Marble feature walls and decorative panels represent luxury and refinement in high-end architectural applications, with their distinctive veining patterns and timeless elegance enhancing spaces from grand hotel lobbies to executive boardrooms.
The DINOSAW polishing system excels in revealing the inherent beauty of marble through its precision-calibrated finishing process. Our system's laser profiling technology automatically maps the marble slab's dimensions and adjusts the polishing parameters accordingly, ensuring consistent results even with marble's natural variations. The machine's PLC control system maintains exact speed and pressure calibrations throughout the finishing sequence, progressing from initial calibration to final polish while preserving the intricate veining characteristics that make each marble panel unique.
For fabricators specializing in architectural marble applications, our polishing system delivers the perfect balance of production efficiency and artisanal quality, reducing processing time while maintaining the flawless finish that luxury projects demand.
Granite > Countertops & Flooring

Granite countertops and commercial flooring remain the gold standard for durability and aesthetic appeal in high-traffic environments, with growing demand in global markets for their exceptional resilience and striking visual characteristics.
The DINOSAW Multi-Head Polishing Machine transforms raw granite slabs into perfectly finished surfaces with mirror-like polish. Our advanced diamond and resin-bond abrasive system with 8-24 polishing heads progresses through multiple grit sequences, starting with coarse diamonds to remove gang saw marks and continuing to ultra-fine resin-bond pads for that signature high-gloss finish. The independently pneumatic-driven polishing heads maintain precise pressure distribution across the entire surface, eliminating inconsistencies even on large-format slabs.
By implementing our polishing technology, fabrication shops achieve premium-grade finishes with significantly reduced labor costs, substantially increasing daily throughput with just two operators - a productivity level that traditional manual finishing methods simply cannot approach.

FAQs
Common Questions About Granite Polishing Machines
How to polish granite after cutting?
The professional polishing process for cut granite involves multiple stages, starting with coarse grinding to remove saw marks, followed by progressive finer abrasive sequences, and finishing with ultra-fine polishing to achieve a mirror finish. For industrial-scale production, a multi-head automatic polishing system is essential.
The most efficient approach uses multi-head polishing machines with 8-24 polishing heads working simultaneously through programmed sequences. This system replaces traditional manual polishing (where operators control a single grinding head) and single-head machines (requiring manual abrasive changes between stages). The PLC-controlled process ensures consistent pressure, speed, and abrasive progression across every slab, delivering uniform quality impossible with manual methods.
Water cooling is critical throughout the process to prevent heat damage and extend abrasive life. For optimal results, polishing should progress through 6-8 abrasive stages from 50-grit through 3000-grit. The automated system handles this progression seamlessly, allowing fabricators to process marble, granite and engineered stone with minimal labor while meeting tight project deadlines.
What materials can a stone polishing machine process?
DINOSAW polishing machines are versatile systems capable of processing a wide range of dimension stone and similar materials, including Granite, Marble, Engineered stone, Porcelain slabs, Tiles, Terrazzo and other Natural stones.
The Stone Polisher parameters (pressure, RPM, abrasive progression) can be calibrated through the PLC control system to optimize processing for each specific material type. Different abrasive sequences are recommended depending on the material's hardness and desired finish level.翻译:
How many operators does a stone polishing line require?
One of the key advantages of the DINOSAW stone polishing system is its minimal labor requirement. A complete polishing line typically requires only 2 operators:
• One operator manages the loading zone, ensuring proper slab placement and initial quality control
• One operator oversees the machine operation through the PLC interface and handles final inspection
The automated system handles the entire polishing sequence without operator intervention, allowing staff to manage multiple aspects of production simultaneously.
What's the typical production capacity of stone polishing equipment?
The DINOSAW stone polishing system delivers exceptional productivity with substantial daily throughput in standard 8-hour operation. Actual production capacity depends on several factors:
• Polishing head configuration (more heads generally increase throughput)
• Material type (harder materials typically require longer processing cycles)
• Finish requirements (higher gloss levels require additional processing stages)
• Slab dimensions and thickness
• Production line configuration (automated material handling increases efficiency)
Many fabrication shops operating with optimized configurations and extended shifts achieve significantly higher outputs. The system's reliability allows for continuous operation with minimal downtime, maximizing production capacity and return on investment.
