  • CBN Grinding Wheels

    Has anyone dealt with the EBay vendor 'carbide_diamond_tooling' for the purchase of CBN wheels? If so, your vendor experience and product evaluation would be appreciated.

    Any other recommendations of sources of 4" CBN wheels? How about grit sizing for re-grinding HSS (lathe tools, reamers, taps, etc.) tooling??

    Evan is pretty well "into" CBN wheels as well.

      cannot say anything good about the first,

      but Evans wife sold me a couple of wheels, good price great service.

        Why CBN for HSS?

        99% of my lathe tooling is HSS and all I use is a Norton white wheel.
        Can't remember the number and I aint goin out to look, it's too damn cold!

        The white wheel cuts fast, clean and cool, with a beautiful finish on the tool. A quick tidy up with a diamond hone (the type you get in fishing/camping stores) and you're all set.

        A lot of my work is 316SS and other "obstinate" alloys.
        No prob with a sharp HSS tool and flood suds.

          The primary use for CBN wheels if to sharpen HSS to an accurate profile or dimension. The wheel doesn't wear very quickly and will maintain the desired dimensions when grinding to a specific shape and size. This especially applies to fixtured and CNC grinding of tooling.
          BTW, my wife is not at work today. She will be back on Tuesday.

            Sure Evan, I can understand jig grinders for CNC qualified tooling to ISOxxxx, just can't see the point for HSM or small shop use, even if it is CNC.

              I have two general questions:

              1. When comparing AlOx, CBN and diamond grinding wheels; does CBN and diamond remove material faster and/or cooler than AlOx? (on e.g. HSS tools)

              2. Are the pink and pale blue grinding wheels also AlOx? And are they any special compared to the white ones?

                Ive got a diamond and a CBN in 5" cups from CDCO and I am just amazed at the difference it has made in the upkeep of my cutting tools.

                My primary reason for the CBN at the time of purchase was getting around the mountains of that horrible grit that seems to be jet propelled off the AO wheels, - and not having to dress the wheel. Since I have been using it not only have I practically eliminated the dust/grit problem, but have been amazed with the use of it in the overall dressing of the tool, just much simpler, quicker,- youve always got that crisp sharp edge to work with.

                When making up a new profile on a HSS lathe bit, I'll do the rough-out of the shape on the belt sander or the 4" hand grinder and then do the finishing shape on the CBN.

                Diamonds the same way with the difference between a green wheel and it ... just another whole way to dress carbide.

                  The color of most wheels is a matter of decoration and identification within a particular manufacturers line of products. It has nothing to do with the actual intended use of an aluminum oxide wheel. AlOx is colorless so to make a pink or blue or whatever colour wheel dye is added when the wheels are pressed and baked. There are no industry wide standards for what a particular colour signifies. Each manufacturer uses a different system and many manufacturers also sell their products under off brand names that can't br traced back to the real name brand. It gives them a way to sell below spec product.

                    OK, thanks.

                    I suspected that really.

                      After six months of construction and spending hundred of dollars in materials to build a tool and cutter grinding system, the last thing I want to do is immediately eat it up with grit. The purpose of the project was to be able to get repeatable, high accuracy results. Descriptions of CBN virtues, posted to this forum, appears to fit the bill with regard to both concerns.

                        CBN just beats the heck out of any thing else. Cost a lot. but after you use it you want go back. And not near the mess. Best thing since white bread .

                          Question, can you use CBN dry? Just wondering, I have some used CBN wheels from work that were tossed when outside our specs for diameter. We normally use them to grind with coolant in a cnc grinder.

                            Whoa! have you been hiding this T&CG project?? Or did I miss it? You know this bunch is kinda fanatical about all grinders -with emphasis on the T&CG's.

                            Got pics??
