- The entire machine is built from electrically welded steel, which prevents any deformation from occurring and assures excellent resistance to all types of stresses. Surface treatments included painting and sanding with rust inhibitor and bi-component epoxy paint, highly resistant to atmospheric agents.
- All parts are galvanised, where possible, so as to enhance both the aesthetic quality of the finish and resistance to corrosion. The same applies for the nuts and bolts, which we also supply in stainless steel on request. All guards are made of stainless steel to assure a longer life.
- The machine comprises a galvanised tank for draining water and expelling the various fragments of material.
- The spindles bearing the abrasive tools are inserted in a bored monolithic structure; this assures a centesimal parallelism in relation to the workbench. The sliding surface of the bench is planed to ensure a perfect 90° angle in relation to the abrasive polishing heads.
- The presser bar is motor-driven and guided by three chrome-plated steel supports so that its weight will not be completely borne by the lifting screws.
- Other types of machining processes can be performed in addition to edge polishing; these include profiling of the bottom groove known as the “drip”, the top groove for the sills of windows and doors or other masonry openings, or calibration, reverse polishing and front edge cutting. The blade cutting device for the upper groove can be inclined by 45° so as to permit bevelling.
- All of our models are supplied complete with a workpiece support bar, which becomes a rest for long strips; on request this bar may be motor driven and its movements controlled by limit switches.
- The abrasive tools for polishing edges and bevels start up automatically as the workpiece passes before them and stop and move back once the operation is completed.
- All of the edge and bevel polishing wheels can easily be switched in and out of the processing cycle via an electric selector switch on the control panel and, like all of the other machine tools, via the start and stop buttons.
- The conveyor belt is guided over the drums and the sliding surface by means of a small belt welded inside it; motion is transmitted by a gear motor controlled by a vectorial INVERTER; speed can be adjusted from the Control Panel, enabling the operator to choose the optimal speed according to the thickness of the workpiece.
