Paul: I meant to say that I can only do max of 0.25mm per pass. It always wow me when I see videos or photos of machines being able to do such a deep one (non Sherline), especially those turning videos. Didn't know its not metal :doh: All: can I grind those brazed on carbid tool? I've 2 pieces of left hand that were chipped sometime back. Couldn't bear to throw them away. Regards, Wong |

Yes, you can grind carbide, BUT you need a special wheel for it. If you try to grind carbide with an ordinary wheel that's meant for HSS, you'll just grind away the wheel and not the tool. :doh: |

You have the name of the wheel? |

Ask for a silicone carbide grinding wheel, theyīre usually green. See this http://www.rdgtools.co.uk/acatalog/Grinding_Wheels__silicone_.html I grind mine with a diamond cup wheel, bought it from RDG Tools several years ago, and itīs still like new. http://www.rdgtools.co.uk/acatalog/100mm_Diameter_Diamond_Grinding_Wheels.html Mine is the 2nd from top. Diamonds may be the girlsībest friend, but they are nice in the shop as well :thumbup: P.S. I use the diamond wheel ONLY for sharpening carbide tools. They will cut anything, of course, but HSS tends to clog the wheel, so it will appear blunt, which it really isnīt, but can be difficult to clean. |

Here's the only 2 pictures that are needed in my opinion: The black line near the tip is some built up HDPE plastic that I didn't notice when I took the picture. This tool is held in the cheapest, worst finished piece of Chinese cra..er..steel that I've ever had in my shop...but it works. :beer: It made all these blocks the same size within .002" in either direction. Not bad for a hand ground tool and horrible tool holder! again :beer: |
