I haven't "killed" any of my annular cutters but they aren't cutting like they used to and like I know they should. Chips are finer, etc.

Before I do smoke one, does anyone have suggestions on a shop to send them to for sharpening that won't destroy the budget? Before I moved, there was a sharpening shop in Chesapeake, Va that was great and affordable. I asked the local Fastenal about their service and they said sure, we will get you the paperwork and they never did and now my local store just vanished with their last day open being last Friday. I have a Universal Tool grinder sitting in the corner that still needs to be wired up and setup and thats not one of the near term projects... so in the meantime...

Anybody use a mail off service?

How much of a project is the tool grinder? Fuck sending them out if you can do it in house, plus there are so many other things you need to sharpen anyway!
 
Any company that sharpens machine tooling can do them.


I also have a cutter/grinder sitting in the corner with all the jigs necessary to do this, but haven't found the time to clean it up and set it up.

Funny that arse likes your comment. No, a tool sharpener is not a project someone at home can do.

Of all the shops i worked at in wa state (boeing mfgr's) 2 of them could afford a tool sharpener. There are far more zero's after that decimal point on a grinder versus a nc machine. arse and firstram just showed their knowledge.

Again, wut?

A home gamer doesn't need a computer controlled anything to sharpen the handful of endmills or cutters that the average home shop is going through. There are sub $800 import Deckel knock-offs that are doing just fine for lots of people. And you can easily find an old KO Lee or Cinci cutter grinder for around a grand.

You can get this for around $700 from Amazon today...or under $600 if you ship it straight from China.

This is the little machine I'll be using if I ever get around to restoring it. I think I paid $300 for it.

We have a similar one at work. It gets used occasionally. But we're all a bunch of old farts in the shop.

I picked it up at an estate sale type deal for a retired machinist. His son was doing the sale and loved that I was buying stuff to actually use and not resell or scrap so he was giving me deals on everything and a bunch of free stuff. He practically begged me to take it and I think I actually ended up paying like $250 for it and he gave me two spindexters and a couple vises and other fixtures with it. No labels on it, but I managed to match it up to K.O. Lee A-600. Motor is silky smooth. Table is a litlle choppy - may need to just be cleaned or may need bearings. Should be an easy fix. I just want to do a full cosmetic resto on it and haven't even thought about it in the last 3-4 years. :shaking:

Only thing that didn't come with it was the table for the back side of the motor that lets you use it as a little table grinder. I think there's supposed to be a guard here too.....and I guess I'm mssing the guard for the front too.

This is the dumbest thing I've read all day, either you're very inexperienced or very stupid. Sharpening any tool is just holding the proper angle while you're grinding each facet, It's not that difficult unless you have no fucking clue about what you are doing. Have you seen the phenomenal work Alxj64 has been posting and do you think he can't set up an angle on a machine? When you send any cutter off to be sharpened, someone sets it up in a tool grinder to sharpen it. If you have the equipment and the aptitude, everything is attainable.

You should shut the fuck up and continue to pay someone else to service your lawnmower:flipoff:

Build a small RPC to run the thing because it has multiple 3 ph motors and I haz not teh tree faze and run all of my other stuff on VFDs. Went down the cost side of setting up a board with multiple VFDs but a very small RPC for this machine and also my slip roll would be better than the VFD route.

And once you get decent at it, you can probably set up a side gig doing it for others in your area. :idea:

Yeaaa... And I also have literally 1,000 lbs of HSS Punches and dies for Uni-punch frames that I can resharpen or resize for whatever I am up to.


This is the machine, its a B&S #13 Universal Grinder. Everything is there and I have an indexing fixture for holding NMTB50 tools and MT3 tools. I also have a plate where someone adapted a small Indexing Head from a milling machine onto a swivel base and to the rails of the grinder. I guess they were grinding splines into something very hard? Dunno but seems useful as I have a super small indexing head that fits it.

Its worth getting the thing up and running, but also I need these bits sharper sooner than later as they are slated for duty on some other builds this month.

^ you posted this while I was posting.

Phenomenal is a but of a stretch but thanks for pointing out my knuckles don't actually drag the ground as some might assume. I think that firing it up would be worth the time. Damnit, I guess this one gets to skip ahead like its fukin candy land in my shop. Ya'll talked me into it.

Maybee what i consider a sharp tool and what you consider a sharp tool are 2 different things.

Sounds like you need to sharpen your skills :flipoff2:
Tools are sharpened every day by people using tool and cutter grinders.

Are you implying that a CNC grinder of some sort is needed? I had a saw shop with CNC equipment grind one side of every tooth flush with the plate, on FIVE of my saw blades. I took them back and pointed out the problem and was promised they would make it right. The next week, I picked up FIVE re-toothed blades with the carbide ground flush with the plate:mad3:

CNC is great in turning human error type of failures into "computer dutifully doing something dumb" type of failures like that. :laughing:

I imagine you have no practical experience machining in a shop or a living, and use catch phrases liike arse to appear as though you know wtf your talking about. yt is hardly a place to learn machining.
 
Firstram said:
Obviously nowhere as long as you, with your perfectly sharpened annular cutters but, I have been to 2 county fairs and a goat fucking though.
We aren't talking aerospace equipment here. Get off your high horse:flipoff2:

When you dont know wtf your talking about, listen to the people that do.

That's not a teaching video. It's an AD I remembered seeing when I was sending cutters back to be sharpened.
