High-speed Finishing for Grey Cast Iron

● High speed finishing cutter for Grey Cast Iron milling, that uses

removable cartridges for easy insert run-out

● Utilising BN7000 / BN700 grade with both good wear and fracture

resistance.

● Available in shell and small diameter endmill types.

■ Characteristics● High speed machining vc=2,000m/min

● Surface Roughness Rz=3.2 (1.0Ra)

● Safety structure for the centrifugal force under high speed cutting conditions

● Run-out is less than 10μm

● Easy assembly method using the setting gauge

● Running cost is reduced with economical inserts.

Milling of ductile cast iron and alloy steel casting do not produce the best results.

Dry cutting is recommended. Wet cutting will result in chipping of cutting edges in the early stages due to thermal cracking.

■ ApplicationFC250 to FC300 (200 to 250HB) Grey Cast Iron with Pearlite

matrix, and Ferrite matrix (HB130 to160) Application Examples:

engine block, cylinder block, etc.
