The technology applied to these automatic vertical milling machines is engineered for slotting double wall rigid PVC profiles of up to 600 mm in width, directly on the extrusion line.
The machine is positioned between the haul-off and the guillotine and carries out the slotting process using a milling unit composed of independent modules mounted on a suitably dimensioned cooled bearing plate, which can house up to 44 milling tool holders.
The multiple milling head is mounted on columns and moves up and down to carry out the milling on the profiles. Carriage movement is controlled and driven by a brushless motor designed to synchronise the milling with the profile speed.
The machine is also equipped with an external suction unit to remove dust and milling swarf so that the profile is clean and ready for the next working process.
The choice of materials, such as the electro-welded box section steel, the painted frame, the anodised aluminium structures that support the moving parts, and the stainless steel used for parts in contact with the profile are all hallmark signs of a top-quality machine.
Applications
This type of machine finds its main application field in the extrusion industry of perforated double wall cable trays – For single wall ducts have a look at our punching machines!
The production of customised milling tools allows extremely precise and clean holes/slots. This machine is designed to be extremely versatile and manufactured according to different production needs. It can be used for different profiles formats and multiple drilling/milling patterns, for example, for double wall PVC cable trays.
