Our products

Product category: Polishing machines for tubes


Max Ø 114mm
Straight and curved tubes
1 station

Straight and curved round tubes finishing up to Ø114mm with maximum flexibility and consistency.

Tube polishing machine – ML100 – is the perfect choice for finishing the surface of round, oval and elliptical tubes.

The ML planetary system enables the work without rotating the tube, delivering the best results on both bent and curved tubes.

The auto feeding system transports straight tubes safely and automatically through the finishing station, enabling a consistent and high productive tube polishing quality.

ML100 Z

Max Ø 114mm

Straight tubes

2 or 3 stations

Quality and productivity: straight tubes multiple stations finishing up to Ø114mm.


Tube Finishing and Polishing Machine – ML100 Z – is a multi stations finishing machine for straight round tubes.

This round tube polishing machine is equipped with ML planetary system and enables a faster finishing work than single stations machines.

Automatic work set-up and control of all the information about the tube finishing is done in a mobile panel with integrated touchscreen. Tube finishing stations are completely independent. Final finishing of the round tubes is possible in one pass only.

DM1100 C

Edge rounding
up to 1100mm

Ideal for edge rounding of light burrs up to 1100mm working width.


Metal deburring and edge rounding machine – DM1100 C – performs edge rounding and removes sharp edges on both external and internal contours of stainless steel, steel or aluminium parts either cut in laser, shear or punching machine.

This machine works metal parts of different dimensions including products as small as 50x50mm.

DM1100 C – Metal Deburring Machine has a station with double cross belts for the metal deburring and edge rounding, leaving clean, soft and burr-free edges on the complete parts.

OD120 Tube End Deburring Machine

Burrs are projections of material beyond the workpiece limits. It consists of an undesirable extended surface over the piece. The burr formation is almost impossible to avoid due to manufacturing processes, formation mechanisms, shape and material properties. On the other hand, there are several deburring processes to remove efficiently the burrs from a different variety of geometries.

The usual and oldest process consists in manually remove the burrs by using an abrasive or wire brush deburring tool. This method is widely used because of its extreme flexibility, low cost and lack of technology needed. On the other hand, this process is time consuming which reduces the productivity in the production lines. Also, there are some disadvantages of the manual process: brush wires may be unleashed; the operator can lose control of the tube and, since the operator is more exposed to the brush and the cutting edges of the tube, may suffer hands injuries.
OD Tube End Deburring Machine is one the most efficient solution to remove tube and profiles end burrs, clean and remove tube sharp edges caused by sawing. This tube end deburring machine enables simultaneous outside and inside tube burrs removal without rotating the tube. The solution to deburr tube ends with OD Tube End Deburring Machine is the answer to the manual process with a productive, safer, simpler and flexible deburring method.

The operation is very simple because the operator doesn’t need to rotate the tube as the brushes rotate all around its shape. Also, due to its fast tube clamping system the OD Tube End Deburring Machine is capable to deburr and easily operate different shapes – from round to square tubes and aluminum profiles – treating all edges uniformly. This system was developed not only to fix the tube while doing the tube deburring process but also to cover the brush and avoid injuries for the operator as well as ensure a cleaner environment.

Automatic Tube Bundle Finishing Machine

MLW100 3Z tube wet finishing machine can be now equipped with automatic loading and unloading systems for complete tube bundles.
The tubes are delivered together in one single batch and are polished through the 3 planetary stations. The finished tubes are placed on the outfeed table without any operator intervention.
Saving handling time and operator intervention are the main benefits of these new automatic feeding systems.
Benefits of this machine and system:
  • MLW100 3Z: Three planetary stations wet polishing machine
  • Heavy bundle loading system designed up to 5 tons of material
  • Automatic loading and unloading tables designed for complete tube bundles (average 150 tubes with 12m length)
  • Mobile touchscreen panel and, by request, programs saving feature
  • Optimized productivity with automatic tubes handling counting with feeding speed up to 5m/min
  • Automatic water cooling and filtration unit up to 100l/min
