Take a look at two ways to grind a taper. The first way is a combo Master Grind / sine plate on a surface grinder and the second is using an OD grinder. Enjoy Don Bailey www.subtool.com

You often mention the importance of lapping the centers and doing it accuretly but I don't think you have done a video on just how that is done. I would like to see how, so how about a video on that? Would you take a MT reamer and clean that bore up a bit to get a better contact pattern?
@evildrome5 жыл бұрын
The bore will be hardened. You'd just wreck a reamer in it. I think it'd need to be reground.

Don, Since your taper is obviously off center when you start grinding and it was presumably not when the part was originally made (between centers?) the center and the threaded portion may be more likely to have moved during hardening than the tapered portion. Perhaps you should consider recentering the center and threads before grinding the hardened taper. With all due respect to your immensely greater experience to mine. :)

I like the way you explained. Grinding a tapper on a surface grinder needs a lot of experience and accurate attachments. The best part of all your explanation is "lapping the center's" both side. But I think their will be some ovality while grinding tapper on a surface grinder.

Nice work. Like you say in the machine shop there is always several ways of doing things. Often depends on what machines are available. I always have a tube of LibriPlate grease handy and put a dab in the centers to make the part run smooth and keep the gritty water out. I also put a squirt on the surface to be ground, surface or cylindrical, and that really helps to see the wheel sneaking up on it.

17:31 minutes in to the video, I understand your measuring how parallel the taper is in the longitudinal direction but I don't understand what you mean by a couple tenths What are the tenths a tenth of? Is the tenth you speak of a tenth of 1000th of 1'', in other words are you saying 100th of 1''? Do you mean couple 0.000010''?

What happens if you arent centered directly under the wheel. Seems to me you would have issues with the angle being off. Maybe your grinder has that 0 point?

Lapping by definition is stock removal with loose particles whereas grinding is with bound particles such as in a sand stone or an artificial wheel. For the rest I find it interesting to watch.
@TheWireEDM9 жыл бұрын
Grinding a taper is a hassle on an OD grinder, especially when the machines tailstock has worn down a bit. Sure you can get one part, but if the next part is not exactly the same length as the previous while sitting between the centers, it will be at a different angle due to the tailstock not pointing straight due to wear. Also, the other issue is that when you don't have a master to take readings from or don't have the mating part to check the fit with. On some long parts that have a straight section I've just adjusted table travel to the straight portion, clamped a sine bar on the table and then adjusted my angle to the sine bar to get the required angle, but sometimes even that is not possible. So I'm kind of curious on how would you measure that your taper is correct when you don't have a master for comparison or a mating part to check fit with.

A friend of mine has a CNC converted mill and a NOS retrofit spindle for a Deckel FP4 NC on it. It uses a proprietary discontinued 7/24 taper spindle and the OEM quoted him 500-900$ each for the remaining tool holders in their inventory. They went on at length to describe how "only we can machine new tool holders cause we're almighty geniuses and any peasant trying to do it themselves will blow up their shop". I came to the conclusion that you coumd rough out tool holder blanks on a CNC lathe and then chuck them up in a spindexer on a surface grinder but it seemed to sketchy to try. But now i know it will work and since the guy my friend shares his shop with has a surface grinder and a crankshaft balancer this should prove great for specialty tool holders
