RP3 con lo strumento di controllo sforzo e l’uscita dei pezzi di scarto
RP3 is a micro rolling machine for producing “micro” screws with a diameter ranging from 1 mm to 3 mm; in other words, all those parts known as “metal nuts and bolts” that are used in electronic boards and in the production of watches, bracelets and other small items. It has an automatic loading device especially for nuts and bolts, with interchangeable parts for measurement change, insertion of pre-calibrated parts, semi inverter speed variation, and millesimal adjustment on toolholder block advance (considering that the thread step is 0.25). New style tool-holder block: the 3 advance movements (longitudinal, vertical and transversal) are totally independent; the comb can be vertically tilted, with adjustment and fixing, and the whole block can be adjusted to increase or reduce the pressure as the screw begins rolling.
Pre-loaded introducer punch in both movement and thrust, to prevent false starts; guide support connected to the shaker-holder rack, with the possibility to make tiny adjustments to optimise the grip point between the guide and the shaker; the mobile comb-holder slide is pre-loaded, so is absolutely free of play (an essential condition to ensure all the screws come out identical and with the required tolerance values). The top quality and precision of the parts to produce is fully guaranteed. A jewel of a machine in terms of characteristics, quality and size.
