Automatic solution for conic poles finishing

Traditionally, light pole producers have either manual polishing systems or centreless belt finishing machines. The first option is time consuming and requires significant labour costs. On the other hand, the available centreless machines, where the tube is rotated, show important safety concerns, as some tubes can be 12m long or more. With the MLW200 TC the abrasive belts rotate around the tube giving flexible finishing without spinning the tube. This enables the safe working of both short and long tubes. Additionally, drilled tubes or slightly out-of-round tubes can be processed through this

MLW200 TC version, is a round tubes finishing machine developed by NS Máquinas capable of automatically polishing cylindrical and conical tubes from Ø25mm to Ø205mm. The machine was designed to finish conic tubes without any manual adjustment, making it possible to polish a complete pole starting with Ø165mm and ending up to Ø75mm. The machine also permits the user to finish standard cylindrical tubes. The light poles industry was the original market targeted with this model, but any application that needs a consistent surface treatment on conic shapes can benefit from the technology.

machine. The feeding units feature a precise diameter compensation system which, combined with the solid structure, assures a vibration-free and safe tube transport operation. With a water cooling spray on the finishing area, MLW200 TC can polish different metals and safely work potentially explosive materials including aluminium. An automatic filtration and pumping system is integrated in the machine frame and can be easily removed for cleaning. MLW200 TC offers a fast and reliable process up to four metres per minute. It also assures a constant finishing even along the longest lengths. Changing abrasive belts is done in less than one minute. This brings a very fast and flexible process for productions with different poles specifications. MLW200 TC is equipped with a tube detection program, which automatically stops the abrasive belts motor every time there is not a tube on the finishing station. This automatic motor start and stop system reduces not only the consumption of energy, but also the bearings, rollers, v-belts and other mechanical components.
