Les, I'm a process manager for Anchor Abrasives Co, We custom manufacture Double disc grinding wheels, Centerless and Roll Wheels. We are located near Chicago.
I need to have some parts double disk ground to get some thin parts (knife blades about .160 thick) flat, parallel and finished nicely.
What is the material? Stainless? What are the part tolerances? Surface
Finish required?
I dont know anything about the process other than it is supposed to be able to do what I want. So please educate me!
2 opposed discs simultaneously grinding the part to size. See
http://www.cbmachinery.com/DiscGrind...S/Default.aspx
does the hardness of the material matter? I would like to grind after Heat Treat
Yes. A hardened blade requires a more friable abrasive.
what fixtures are used? Are they unique to each part?
Depends on volume and part size. If the volume is small you could use a
reciprocating fixture that would move between the abrasives. If the volume
is large than a rotary fixture (carousel) would offer better production
rates.
what kind of finishes do they usually get outta the machines? is there a standard?
Depends on the grit size of the abrasive. An 80 grit wheel for instance will
get about a 15-20 micro finish on a hardned blade. Finishes can be reduced
to half that if necessary by changing grit size of the abrasive.
What else should I be asking?
We could recomend a good shop if you need one.
