V-Axis: Online grinding wheel cleaning to maintain consistent wheel sharpness and performance.
This multi-axis arrangement facilitates complex 3D machining and chamfering in a single setup, eliminating secondary operations and ensuring excellent dimensional repeatability.
The grinding spindle is powered by a 7.5 kW 3-phase induction motor, providing stable and consistent torque for demanding grinding tasks. Complementing this, a 1.5 kW electric spindle powers the dressing device, which performs real-time grinding wheel shaping and conditioning to guarantee optimal surface finish and accuracy.
To achieve full automation, the MK-350 integrates a 3-axis robotic arm system that manages:
Loading and unloading of inserts.
Tray transportation and positioning.
Precise placement and retrieval of workpieces during the grinding cycle.
The robotic system handles multiple tray types:
Standard trays (350 mm × 350 mm), accommodating standard insert batches.
T-type trays (190 mm × 370 mm), suitable for specialized or smaller production runs.
This automated material handling minimizes downtime and maximizes productivity.
The MK-350 is equipped with an advanced online inspection system that measures critical dimensions before and after grinding, including:
Blank material verification to ensure correct insert size and shape.
Post-grinding dimensional accuracy checks for inscribed circles and chamfer quality.
Automated rejection of defective parts, along with regrinding commands or corrections for subsequent pieces.
This closed-loop quality control enhances production yield and guarantees compliance with strict quality standards.
The machine’s CNC system is designed for ease of use and flexibility:
Dialog-based programming interface simplifies the setup of insert geometries and machining parameters.
Support for a variety of standard insert profiles and the ability to program custom shapes.
Automatic path generation and optimized grinding sequences to reduce cycle time.
