I have recently acquired a couple of old Face Mills with indexable inserts. I don't have any previous experience of working with this type of cutter. One is a 125mm 6 insert type, the other is a 3 inch dia. 4 insert type. They are probably obsolete as far as the manufacturers are concerned, but it seems a shame to scrap them if they can be made to work (goes against the grain).
The inserts are marked SECO S25K on the 125mm dia. one. They are for a face milling head manufactured by Walter,
The other head has inserts marked Ste S2F.
The insert marked SECO S25K is a double sided "flat ended" triangular one with no hole about 22mm side and 4mm thick.
The one marked Ste S2F is a triangle about 21mm across with a chip breaker and 5.5mm dia. hole.
There are no other markings at all. Does anyone know what these are and if they are still obtainable, and if not, is there a suitable substitute available?
Whilst I appreciate that there are different inserts for different materials, angle of approach, types of cut (e.g. finishing, roughing), chip breaking etc. how critical is it to get absolutely the correct original insert?
Also are there any specific instructions or tips available on how to align these cutters? I assume that the inserts must be very accurately aligned at the tips to get the best finish.
Thanks
Tony
