HOW TO TAP USING THE TORMACH PCNC 1100 MILLING MACHINE

Only the newest Tormach CNC milling machines offer rigid tapping, therefore a floating tapping head must be used with most Tormach PCNC milling machines. The tapping head allows for a small amount of compression and tension. Tormach sells a few different floating tapping head solutions, one of which has a clutch.

• TORMACH TTS™ ER Collet Tap Holder: ER16 - $189.00

• TORMACH TTS™ ER Collet Tap Holder: ER20 - $189.00

• Modular Tension/Compression Tapping Head Kit - $459.95 - This is an expensive set but has quick change collets of different sizes and adjustable slip.

iCarbide sells their own TTS-compatible version for a lot less expensive.

• ATC3/4 STRAIGHT SHANK ER20 TAPPING TOOL HOLDER LENGTH L 3.14" FOR TURNING - $69.00

• ATC3/4 STRAIGHT SHANK ER16 TAPPING TOOL HOLDER LENGTH L 3.14" FOR TURNING - $69.00

Tormach PCNC 1100 Series 3 Z Axis Brake

The Z axis brake on the Tormach PCNC 1100 Series 3 Milling Machine is energized using 60V DC. I measured that with a voltmeter.

I accidentally purchased a Tormach 1100M Z axis motor, which has a 24V brake. A step down converter is required to run this brake from the PCNC 1100 Series board.
