Hello from Norway

Hi, my name is Vidar and I'm from Norway. I'm 58 years old and completely new to turning and milling. I acquired an Optimum 1000 lathe and a small milling machine three years ago. I worked in the oil service industry for 35 years, specializing in servicing and maintaining Blowout Preventers (BOPs), which can weigh up to 450 metric tons and require precise measurements. I came across this website while looking for tips on how to make a tool grinder for mainly end mills, as I have access to used and damaged ones from work and wanted to find a way to make use of them.

Welcome Vidar ! Whilst there are full service tool and cutter grinders like the Quorn and Stent, you don't really need anything so fancy if all you want it for is end mills. I'll see what I can find for you.
Cheers

Thank you Peter, that would be grate!

Years ago an old school machinist told me "It's an end mill, use the end!" To that end there was an article in The Home Shop Machinist in one of the earliest issues on building a simple attachment for sharpening the ends of end mills. Try looking through their on line index for it. as I recall it was a bracket mounted on a 6 inch grinder that supported a pair of cylindrical rails that in turn supported a mandrel holding the milling cutter. A peg was screwed into the mandrel that limited rotation to exactly a half turn. Finally a screw adjusted stop controlled the depth of travel. Lastly the mounting bracket set the assembly to give a slight "wing" angle to the cutting edges. The diameters and spacing of the parts were such as to give a simple geometric relationship. As a hint the rod from a shock strut provide precise chrome plated material for this project but Do Not try to machine the spot welds off, use a grinder. Once you can get under the chrome plate the rod machines nicely. Good luck from Bill in Boulder CO USA

Lucky lucky lucky to have access to broken or used tools.

In a similar situation I find it easiest to do most of the work free-hand with a skinny disk in an angle grinder - especially where you find a really knackered one, and have to cut 10mm off and start again with all the back relief etc. Then your sharpening fixture is only needed for the important final step of getting the 2, or 4, teeth to the exact same cutting height and angle, so they all do some work. It's good to practice with big ones (1/2" dia and more) where you can actually see what you're doing and think about the angles you are trying to grind in. I bought a Chinese 'U2' grinder very cheap, 2nd hand, which is a version of a 'Deckel' grinder. If copying it, the design is quite good in that you only have to create accurate pivots which clamp, not slides, and it all works on round bar not dovetails and gib strips. Well, perhaps worth considering. As a 'half-way house', the clever bits (tool holder with multi degrees of freedom) are on UK ebay for a lot less than the full machine.
