I work in an engine factory where we grind all of our cams and cranks. Although the systems are mostly automated for higher productivity, the principals are still the same. Clean centers, perfectly dressed wheels and coolant. A gantry loader/unloader handles the parts and inline gauges check diameters and send real-time comp data back to the machine. The operator runs all the surface finish checks and one of every 10 goes to the CMM for complete inspection. We do 60 crankshafts per hour, or one a minute.

Cubic Boron Nitride is a hella win compound. Runs cooler, is harder than other abrasives, superior chemical stability (does not evaporate or absorb into the steel like diamond can do), produces better finishes, has an extremely long life, etc. And its just amazing its made from a gas and a brown powder.

Hey everyone just putting some background in the world of comments. I’ve done some quality work on pieces that were going to to a portable quadrupole mass spectrometer and we needed metal conical inserts at 3 places to reduce airflow with specifications for exit flow within 5 milliliters per hour with an inflow pressure of around 1 bar. Specifications and standard operating procedures are a complete must for any operations aiming close to your his type of standards. Some of our manufacturers were unable to deal with the standard operating procedure as the cleaning and packaging step made it so these nozzles couldn’t even go into a plastic bag as some of their off gassing vole tile chemicals would interfere with the finish. Thank you every single machinist out there that deals with engineers like me and the details we barely provide yall

They got some parts that were indeed held to. 0001. Just for fun I set a goal of holding .00005. One of my parts actually hit a full .00005. the rest. 00002+.00003. plain Okamoto, aluminum oxide wheels. Retired now! I scrapped a few parts over the years but it was never a machine issue. It never took more than I asked not once!!!

I'd size them very carefully and mark the tops with red sharpie marker. Then i'd load of 24 (3 rows of 8. Putting a +.0005 in the mix with red and, also a + .0002. I'd grind till I hit the+.0005 then dress the wheel very lightly. Mark the top again sneak down to pick these up then let the Okamoto do what it does best, and drive it down to size. Zero stress.

I run a S31 and a S33. Best finish I’ve had with our 80grit wheels is 2.7. We often have to get below 4 for match fitting. Very challenging to get that low without burning and hold a .0001 diametrical clearance to mating part. We also have some nickel seals we grind where we hold the finish between 28-32. I find that harder to hold a specific finish consistently on a 100 +pcs. Especially one so rough on a grinder.

Chris remember Your formula for part speed is approxamately 100SFpm, so a 4" part times 3.1415" equals 12.5" inches or about 95 rpm. your part looks close to 3 inches so 3" X 3.1415= 9.5 sf inches 125 rpms would be approx 100SF. I think you said 115 which is close enough. Also note that if your arbour and driver are out of balance (They are running out) that can lead to out of roundness and a bad finish too.

It would also be risky if i make a fault because i am at the end of the producing chain. So i try to stay on the "save" side of speed. ;-) For me it was a pleaseure to see that you baught an "expensive" swiss grinding machine.

Is this RA in an different scale? I daily grind piston pins (big, for trains, power plants, ships etc), and grind them to Metric Ra ~0.20-0.10, before finalizing lapping. Not always easy finding dressing parameters that allows for both grinding-speed and surfacefinish, and part cylindricity, while also no deep scratches are allowed (of which most wont go away with lapping). Some models we make have cylindricity of under 4μm metric AFTER lapping
