  • Spira - Profiled and Flat Edges

Machine to create and polish pencil round profiles, flat edges and flat edge plus bevels.

Very simple machine, as to its mechanical components and its electrical and electronic equipments; easy to use and service.

The exclusive features of a Comandulli machine Spira

  • Electronic system that controls the advancement, the rotation, the descent of the holding slab piston, only when the slab passes.

  • Conveyor belt width 600mm driven on a flat stainless steel plate.

  • Dynamic/smart speed function: machine equipped with special software that, during the automatic cycle, varies automatically the belt speed to reduce downtimes according to the kind of working and the tools to be utilised.

  • Work-piece locking by pneumatic pistons

  • Main protection covers in stainless steel.

  • To prevent rusting of machine, the structure and the main components are metallized using a modern treatment composed of several phases: sandblasting, metallizing with zinc wires, epoxy paint with zinc phosphate, and final paint coat with polyacrylic polish. The covers are in durable stainless steel. All other metal sheets on the machine have been treated by cataphoresis in sequence they have gone through a degreasing bath, a pre-treatment full immersion, an electroplated bath that uses power to lay paint creating a uniform and consistent film after the rinsing is complete, it is then all baked and sealed in an oven.

  • Water tank with lateral outlets.

  • Manual lubrication.

  • Monolithic machine (made in one piece – excluding the rollers) that does not need foundations but can lay on the floor.
