CPMT 06 02 04-PF
ap = 0.1 – 1.5 mm
fn = 0.04 – 0.18 mm/r
Good chip control, primarily for boring steel.
Feed: 0.02 – 0.24 mm/r. Depth of cut: 0.06 – 1.8 mm.
Operations: internal turning, facing, profiling and back-facing.
Advantages: light cutting, positive geometry generates low cutting forces for boring deeper holes, thin-walled or unstably clamped components.
Components: with holes that require machining, where low cutting forces and high surface finish are necessities.
Limitations: depth of cut and feed.
General recommendations: combine with a wear resistant grade (GC4215) for best productivity. Consider cermet grades when surface finish demands are high and cutting speed limited.
Possible optimization: cermet grades.
CPMT 06 02 04-MF
ap = 0.1– 1.5 mm
fn = 0.04 – 0.18 mm/r
Good chip control above all in boring stainless steel and in HRSA materials.
Feed: 0.02 – 0.24 mm/r. Depth of cut: 0.06 – 1.8 mm.
Operations: internal turning, facing, profiling and back-facing.
Advantages: light cutting, positive geometry generates low cutting forces for slender, thin-walled or unstably clamped components. The positive geometry minimizes the tendency for smearing (built-up edge formation) leading to good surface finish and long tool life.
Components: general stainless steel components.
Limitations: depth of cut and feed.
General recommendations: ideal for use when surface quality (surface finish and appearance) is a priority.
Possible optimization: geometry PF in cermet grades.
CPMT 06 02 04-KF
ap = 0.1 – 1.5 mm
fn = 0.04 – 0.18 mm/r
Boring grey and nodular cast iron.
Feed: 0.04 – 0.20 mm/r. Depth of cut: 0.09 – 1.8 mm.
Operations: internal turning, facing, profiling and back-facing.
Advantages: light cutting, positive geometry generates low cutting forces for slender, thin-walled or unstably clamped components. Leads to less frittering when turning over drilled holes. Even surface quality.
Components: cast iron components in general.
Limitations: limited application area - depth of cut and feed.
General recommendations: combine with a broad, reliable grade (GC3215) for best productivity.
Possible optimization: PF in cermet grades.
