Engraving cutter sharpening

(1/3) > >>

chipenter:
I bought a set of ten tc engraving cutters from China , and have broken the tips from five so far , I made a simple jig to sharpen and put a relife angle on them , 1/2" Whit tread as it is turned in it puts the relife on , and any cutting angle is easely set , these are 20 degrees I hope these will last longer . 

awemawson:
A very neat idea using a coarse thread to create the relief - I must remember that one  :thumbup:

I'm looking over my copy of the Norman Tinker drawings and would be delighted to see more of it.

Perhaps you could oblige?

Thank You

John Stevenson:
Do not try to use these cutters as is from China they are far too sharp

You need to take a single swipe with a diamond slip angled back a couple of degrees and sideways a couple so you have less of a point, more the flat you get with your 12 degree attachment

TBH I still prefer HSS for fine work, far more forgiving

I was reliving the tip John but anything more than 0.2mm cut on brass and the tip went , 20 degrees gives a cleaner cut and the tip is still sharp , I will expriment further but still calling it a sucess .
