Multi Edge Polisher

Omega Pencil

Designed according to the up-to-date concepts and structural principles, the automatic multi-spindle belt polishing machine model OMEGA PENCIL, is remarkable for its high productivity and its high-quality performances on every kind of marble, granite, engineered stones and ceramic.

BACA Omega Pencil
Overview

Maximizing countertop production, the Omega Pencil's cutting-edge design combines diamond abrasives and polishing pads on a conveyor belt, setting a new standard in efficiency for crafting rectangular countertop parts.

Its versatility and precision enable it to create a wide range of edge profiles, from simple bevels to intricate bullnose edges, catering to diverse customer preferences and design requirements. This capability not only enhances productivity but also offers a significant competitive advantage in the market, as it eliminates the need for multiple machines and provides a one-stop solution for edge polishing.

Omega Pencil is equipped with a calibrator that uses a diamond tool to mill the B-side of parts to the desired thickness. Milling the B-side of the stone, ensures that the countertops will sit flush on the cabinets minimizing the need for use of shims at installation.
