 The adjacent photo shows the cell set for form tapping (6) M3 x .5 holes in a stamped base plate . No clamps are required since multiple tools are engaged in the part at the same time. A coolant disbursement system is applied that controls the amount of coolant sprayed on the tool and at what interval (every other part, etc.) Fixtures and taps are changed over and the machine set to tap one of the other style parts, in less than one minute. Tap cycle time is 7 seconds.
 Two of the fixtures supplied for the set of three stampings, are multi-station. In turn, different sides of the stampings are oriented for tapping at each station. In one case, shown at right, two different size and pitch threads are tapped. The part is positioned at the left hand station for tapping (3) M6 x 1 holes and at the right hand station for (2) M3 x .5 holes. In turn, the two different tap cycles are sequential and a part is tapped at only the left or right hand station at any one time. The machine automatically changes from 1 to .5 metric pitch tapping in between the two cycles and detects which station has a part in it and that the correct handling sequence has been followed.
 The machine features a Zagar standard MQ150 ball screw unit which is shown in this photo. The feed axis AC servo motor is toward the right. The spindle axis servo is at the left. Baldor standard AC servos, amplifiers, and 2 axis, CNC motion controller are applied. The feed axis motor is 32 lb. in. cont. stall torque and the spindle motor, 126 lb. in with a max. 3:1 pulley ratio to the spindle. Zagar’s larger MQ60-140 ball screw units feature maximum 10HP spindle motors. The system drills, rigid taps, or drills & taps in a combined cycle (drapping) as a standard.
