Drilling & Slotting

Vertical Slotting Machine

All geared vertical slotter for internal keyway cutting and internal grooving in heavy-duty plant components.

All geared vertical slotter for internal keyway cutting and internal grooving in heavy-duty plant components

Typical Applications

  • Keyway cutting in large shafts, couplings, pulleys, and gears used in cement and mining industries.

  • Internal slotting and shaping of hubs, dies, pulleys, and gear blanks in steel plant maintenance workshops.

  • Defence workshops machining transmission components and specialised internal profiles where broaching is impractical.

  • Shipyard maintenance work, including re-machining of keyways on marine shafts, housings, and heavy assemblies.

  • Preferred in maintenance and heavy workshop environments where versatility and accessibility are vital considerations for the user.

Machine Description
  • • Vertical slotting machine designed for internal slotting, shaping, and keyway cutting on heavy and awkward components.
  • • Rigid, cast-iron machine body provides stability and resistance to the repeated impact loads generated during reciprocating cutting.
  • • Vertically reciprocating ram delivers controlled cutting strokes for internal features inaccessible to milling cutters.
  • • Circular rotary table with T-slots and 360° graduations, supporting indexed slotting and circular internal work.
  • • Provision for centering mandrel, enabling concentric internal slotting on round components.
  • • Direct indexing facility allows accurate angular positioning for multi-slot and spline-type work without complex attachments.

Configuration Notes

  • 1. Slotting machines are slow but versatile, suited for low-volume, repair, and maintenance-oriented work.
  • 2. Best applied where internal features cannot be milled or broached economically.
  • 3. Machine selection depends on job diameter, and internal feature depth and motor power, not stroke length alone.
