End mill sharpening

[RARanney]

Does anyone here sharpen their own end mills, and what is the procedure/equipment involved? Thanks.

I haven't yet sharpened any myself but you can buy the tool to do it with. Check out www.use-enco.com and MSC to mention a couple sources.

I used to work as a machinst and the tool room guys sharpened all the endmills in the shop. They used an indexing head on a tool grinder- a horizontal grinder with a diamind wheel. It is all about the angles. It'd probally be easier to buy new ones or send them out to get sharpened.

The enco one shows that you need a surface grinder to use it.

yes the ones made for the surface grinders
run I think close to $300.00 and up.
you can have a lot of them sharpened for $300.00
plus the grinder.

If you don't need to do any plunge cutting with it,sometimes you can grind the end off and relieve the center with an ordenary grinder and get some use out of it.But in general it's a wast of time = money and more econmical to buy new ones if you count your time as worth anywhere near min. wage.
