I work at a cnc aerospace shop and was wondering with the tens thousands of dollars we spend on buying carbide endmills... does anybody make their own? Is it cost effective?
Ryan 2 big shops I worked at many years ago we used to grind our own endmills mainly resharpen and specials.
theres a few things to consider.
#1 you need good tool grinders (machines)
#2 and most important you need a VERY GOOD TOOL Grinder, ( PERSON)
if your a grinding shop already like one was that I worked at for 10+ years it was no big deal. if your a CNC mill and lathe shop( like the last place I worked at) then get them made I think its more cost effective to have them made in that case.
Grinding your own drill bits is one thing but when it comes to endmills cutting high nickle alloys and other tough materials EXPERIANCE is a MUST.
the one nice about having a inhouse tool grinder is that when you need something you walk a few yards and get it done if it doesnt do exactly what you want it to do you walk again and have it done.
basically you can play till you get it right.
so theres pros and cons to both. bottom like is its not cheap.
