Tormach PCNC1100 - CNC milling machine

The Tormach CNC Milling Machine lives in the machine shop, but it is currently managed by its own Resource Manager.

Resource Manager: Steve Richardson

We took delivery of our Tormach PCNC1100 on April 1, 2016.  This machine requires extensive training and is not open to general member use without completion of classes and a training period.

The first round of classes began in October, 2016 for a total of thirteen weeks.  This includes the following classes (2-3hrs each class):

  • Fusion 360 CAD (4 weeks) - learn to model parts using Autodesk Fusion 360 CAD
  • Design for Machining (1 week) - learn how to design parts that you can actually make using our equipment
  • Fusion 360 CAM (4 weeks) - learn how to take your CAD model, program machining operations, and ultimately produce G-Code suitable for running on the Tormach machine, using Fusion 360 CAM.
  • Tormach PCNC1100 Training (4 weeks) - Including two weeks of instructional material and live demos about safe and proper operation of the Tormach machine, and a hands-on project carried on from the CAM class.  Students will get individual hands-on time to ultimately make an aluminum keychain bottle opener on the Tormach CNC.
Once students have completed these classes, they are considered beginner operators and may work on their own projects to be run on the Tormach only under supervision of an advanced operator or the class instructor.  Once beginner operators have proven their knowledge with a few projects, they will become advanced operators and can run their own projects and also supervise beginners and share their knowledge.

Here are the basic machine specs:
  • 34" x 9.5" table, with a 18" x 9.5" x 16.25" (X,Y,Z) work envelope
  • Stepper motor driven axis movement, XY motion rapids 110IPM max, Z motion rapids 90IPM max
  • R8 spindle, driven by 1.5HP 3-phase AC induction motor and Emerson VFD.  Belt-driven with two ranges: 100-2500RPM, 200-5100RPM
  • Optional flood coolant
  • Chip/coolant guards, chip/coolant drain pan
  • PC-based CNC control via PathPilot software (which is based on LinuxCNC)
We have the following accessories and tooling available for exclusive use with this machine:
