I calculate the circumferance of the od of the tube minus one wall thickness for the length of weld. Most of the people I deal with use this, but not everyone.
I'd go to the library and check out a book or video on six sigma or lean manufacturing. You may be implimenting certain parts of these, but aren't using the latest buzz words.
The quality system costs us about $60k a year, in maintaining a quality person to keep the audits and us updated and the recertification process. This hasn’t stopped our customer from moving the product we make for them to “other parts of the world. The system does show you your shortcomings and...
Thanks Griffy,
This is what I was looking for. The reason I'm asking is a friend of mine works for a company that out sources all their machining. They want to bring it back into the states. I told him I'd help find companies to make the parts, but I know nothing about screw machines. "out here"...
Don't say that, my daughter's turning 17 in a few days!! Thanks for the info. I'll start searching the internet. There's a couple of used machinery dealers out here. I may go see what they have. There was a couple of machines on ebay, I couldn't tell you if they were past their prime.
Thanks guys for the information. It's what I was looking for. I'd like to find more information on setting up screw machines, I haven't started looking for any yet though.

So for cycle time do you quote only the longest running tool(multi spindle) or do you add the cycle time of each tool? Are all screw machines multi spindle? Are CNC screw machines faster to setup than manual? I want the speed of setting up a CNC machine but the economical prices of a screw...
Does anyone have information or know where to get some on estimating machined parts produced on a screw machine? I've quoted parts made on machining centers and lathes, both CNC and manual, but no experience with screw machines.
Thanks,
