Basic Information
- The Tormach was donated by Autodesk
- Tormach PCNC 1100 tech specs
- Resolution: 1 tenth / 0.0001" / 2.54 micron / 1.26262e-8 furlongs
- 1.5HP, 100 to 5140 RPM (two speeds, belt adjust)
- Feed Rate: 110 IPM (X,Y) 90 IPM (Z)
- Fixture plate: Grid of M10 threaded holes (Warning! This is not the same size as our mill clamping kit! Do not force those studs into the Tormach plate! The mill kit uses 3/8-16 threads)
- TODO create 3D model
- TODO buy holder clamp set
Usage & Safety
The milling machine is both a precision machine and also powerful enough to seriously hurt you. It needs to be treated with the same respect you would give any precision tool. All members are welcome to use the machine after being shown how to use it properly.
- Only trained members may use this machine.
- Tie back long hair, remove long sleeved shirts and jewelry.
- Eye protection must be worn when machine is running.
- Check all tooling and machine for damage before using.
- Sweep / vacuum up chips and leave the machine clean.
- No unconventional / unsafe use.
- Usage on non-metals requires your own tools.
- No hammering on the machine table. It is high precision!
- You break it, you buy it!
You MUST be trained before using this machine. Please consult a member who knows what they are doing. You can help a guest with a job but guests are not permitted to use the machine themselves.
Note that knowing how to use a milling machine is not sufficient - You must be shown by a trained member the intricacies of our machine.
Coolant Coolant to water concentration must be checked at [SCHEDULE] | Portable refractometer instructions
Tank capacity: 6.5 Gallons / 24L Coolant must be:
- Biodegradable
- Synthetic
- Water based
- NO OIL
- Should be compatible with both ferrous metals and aluminum.
Recommended: "xtreme cut 250" from torontolube.ca

Enclosure
Tool Setter

- The trigger height of the ETS is 80 mm
- TODO
Work Probe
4th Axis The Tormach has an 8" three-jaw chuck, normally mounted as an "A" (along "X") axis. It could also be rotated to be vertical for the "C" axis (along "Z").

- https://tormach.com/adjustable-tailstock-tall-30197.html
- TODO
Preventative Maintenance
- DAILY
- Way oiler - pull out one full stroke before each use, and again every 4 hours of runtime
- Air oiler - check for oil (behind the machine)
- Check coolant level
- Remove chips from ways, carriage and bellows
- Long-term
- Check coolant concentration; remove sediment
- Check axes are receiving oil, check belts
CNC Controller
- Uses PathPilot (based on LinuxCNC)
- TODO
Tool Holder
- TTS - Tormach Tooling System
Flood Coolant
Qualichem XTREME CUT 250C
