Machine built up in steel on sole body frame, solid and strong carrying structure with special materials and adequate treatments able to sustain continuous movements, bending and vibrations. All operation is via a sturdy electrical panel, divided into the following working stages, starting from the first in sequence to the last working stage:

  1. Unblading by roll rotation with converter and rotative hammer pneumatic unblader
  2. Cylinder cleaning by manual vidia scraper and cylinder adequate speed. Obtained by inverter.
  3. Blades assembly by copper, with adequate dimensions, according to the blade thickness. The Blade lock is by a pushing wheel on copper while the copper is beaten by a pneumatic hammer, the whole process happens automatically with the cylinder variable rotation.
  4. Head blade cutting at the cylinder length
  5. Automatic and continuous rectification of the blades by sharpener control; variable speed roller by inverter, according to the hiding of different types of blades, going on and repeating till the rectification is completed.
  6. Check of the four cardinal points of the cylinder centering by a comparator.
  7. High speed cylinder rotation (from about 400 to 800 rev. ) by inverter, with high precision electronic balancing of the two cylinder sides.
  • The position of the pneumatic hammer is vertical, placed above the roller and in front of the operator; this hammer allows the ‘tool’ to work exactly for all its width of mm 250. Beating the copper without pulling it (without the stretching effect)
  • The hammer is totally automatic: means that it is positioned, can be lifted up or down automatically by pushing a button, it starts automatically to beat. In other re-blading machines the operator shall accompany the pneumatic hammer which is fixed on the re-blading machine by hand and always push the button for let it working; keeping in hand the hammer means to absorb all the vibrations.
  • Our machine is the only one which allows balancing each blade rollers at the same speed which the roller is running on the shaving or fleshing m/c or whatever. This thanks to a proper ‘inverter’ for changing the speed; the balancing happens at speed of 900 r.p.m. – max.
  • The coil of the copper has been placed laterally respect to the operator and follows by itself the movement of the turning roller.
  • NEWS: New electronic grinding wheel balancing system: installed in position with front view on the left side of the machine; it is possible to balance not only the grinding wheel but also the grinding wheel before its installation on the machine.

This machine, beside having been built for reblading of the cylinders for shaving and fleshing machines, can be used also for others balancing operations, depending on the length and diameters of the pieces introduced in to the machine.
