How dangerous is it to work with beryllium copper alloy C17200?
I’m a watchmaking student, i want to make my own balance wheels, beryllium copper is known to be one of the best alloys for this purpose, how dangerous would it be to work with it on a lathe? Would i have to wear a dust respirator? What about skin contact? How should it be properly handled?
Thanks for any help.
Toxicity problems with beryllium copper are mainly due to long-term dust exposure. Skin contact is no problem unless you’re allergic. Lathe work should be no problem without protective gear beyond safety glasses. I’d wear a dust mask if I was grinding/sanding on it in any quantity but watchmaking sizes of metal should be no hazard at all. The beryllium in the alloy isn’t soluble, so a cut from it is just a cut.
How to Hang the Board of Auditors on a lathe / plaster ceiling?
Old house, peeling paint, uneven roof surface, the holes. What method to sustain 4X8 sheet accounts panel. Finish nail gun does not work. out. Liquid nails is not working due to poor quality plaster. (another problem is Hubby has large metal / vehicles, but not wood, you can not afford to rent) I thought I had a quick answer to the problem of ceiling in the kitchen now have many sheets of accounts and the Board can not be installed. please help.
The thing to do is find the ceiling joists. They are the great [2x8 +] Members horizontal wood lath that his [1 x 3 / 8] is attached a. From the beams must be perpendicular to the longitudinal axis of the house and must be 24 "on center – if you is the bar, not the beam, they know that the bar always remains perpendicular to the joists. The rest is easy. Buy a sensor Magnificent. Read and understand the instructions. If esthetics allow: It's much easier to install the Board and accounts through the beams always stuck in the "valleys". I'm sure there are carpenters actual or augment or correct any of this, but this is where we must begin
Can a 4th axis CNC mill essentially do CNC lathe turning?
I'm a rookie in the world of CNC machining to forgive my ignorance, but I want to know if a 4-axis mill CMC in essence, you can equivocal operations of a CNC lathe? What puzzles me is that the "4th axis" is a head the turntable and tail stock that sits on the mill table, does this mean then that is capable of turning operations with it? I mean, apart the fact that the head of the tool of a lathe and mill end of a vertical mill to sit in different places relative to population, not the basic movement created by the rotary table identical to what a lathe with turning operations at least similar if not identical?
Yes, of course, if established to do so. I am a Machininst by trade. I know about the CNC, but have little to do with them. I am running a manual machine shop, CNC is not in it. But, you really do need the axis 4 in turn, much like you would on a lathe. Since the Z axis, which comes down in part is becoming, can be converted turn slightly in ways that turn the exterior of a piece in the same way that in turn, a piece on a lathe. The part that his return would be in a vise and mounted as any other piece, but the work could not be longer than the bit to do the job. You can also have a collar operating system installed in the bed of Horizontal mill, resting point on the other side to hold the other side of the piece in place that turn a piece incrementally, the index of it. I do not know if that would be considered the 4th axis though. Perhaps the turntable can be considered also the 4th axis. But in any case, the piece would have to spin very fast to achieve the same effect as if in a vise and rotate. internal thread can be done with a single point threading tool in a fixed part. So it is a kind of way Conversely, using a mill to do a job of threading. Only the part is stationary, but the bit is doing the work. It would be a bit cumbersome if, but, yes, can be done. Do not worry about being a newbee. I started in the mechanized world of more than 30 years. It takes years to get really good at that. Sometimes I wish never got into it, but some players have to do what some players have to do:)
I just bought a mini metal lathe (7 x 12 ") off eBay, and wondered about if something can be done in a lathe that has a high demand and could be sold. (preferably on eBay). If anyone has any idea it would be great. thanks
You will to reach a single truth Differant idea, because a manual is about the same as labor intensive and computer control (CNC) today can make a party issue seconds compared to what you can do in hours, I wish you all the luck and maybe I can come up with something. The machine that is better for some type of repair work small, where someone needs a small part at this time .. but the work is not constant ..
