.

The set of tubulin fibers that appear to move eukaryotic chromosomes during division. The microtubule apparatus that controls chromosome movement during mitosis and meiosis.

(biology) tiny fibers that are seen in cell division; the fibers radiate from two poles and meet at the equator in the middle; "chromosomes are distributed by spindles in mitosis and meiosis"

A network of fibrous microtubules and associated molecules formed during mitosis between the opposite poles (centromeres) of eukaryotic cells. It mediates the movement of the duplicated chromosomes to opposite poles.

a woodworking machine rotating on a vertical axis in which shaped cutters are mounted for cutting mouldings, rebates and similar features in wood

a device used to hold the tags gathered at the end of the processing chutes, in their proper sequence.

A spindle is the part of a CNC Milling machine that holds the cutters and spins at speeds of up to 12000 RPM s. Due to the presence of the spindle, some cuts - particularly very deep and narrow cuts - require special set-ups and attention.

The threaded arbor on a shaper that holds the cutters.
