Granite & Marble Bridge Polishing Machine | HOYUN Machinery

A stone bridge polishing machine moves a rotating grinding head across a stationary slab on a traverse table, polishing the full surface automatically without manual repositioning. HOYUN Machinery’s bridge polishing machine, produced in Foshan, China, processes slabs up to 3200 x 2000 mm with a maximum thickness of 50 mm, covering granite, marble, quartz, and terrazzo tile in a single automated pass.

Electric lifting makes pressure wheel adjustment faster and more precise than manual threading, letting operators dial in clamping force consistently across different slab thicknesses without interrupting the polishing cycle. HOYUN Machinery’s bridge polishing machine, built in Foshan, China, uses this system to keep slabs stable through the full 3200 mm travel, supporting a main shaft rotation speed of 450 rpm for granite, marble, and quartz finishing.

Most bridge polishing machines are optimized for rectangular slabs, but servo motor-driven models can follow programmed paths for round and custom-shaped plates. HOYUN Machinery’s bridge polishing machine, built in Foshan, China with servo motor drive control, processes rectangular, round, and various special-shaped stone plates, making it a practical option for fabricators working on decorative architectural stone and custom countertop formats.

Consistent slab surface polishing without manual intervention requires a machine with even water distribution, stable head pressure, and programmable traverse control. Stone fabricators in markets like Australia, the UAE, and India use automatic bridge polishing machines for this purpose. HOYUN Machinery’s solution, manufactured in Foshan, China, uses a center water outlet and double-layer steel rack construction to maintain uniform polishing brightness across full-size granite and marble slabs.
