Mirror Polishing Machines for Metal Tubes and Bars

Grinding and preliminary finishing may remove marks before the final polishing stage. Dedicated belts and polishing compounds are used where the configuration provides them. Preparation and final polishing have different functions; a mirror result should not be assumed from a standard satin-finishing machine.

Suitable orbital arrangements work around round or oval tube sections. Compatibility with bent tubes or other sections depends on the machine specifications and available workpiece clearance. The permissible diameter and bend geometry must be checked for the intended component.

Available configurations include working ranges of 5–50 mm and 20–219 mm in tube diameter. These describe separate machines, not the limits of every model. Selected powered-feed arrangements for straight tubes provide adjustable feed of 1–20 m/min. The suitable operating rate depends on the material, incoming surface and required finish.

Controlled feed maintains the workpiece path through the polishing area. The preparation, tools and feed settings are chosen together to develop the specified appearance along the tube. Polishing equipment and paste dispensing depend on the configuration.

The applications include stainless steel, steel and brass, with aluminium covered by selected configurations. Tube diameter, section, length, curvature and required appearance determine suitability. Selected straight-workpiece configurations also polish metal bars, with the working range set by the machine and bar dimensions. Garboli Range mirror polishing machines describe the corresponding line; bent-tube applications provide the geometry-specific route.

Metal finishing machines cover the wider family of satin and polished surface results. Contact Garboli with the material, tube dimensions and finish specification to discuss the appropriate mirror-polishing arrangement.
