Everest 2100

GRANITE SLABS POLISHING MACHINE
After several years of experience in the polishing fi eld, GMM present the evolution of Everest 2100 automatic polishing machine for granite slabs. In compliance with the construction philosophy which has always distinguished GMM products, the new range of polishing machines for granite slabs is realized with solid sandblasted structures and casings of high quality and resistance. Everest 2100, due to its compactness, applied technology, speed and reliability is an effective solution also for what quality, production and investment is concerned.

Quality is CEMAR’s first consideration in designing machinery. Features such as belt internal lubrication and cleaning are exclusive to CEMAR. The painting process is absolutely the most advanced in this fi eld. It guarantees extended life of all painted surfaces. Hermetic seals protect the beam assembly against water and dust, prolonging life and reliability. Pneumatic, electrical and electronic components are carefully selected from the industry’s leading suppliers.
Features
- Sturdy electro-welded steel structure base with ground belt sliding surface. 3 mm thick, replaceable STAINLESS steel sheets providing protection against wear and tear. Grease lubrication system to facilitate sliding of the conveyor belt.
- Steel electro-welded spindle-holding beam. Sliding on shoulders equipped with roller cages in oil bath protected by special stainless steel covers. Hardened steel sliding elements both on the shoulders and the beam. Variable speed translation by means of connecting rod and crank regulated by inverter.
POLISHING UNIT
- Spindles made of cast iron with forged steel, chrome-plated and ground shaft sliding on bronze bushes complete with 2 pneumatic lifting cylinders. Each spindle is fitted with a pressure gauge to check the pressure and counter-pressure balancing the heads during the
removal stage.
- 15 kW/20 HP motors with individual or in-sequence start-up. Drive is transmitted by means of pulleys and V-belts.
- 11kW/15 HP motors with individual or in-sequence start-up. Drive is transmitted by means of pulleys and V-belts.
- GOLD series PLANETARY heads Ø 450 mm with 5 GRINDING WHEELS.
- GOLD series TANGENTIAL heads Ø 470 mm with 6 ABRASIVES.
- Cleaning spindle made of cast iron complete with pulleys, belts and 0.75 kW motor coupled to a reduction unit. The upstroke/downstroke is performed by pneumatic cylinder. The spindle is mounted at the end of
the beam, outside of the shoulder.
- Optical detector for scanning the shape of the slabs in sequence and sending the data by serial line to the numerical control.
- Ultrasound sensor positioned at the entrance of the machine that detects the thickness of the material.
- Touch-screen control panel with interactive graphics for a complete control of the machine cycle with automatic starting up in sequence of the belt and beam motor spindles, regulation of spindle upstrokes/downstrokes according to the shape of the slab, control of wear and
tear on abrasives.
