Comandulli Coral

The Comandulli Coral is an automatic edge polishing machine designed for processing straight edges on natural stone, quartz and ceramic materials.

Built around Comandulli's established edge-processing technology, the Coral combines automated operation with a robust construction to provide consistent, high-quality finishing across a range of materials and thicknesses.

Machine Features

The Coral is constructed around a fully machined, electro-welded steel structure.

The machine is protected against corrosion through a multi-stage treatment process incorporating sandblasting, metallisation and painting. Painted covers undergo cataphoresis treatment, while the main covers are manufactured from stainless steel.

Its specialised conveyor belt and pneumatic slab-locking system allow edges to be polished without the need for a contrast bar.

The 600 mm wide conveyor belt features variable speed control, with automatic speed adjustment available through the machine's control panel. The belt runs across stainless-steel support plates.

Each spindle operates independently, providing greater control throughout the polishing process.

A water collection tank with two lateral outlets is incorporated into the machine, while solenoid valves automatically control water flow to help reduce unnecessary water consumption.

Maintenance requirements are reduced through an integrated belt-cleaning system and automatic lubrication.

Automated Material Detection

Two sensors automatically detect the shape of material entering the machine, including irregular pieces such as winding steps and bonded components.

An additional sensor measures the thickness of each slab entering the machine, allowing the Coral to automatically adapt to variations in material thickness.

The polishing units operate across vertical and horizontal axes to accurately follow the material throughout the finishing process.

Designed for automated edge processing, the Comandulli Coral provides fabricators with a reliable solution for achieving consistent finishes while reducing the amount of manual processing required.
