BRIDGE TYPE MILL, DRILL CNC WITH RIGID TAPPING CAPABILITY

We specialize in custom-built machines in metal cutting. We offer CNC controlled SGPMs (Special Purpose General Machines). The machine that is being showcased is a custom-built machine, but is capable of doing all milling, drilling operations, apart from rigid tapping. It has a stationary bed, on which the table moves longitudinally (to and fro).

• The machine is suitable for milling and drilling upto Ø 50 mm in 2250 mm long x 1250 mm wide x 25 mm thick plate with in-built rigid tapping capability.
• Working height: 600 do 700 mm
• Ram type drilling head with ISO-50 spindle; ram stroke to form the vertical axis.
• Ram: 250 mm square, having 350 mm vertical stroke
• Daylight: 500 mm
• Powered arbor clamping, declamping system
• Provision for external or thru- coolant (with geared pump), capacity: 40 bar/40LPM
• LM/hardened & ground guide way strips for male sliding surfaces, turcite for female sliding surfaces.
• Ball screws & nut for all the 3 axes
• Metallic, collapsible guide way covers for the table; bellows for the cross and vertical axes.
• Machine enclosure, if ordered
• T slots provided on the table to facilitate mounting of any type of fixture.
• Lapp cables
• Screw type chip conveyor
• Drag chain for cables
• Coolant filtration for 15 microns
