A Very Inexpensive Way To Sharpen Brazed Carbide Lathe Cutters

[Bamban]

just came in yesterday a 4" diamond coated wheel from http://www.banggood.com/100mm-4-Inch-Diamond-Coated-Grinding-Wheel-Grinder-Silver-Tone-p-929663.html $2.79 free shipping have not tried it yet though. I wanted to use it for tig rod and for carbide and wanted to take an old insert and grind it down for a scribe on my height stand.

Thank you for the link, I can make a mandrel for it and use my 9z20 to learn how to grind the cutters.

Of course this post has been up here for a few and I'm glad I found it. I recently bought my first set of carbide insert tools and have been a little reluctant to "stick 'em in the machine" and give them a go. After reading these post I feel more confident on there proper use.
I just bought my second lathe a South Bend CL 175 c, 13" I hope it will spin fast enough for these carbide insert cutters.
Thank you to all for the good information.

Thanks all from me too for the info in this thread. I've been trying to improve my sharpening skills lately and just built a new workstation/cabinet for my grinder with two nice slotted tool rests. Been thinking about some sort of diamond wheel setup myself, but my needs are more for carbide-tipped router bits. I'm noticing a bad habit I have of using dull ones and my "slide them along the edge of a diamond sharpener a few times" method is too random and proving to be ineffective.

I was thinking that maybe some sort of collet block in my mini mill vise would force them to land at a perfect 180° when you flipped the block over, and put you at the same spot on the opposite flute. Then you could bring a wheel down like the OP does, or slide the table across one with the feed wheels. Has anybody rigged up something similar for when multiple matching flutes are involved?

Thanks!

What a great thread full of info and good ideas

Great ideas, I wish I was more creative! I like to see all the hf adaptations that save money and work well.

Great ideas!!
I really like the lil saw blade sharpener with diamond wheel.

I thought this was a new idea but a lot of you guys have been all over it before me

I never would have thought of this idea thanks!!!

I made a couple small carbide grinders didn't cost a whole lot to make and they work very well. I made them for touching up carbide drills and carbide inserted lathe tools. Here is a video showing it

Very cool
great use of spare parts!!

I know I'm new here and don't want to make anyone uncomfortable because they didn't think of it sooner, but if you are sharpening lathe tooling and are looking for something to turn the diamond or carbide sharpening discs or stones...you probably have a tool to do just that already. Your lathe has adjust adjustable speeds, right? Just turn a mandrel to hold your disc or stone and put it in your lathe! Most probably you have the vices or tool holders to get the correct angles for your cutting edge.

Please tell me if I am wrong or that the lathe shouldn't be used for such a procedure. It's something you already have. It won't take up more room on your bench or in your cabinets. It probably has good lighting and gives you another reason to depress the power switch to hear the motor turn! Maybe, just maybe you could even make another jig to hold your dull saw blades and another to hold your router/shaper bits. I have always thought lathes were so handy. I cannot wait to finally get started seriously using mine!
