HD-340 Horizontal 7-Head Stone Edge Polishing Machine
The HD-340 is a high-performance 7-head horizontal profiling and polishing machine designed for precision edge processing of marble, engineered stone, granite, and other stone slabs. Featuring a two-stage system—profiling and polishing—the machine uses 3 electroplated or sintered diamond wheels for contour shaping and 4 resin and sponge polishing wheels for a smooth, high-gloss finish. The profiling wheels gradually shape slab edges based on the wheel form, while the PLC-controlled polishing system automatically adjusts pressure and movement to ensure consistent results. Capable of producing various decorative edge profiles like full bullnose, ogee, pencil edge, and more, the HD-340 is also ideal for processing handrail edges. With fast processing speeds, stable performance, and excellent edge quality, this machine is a trusted choice for high-volume stone fabrication shops seeking reliable, repeatable results.
