LMS 2100 Automatic Belt Polishing Machine for Marble Slabs

AUTOMATIC BELT POLISHING MACHINE FOR MARBLE SLABS
Thanks to CEMAR’s over twenty years experience in surface treatment of marble and granite, GMM present the most advanced version of LMS 2100 belt polishing machine for marble slabs. Respecting the philosophy that has always characterized the excellent CEMAR product, the new series of polishing machines for marble slabs is made using robust, accurate and reliable mechanics. In conjunction, the machine has advanced electronic and technology solutions to ensure maximum quality of work, high production yields and reduction of waste. All this ensure low running and maintenance costs, with high durability.
FEATURES
BASE
In sturdy electro-welded steel structure with rectified sliding plane covered with replaceable wear plates made of 3 mm thick special steel to ensure flatness and easy maintenance over time.
SURFACE TREATMENTS
All components are treated in our company with sandblasting by hand, cold galvanizing and painting with two component epoxy primer. On request, base and shoulders can be hot dip galvanized.
BELT
Pulled by two drums of large diameter. Speed adjustable by inverter. Two unique systems for cleaning and lubricating the belt to ensure flow smoothly.
BEAM
For spindle housing in a sturdy and rigid structure of welded steel. Sliding on the shoulders equipped with roller bearing in oil bath, protected by telescopic guards in stainless steel. Sliding elements made of hardened steel interchangeable and mounted both on the shoulders and on the bridge. The spindles are housed at the center of the beam to ensure complete stability and to avoid any possible vibration.
TRANSLATION OF THE BRIDGE
With rack and pinion. Starting from the version with 12 spindles, the transmission takes place with 2 gearmotors coupled at the bridge ends. Travel speed controlled by inverter.
POLISHERS SPINDLES
In cast iron, with thick chrome-plated steel grounded shaft, sliding on bronze bushes, complete with pneumatic cylinder for raising the abrasives carrying plates. Each spindle is equipped with a gauge for the control of pressure and counterpressure, necessary to balance the head during the working. The cooling water passes inside the shaft for a better and uniform distribution on the materials being processed.
MOTORS
11 kW/15 HP motors, with individual or in sequence start-up. Motion transmission with high performance belts.
ELECTRONICS: “THINKING HEART” OF THE LMS 2100
- Reliable. After careful controls, components are selected among leading companies in specific sectors (mainly Siemens or Schneider-Telemcanique).
- To make minimum the probability of failure or interference, on board of the machine is adopted modern network system "can open" which drastically reduces the number of cables between one section and the other.
- Software. Developed entirely in GMM, guaranteed over time, especially improved and customized according to customer requirements.
- Inverters. The roller conveyors and specific rollers in the entry are handled by inverters, like all the other moving parts, to balance the fl ow of material and optimize the speed of each step.
- Optical detector 120 photocells, to scan in a sequence the shape of entering slabs, done in RS485 protocol (noise free), it transmits the shape of the slab to the control unit to better manage the ascent and descent of the heads, according to the various selectable working cycles.
- Ultrasonic sensor, positioned at the entrance, to detect the material thickness. Enables fully automatic management of the abrasives consumption of each single head.
- Automatic lubrication management, for planning the quantity of lubricant to be dispensed and the dispensing times.
- Touch Screen 12". Monitor with "easy to use" interface, interactive graphics for the complete management of the machine cycle with sequential startup spindle motors, belt and bridge motors. It drives the spindles up-down stroke according to the shape of slabs. Display of abrasive consumption status for each head.
- Data base. Large possibility to store various information about the work done or in progress.
