MARAN – Excellence in Stainless-Steel Furniture and Equipment
MARAN is a Portuguese manufacturer specializing in stainless-steel furniture and equipment for demanding sectors, including healthcare and research, professional kitchens and hospitality, food processing, and hygiene services. From hermetic pass-through chambers for cleanrooms to industrial kitchen tables, stainless-steel buffets and hospital furniture (cabinets, tables, sinks and more), MARAN has built a reputation for quality, precision and hygiene. Every product undergoes a rigorous in-house process—from laser cutting and bending to welding and assembly—where flawless surface finishing is critical.
Perfect surfaces, seamless joints and smooth edges set MARAN apart and are indispensable in hospitals, laboratories, professional kitchens and hotels, where hygiene, durability, safety and easy cleaning are non-negotiable.
Challenge – Boosting Productivity and Edge-Finishing Quality
Despite substantial investment in laser-cutting and CNC-bending technology, MARAN faced a common fine-sheet-metal challenge: deburring and edge rounding after cutting. Previously done manually or with less efficient machines, this step created a genuine production bottleneck. Each month the company processes 5–8 tonnes of stainless-steel sheet 0.6 mm to 2 mm thick—hundreds of sheets in total. Manual finishing consumed excessive time, tied up skilled operators and still left sharp burrs and inconsistent finishes, slowing production and compromising quality.
Safety and hygiene were serious concerns: sharp edges could injure operators and hinder product sterilisation. In hospital and professional-kitchen environments—where stainless steel is chosen for its corrosion resistance and “total cleanability”—burrs or acute corners trap dirt, negating the material’s advantages. Finishing quality was therefore not merely aesthetic; it was functional, sanitary and safety-critical for makers and end-users alike.

Solution – DM1100 ZC for Integrated Deburring and Edge Rounding
The answer was to integrate the NS Máquinas DM1100 ZC into the production flow immediately after laser cutting. The DM1100 ZC is a compact industrial sander designed to deburr and round the edges of metal parts up to 1,100 mm wide in a single pass. Laser-cut parts—whether panels for pass-through chambers, stainless countertop sections, industrial kitchen shelves or hospitality components—are automatically fed through an abrasive-belt and brush system (“ZC” module) that removes burrs and leaves uniformly rounded edges with a consistent, safe radius.
One operator can run the machine easily thanks to straightforward settings and variable speed controls that adapt to different thicknesses and materials (stainless steel, carbon steel or aluminium). The DM1100 ZC’s compact footprint also allowed installation on MARAN’s production line without significant additional floor space.
“We make our products from birth to end of life — and that means thinking about safety and detail right after the cutting stage.” says MARAN’s Managing Director, Mário Silva. “The DM1100 ZC closed a critical gap: the laser-cutting → finishing → bending sequence now flows continuously, with no delays or rework.”
Impact – Higher Throughput, Lower Effort, Consistent Finish
90 % reduction in finishing time per part, eliminating the former bottleneck between cutting and bending.
Just 1 operator now handles deburring and edge rounding; previously, several operators were needed continuously.
Continuous, linear flow from laser cutting straight through finishing and bending, with no interruptions.
Smooth uniform edges improve handling safety and reduce accident risk across hospital furniture, industrial kitchen tables and stainless buffets.
Extended tool life for press-brake tooling and other equipment, preventing premature wear from burrs or sharp edges.
Premium touch and visible quality in the finished product—essential for sinks, cabinets, pass-through chambers, prep tables and catering stations.
Every component exits the DM1100 ZC uniformly finished, burr-free and blunt-edged—a tangible benefit for both producer and end-user.
Quality and Hygiene Gains
Easy, thorough sanitisation in hospitals, labs and industrial kitchens—no corners for dirt to accumulate.
Compliance with sanitary standards (HACCP, ISO) in food and clinical areas, as rounded edges simplify cleaning and remove bacterial harborage points.
Operational-Safety Improvements
Fewer manual grinding operations mean lower workplace accident risk.
A cleaner, more controlled shop floor thanks to the DM1100 ZC’s integrated extraction system, reducing airborne dust and sparks.
In short, the machine has delivered faster, safer production with superior quality, reinforcing MARAN’s status as a benchmark in metal-surface finishing.
Complementary Equipment – An Integrated NS Máquinas Line (ML100 and Future FG220)
MARAN’s optimisation strategy goes beyond the DM1100 ZC, leveraging additional NS Máquinas solutions:
ML100 – Planetary tube-polishing machine (Ø up to 100 mm). Essential for finishing handrails, table legs and tubular frames on stainless furniture for labs, service trolleys, hospital carts and industrial kitchens.
Flat-Grinding Line (FG) – Successor models for flat-profile finishing (sheets, bars) in stainless steel, giving a decorative, smooth standard to counter tops, shelves and food-prep tables.
FG220 2ZK (planned) – Machine for finishing rectangular bars and tubes (up to 220 mm wide) with multiple stations (abrasive belts and brushes). Enables polishing and grinding of square profiles and large sheets on both faces, boosting capacity and versatility for larger items such as buffet lids, industrial kitchen benches or hospitality structures.
Together these solutions form a complete finishing line in which every part—laser-cut sheet, cylindrical tube, rectangular profile or prep table—receives the right treatment swiftly and precisely. This synergy supports MARAN’s philosophy of keeping every product “from birth to completion” in-house, retaining full quality control at every stage.
Conclusion – Optimised Finishing, Competitive Edge
MARAN’s experience with the DM1100 ZC and other finishing machines shows how the right technology can turn a production challenge into a success story. By automating deburring and edge rounding, MARAN eliminated bottlenecks, enhanced worker safety and upgraded the quality of its stainless-steel products.
