Looking for a rotary brush machine?
Before you decide, discover Crossbelt technology.
The engineering behind the machine influences productivity, maintenance, running costs, part stability and the range of applications it can process.
Crossbelt technology offers a different engineering approach to deburring and edge rounding. The right configuration depends on the parts being processed and the required result. Discuss your application with NS Máquinas and SparX to assess the available options.

Rotary brush systems are well known in the UK market, but they are not the only solution for deburring and edge rounding. Crossbelt technology offers a different approach, with strong part stability, simpler machine design and greater flexibility for smaller components. For many manufacturers, it can be a more practical and cost-effective solution, depending on the parts being processed.
Crossbelt technology can be suitable for small parts. Suitability depends on the part geometry, material, thickness and machine configuration. Share representative parts with NS Máquinas and SparX so the application can be assessed and tested.
Not necessarily. Vacuum tables are often used in rotary brush systems to help keep small parts in position. The Crossbelt system is designed differently, using mechanical stability, pressure rollers and conveyor grip to control the part during processing. This can reduce machine complexity, energy consumption and maintenance requirements.
No. The DM Series is designed for a wider range of metal finishing operations. Depending on the machine configuration, NS Máquinas solutions can support deslagging, deburring, edge rounding, oxide removal and surface finishing, and can process laser-cut, punched and sheet metal parts. Edge rounding is often the main requirement, but the solution should always be selected according to the customer’s full production process.
The right machine depends on your parts, materials, thickness, burr type, required edge radius, surface finish and production volume. That is why NS Máquinas and SparX do not approach this as a catalogue sale. The process starts with understanding the application and identifying the right configuration for the customer’s production.
Yes, this is strongly recommended. Sample testing helps confirm the expected result before investment. It also allows the customer to compare finish quality, edge rounding, part stability and process efficiency with real production parts rather than theoretical assumptions.
SparX provides local support in the UK, working together with NS Máquinas. This includes application advice, installation, commissioning, operator training, technical support and spare parts assistance. The customer benefits from NS Máquinas engineering and local SparX expertise throughout the machine’s lifetime.
NS Máquinas brings European engineering, machine manufacturing experience and specialist knowledge in deburring, edge rounding and finishing technologies. SparX brings local UK market knowledge, application support, technical presence and customer proximity. Together, they offer more than a machine: they provide a complete solution with local support.
Crossbelt technology is mechanically simpler than systems that rely on rotary brushes and vacuum tables. The abrasive belts wear across the full working width, reducing the need to monitor different abrasive zones or compensate for uneven wear. Operators still need to manage normal consumable replacement and machine setup, but the process is generally simpler and more predictable.
The best next step is to discuss your application with the UK team. You do not need to know the exact machine or technology in advance. Share your parts, materials, current challenges and required finish. NS Máquinas and SparX can then recommend the most suitable deburring, edge rounding or finishing solution.
