PCNC 1100 Series 3 CNC Mill

Technical Overview

The PCNC 1100 Series 3 is the third generation of our best-selling small CNC mill. From the beginning, the PCNC 1100 was developed as an affordable, easy-to-use CNC Mill for engineers, designers, inventors, technicians, hobbyists, educators, and specialty/short-run manufacturers. Each PCNC 1100 combines quality components with thoughtful engineering and Tormach's best-in-class technical support to provide the best value in CNC milling.

PCNC 1100 CNC Mill Design Considerations:

• Affordable Precision - achieved by a combination of dynamic stiffness and motion resolution. An engineered frame provides maximum stiffness/weight ratio. Direct-drive anti-backlash ballscrews coupled to a precision microstepping drive system provide best-in-class motion resolution.
• Capability to Cut any Material – from plastic and aluminum to stainless and pre-hardened steel. A Robust 1.5hp spindle design with digital drive electronics provides both the speed range and torque characteristics to tackle any job, no matter the material.
• Expandable, Modular Design – add accessories like 4th Axis, Automatic Tool Changer, Power Draw Bar as needed. PCNC 1100 CNC Mills are designed to grow with your business and interests.
• Low cost of Ownership – a well executed, but simple design means your PCNC 1100 CNC Mill is easy to maintain and affordable to run. Its built for the rigors of daily use, but affordable as an occasional, at-the-ready CNC milling capability.

New Features: PCNC 1100 Series 3 CNC Mill

For the PCNC 1100 Series 3, we introduced a completely revamped axis motion system that combines high performance polyphase motors with state-of-the-art Leadshine® microstepping drive electronics. As a result, the PCNC 1100 Series 3 CNC Mill provides increased torque at cutting speeds, faster motion maximums, and ultra-quiet performance over previous generations of Tormach CNC Milling machines.

Polyphase Motion Provides:

• Increased maximum motion speeds
• Significant Improved Torque at Cutting Speeds
• Lower Noise
• Improved Accuracy
• Improved Linearity
• Reduced Vibration

For more information about the benefits of polyphase motion, refer to our Series 3 Design Analysis Whitepaper

Additional New Feature: PCNC 1100 Series 3 CNC Mill

Redesigned Operator Console:

Based on customer feedback, we've reorganized the buttons into functional groupings for better work flow and utility.

New Paint Formulation:

PCNC 1100 personal CNC milling machines are now painted with a long lasting 2-part acrylic alkyd-amino resin system that adheres tightly and is resistant to most cutting fluids and oils.

Cast Iron Tool Tray:

A popular feature that first appeared on our smaller PCNC 770 personal CNC milling machines is now standard on all PCNC 1100 personal CNC mills, providing a convenient place to set wrenches, clamps and other hand tools.
