AutoDrill Multiple Spindle Tapping on a Pillar Drill

The customer wanted to tap three holes at a time using a typical pillar drill. Rather than using self-reversing tap heads such as the Tapmatic heads Autodrill offers, the customer chose the Grizzly G0521 self reversing pillar drill. As you can see, the process works great even at this slow, "beta test" RPM. The RPM could be increased. The multiple spindle head could be mouted to a CATxx taper and used on a CNC machine for rigid tapping... But usually it is a manually loaded tool. Reversing the pillar drill motor over and over is not suggested unless you have an inverter handling the loads, etc. Ellis makes a similar pillar drill that would work very well for this type of application in a high volume, manual production run.

This is a slow speed, very manual test with manual lubrication, etc. The process time could be significantly improved by spending more than 5 minutes setting it up.

Of course, the multiple spindle heads work wonderfully on lead screw tap machines, milling machines, pillar drills, drill presses, automatic drill machines, CNC-type machines, etc.
