M vs MX - What Is The Difference?

• SPEED:
  Rapid Speeds - 1100MX and 770MX boast 300 inches per minute (IPM) rapid speeds, while PCNC and M series machines boast rapid speeds of 110-135 (IPM).
  Cycle Times - Generally speaking, the MX machines have 20% faster cycle times (varies based on tool path and part geometry).
• MOTION CONTROL:
  Stepper Drive Motors - Stepper motors have no positional feedback loop. When the controller tells an axis to move, it’s assumed the motor in fact moves that much. The only time you are in real danger of losing position with a stepper motor in our machines is if you crash or stall your machine.
  Servo Drive Motors - Servo motors provide positional feedback. When the controller calls for an axis to move, then the motor sends positional feedback, verifying it’s where it should be. This allows for crash detection, much higher rapid speeds and more accurate homing. See machine specs for the speed capabilities of each machine.
• SPINDLE:
  BT30 - MX machines have a BT30 spindle, which is an industry-standard tapered tool holder with a 45 degree pull stud and drive dogs. This combination allows for a more rigid connection between the spindle and the tool and reducing the risk of tool pull-out. In addition, this is an encoded spindle, giving the controller awareness of position, allowing for rigid tapping.
  TTS - PCNC and M machines have an R8 collet in the spindle and use TTS tool holders. This is a 3/4” straight shank tool holder that is proprietary to Tormach.
