Machine that makes “V” cuts
technical data

on marble granite and engineered stone slabs by means of diamond discs

Fixed bench machine designed and manufactured according to the up-to date concepts and fitted for making 45° degrees cut to realise V-grooves. The high speed of the holding spindle carriage and its special automatic devices allow it to achieve very high production levels.

01. features

The exclusive features of a Comandulli machine: Volcano

  • Main protection covers in stainless steel.
  • Strong electrowelded machine main structure fully worked by a milling machine
  • To prevent the machinery from rust, its structure and main parts are metallized through a modern treatment that follows different phases: sandblasting, metallization with zinc wire, priming coat with zinc phosphate epoxy product and final painting with a high solid polyacrylic enamel. Covers submitted to cataphoresis treatment which follows different phases: degreasing of the piece, spry or dipping pre-treatment, electroplating bath which uses the electric power to plate the paint as to make a uniform skin, after-washing and furnace baking.
  • Monolithic machine (made in one piece – excluding the rollers) that does not need foundations but can lay on the floor.
  • Carter in acciaio inox.


  • Machine with a fixed bench equipped with n. 2 spindles equipped with diamond wheels diam. 300 mm at 45° (one opposed to the other) to realise sloping cuts.
  • Spindles assembled on a travelling holding spindle carriage, with pinion/rack system operated by a grar motor; speed 0÷30 m/1’; Spindle sliding on screw ball guides placed on the lower part of the bench, properly protected against water.
  • Electrowelded loading bench equipped with n. 7 lines of omnidirectional rollers for loading and unloading the slabs.
  • Reference bar for the workpiece alignment.
  • Set of pneumatic holding slab pistons (no. 4).
  • Electric equipment, controlled by PLC; cutting controls both in automatic or manual.
    Roller table to support long pieces while working their heads.
  • Kit including keys, abrasive wheels etc..
