Tormach LLC is proud to announce the Personal CNC 1100. Three years in development, the PCNC 1100 is a small CNC vertical mill offering unprecedented value in a precision machine tool. Priced at $6800, the machine has design features normally seen on machines costing $15,000 or more.

• Table Size – 31.5" x 9.5"
• Spindle Center to Column Face - 11"
• Weight 1130 lbs net / 1296 lbs shipping
• Max spindle nose to table - 17"
• Spindle Speed Range RPM - 300-4500. Completely integrated for computer controlled spindle speed and direction with DC injection braking allows floating tap operations, or manual operation. The mill features a cartridge style spindle based on quiet and efficient V-belt transmission. There are two overlapping speed ranges. Low belt speed is 300 – 1750 RPM, high belt is 800 – 4500 RPM.
• Main spindle power 1.5 HP (1100 Watts).
• Spindle safety is enhanced with a tool change safety interlock, and key switch lockout. Main spindle contactor (VFD power) is automatically disengaged when operator is changing a tool. Spindle M codes or manual spindle start will re-engage VFD power automatically after tool change is completed.
• Power requirements - 220 VAC single phase (110 VAC option)
• Forward opening electrical cabinet. This unique design allows service even when the machine is placed against a wall.
• Rapid traverse X, Y, Z - 65 IPM
• NEMA 34 stepper motors on X, Y, and Z
• 15 point lubrication. Each axis has an oil distribution channel milled full length on left and right vertical and horizontal surfaces (all 4 sliding surfaces) plus an oil line plumbed directly to the ball nut assembly. That’s 5 points per axis, 15 total lubrication points.
• Precision ground ball screws in the X, Y, and Z motion. Rolled ball screws are typically ISO/DIN T7 grade, also known as C7, and are designed for transport mechanisms such as aircraft elevators. We use P5 grade, designed for precision applications. P5 has approximately ½ the allowable error than T7.
• Double nut technique is used for anti-backlash ball screws. This is more expensive than the oversized ball technique, but provides for significantly longer life.
• Complete way covers, no exposed ways or ball screws.
• Iron castings, more than half a ton of iron.
• Slide ways are have a bonded low friction surface (PTFE filled acetal). Similar to brand name compounds such as Turcite, Rulon, and Delron AF, PTFE compounds provide low friction and long life. The dynamic coefficient of friction is the same as the static coefficient of friction, thus eliminating stiction (slip – stick) action.
• Digitizing & tool touch off port, optically isolated.
• Coolant or accessory AC outlet. The AC outlet for coolant is automatically controlled via M codes while the operator console offers a convenient manual over ride.
• PC or accessory AC outlets, manually controlled on the operator console.
• Complete RS-274 (G & M codes) implementation with unlimited program size. Conventional G&M code operations are complimented with manual mode operations, operation wizards, DXF drawing support, HPGL, bitmap, and jpeg toolpath generation. Operation wizards allow pocketing, surfacing, cutouts, drill patterns, and other standard operations to be completed without the need for addition software or manual code writing.
• Preconfigured for low cost 4th axis addition. Software support, wiring, cabinet holes, and drive mount holes are all in place for an easy 4th axis addition.
• Modular Design, Open Architecture
• All electronics are USA designed & manufactured
• 200 page operators manual.
• 6 month warranty. There is no on-site factory service personal. Warranty service will involve replacement of components with direction

Summary

Designed specifically for short run and prototyping applications, the PCNC 1100 addresses the needs of research, development, education, and short run production. The open architecture design combines proven cast iron construction with personal computer technology to provide exceptional value, ease of use, performance, and long term value. The machine is fully capable of cutting iron, steel, titanium, and even nickel based alloys like 300 or 400 series stainless. Tormach has partnered with a manufacturer that has considerable experience in the production of larger CNC machinery for the Chinese market. The machine is manufactured in an ISO 9001 factory. All electronics are manufactured in the USA and then shipped to China for final assembly. The machine design has been qualified using an Optodyne Laser Doppler Displacement Meter with 0.0001 mm (0.0000039”) resolution.

Attached files include:

1) Photograph of the machine.

2) Solidworks image of machine turned upside down, showing massive ribbing. The holes through the base are used to insert a rod, allowing the machine to be lifted using the forks of a lift truck.

3) Solidworks image with transparent spindle cover, showing motor, cartridge spindle design, and other details. We put a lot of thought into this design.

4) Solidworks image with spindle cover removed. Highlight in green is spindle motor lock, spindle motor swivel handle, and spindle rotation lock. Belt speed change takes about 15 seconds. Also note on the back of the column is a convienient eye bolt for lifting the machine.

Images are file attachements. I don't know how to embed them in this message.

looks a lot like pieces of a grizzly minimill?

[miljnor]

I like it! nicely done.

hopefully someone here will purchase one and give us a non-biased review.

anyone? .....

looks a lot like pieces of a grizzly minimill?

Good grief! Exactly what of this machine looks like pieces of anything else?

The machine is totally original, from the ground up. We had several design reviews before casting parts for the original prototype. There were several generations of machines built since then, each with new castings. Three years ago we considered trying to make a CNC machine as a derivation of something that was already being manufactured, but we found the compromises would be greater than we could accept.
