Another Cutter Grinder

[Hawkeye]

Some years ago, I started to build a tool and cutter grinder, mostly with a view to sharpening endmills. I needed to make a rotary table to mill a curved slot, so I set the grinder project aside. I finished the RT, but never got back to the grinder. This is as far as I got. That's an R8 spindle, since I have a full set of R8 collets.


Today, I had a day off so I decided to make the grinder spindle. I figured an MT2 socket would be the most versatile in order to mount whatever I may need to spin as the project grows. I roughed the taper at around 1 1/2*, to be trued up with a tapered reamer.


It took quite a while to ream out the MT2 socket, but it came out quite nice.


I got to try out my new swing-up threading tool to cut the pre-loading thread.


The finished spindle. Next step is the body that the bearings mount in.

It's about time you started this one again. Been waiting since I started mine. :rofl::rofl: Keep up the good work.

Now with another thread on a cutter grinder build. The temptation to build one of these may be more than I can handle.

I am looking forward to this as well....subscribed!!

Brian;

Mike is an extremely gifted machinist. His work is impeccable. This will be a great build.

Awesome. I was showing some friends Bills thread. It's cool making parts and all. But when they see them parts go together to make a real live tool or machine, thats pretty dang impressive.

Then show them what a good one cost to buy, game over. ahahaha

I look forward to this thread and nice work so far.

Thanks, guys. Bill's giving me way too much credit. I'm glad this isn't a competition. )

Since I left the spindle in the lathe for the whole operation, I couldn't test fit the bearings. They ended up just a bit too 'slip fit'. I'll probably apply a light knurl to the bearing areas to plump them up.

Mike you can try a red or pink loctite to fill the void if it is not excessive.

Actually, for holding bearings on shafts you might want to try the green 609 (http://www.loctite.com.au/cps/rde/x...redDotUID=productfinder&redDotUID=10000009REW). It will work with light press fits and cover up to a 0.005" Gap.

I only mentioned the others for thoughts of removal later. The green has quite a grip

The grip comes from it's gap filling ability. It removes with light heating.
