Multiple Spindle Tapping:
Multiple spindles are the fastest manufacturing method for tapping multiple holes in mass produced parts. 22 Holes ranging in size from # 4-48 to ½- 20, are tapped each cycle by this machine that was recently built by Zagar Inc. in Cleveland, Ohio. All 22 holes are tapped in less than 4 seconds. That's less than two tenths of a second per hole. Work pieces are 12 gage steel stampings. 11 Holes are tapped at each of 2 adjacent stations. The parts are sequenced thru the stations to complete the 22 hole pattern. Taps range in size from a # 4 to one half inch. Pitches range from 48 threads per inch to 13 threads per inch. Each tap is driven by an individual lead screw. In turn, the pitch of each lead screw matches the pitch of the tap being driven.
Multiple Spindle Drill:
The 22 spindles are driven by a Zagar gearless multiple spindle tapping head. All 22 spindles are mechanically synchronized to each other. Each rotates the exact same number of revolutions and at the same time. The number of revolutions or length of travel, is adjusted with control collars on a separate lead screw that is monitored by proximity sensors. This permanently maintains an accurate full-depth position of each tap without adjustments thru years of production cycling. In turn, Zagar individual lead screw tapping is applied to thru holes, blind holes, or gauged diameters of tapered tapped holes (pipe threads).
