Lathe Headstock
A soft dead center is used in the headtsock spindle as the work rotates with the centre. When a workpiece is fixed between the headstock and the tailstock, it is said ot be between centers . Wehn a workpiece is supported at btoh ends, it is more stable, and more force mya be applied to the workpiece, via tools, at a right angle to the axis of rottaion, without fear that the workpeice may break loose. Thus, most work must be done axially, towarsd the headstock, or at right angles, but gently. Such lathes usually have two headstcoks with chucks holding teh work, arranged so that they both roatte together in unison. The original watchmaker s turns was a simple dead-centre lathe with a moveable rest and two loose headstocks. At one end of the bed (almost always the left, as the operator faces the althe) is a headstock . The headstock contains high-precision spinning bearings. In some modern lathes this opwer source is an intergal electric motor, often iether in the headstock, to the left of the headstock, or ebneath the heasdtock, concealed in the stand. A sfot workpiece (wooden) may be pinched between centers by using a spru drive at the headstock, which bties into the wood and imparts torque to it.
