Tried these instead of my regular brand, and saved a lot. Results were just the same, with a superb finish on aluminium, and a great result turning Acetal and Delrin too. Very pleased.
Leaves very nice surface finish even with dry machining of aluminium. Also perfect for machining plastics.It is possible to remove 0,01mm layer when machining plastics (DELRIN)
We carry out line boring with a Sir Mecannica WS1.Its a tricky operation at best .Could not get the inserts from normal supplier.Also original ones were expensive,these were cheaper so I had my doubts they were up to the job.They were fantastic! Uninterrupted cuts & hard spots in the bore. Just bored out a JCB robot only used 1 insert! A good finish (see west knighton engineering on face book)
I am now using these very sharp inserts instead of the usual allround inserts for black and inox - all the time. There is no minimum chip size when turning with these inserts! And at the same time I often turn up to 5mm. chips - yes also inox... Lastly the non existing chip turning pressure minimizes vibrations and the energy required to turn the chips:]
Very good inserts. Cuts aluminium like butter and leave fantastic finish. Also works very well on "gummy" hard to machine materials like 5252 aluminium and mild steel. Doesn't require high RPM and agressive feed.
