M370 Cutting Data • WO..08
First choice starting feed (fz) is in bold type.
Use corresponding speed (vc).
fz and vc are valid for ae ≥0,4 D1.
For smaller ae, fz and vc should be multiplied by the factor given below:
ae/D1 = 0,2 0,3 0,4
fz-Factor 1,5 1,3 1,0
vc-Factor 1,3 1,2 1,1

M370 Additional Application Advice
Copy Mills • M370 Series
Applying High-Feed Tools
The high-feed concept bases its strategy in small depth of cut and
higher fz values, which result in a higher MRR and productivity
with low radial forces.
L/D ratio starting Ap1 starting fz range
<3 0,9mm 1mm–1,3mm
>3 to <5 0,6mm 1mm–1,3mm
>5 to <7 0,4mm 0,6mm–1mm
Recommended when long overhang
is necessary due to lower radial
forces. Maximum L/D ratio of 10 x D.
Cutter
Diameter
Hole
Diameter
Rt t Wt
2,5mm 1mm 7,5mm
For CAM programming, the tools can
be programmed as a toroidal tool type
by using the Rt value as the insert radius.
Small Ap1 values and higher feed rates
generate lower cutting forces versus
traditional milling strategies.

material groups depending on their actual conditions.
Material Groups and Condition
AG — Aged
AU — Austenitic
BF — Heat treated to specified strength
BG — Heat treated to specified microstructure
BY — Heat treated to improved machinability
DU — Stainless steel duplex (austenitic-ferritic)
FE — Ferritic
G — Annealed
GG — Grey cast iron
GGG — Nodular cast iron
GO — Cast
H — Hardened
MA — Martensitic
N — Normalised
NAG — Non-aged (non-aging)
PH — Precipitation hardened
S-AU — Superaustenitic
U — Untreated
V — Heat treated
var1 — Variable
