Application:
- For long work pieces (8 to 30 metres in length), which require machining operations only at the two ends of the work piece
- Typical usage is for milling, drilling and tapping I-beam & H-beam 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 is 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.
