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.
