Application:
-
For long work pieces (8 to 30 meters in length), which require machining operations only at the end of the work piece
-
Typical usage is for milling, drilling, and tapping of long I-beam & H-beam made of structural steel
Basic Design:
-
Rigid, heavily ribbed, stress relieved grey cast iron structure conforming to IS:210
-
Machine bed, telescopic sliding guide way with bellow cover protection, vertical single column moving on machine bed
-
All the slides are driven by lead screw, coupled to worm reduction gear boxes and AC induction motor.
-
Slides are made of cast iron sliding surface and driven through either lead screw / phosphor bronze nut OR rolled ball screw. The bottom slide moves in longitudinal direction.
-
The column carries the cross-travel guide way with bellow protection, spindle head and drive. A Milling Head is mounted on top of the slide. The rotating spindle carries the tool holder and milling cutter.
