Model 150 1AC Slotting Machine

Machine Information

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 (for models  1AC / 2AC): quality grade cast-iron with ground and scraped travel guides.   Wide central hole to floor designed for machining long shafts.

TURNTABLE (for models  1ACT/2ACT/2ACTM/3AC/4AC) : 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.

LONGITUDINAL (axis Y) and HORIZONTAL AXES (axis X):  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.

SAFETY PROTECTIONS AND FEATURES:  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.

1 NC controlled axis (axis Y) + 1 manual axis (axis X)

Pre-programmed and reversible longitudinal slot machining and tool lift obtained by  alternating  table  movement.  Once the pre-programmed slot depth has been reached, in automatic the machine performs a number of finishing strokes and the ram stops in its top position and  the workpiece table  in automatic returns to machining start cycle position.   Workpiece table  with central through hole.  20° tilting head (in both directions).  Inverter controlled  variable stepless slotting speed with potentiometer incorporated in the control panel.   The machine incorporates an electro-pump for the tool cooling system and vacuum pump operated  ram and trolley lubrication system.   Maintenance tools and machine instruction manual are provided.
Machine designed and manufactured to EC standards and directives.
