  • PCNC 1100: The Leader in Small CNC Milling Machines

    The Tormach PCNC 1100 personal CNC mill is a new approach in CNC milling machines – a small CNC mill designed for real work with the power to cut serious materials. Milling circuit boards, aluminum, and engineering polymers are a breeze when your CNC milling machine is built to cut materials like steel, iron, stainless, and titanium.

    PCNC 1100 personal CNC mills were engineered from the ground up to be the best value in small CNC milling machines. The Tormach PCNC 1100 personal CNC mill was thoughtfully designed with a combination of quality components and proven technology to create an affordable small CNC milling machine that provides unprecedented value in CNC mills.

    Design Elements: PCNC 1100 CNC Mill

    Iron and Frame Design

    Each PCNC 1100 CNC mill has over half a ton of cast iron and steel that is precisely placed to achieve maximum frame rigidity in a footprint that's about the size of a traditional manual milling machine.

    The sliding dovetailed ways are hand-scraped and designed to withstand high loads and dampen vibrations. The ways have bonded PTFE filled acetyl sliding surfaces, hand scraped by skilled machine builders. Similar to brand name compounds such as Turcite® or Rulon®, PTFE compounds provide low friction and long life.

    Spindle System

    Each PCNC 1100 small CNC mill features an R8 spindle with a 3 3/8" nose diameter - the same standard dimension as 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.

    The CNC milling machine spindle is driven by a robust 1.5HP induction motor powered by state-of-the art sensorless vector variable frequency drive technology from Emerson Control Techniques™. The drive's quick acceleration/deceleration provides a responsive spindle with the capability to meet demanding processes such as tension-compression tapping. Power transmission is accomplished with a simple, low–maintenance belt driven induction motor with two belt ratios, covering speeds from 100-5120 RPM.

    Tormach PCNC 1100 personal CNC mills also feature our exclusive fold backspindle logic. Fold back logic senses when the spindle motor is having difficulty maintaining the programmed speed due to excessive cutting loads and reduces the commanded motor speed temporarily, if necessary, to maintain adequate cutting torque. Its analogous to an automatic transmission dropping into low gear on a hill.

    Motion System

    Motion control is provided by high performance polyphase stepper motors with microstepping driver technology from Leadshine®. These drive systems not only provide superior torque at cutting speeds, but improved linearity, reduced vibration, and quieter operation when compared to other stepper systems available today. Each axis uses a P4 precision ground double-nutted ballscrew for repeatable and accurate motion resolution.

  • PCNC Mills FAQs

    1. What are the dimensions/footprint of the PCNC Mills?

      The PCNC 770 with the Deluxe Stand is roughly 61" x 45" x 73" - with the Full Enclosure it is 61" x 53" x 78". The PCNC 1100 with the Deluxe Stand is roughly 80" x 45" x 82" - with the Full Enclosure it is 80" x 54" x 87". Check our Document Library for PDF drawings of the machine dimensions.

    2. Can the PCNC mills be taken apart to move in pieces?

      This is certainly possible and quite a few people have done just that. All castings are pinned with precision ground dowel pins to allow disassembly and reassembly while preserving the alignment of components. Nevertheless, you do need to be careful to avoid damaging the precision surfaces. In particular, The PCNC 770 is designed for disassembly into 3 subcomponents. This not only makes lifting more manageable, but allows transport of the mill into smaller spaces, such as basement shops. For more information on the PCNC Moving Kit, visit our PCNC 770 webpage or related blog post.

    3. Why is the PCNC rated for "short run production"?

      The reason we mention short run production is that we want people to be realistic about the commercial application of a 1.5 hp mill. If you typically have to make 10,000 parts in a run then you probably need a different machine. The reference to short run production does not imply any limitation in durability or duty cycle. The PCNC mills can be run continuously, 24 hours a day. We know of complex mold making or engraving tasks where our customers are running 16 hour programs. That being said, a PCNC mill can be fitted with several options to boost productivity. These include a pneumatically actuated power draw bar and a 10 position automatic tool changer (ATC).

    4. Are the PCNC mills suitable for commercial work?

      Absolutely. Most machines are used in small shops for prototyping and specialty produciton. Quite a few are running continuously in multiple shift operations. The mills get their hardest workout when used as part of a dedicated work cell in a production environment. In this capacity, Tormach machines have been used as dedicated mill/drill machines, plunge EDM electrode mills, or even portable secondary operation stations. System integrators have even used our mills as a custom motion platform for some very unique applications. For examples of Tormach customers using their PCNCs for commercial work, visit our Customer Showcase webpage.

    5. What motion control is used on Tormach PCNC Mills?

      Tormach Mills and Lathes alike run on PathPilot - The Next Generation of Tormach Motion Control.

    6. How loud are Tormach PCNC Mills?

      There has never been an official decibel reading done on the machines because the sound level we hear may not be the sound level you hear. There are too many factors that determine sound: use of enclosure, material being cut, speeds, feeds, depths of cut, size of room, etc.
