BASE
Monolithic high-thickness steel base electro-welded with rectified sliding surface.
REPLACEABLE WEAR-PROOF SURFACES
Made with special steel (UBNW.1.446), thickness 3 mm, to guarantee planarity over time and easy maintenance over time.
SURFACE TREATMENT
All parts are treated in our company, with sandblasting by hand, cold galvanising and coating with two component epoxy primer. On request, base and shoulders can be treated with Cataphoresis or hot dip galvanising. All screws are stainless steel.
4-BELT CONVEYOR
Driven by two large-diameter drums and inverter adjustable speed. Unique systems for cleaning and lubricating the belt. The drive drum is coated with vulcanised rubber to prevent slipping and ensure fl ow smoothly.
SPINDLE HOLDER BEAM
Sliding on the shoulders fitted with roller cage in oil bath, protected by sealed stainless steel telescopic guards. Hardened steel sliding elements replaceable and installed on the shoulders and on the bridge. The spindles are housed in the centre of the beam to ensure complete stability and eliminate any possibility of vibration.
BRIDGE TRANSLATION
With pinion and rack. Central gearmotor and antirotation bar with large diameter. Shifting speed controlled by inverter.
POLISHING UNITS
- Cast iron polishing spindles, installed in the centre of the beam, with thick and rectified chrome-plated steel shaft, sliding on bronze bushing, complete with pneumatic cylinder for lifting the polishing head. Each spindle is fitted with a pressure gauge to control pressure and counter-pressure to balance the head during the work.
- Motors. 11/15 kW motors with single or sequential start-up. Drive transmission through high-output pulleys and belts.
- CEMAR GOLD OSCILLATING HEAD, diameter 470 mm, complete with 6 small arms for "Fikert" abrasive tools.
- Automatic centralised lubrication system of the spindles with the possibility of setting quantities and intervention.
- Abrasive finished. The machine is equipped with a system to set the thickness of the piece being processed based on which a sensor installed on each head calls the attention of the operator to replace the abrasive when finished.
- Slab-guide supports with screw movement through flywheel from a unique station, complete with stainless steel slab-guide.
- Material presence detection unit to control the automatic up/down movement of the heads in case of discontinuity between pieces.
CALIBRATING UNITS
- They are positioned transversely to the belt, adjustable from 0-45 ° by servomotor and predisposed for the application of diamond rolls (up to 250 mm diameter).
- The up and down displacement takes place through a geared motor from kW 0.45 with automatic positioning to the work quota set by the touch screen.
- Rectilinear potentiometer for detection and control of the vertical displacement of the diamond roller spindle.
- Each machine is equipped with No. 2 vertical calibrating spindles of kW. 4,5 each, to remove the two residual bands left by the rollers at the extremity of the strips or tiles.
ELECTRONICS: THE "THINKING HEART" OF LEVICOMPACT
- Reliable. After careful testing, the parts are chosen from the leading companies in the specific sectors. To minimise the probability of failure or interference, a modern “can open” network system is installed on board, which drastically reduces the number of cables between sections.
- Software developed entirely by GMM, guaranteed over time, customizable according to customer requirements.
- 12" Touch Screen. Interactive graphics for complete machine cycle management with start-up in sequence of spindles, conveyor motor and bridge motor. To manage spindle down/up based on piece presence. To view the abrasive consumption status for each head.
- Data base. Broad possibility to store large amounts of informations about work done or in process.
