Lathe center

Centers are mainly used on lathes in support of long, slender components in order to reduce the deflection by the cutting forces or to avoid the risk of hitting around by unbalance.

The center point is fixed by a Morse taper rotating rigid tailstock. At the beginning of machining, the workpiece is clamped in the chuck briefly and placed with a centering lowering centrically to the rotational axis. Then, the center point is introduced by spanning the workpiece.

Live Centers are decoupled by a ball bearing and allow high speeds. Fixed centering are over precise, but cause friction. In order to avoid seizure by partial welding of surfaces separating and cooling lubricants are used. Wear -resistant carbide inserts are used.
