MILLING
NPA 19/2021
A New Tool Family for Highly Efficient Rough Milling for Increased Productivity and Cost Savings
Highlights
The successful launch of the MILL4FEED milling line provides excellent results in rough milling. ISCAR introduces NEOFEED for high productivity milling which incorporates indexable double sided
inserts with 8 cutting edges.
The new NEOFEED cutters are available in the diameter range 50-100 mm in the following two shell-mill design configurations:
- FFQ8 -12 with 12° cutting edge angle for milling with extremely high feed per tooth (fast feed milling) at depths of cut up of to 1.5 mm.
- MFQ8 -12 with 22° cutting edge angle for milling with “moderate” feed (less than high but much more than common) at depths of cut up to 3 mm.
- When milling near a wall using MFQ8 D...-12 cutter up-milling is recommended.
The new shell mills carry the same double-sided square inserts FFQ8 SZMU 120520… with 8 cutting edges.
When mounted in a NEOFEED tool, the insert enables a positive tool rake angle which assures smooth cutting and reduced cutting forces and power consumption. The insert pocket has a dove-tail shape that provides rigid and reliable insert clamping and improves the cutter’s capability to withstand heavy load. These features provide increased cutting data for better productivity and for improving tool life.
The new FFQ8/MFQ8 D…-12 shell mill cutters feature a fine-pitch option for 50-100 mm cutters. This feature extends the range of application options for roughing specifically in the die & mold, aerospace, and general engineering industries.
FFQ8 SZMU 120520… Insert Features
- Double-sided square insert with 8 cutting edges.
- High-strength body structure.
- The specially designed 2.0 mm radius insert corner with reinforced cutting edge increases insert strength when milling near a wall.
- Available with two types of cutting geometries (T/HP) for optimal machining different materials.
- FFQ8 SZMU 120520... inserts are produced from ISCAR’s latest carbide grades with post-coating treatment technologies that guarantee greater tool life and higher productivity.
- The same insert fits the both types of the new cutters.
- An attractive economical solution due to insert cost effectiveness per one cutting edge.
FFQ8 SZMU 120520T - for steel, ferritic and martensitic stainless steel, cast iron and hardened steel (ISO P, K and H groups of application).
FFQ8 SZMU 120520HP - for austenitic stainless steel and high temperature alloys (ISO M and S groups of application).
FFQ8/MFQ8 D…-12 Cutter Features
- FFQ8/MFQ8 D…-12 A fine-pitch design for increased metal removal rates.
- Coolant holes directed to each cutting edge, for efficient coolant and improved productivity.
- Protective coating of a cutter’s body provides better chip flow and protection from corrosion and wear.
