Universal Milling

Universal Milling Machine

Knee-type universal milling machine for flexible machining of prismatic components and fabrications with superior versatility and adaptability.

Universal milling machine with versatile swiveling head for multi-angle maintenance machining in industrial workshops

Typical Applications

  • Milling of machine bases, frames, and medium-sized fabrications in steel, cement, and power plant workshops.

  • Machining of castings and forgings in general engineering and mining equipment manufacturing.

  • Multi-face and angular machining using the swivel table for railway bogie frames and underframe components.

  • Toolroom and maintenance milling in defence and ordnance workshops.

  • General-purpose milling in heavy fabrication shops requiring flexibility across varied job profiles.

Machine Description
  • • Knee-type universal milling machine for flexible machining of prismatic components and fabrications.
  • • Rigid knee-and-column construction using stress-relieved FG-260 grey cast iron to provide damping during milling operations.
  • • Case-hardened and ground alloy steel spindle and headstock gearing, suited for sustained torque transmission in workshop duty.
  • • Swivelling worktable (±45°) mounted on a robust locking arrangement to support angular and multi-face machining under load.
  • • Powered feeds on all three axes via servo-controlled drive, enabling smooth and adjustable feed rates during extended cuts.
  • • Well suited to maintenance and general engineering workshops where adaptability is preferred over automation.
