CoroMill 690

CoroMill^® 690 is developed specifically for high-productivity 2D profile milling of titanium components. Inserts are securely fastened by iLock technology. By equipping every insert pocket with threaded coolant holes with nozzles for high pressure coolant delivery, you can apply maximum coolant where required.

Benefits

• High-productivity milling of titanium

• Fully controlled flow and pressure through threaded holes - either for nozzles or plug screws
• Insert- and cutter interface shaped for rigid location with iLock
• Unique end- and side inserts for optimum performance

Application

• 2D profile milling of titanium
• Edging and full slotting

ISO application area

Recommendations

Insert sizes: 10, 14 mm (0.394, 0.551 inch)

Pitch

Coolant supply

During cutting, the chips can be prone to sticking to the cutting edge. This means that the next cutter rotation is re-cutting the chip. By equipping every insert pocket with threaded coolant holes with nozzles for high pressure coolant delivery, you can apply maximum coolant where required.

This effectively eliminates the problem for a constant cutting edge performance. Supplying cutting fluid to all the insert pockets in the long edge cutter requires high pump volumes and pressure capability.

Product range

• Diameter range: 40–100 mm (1.500–4.000 inch)
• Coromant Capto® coupling, HSK or Arbor mounting

iLock™ interface

Locked-in precision, rigid and stable for a consistent, accurate performance. A key feature to the success of this cutter is its unique iLock interface. The problem with axial cutting forces is the Achilles heel for other long edge cutters, but the design of the CoroMill 690 provides the essential resistance to these forces.
The result is:

• Dependable secure process – reduced insert movement
• Increased feed
• Longer cutter-body life - axial support prevents bottom row breakage and chip jamming on second row
