CoroTurn^® 107 - wiper

CCMT 09 T3 04-WF
a_p = 0.3 – 3.0 mm
f_n = 0.07 – 0.3 mm/r​

A combination of high feed and good surface finish in steel, stainless steel,
cast iron and HRSA materials.
Feed: 0.05 – 0.50 mm/r. Depth of cut: 0.3 – 3.5 mm.
Operations: turning and facing.
Advantages: double conventional feed rates with the same surface finish or surface finish values that are twice as good for the same feed. Ideal for when a good surface finish is a priority. Can replace grinding operations. Improved chip breaking due to higher feed rate. Tool life is often improved due to more components per cutting edge and due to shorter cutting edge engagement time.
Components: stable axles, shafts, hubs, gears when good surface finish is a priority.
Limitations: can increase vibration tendencies in unstable components, limited function for profiling, lower cutting data when combined with cermet grade, visual finish often in form of a matte surface.
General recommendations: increase feed rate to maximum to achieve high productivity.
Possible optimization: geometry WM and cermet grade to improve surface finish even further.

CCMT 09 T3 08-WM
a_p = 0.7 – 4.0 mm
f_n = 0.15 – 0.5 mm/r​

High feed rates in steel, cast iron, stainless steel and HRSA materials.
Feed: 0.10 – 0.5 mm/r. Depth of cut: 0.5 – 4.0 mm (adapted to insert
geometry).
Operations: turning and facing.
Components: rigid shafts, axles, hubs, gears, etc.
Advantages: double conventional feed rates with the same surface finish or surface finish values that are twice as good for the same feed. Ideal when good surface finish is a priority. Can replace grinding operations. Improved chip breaking due to higher feed rate. Tool life is often improved due to more components per cutting edge and due to shorter cutting edge engagement time.
Limitations: can increase vibration tendencies in unstable components, limited function in profiling, lower feed and depth of cut when using cermet grades, visual finish often in form of a matte surface.
General recommendations: increase the feed rate up to double that of conventional finishing geometries to make use of the potential for shorter cycle times.
Possible optimization: geometry WF.

TCGX 11 02 04R-WK
a_p = 0.15 – 1.5 mm
f_n = 0.05 – 0.3 mm/r​

Primarily in boring operations but also external turning when low cutting forces are necessary.
Feed: 0.05 – 0.30 mm/r. Depth of cut: 0.15 – 1.5 mm.
Operations: turning, facing and profiling.
Components: especially unstable components, shafts, axles, hubs where surface finish is a priority.
Advantages: geometry advantage through combination of knife-edge and wiper, suitable for high feed rates on slender shafts, thin-walled components and unstably clamped components.
Limitations: depth of cut and feed rate, the need to select right or left-tool
alternatives.
General recommendations: combine with a more wear resistant grade (CT5015 or GC1025) for best productivity, consider cermet grade for high surface finish demands and when cutting speed is limited, open geometry may limit chip control.
Possible optimization: cermet grade.
