I'm using a micro-mill, the table is around 200x90 (mm) with three grooves. I'm currently using a small claming kit. I'm drilling/countersinking/counterboring into small rings, generally 65mm in diameter (max) and down to 42mm minimum diameter. These are generally 4-8 holes, which need to be countersunk or counterbored. The rings are only 1-3.5 mm max in depth, usually, and they're almost always aluminium. In order to get things lined up correctly, it can take quite a while. I have to adjust the clamps and move things around each time usually. If I have projects where I need to do over ten of these (as well as lots of other related work) it's just very time consuming, and I generally end up breaking it up (time wise) when I believe it could all be done in one go with the correct mounting. I've thought about a rotary table & chuck, however, I do not believe I would be able to grip the rings well enough without warping them. What do you think? I thought about a larger table, without a chuck, and just using clamps, but I just don't think that is possible. Is there another solution that I've not thought of? Thanks for any advise :) |

sounds like a rotary table with a chuck (soft jaws bored to the size you need) and a "bung" to go in the centre would work. the bung will allow you to hold the ring firm without squashing it, its what we do all the time at work! |

Hi Jim, Thanks for your thoughts! Do you have any photos of this so I have a better idea of how I'd set it up myself? |

how about some pics of what it is your drilling ect would be nice so to see exactly what your trying to do. please :thumbup: |

Okay, I will try, but I'm not working on anything right now so don't have anything to hand. It's pretty simple though, just a ring as described that needs to be clamped and unclamped all the time to move to the next drilling point. I will see what I can find tomorrow as an example :) |
