Compared to manual polishing, our machine provides full automation that eliminates physical labor and operator fatigue while delivering better consistency.
Unlike mono-head automatic polishers that require multiple setups for different grinding stages, our multi-head system automatically transitions from coarse grinding to fine polishing in a single operation. This reduces processing time by up to 50% while eliminating handling damage between stages. The integrated visual recognition system further distinguishes our machine by enabling precise processing of irregular shapes and complex forms that mono-head machines cannot effectively handle.
How does the visual recognition system work for irregular stone shapes?
The visual recognition system in our CNC ATC Grinding & Polishing Machine uses a high-resolution digital camera mounted above the working area to capture images of stone materials regardless of their shape or size.
When a stone piece is placed on the machine bed, the camera takes photographs that are processed by our proprietary image recognition software. The system automatically identifies the contours of irregular shapes, creating a digital outline of the workpiece. Operators can then use the touchscreen interface to select specific areas for processing or choose the entire surface with a single click.
The software analyzes the shape characteristics and automatically generates optimal grinding paths that follow the contours of the material. This eliminates inefficient processing of areas beyond the stone edge and ensures complete coverage of complex shapes. The system adapts grinding pressure and tool position based on the specific geometry, maintaining consistent quality even on curved or angular surfaces where conventional machines would struggle.
