  • Feed unit:
    The optional feed unit ensures convenient and efficient processing of the pipes. The feed speed can be continuously and individually adjusted via a potentiometer.
  • Sanding belt change:
    The sanding belts can be changed in seconds: A foot switch unlocks the sanding wheel and the user-friendly clamping device enables the sanding belts to be changed quickly and easily.

  • Diameter adjustment:
    The pipe grinding machines from NS Máquinas have a precise scale that makes it easy to adjust the grinding diameter. In addition, pipes do not have to be ground all the way through: The foot switch can be used to open the sanding belts so that specific areas can be worked on.

  • Perfect surface finish:
    In contrast to manual belt sanders, the machine ensures even processing of all areas. The result is a flawless and consistently uniform sanding pattern.

The technology of our pipe grinding machines

Grinding station ML/MLW

Antrieb Rohrschleifmaschine

With the specially developed planetary grinding technology from NS Máquinas, both straight and curved tubes can be processed effortlessly. Thanks to an innovative quick-clamping system, the workpiece diameter can be set. The workpiece is then simply fed into the machine by hand.

MP polishing station

Antrieb Rohrpoliermaschine

New at NS Máquinas is the innovative, self-developed planetary polishing technology, which – similar to the standard version – enables you to polish your workpieces effortlessly. Three polishing wheels rotate orbitally around the workpiece and ensure a uniform result. In addition, the machines in the MP series are equipped with an automatic system for the precise application of polishing soap.

Multi-sanding station ML/MLW Z

FAQ: Answers to the most important questions
What are pipe grinders needed for?

Tube grinding machines are used for processing, grinding and polishing tubes and cylindrical workpieces. They perform numerous tasks in various industries, including metalworking, furniture manufacturing and construction. The main applications include:

  1. Surface treatment:

    • Improvement of the surface quality, e.g. for decorative purposes.
    • Production of even, matt, brushed or polished surfaces.
  2. Deburring:

    • Removal of sharp edges, burrs or unevenness after cutting or welding.
  3. Preparation for coatings:

    • Creation of an optimum surface for painting, coating or powder coating.
  4. Tube forming and precision:

    • Achieving precise diameters or shapes through uniform material removal.
  5. Cleaning:

    • Removal of rust, oxidation layers or residues from pipes.
  6. Weld seam processing:

    • Smoothing of weld seams to level out transitions and improve strength and appearance.

Pipe grinding machines are particularly advantageous as they adapt to the cylindrical shape of the workpieces and can deliver efficient, uniform results on long or curved pipes. They are often used in stainless steel processing, railing construction and industrial plants.

The use of a pipe grinding machine is worthwhile if certain requirements and conditions are met during operation. Here are some important aspects that indicate that its use makes sense:

  1. Large quantities
    If large quantities of pipes need to be processed regularly, a pipe grinding machine is more efficient and time-saving than manual processes.

  2. Consistent surface quality
    If a uniform surface finish or a specific finish is required (e.g. for stainless steel pipes), the machine offers significantly more precise results.

  3. Complex geometries
    For pipes with different diameters, bends or hard-to-reach areas, a specialized pipe grinding machine can achieve better results than manual processing.

  4. Increasing productivity
    If production is to be increased without compromising quality, the machine can optimize processes by automating machining.

  5. Reduction in reworking
    A pipe grinding machine can ensure that less reworking is required, which reduces labor and material costs.

  6. Occupational safety and ergonomics
    If manual processing is stressful due to noise, dust generation or ergonomic reasons, a pipe grinding machine improves working conditions.

  7. Economic consideration
    The use is worthwhile if the costs of purchasing, operating and maintaining the machine are justified by the increased efficiency and quality.

Examples of typical areas of application:

  • Metal processing: stainless steel tubes for railings, furniture or mechanical engineering.
  • Metal construction: processing of pipes for construction projects, e.g. railings or supporting structures.
  • Automotive industry: surface treatment of pipes for exhaust systems or frame structures.
  • Medical technology: Dust-free stainless steel or nitinol tubes, e.g. for stents.

A pipe grinding machine is used to grind and polish pipes and round steel. It usually works with a system of abrasive belts that are guided by rollers. There are both stationary and hand-guided versions. In addition to grinding, a pipe grinding machine can also be used for satin finishing and polishing pipe constructions.

Some models, such as the ML100 from NS Máquinas, use a planetary sanding system. The sanding belts rotate around the pipe while it is being transported in a straight line, without the pipe itself rotating. This reduces the frictional heat on the surface of the pipe and enables even processing.

The operation of a sanding machine is generally based on the rotating or oscillating use of sanding tools that remove material from workpieces. This process is used to smooth surfaces, process edges or achieve certain shapes.

In summary, a pipe grinder works by using abrasive belts that rotate around the pipe and remove material to create a smooth and polished surface.

Our pipe grinding machines are suitable for a wide range of materials, including:

  • Stainless steel: Perfect for polished and satin surfaces.
  • Aluminum: For precise and gentle processing of soft materials.
  • Steel: Ideal for deburring and smoothing sharp edges.
  • Brass and copper: For a glossy finish and precise edge processing.
  • Plastics: Suitable for special applications with sensitive materials.

Thanks to the adaptability of our machines, they can be easily adjusted to the specific requirements of different materials to achieve optimum results.
