Vertical Stone Edge Polishing Machine

This vertical edge polishing machine for stone is a high-performance processing solution designed for precision and efficiency. It excels at handling a wide range of single-layer and thick stone slabs, providing high-speed edge shaping, straight-edge polishing, chamfering, and contour finishing.

Compared to traditional models, this machine revolutionizes operation by enabling quick wheel changes and removal without complex adjustments, significantly reducing downtime. The grinding process uses a fixed-wheel method, while polishing is automatically controlled via a PLC-driven stepper motor, which regulates feed rate and provides automatic compensation.

This setup delivers unmatched convenience, efficiency, and cost savings for stone processing businesses, while ensuring products with exceptional surface quality, aesthetic appeal, and superior hand feel—meeting and exceeding customer requirements.

Vertical Stone Edge Polishing Machine – Full-Service Multi-Edge Processing

This vertical stone edge polishing machine is designed for precision finishing of a wide range of stone edges, including single-layer and thick materials. It can handle French edges, Roman edges, L-grooves, straight edges, beveled edges, ogee backs, water drips, and all types of custom profiles. It is ideal for processing marble, granite, quartz, engineered stone, and other types of stone surfaces.

Key Machine Features:

• Equipped with a snail joint coupling system.

• Motor Configuration:

  • Motor #1: 5.5 kW, rear-cut, installed at a 45° angle with a 12-inch (300mm) blade for back-cutting stone.

  • Motors #2-3: 5.5 kW, horizontal orientation, combined with four oscillating motors for custom profile edge processing.

  • Motors #4-5: 4 kW, vertical orientation, for bottom flat polishing and movable front-side edge work.

  • Motors #6-9: 3 kW, vertical orientation, for bottom flat polishing, side chamfering, and corner line finishing.

  • Chamfer Motors #10-13: 3 kW, with electric adjustable angles from 45° to 90° for chamfering, large bevels (using water grinding discs), and custom profile edges (using rubber wheels).

• Operational Flexibility: Can be operated manually, automatically, or in separate modules.

• Grinding Wheels: Compatible with up to 7-inch (18 cm) wheels.

• Synchronized Feed & Lift Rails: Adjustable based on stone size and thickness.

Capabilities:

• Handles a wide variety of flat stone surfaces, producing large and small rounded edges, French edges, straight bottom edges, 45° chamfers, top-and-bottom chamfers with side polishing.

• Side rounding (R-edge) and anti-slip stair edges with polished lines can be completed in a single pass.

• Slotting and polishing (e.g., “chicken beak” edges), ogee edges, and back-cutting using a 12-inch saw blade with automatic slurry separation.

• Coarse grinding, fine grinding, and polishing can be completed in one workflow.

• Finished stone surface brightness exceeds original board finish.

• Grinding wheel wear compensation can be adjusted manually while the machine is running.

Performance & Efficiency:

• Advanced, rational machine structure ensures high precision, fast processing speed, and easy operation.

• Adjustable feed speed and material depth control.

• Maximum processing speed: 16 ft/min (5 m/min).

• Equivalent output of 15 workers, eliminating human error and common fabrication defects.

This machine is a complete solution for high-efficiency, high-precision stone edge finishing and custom profile fabrication, ideal for marble, granite, quartz, and engineered stone production.
