H BEAM, I BEAM MILLING, DRILLING & TAPPING MACHINE

H Beam, I Beam Milling, Drilling & Tapping Machine

We have manufactured a 3 axes Milling, Drilling and Tapping Machine, which can be used to machine i Beams, H beams, Box beams and other steel materials. The 3 liner slides are controlled by worm reduction gear box – AC induction motor routed through vector VFD to obtain stepless speed variation from 30 mm/min to 1000 mm/min. All slides have a DRO to find exact position of the slides. The ram type milling head mounted on the vertical carriage has extra rigidity than conventional slide mounted milling head due to its square box design locked in with taper jibs.
