  • CE certified machines.
  • Long experience in the manufacturing of these machines.
  • High standard of mechanical construction.
  • Use of first quality materials and special alloys.
  • Thermal treatment and special finishing of all parts subject to wear.
  • High precision gears, overdimensioned and adjustable, practically of unlimited life.
  • Easy and safe hydraulic plant, achieved to avoid overheating.
  • High precision of copying and grading and possibility to fit the same model on several machines getting the same results.
  • High grading capacity capable to obtain till 6-7 sizes over the model size. Not qualified manpower may run the machines, thanks to the easy working.
  • Thanks to the easy working, not qualified manpower may run the machines.
  • Possibility to process wood, plastic and aluminium lasts.
  • Maximum precision in last copying, without any influence of the material hardness.
  • During the copying operation, thanks to proper cams, it is possible to adjust the last rotation speed at shaped points, such as heel, instep and toe.
  • Hydraulic adjusted and controlled last rotation speed (0-100 rpm) (see picture 1). A mechanical gear adjusts the feed of the milling tools for each last revolution, allowing 6 different pitches or other different pitches on request (see picture 2).
  • We can easily adjust each tool-holder heads separetely (see picture 3) or we can regulate all the heads together by a different graduated lever (see picture 5).
  • The finishing operation starts from the heel and reaches the toe.
  • Adjustable pressure.
  • Automatic working cycle.
  • A lever (see picture 4) drives all operations.
  • According to the machine choice, you can work by one finish pass only or two passes, i.e. one pre-finish pass followed by one finish pass.
  • Strong hydraulic cast iron cylinders drive the tailstocks and allow the rotation of the shoetree at its best rigidity conditions.
  • All moving parts are oil bath or lubricated by a central unit for an automatic programmed lubrication.
  • Bed and sliding rams are made by Ni-Cr cast iron and thermally treated, and parts of the copying device are made by Mg alloys.
  • We can grade both length and step independently and with high precision.
  • An electronic device can be assembled on the machine to develop and adjust length and step automatically.
  • We can move 10 mm. the model along the shoetree (see picture 6) to adjust the length.
  • The movement transmission of the cutter-heads is simply made by two belts only for four heads. A strong and adjustable tightener allows fast replacement of the belts and an easy adjustment of their tension (see picture 7).
