Tower

VERTICAL POLISHING MACHINE FOR STRAIGHT EDGES

The Tower range of line machines have been designed to work on all types of marble, granite, stone and agglomerate materials. All the Tower machines are characterized by compact size and extreme ease of use which is matched by excellent productivity. The micro-oscillation (“swing”) of the spindle-holder bar makes the Tower versatile, suited for both specific and specialized production and mass production. In addition, these machines are able to work on particularly narrow strips (50 mm) to produce the flat edge on baseboards or on the “back splash”. With different possibility of compositions this machine can meet the customer’s specific requirement.

Features

MACHINE BED
Strong electroweld, fully worked with numeric control machines. Sanding followed by a cold-galvanized treatment and two successive coats of dual component epoxy paint.

BELT
Three-layer, 30 cm wide belt has a grooved guide on the base to guarantee the maximum adherence of the belt to the line to be worked. Belt gliding surface is ground and covered with a special interchangeable wear-resistant steel plate.

SPINDLES
Standard: identical on all work units. Fitted with a bellows for slide protection and having a double labyrinth seal to protect from water, moisture and dust. To further guarantee the seal, there is a slight internal pressure.

SPINDLE-HOLDER BAR
Polishes the edges, using universal tools. The spindles, each one controlled by its own electric motor (protection IP65), are housed in a sturdy sealed bar which empties the water directly into the tank. The computerized system allows programming by inverter a microoscillation (“swing”) above all on straight, thick fl at edges to increase the work speed and improve the degree of polishing. The abrasive discs used are 130 or 150 mm in diameter.

BEVELLERS
Mounted in opposition at 45° angles, they make a double bevel on the straight edge using a 130 mm diameter abrasive disc. The first pair of bevels has a mechanical stop for the use of diamond tools.

TOUCH SCREEN
Allow to manage all the functions of the machine. In particular it is possible to program the entrance and the exit of each unit to ensure quality and precision on all specific working. Are allowed the partial workings (Optional).

ROLLERS
The machine is equipped with two, 1-meter rollers, one at the entrance and one at the exit, respectively. Each roller is equipped with side rails to prevent the piece from tipping.

TANKS
The machine is equipped with several stainless steel water collection tanks to maintain proper functioning and the duration of individual components.

GUARDS
The external casings are in sturdy fibreglass while the pressing bar and the single unit guards are in stainless steel.
