Edge sintered inserts cut Al machining
costs
Inserts use the latest in sintering technology to improve metal cutting performance and reduce costs in applications involving aluminium and other light alloys.
Inserts used to machine aluminium and other light alloys require an extremely sharp cutting edge To achieve this edge manufacturers have had to resort to a time consuming, hence expensive, secondary grinding operation after the insert has been sintered

Cutters make light work of hard materials
Tool life when cutting hard materials up to 70 HRc is greatly improved, thanks to the development of a PVD-multilayer coating used on solid carbide milling cutters.
The development of a new grade (CWK 4625) and sintering process has allowed WNT to provide its F20 insert that can be sintered directly to its finished form, eliminating any need for grinding.
In addition, a recently developed surface treatment has also done away with the need for the top rake of the insert to be polished, a process that was required to avoid the possibility of swarf 'sticking' to the insert.
By removing these two, time-consuming, processes WNT said to manufacturingtalk that it is able, for the first time, to apply mass production techniques to the manufacture of inserts for machining aluminium.
WNT (UK) Business Development manager, Adrian Fitts, explained: "By removing the grinding and polishing operations from the manufacturing process, manufacturing time is reduced and greater consistency of the finished insert is possible.
In turn this provides greater consistency in use and, a significant cost reduction is achieved, which is reflected in the price paid by the end-user".
The F20 inserts have been designed to fit WNT's existing 2011 range of cutter bodies and the combination of new grade (CWK 4625), surface treatment.
The excellent geometry provided by the 2011 cutters is providing dramatically increased performance when machining aluminium.
Typically, speeds and feeds are up to 3500m/min and between 0.1 and 0.25mm/rev respectively at depths of cut up to 10mm.
And, with an emphasis on the machining of aerospace components WNT is offering the F20 inserts in standard corner radii of 0.2mm, 0.4mm, 0.8mm, 2.0mm and 2.5mm as standard. Request a free brochure from WNT (UK) ...
