Desktop NC Ultra 2
Desktop 5-Axis CNC Milling Machine
Industrial five-axis control in a compact enclosed machine. Desktop NC Ultra 2 combines LNC 8250 control, EtherCAT absolute servo motors and a dedicated button panel for precision prototyping, education and small-batch manufacturing.
Overview
A compact five-axis CNC platform designed to make complex machining more accessible. The Ultra 2 integrates precision motion components, an enclosed machining workspace and an independent CNC control interface for a streamlined CAD-to-part workflow.
5-Axis Motion
XYZ linear motion with A/C rotary axes for machining complex surfaces and multi-sided parts.
Working Envelope
Effective XYZ travel of 160 × 200 × 130 mm, with dedicated 3-axis and 5-axis machining ranges.
Machining Accuracy
Five-axis spatial accuracy of <0.05 mm and linear-axis parallelism / perpendicularity of 0.02 mm.
Independent Control
LNC 8250 industrial five-axis bus controller with a 10.4-inch display and dedicated physical controls.
Key Features
Precision components and practical operation features for desktop five-axis manufacturing.
RTCP Five-Axis Control
LNC 8250 control supports RTCP five-axis workflows, with A-axis travel from −30° to 120° and 360° C-axis travel.
High-Speed Water-Cooled Spindle
The standard configuration uses an 800 W, 24,000 rpm water-cooled spindle. The optional ATC package includes a 1.8 kW, 60,000 rpm spindle.
EtherCAT Absolute Servo
SynMatic servo motors with 23-bit optical encoders, PMI C6 ball screws and Hiwin linear guideways support coordinated axis motion.
Enclosed Machining Workspace
Sheet-metal casing, dust protection and a cutting-fluid circulation system help contain chips and coolant during machining.
Desktop NC Ultra 2 Dry Run
Watch a dry run without stock material to see the coordinated machine motion. View the sample-machining section below for a cutting example.
Machining Capacity
From precision aluminum components to complex multi-sided parts, the Ultra 2 supports a range of desktop machining tasks. Actual cutting conditions and achievable results depend on the material, tool, fixture and CAM strategy.
Enclosed Five-Axis Machining
Integrated workspace with rotary workholding and cutting-fluid circulation for practical machining and prototyping.
Machining Range
- 5-Axis – Cylindrical: Φ150 × H105 mm or Φ100 × H120 mm
- 5-Axis – Cubic: W125 × D125 × H110 mm
- 3-Axis: X150 × Y190 × Z125 mm
- XYZ Effective Travel: X160 × Y200 × Z130 mm
- Maximum Machining Speed: 4,000 mm/min; varies by material
The usable envelope depends on the installed fixture, workholding method, tool length and rotary-axis position.
