Mold maker here, ive drilled and reamed a lot of holes. You can change the finished hole size by changing amount of stock left in hole. Bigger chip, bigger hole.
I attended a machine class in high school, and was working part time in a shop. Graduated ,went full time. They made stator winding machines and i was taught form grinding. These are some of the different shapes the wire wraps around.
I would make hundreds of those things,i soon got bored of it...
That looks like a nice grinder. Most of my day is spent in front of a surface grinder fitting mold parts. I wish mine had a lower Z feed like that one. When spinning core pins your arm is above your head all day.lol. Is that a wheel dresser mounted on the spindle?
I always keep the blade 1/4 the surface, you dont want to wear that down. as for the auger,that feeds the fan,or impeller that the blade or scraper, if ya wanna call it that, collects from your drive.
Hi Gregor, first time posting to this great thread. I have a tip that may help with close bearing fits. I have pin gauge sets at work, but with a lathe you can make a no go gauge to check your bore. I hope this helps in future jobs.
Does that one not have arms at all? Yes, has arms, first pic hard too see. And it did come with tall threaded extenders. so i could raise lower tires on blocks add extenders and raise. that would give about seven inches clearance between chassis and lift.
