Axis Configuration and Motion Control

  • X-axis: Left-right oscillation with centralized automatic lubrication

  • Y-axis: Feed movement with direct-drive technology and centralized lubrication

  • A-axis: Workpiece rotation with extended continuous swivel range (Blade seat projection length: 36 mm)

  • C-axis: Workpiece table angle adjustment from -91° to +91° (depending on grinding wheel and other conditions)

  • V-axis: Online grinding wheel cleaning system

  • W-axis: Blade core positioning with manual fine adjustment

  • Robotic Workpiece Handling: 3-axis linear robotic arm for tray loading/unloading, including B1, B2, B3 axes for transport and lifting

Maximum simultaneous CNC control over 9 axes enables complex, multi-dimensional grinding strategies.


Core Features and Advantages

Fully Automated Grinding Process

The MK-400PLUS provides one-clamping peripheral and land grinding for indexable inserts, eliminating time-consuming multiple setups. The integration of a robotic loading/unloading system automates part handling for uninterrupted, high-volume production.

Superior Precision and Rigidity

Constructed on a robust, high-rigidity frame, the machine maintains micron-level accuracy and exceptional surface finish throughout extended grinding cycles. Mechanical stability minimizes vibration and thermal drift, ensuring consistent and repeatable results.

Intelligent Measurement and Quality Control

Equipped with a sophisticated measurement system, the MK-400PLUS performs:

  • Pre-process dimensional verification

  • Post-process inscribed circle inspection

  • Automated rejection of defective inserts and rework logic

  • Automatic compensation for subsequent inserts to maintain tight tolerances

  • Optional 3D measuring probe for enhanced geometric analysis

Grinding Wheel Dressing and Blade Positioning

The dressing system, powered by a 1.5 kW electric spindle, allows precise side and profile dressing of grinding wheels, ensuring sharp cutting edges and uniform finishes. Blade positioning can be manually fine-tuned for perfect centering and alignment.

User-Friendly Software and Integration

The machine supports Agathon’s ToolLab software for simple and advanced programming capabilities. Whether for novice users or expert programmers, the software provides:

  • Guided workflows and preset templates for quick setup

  • Full control over 5-axis CNC toolpaths

  • Compatibility with the Evo platform’s hardware and tooling

  • Easy transition from other grinding systems


Design and Safety

  • CE-compliant, fully enclosed work area for operator safety

  • Centralized automatic lubrication for reduced maintenance

  • Compact footprint optimized for modern production floors

  • Energy-efficient design reduces operational costs

  • Intuitive HMI interface facilitates smooth operation and diagnostics


Application Range

The MK-400PLUS excels in grinding a wide variety of inserts for:

  • Carbide and Cermet tools used in general machining

  • Ceramic and CBN tools for high-speed and precision applications

  • PCD tools for abrasive materials such as composites and non-ferrous metals

  • Complex geometries with multiple cutting edges, chipbreakers, and special contours

  • Large batch production as well as flexible small batch jobs


Ideal Customers

  • Indexable insert manufacturers aiming to automate and scale production

  • Toolmakers requiring superior grinding precision and process repeatability

  • High-mix manufacturers needing flexible 5-axis grinding solutions

  • Companies integrating robotic automation for lights-out manufacturing


Summary

The MK-400PLUS represents the pinnacle of insert grinding technology, delivering fully automated, multi-axis grinding solutions tailored for the highest precision and throughput requirements. Its powerful combination of mechanical rigidity, intelligent measurement, and software integration makes it a critical asset for any cutting tool production operation seeking to enhance quality and efficiency.
