From High-End Stone to Artificial Stone Surface Treatment Integrated Polisher Solving the Problem of Uneven Polishing Quality in Cross-Material Processing

Ledrobit Machinery Co., Ltd.

consistently monitors the diverse needs of the global stone processing industry, dedicated to resolving quality deviations across materials with different physical properties through intelligent integrated equipment.

In today’s architectural decoration market, stone fabrication plants often need to simultaneously process high-end natural stone, artificial stone, cement products, and even wood or glass. However, the Mohs hardness, thermal sensitivity, and porosity of these materials vary significantly. For instance, natural granite is extremely hard and requires high pressure and long grinding cycles, while artificial stone contains resin components that are sensitive to heat; excessive rotation speeds can easily cause surface "burning" or discoloration. Traditional fixed-speed equipment struggles to balance these requirements, leading to severe quality fluctuations and significant raw material waste when switching product lines.

The core competitive advantage of the Ledrobit integrated polisher lies in its high "parameter flexibility." By deeply integrating the CNC system with high-precision frequency converters, the equipment can preset processing curves tailored to different material characteristics. Once the vision scanning system identifies the workpiece profile, the CNC system retrieves the corresponding process parameters, dynamically adjusting the downward pressure and rotational torque of the polishing head. For high-end natural stones, the system focuses on multi-stage fine grinding; for artificial stones, it precisely balances cutting force and heat dissipation efficiency through non-contact path planning and frequency-controlled deceleration, ensuring the surface gloss reaches an Ra-level mirror finish without thermal damage.

Reliability in cross-material processing depends on rigorous control of power output and structural rigidity. Below is the core technical specification table for the equipment:

At the technical execution level, the 7.5kw frequency-controlled main motor is key to achieving cross-material versatility. It allows for real-time speed adjustment based on material hardness, ensuring smooth and stable power output when handling expensive high-end stones. Meanwhile, the Dual Y-Axis drive system provides robust dynamic support for the 3.2-meter gantry, eliminating micro-vibrations caused by uneven material feedback. Additionally, the 6m³/h total water consumption design is not only for debris removal but also to provide sufficient cooling for heat-sensitive artificial stones, preventing resin melting and ensuring high operational reliability.

To fully leverage the integrated processing advantages, we recommend that operators use a constant pressure mode for cement products or imitation stone materials and ensure the cooling water flow remains at the standard 6m³/h to extend abrasive life. For high-end natural marble, take advantage of the Automatic Tool Changing (ATC) function to configure a complete 5-7 stage grinding sequence. By identifying any 2-D shape via the vision system, even mixed processing of irregular parts from different materials can achieve maximum hourly output and consistent polishing appearance through the CNC system's intelligent allocation.

From the texture of natural stone to the uniformity of artificial materials, the core of cross-material processing lies in the precise management of physical parameters. By combining variable frequency power systems with heavy-duty dual-axis structures, we offer global customers a highly efficient production method capable of handling a vast array of materials. Ledrobit Machinery Co., Ltd. will continue to use technological progress to help you maintain a leading quality edge in the complex and ever-changing material market.
