Specs per the manufacturer:

The automatic edge polishing machine LF12T has been specially designed for the continuous production of straight, gauged, regular bull-nose, bevels and grooves.

The conformation and polishing is carried out in one single automatic operation managed by the PLC, by placing the material on a conveyor belt and going through a sequence of gauging, pre-shaping, polishing, beveling and cutting spindles.
Generator spindle motor power 2,2 kW/3 HP
Polishing spindles motor power 1,5 kW/2 HP
Beveling spindles motor power 1,5 kW/2 HP
Cutting spindle motor power 4 kW/5,5 HP
Belt motor power 1,1 kW/1,5 HP
Belt speed 0-1,5 m/min

Pre-shaping spindles

Pre-shaping of the bull-nose and other round forms (half bull-nose, pencil round etc.) are carried out by two diamond wheels, mounted at 45°, with direct transmission, pressurized and positioning with manual blockage.

Polishing spindles

A group of a flat diamond wheel, with automatic positioning and pneumatic blockage, and seven spindles with pneumatic work pressure carry out shaping and polishing of bull-nose and other round forms (half bull-nose, pencil round etc.).

Beveling spindles

For pieces that require beveling superior and inferior sections, there are two spindles with direct drive, pneumatic work pressure, and pressurized to avoid water and dust entrance.


On an electro-welded steel structure with grinded support plane runs the synthetic conveyor belt with a guide that avoids the lateral displacement, driven by a motorreducer with an electronic speed control. The material is transported by polyurethane rollers with stainless steel axes and, for big dimension pieces, there's a mobile bar with plastic wheels and entrance-exit benches with acetyl resin wheels and stainless steel axes. The structure has a material-support system with motorized anti-slip rollers.

Cutting spindle

For making grooves on the inferior, superior or on the edge of the material, there is a spindle for mounting a diamond disk with manual vertical, horizontal and angular motions.

Calibrating spindle

For grinding and gauging the thickness of the edge with a diamond cup wheel.

Can also shape different forms. It has vertical, horizontal and angular manual adjustments.
