Take Control with Ease

NDS-M80CONTROL-OPERATION-ICON-6 Intuitive Operation, Minimal Training

Operator efficiency is a direct contributor to shop profitability. The M8V Series is designed to minimize the learning curve and keep experienced operators productive from day one.

  
NDS-M80CONTROL-TOUCHSCREEN-ICON-7 Multi-Touch Touchscreen (Standard)

The M8V uses the same multi-touch gestures operators already know from smartphones and tablets. Pinch to zoom on program displays, drag and flick to navigate menus, and tap to select. No additional hardware or special training required.

  
NDS-M80CONTROL-COMPATIBILITY-ICON-8 G-Code Compatibility

The M8V runs industry-standard G-code and EIA programming. Operators familiar with other major control platforms can transition without learning a new language. Macro programming is also standard on every M8V control.

  
NDS-M80CONTROL-GUIDANCE-ICON-9 G-Code Guidance

Not sure about a specific G-code? Type the code in the edit screen and the control displays a diagram showing the format, required variables, and whether the command is modal. Built-in reference eliminates the need to pull up manuals during programming.

  
NDS-M80CONTROL-CONVERSATIONAL-ICON-10 Navi Mill Conversational Programming

For operators who prefer conversational programming over manual G-code entry, Navi Mill provides icon-based cycle creation for facing, contouring, pocketing, drilling, tapping, boring, and more. Easy-to-follow diagrams guide each cycle, and one-time setup for tools and materials makes switching between jobs straightforward.

  

Tool Management & Production Control

  • Smarter Tool and Production Management

    Managing tools across long production runs or high-mix environments requires visibility. The M8V centralizes tool data and gives operators real-time control over cutting conditions.

  • Tool Management System

    Create custom data for each tool, including tool shape, offset values, tool life data, and specifications, all displayed in one place. During each tool change, a tool icon appears on the monitor confirming the correct tool data is assigned to the active tool. This data carries over into Navi Mill conversational programming.

  • Cutting Load Control

    The control automatically adjusts feed rate so the actual load matches your predefined target during machining. Eight parameter groups let you dial in the right response for different tool and workpiece combinations, protecting tools and maintaining finish quality without constant manual override.

  • Machining Conditions Selection

    Configure up to nine machining condition sets and switch between them on the fly with a single G-code. Set aggressive parameters for roughing, moderate for semi-finish, and precise for final passes, then call each within the same program. This is especially valuable on Nomura DS Swiss machines running complex multi-operation parts.

Surface Finish & Accuracy

Precision Where It Counts

Surface finish and dimensional accuracy drive part quality. The M8V includes multiple features designed to maintain both, particularly on the complex geometries common in Swiss-type turning and high-speed milling.
SSS Control (Super Smooth Surface)

CAM-generated programs often produce tool paths made of small straight-line segments. SSS blends these segments into smooth curves, improving surface finish while reducing cycle time by 10% to 20% through fewer unnecessary accelerations and decelerations. Standard on all M8V controls.
OMR-CC (Optimum Machine Response, Contour Control)

OMR-CC adjusts control processing to match workpiece geometry, correcting for the gap between programmed and actual tool position. The result is approximately 11% faster machining compared to the previous M800/M80 Series with no loss in accuracy.
Tolerance Control

Activated within a program or by parameter, tolerance control lets you set the allowable deviation. Use a larger value during roughing to reduce cycle time, then tighten it for finish passes. Standard on all M8V controls.
Parameter Adjustment for High-Accuracy Control

The M8V provides a dedicated screen for tuning high-accuracy parameters using three intuitive machining indexes: cycle time, accuracy, and quality. Operators can optimize results without deep parameter expertise.
