Features
This model is aCNC Slotting Machinedeveloped for motor rotor commutator slot cutting.
With CCD visual positioning system, it automatically scans and identifies the slot to ensure that the processing slot is not biased.
Full servo motor transmission control provides good positioning accuracy and high stability.
With industrial vacuum cleaner, when the cutting spindleis cutting, the industrial vacuum cleaner will suck the residue out of the machine tool to form chipless processing.
The rotary shaft adopts servo motor with high-precision harmonic reducer, which hashigh rotation positioning accuracy and can be processed at any angle of 360 degrees.

Overview
The DNC-550C High-Precision Motor Rotor Orienter CNC Slotting Machine by DUOMI CNC is an advanced 4-axis industrial machining solution engineered specifically for high-speed, automated slot cutting on motor rotors and commutators. Featuring an integrated CCD vision camera system, full-servo transmission, and high-precision harmonic rotaries, the DNC-550C delivers exceptional repetitive accuracy (±0.02mm) and operational throughput across diverse electrical manufacturing lines.
Designed to meet CE industrial safety compliance, this unit delivers automated, chipless machining using high-volume industrial vacuum technology to maximize production uptime and tool life.
Key Engineering Advantages & Features
- CCD Visual Positioning System: Automatic optical slot scanning and alignment eliminate off-center cuts, automatically generating cutting programs for up to 120 slot configurations.
- High-Precision 4-Axis Control: 4-axis (XYZA) servo-driven execution with harmonic reducers enables full 360° indexed indexing and precise multi-angle machining.
- ±0.02mm Repeat Positioning: Radial and axial runouts maintained within ±0.02mm ensure ultra-strict tolerance thresholds for automotive and industrial motor components.
- Integrated Chipless Processing: Heavy-duty industrial vacuum extraction (≥3.0kW power, ≥300m³/h air volume) instantly evacuates metallic swarf, maintaining a clean cutting zone and preventing rotor surface contamination.
- Robust Mechanical Stability: Precision brand guide screws paired with hand-scraped mating surfaces provide high dynamic rigidity across long production runs.
