🔹 Product Description

The Pneumatic Tool Change Machining Center is a high-performance CNC machine designed for automatic and precise processing of stone materials such as marble, granite, quartz, sandstone, and ceramic tiles. Engineered with a robust pneumatic tool change system, it offers flexible and efficient switching between multiple tools, enhancing productivity and accuracy in complex operations.

Ideal for fabricating countertops, under-table basins, edge polishing, grooving, engraving, and more, this machine is especially suitable for stone processing factories that require continuous, automated, and high-precision production. It supports CAD design import and offers template-based processing for common shapes like circles, ellipses, and squares, ensuring easy setup and exceptional results.


🔹Key Features

  • Pneumatic tool change system allows fast and stable multi-tool operations without manual intervention.

  • High spindle speed (18,000 rpm) ensures smooth and detailed cutting, polishing, and engraving.

  • Compatible with CAD drawings, supporting quick import of customized patterns for efficient workflow.

  • 3-axis linear guide rails (X, Y, Z) provide high positioning accuracy and strong structural stability.

  • Touchscreen interface for user-friendly operation and programming.

  • Template-based processing simplifies standard shapes like circles, polygons, squares, etc.

  • Supports height measurement device (optional) for consistent depth cutting and polishing.

  • Low-maintenance and energy-efficient design, suitable for long working hours in industrial settings.
