SEC-Sumi Dual Mill

DFC Type

■ General Features

SEC-Sumi Dual Mill DFC type is a general purpose, high

efficiency face milling cutter which uses an unique shaped

insert that delivers both cutting edge sharpness and strength,

to cover a wide range of applications from high efficiency to

finish milling operations.

Unique insert shape delivers both

cutting edge sharpness and strength.

■ Usage

Deep Shoulder Milling (2 or More Passes) Helical Milling Ramping

Notes:

1. For down-cut

S50C: ae=15mm or less

FCD450: ae=30mm or less

2. For up-cut

No restrictions.

* For other queries, please

contact us.

◎ ◎ ◎ ○

Suitable for face milling and shoulder

milling with a 90° cutting edge angle.

Insert indexing accuracy of the DFC type is not affected as flank wear

does not move pass the support face.

■ Performance

(1) Cutting Force

Same as competitors' single-sided cutters.

(3) Surface Roughness Better than competitors' products.

(2) Cutting Edge Strength Edge damage from heavy interrupted milling

Higher cutting edge strength than competitor's double-sided and tangential insert cutters
