Hello,
A while back, I posted a few questions about grinding. The company I work for is bringing work in house, and we will be starting to do grinding on cutters that will get stacked onto shafts. Based on that thread, I came to the conclusion that a blanchard grinder would be best. The company purchased two used surface grinders. LOL Then they purchased 2 old blanchard grinders.
Anyway, we just received the first of the two surface grinders. A Chevalier FSG 1224 AD.
I did get the electrical and operation/maintenance manuals with the machine.
I've been put in charge of this grinding project due to my experience running manual mills and lathes, but I'm the closest we have to a machinist.
I understand that grinders are a whole other animal, and I know I'll get there. I can read the manual and get familiar with the controls that way. I'm really good at learning by reading and observational while doing, but I still have newb grinding questions.
1. For a hardened tool steel around 45 Rockwell, what is a typical amount for depth of cut? (my initial guess is .0005")
2. What about stepover?
3. What is sparkout? (The old Chevalier manual looks like it was translated to English, possibly from Canadian French).
4. Is there a best method for balancing new wheels?
5. Ring test, does any wooden hammer work?
6. This machine is setup for coolant with the cooler/filter portion next to the machine. Any suggestions on coolant type?
7. Adjustable force electric magnet chuck. How do I judge how strong to make that? Is the only down side to a stronger setting the deflection of the material I'm wanting to grind being pulled flat by magnetic force, and then being warped when I release the magnet?
8. Other than a grinding wheel being defective and breaking/exploding, and running the wheel into a part that's too tall in a direction that would force the part under the wheel causing it to break, flinging parts off the chuck, and eye hazards, are there any huge safety considerations that aren't obvious?
I realize these questions prove my inexperience, but I'm trying to learn as quickly as I can at this point.
Thank you for any info or tips!
