Mirror Finish Granite Polisher | Auto Flatness Detection

Achieve Mirror Perfection: ZDMJ-20C Automatic Granite Resin Polishing Production Line

In high-end stone processing, polishing is not just the final step-it is the decisive factor that determines the final product's market value. The Ruisheng ZDMJ Series Granite Polishing Machine is engineered specifically for those pursuing a "mirror-like" finish. By replacing traditional rigid grinding blocks with advanced Resin Abrasive Disc Technology​ and integrating intelligent control systems, we provide the ultimate solution to industry pain points such as uneven gloss and slab warping.

1. Resin Elastic Grinding Technology
We utilize high-quality resin-bonded diamond discs instead of conventional abrasive blocks. The resin material offers excellent elasticity, allowing it to perfectly conform to the microscopic凹凸 (irregularities) of the granite surface for "flexible polishing."

Result:​ Completely eliminates micro-scratches, significantly enhances gloss, and delivers a true crystal-clear mirror finish-ideal for premium exterior cladding and interior flooring.

2. Intelligent Plate Shape Error Detection Device
This is the "eye" of a high-end polishing machine. Equipped with high-precision displacement sensors, the system scans each slab in real-time.

Function:​ Automatically detects slab flatness and warping. Data is sent to the central PLC, which adjusts grinding pressure or triggers an alarm if anomalies are detected, ensuring flatness errors are controlled at the micron level.

3. Fully Automatic Lubrication System
Temperature rise in bearings and transmission parts is a major cause of equipment wear. Our automatic lubrication system delivers oil to critical components at timed intervals.

Value:​ Significantly extends machine lifespan, reduces manual maintenance, and ensures processing accuracy remains consistent during 24/7 operation.

4. Ergonomic HMI & Visual Control
Features a 10-inch HD touchscreen displaying grinding head speed (0-4m/min adjustable), belt speed, and power consumption. The intuitive interface allows operators to master the machine after minimal training.
