the insert’s cutting edge
Use the formulas below or use our internet web tool at:
• For an insert with a width smaller than 2.2 mm, there
http://mpwr.iscar.com/machinimgpwr
are no standard catalog tools available. There are 2
options as to how to use these narrow inserts:
Turning
P = K ∙a ∙f∙v c [kW] 1 Modify an existing tool and adjust the support
p
c
under the insert to the required width

h∙ 60,000

2 Use a standard M-type tool without support
• In wider widths, there are also cases where the support
R under the insert will disturb machining (threading inserts,
pulley-V inserts and various specially tailored inserts) and
therefore the above explanation should be considered
W • These tools also provide the option for
customers to use a very wide range of insert
widths on the same tool (up to 6.4 mm)
f
ap f • Machining conditions need to be light due to
little support and limited gripping forces
