Levicompact 620-800

Excellence that is unrivaled.
Total and accessible quality has always been the top of the list of the GMM “mission”. The same commitment applied to the development of the more advanced version of the Levicompact series, automatic granite strips polishing machines. Following the construction philosophy that has always characterized the excellent Cemar product, the new series of polishing machines was developed using sturdy, precise and reliable mechanics. At the same time, technological and electronic solutions were developed to ensure maximum quality of the processed material, high production yield and reduced processing waste. Result: high level performance, low running and maintenance costs with high durability. All at an affordable cost for the Customer.

A customized solution for any requirement. To provide a solution for the specifi c needs of our Customers, the machines in the Levicompact series are produced in different combinations of calibrators and polishing units. All Everest machines can work individually or positioned in production lines, even complex. This last application is easy to implement, thanks to the accompanying Software, developed entirely by GMM.
Monolithic high-thickness steel base electro-welded with rectified sliding surface.
Made with special steel (UBNW.1.446), thickness 3 mm, to guarantee planarity over time and easy maintenance over time.
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.
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.
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.
With pinion and rack. Central gearmotor and antirotation bar with large diameter. Shifting speed controlled by inverter.
- 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.
- 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.
- 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.
The Levicompact series of GMM granite calibrating and polishing machines is available in different configurations, in order to satisfy the needs of each individual customer.
Standard width 620 - 800 mm.
All the machines have been designed with specific bases of various sizes, to house different combination of calibrators and polishing units. It is possible to have max 4 calibrating units and from 6 to 14 polishing heads.
Each machine model can be realized to be integrated into simple or complex lines, with a sense of travel with entry from the left or from the right, on customer request.
