I have a production grinding job.
M4 annealed high-speed steel hot rolled plate. 1x1.5" blanks. Starting thickness 0.045. Ending thickness 0.030" +/-.001. Quantity is 5,000-15,000 per month.
I can outsource double-disc grinding. These machines are fabulously expensive used and I have no idea how to run them. Not terribly inclined to buy one, at least not yet. They are likely the machines best suited to this job.
I can buy a used Blanchard grinder for $10k and in-source the grinding. I don't know how to run one of these either but they seem common enough that figuring it out is possible. BUT can a Blanchard grinder reasonably hold material of this thickness? That's what I don't know. Maybe a steel cage 0.025" thick to hold/support the parts?
Automatic surface grinder. Cheaper than the Blanchard, but possibly slower and more labour intensive for the operator.
Any thoughts on this from grinder-hands? I am but a simple toolmaker who's never done any production grinding.
