Rod and Crank system ram drive
TECHNICAL SPECIFICATIONS
MACHINE STRUCTURE
manufactured from electric arc welded sheet metal of robust thickness, adequately ribbed and heat treated for internal stress relieving.
HEAD and RAM
G30 cast-iron. The head travelways are ground and hand scraped to ensure perfect ease of movement of the ram. The ram is driven by a self-braking asynchronous motor, reduction gear unit and crank assembly. Ram travel (stroke) is manually adjusted using the cam on the handwheel. The head tilts 20° both clockwise and anti-clockwise and is the ideal solution for machining conical slots.
RECTANGULAR TABLE
quality grade cast-iron with ground and scraped travel guides. Wide central hole to floor designed for machining long shafts.
TURNTABLE
quality grade cast-iron with wide central through hole designed for machining long shafts. The travelways on the table and support are ground and hand finished. Table rotation is driven by a worm screw-sprocket assembly (the worm screw is steel quality 18 NCM 5 hardened and ground and the sprocket is bronze quality B14) which incorporates a micrometric backlash recovery system. Maintenance free support guide thanks to an automatic greasing system. Computer controlled compressed-air driven rotation lock system during machining.
AXIS
tables with NC controlled axes are moved by ground and enclosed recirculating ball screw assemblies.
LUBRICATION
a timer controlled pump lubrication system. When the oil level drops below the minimum level machining stops automatically and an alarm prompt is activated.
COOLING SYSTEM
closed circuit system driven by a centrifugal electro-pump and a removable swarf collection tray is positioned below the table for easy access.
sheet metal and Plexiglas folding enclosure with front panel doors for easy access when the overhead crane positions the workpiece.
Microswitch safety feature, in conformity with safety directives in force, is fitted to the enclosure to prevent opening during machining.
ELECTRICS
Each axis is driven by a brushless motor and servo-drive with NC control. The NC control system allows easy machine programming even for complex workpieces. Electrics and wiring conform to the stringent safety directives.
