with such tools, for roughing, on a recent setup, i machined clasic olc45 steel : cca17000cm3/wnmg_insert
that is 17000/6=2850cm3/insert_edge i don't know if this is good or bad, but for me is ok
Hello good design should allow an insert to cut without actually clamping the insert on the holder
in attach archive is a movie showing it : insert is put in place by hand, and it cuts @ 2000o/min x 1.5mm_radial_depth
after cutting, turret raises and insert falls down
tightening an insert on such a holder must not be done thinking that delivered torque must overcome the cutting forces, but only to keep the insert in place, not to fall because of gravity
i use kyocera for turning, and in attached images you may see holder specification and clamp design
the clamp mechanism uses a single screw to lock & drag the insert, thus there is a single section with effort inside the insert, and this effort is not great if normal tightening occurs
about the main screw : if the hexagon of the main head is damaged, the hexagon at the opposite head may be used : no downtime
when using holders from other producers, i noticed that insert and/or shim raises, when insert is clamped
this does not mean that kyocera is the best i am not here to sell kyocera ...
i only wanna say that kyocera turning holders look simple & robust, and kyocera printed catalogue has quality paper and really nice colors, not like the images from the pdf
i hate when trees are cut to make catalogues and low quality furniture ... kindly !
