RR630-Dry

The RR630 Deburring Machine is designed for deburring and surface finishing of metal sheets and parts up to 630mm working width. It is an ideal solution for parts processed by laser cutting, punching, or shearing.
Equipped with two wide abrasive belt stations, the machine is suitable for processing small parts from 50x50mm up to 630mm width. It also supports surface finishing, capable of using both standard abrasive belts and non-woven (Scotch) belts for flexible finishing options.
The RR630 is designed to be modular and can be integrated with an edge rounding machine via a connecting conveyor belt, allowing users to complete deburring and edge rounding in one pass.
The machine features two abrasive belt stations.
Each station is equipped with a large diameter contact roller (Ø60mm, 55SH hardness), allowing for effective deburring and high-quality surface finishing.
Specially developed to remove light burrs from parts cut by laser, punching, or shearing processes.
Allows surface finishing of metal sheets up to 630mm width and small parts from 50x50mm.
Supports standard abrasive belts and non-woven (Scotch) belts to meet different finishing requirements.
Ensures stable and efficient feeding of parts with a high-grip conveyor system.
Suitable for various shapes and sizes, including small parts (50x50mm).
Intuitive control panel allows operators to:
Turn on/off the conveyor and sanding belts.
Adjust speeds via frequency inverters (variable speed).
Monitor motor load with a digital ammeter.
Precisely adjust part thickness with a fine-tuning hand wheel (accuracy of 0.1mm).
Can be integrated with an edge rounding module, allowing deburring and edge rounding to be completed in a single pass.
Connecting conveyor system enables seamless integration between deburring and edge rounding stages.
