Re: Ballscrew machining

Good advice but I recommend that you also not try to take an interupted cut because that will damage the carbide insert. I try to under cut the hardened area of the outer surface in one cut Dan Mauch economical 3D scanner software and kits low cost stepper and servo motors. cases for Gecko drives kits and assembled 3-4 axis drives ----- Original Message ----- From: R Rogers To: Sent: Saturday, April 12, 2008 9:49 AM Subject: Re: Ballscrew machining Most of the rolled and ground ballscrew have a 70 Rc case about 80 thou deep, lathe jaws aren't going to scratch it or deform it. Where the jaws hold it, nothing travels anyway. Strip the case with carbide tooling, then you can do all the pretty stuff with high speed steel if need be. I've never seen ballscrew that was heat-treated all the way through. It could snap and be impossible to machine if they were. The cores are a little tougher than cold roll 1018, but very manageable. For stripping the case, find a heavy lathe and some ear plugs. Ron john_glynn57 wrote: I am planning to machine the ends of a ballscrew myself in order to reduce costs. Has anyone done this? I am worried that I will damage the screw if I hold it in a standard chuck during turning and grinding. john Thank You, Ron Rogers Rogers Machine RomaxxCNC [Non-text portions of this message have been returnd] [Non-text portions of this message have been returnd] Addresses: FAQ: FILES: Post Messages: Purchase online: Purchase: List owner: Moderator: [Moderators] URL to this group: OFF Topic POSTS: General Machining If you wish to post on unlimited OT subjects goto: or go thru to reach it if you have trouble.
