Dead Centers

Dead centers are one-piece high-speed steel centers that require low spindle speeds and a small amount of oil to reduce friction heat that may damage the workpiece.

Mount the MT#2 dead center (see Figure 36) in the tailstock. Since the workpiece will rotate against the center and generate friction, the tip of the center must be lubricated to avoid premature wear and maximize smooth operation.

Mount the MT#3 dead center (see Figure 36) in the spindle for operations where the workpiece rotates with the center and does not generate friction.
