A New Tool Family for Highly Efficient Rough Milling for Increased Productivity and Cost Savings

Highlights


The new NEOFEED cutters are available in the diameter range 2.00”-4.00” in the following two shell-mill design configurations:

• FFQ8 -12 with 12° cutting edge angle for extremely high feed per tooth (fast feed milling) at depths of cut up of to .059”.
• MFQ8 -12 with 22° cutting edge angle for milling with “moderate” feed milling (less than high but much more than common) at depths of cut up of to .118”.
• 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 dovetail shape that provides rigid and reliable insert clamping and improves the a cutter’s capability to withstand heavy load. These features provide increased cutting data for better productivity and for improved tool life.

The new FFQ8/MFQ8 D…-12 shell mill cutters feature a fine-pitch option for 2.00 - 4.00” 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 .0787” 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.

Cutting data
The recommended cutting data are shown in the tables in the last pages.





FFQ8-12
Fast Feed Face Mills Carrying Double-Sided Inserts with 8 Cutting Edges • Radius for programming .142"
• To generate a straight surface without cusps, the width of cut most not exceed DC
• For slot milling or machining with high tool overhang, the maximum depth of cut should be reduced by 30%
(1) Cutting diameter maximum
(2) Number of inserts
(3) Maximum ramping angle
(4) For interpolation
(5) For interpolation
(6) Master insert identification





MFQ8-12
Moderate Feed Face Mills Carrying Double-Sided Inserts with 8 Cutting Edges • Radius for programming .197"
• To generate a straight surface without cusps, the width of cut most not exceed DC
• For slot milling or machining with high tool overhang, the maximum depth of cut should be reduced by 30%.
(1) Cutting diameter maximum
(2) Number of inserts
(3) Master insert identification






FFQ8 SZMU
Square Double-Sided Inserts with 8 Cutting Edges for High Feed Milling • For side plunging, the initial cutting feed is 0.1 mm/t
• T- for steel, ferritic and martensitic stainless steel, cast iron and hardened steel
• HP - for austenitic stainless steel and high temperature alloys.


Averaged cutting data for FFQ8 fast feed cutters
* ISCAR material group in accordance with VDI 3323 standard
** Quenched and tempered
For machining in unstable conditions, the recommended cutting data should be reduced by 20-30%.
