Personal CNC 770 Specifications
The PCNC 770 utilizes the same proven design principles as Tormach's industry leading PCNC 1100 Series II mill, but in a space economizing smaller package. Each mill is built from over 650 lbs. of cast iron and steel that is precisely placed to achieve maximum frame rigidity while still maintaining a size and shape that's manageable in the small shop or lab.

Each mill features a R8 spindle with a 3 3/8" nose diameter that is common to popular Bridgeport -style manual mills. This can be used in combination with the innovative quick-change Tormach Tooling System® (TTS) or any generic R8 tooling.

Motion control is provided by high performance stepper motors with microstepping drivers. The stepper motors drive the same precision ground P4 grade ball screws used on the PCNC 1100 Series II, giving each axis repeatable and accurate motion resolution.

The sliding dovetailed ways are hand-scraped cast iron, designed to withstand high loads and dampen vibrations. The ways have bonded PTFE filled acetal surfaces. Similar to brand name compounds such as Turcite® or Rulon®, PTFE compounds provide low friction and long life. And unlike other small footprint mills, the PCNC 770 has tapered gibs instead of an inferior plate and set screw design.

With the PCNC 770, we have again chosen state-of-the-art sensorless vector technology in the spindle drive, providing exceptional speed and torque characteristics. The drive's quick acceleration/deceleration improves performance while extending capabilities to demanding processes such as tension-compression tapping. The spindle uses a simple, low –maintenance belt driven induction motor with two belt ratios. The spindle drive provides infinite speed control of 175 to 3250 RPM in the low ratio, and 525 to 10000 RPM in the high ratio to cover your needs from tapping to finishing.

As with all Tormach products, The PCNC 770 is backed with Tormach's second-to-none customer care and technical support to ensure your satisfaction. We will support your investment with email and phone support from our dedicated support of machinists and engineers and extensive online resources so you can rest assured that you made the right choice from day one.
