Typical Applications

Keyway cutting, slotting, and end milling on shafts, couplings, gear blanks, and similar components.
Slotting, pocketing, and facing operations on pump housings, motor casings, and medium-sized castings.
Machining of flat surfaces on dies, fixtures, and welded fabrications in heavy workshops.
Repetitive vertical milling operations in cement, power, and railway maintenance shops.
Workshops requiring a robust single-axis vertical milling solution without multi-face complexity.

• Knee-type vertical milling machine intended for straightforward vertical milling, drilling, and slotting operations.
• Rigid knee-and-column construction using stress-relieved FG-260 grey cast iron to provide damping under axial cutting loads.
• Case-hardened and ground alloy steel spindle and headstock gearing, suited for sustained vertical milling duty at low to medium speeds.
• Powered feeds on all three axes via servo-controlled drive, allowing smooth and adjustable feed rates during extended cuts.
• Simpler and more direct machine architecture than universal milling machines, preferred where angular or multi-face machining is not required.
• Well suited to maintenance and production-support workshops where durability, repeatability, and ease of operation are important to the user.
