ABSTRACT:
A tapping lubricant dispenser apparatus is provided for use in numerically controlled automatic toolchanger machining systems to dispense tapping lubricant into a previously drilled hole before tapping. The tapping lubricant is usually a viscous tapping compound of the consistency of paste, grease or the like. The apparatus includes a toolholder of the type to fit into the machine spindle, a reservoir for a supply of lubricant--typically sufficient to run unattended for several complete cycles, e.g. at least one shift--and a reciprocating pump that dispenses the lubricant responsive to actuation by the numerical control system when the toolholder of this apparatus is fitted into the machine tool spindle. The reservoir reloads the pump after each dispensing action. The numerical control and toolchanger system is programmed to select the apparatus, put it in the spindle, align same with the hole to be tapped, and causes pump reciprocation and dispensing and then remove the apparatus from the spindle. Usually a drilling program is employed whereby the motion to advance the drill into a hole instead advances this apparatus thereby placing in the hole a body of lubricant.
