Richard Furrer Posted December 10, 2012 Share Posted December 10, 2012 Hello All, Anyone know a fab shop who wants to shear some specific sizes from sheet for me? I have spoken to five shops in my area and been turned away by four and waiting a week for a quote from another. I'm not opposed to laser cutting, but feel this is a job for an automated shear. I may end up buying a small shear (minimum 1/8" x 24" capacity) for this gig and slowly doing it myself, but I'd rather locate a cnc shearing shop. I need 20,000 small pieces cut from sheet. Target size is mostly 0.25"x 6" from under 60 thou material...need them flat... not made into curls by a poorly tuned shear or throat-less Beverly type hand shear. Please don't bother telling me to buy slit strip from a supplier...the job is shearing these from small sheet not sourcing new raw material. It is a peculiar specialty job and it requires shearing. If I can not find a shop then I am open to a shear if anyone knows/has one for sale. Ric Quote Link to comment Share on other sites More sharing options...
JNewman Posted December 10, 2012 Share Posted December 10, 2012 Waterjet may be better to keep them flat. They could stack them to speed up the cutting time. Quote Link to comment Share on other sites More sharing options...
clinton Posted December 10, 2012 Share Posted December 10, 2012 Stacking them would increase the cutting time it may speed up handling time. Waterjet machines move faster for thinner material or material that is easier to cut (You should see one cut Styrofoam) Quote Link to comment Share on other sites More sharing options...
Richard Furrer Posted December 10, 2012 Author Share Posted December 10, 2012 waterjet company claims that the thin material (14,18,20 and 60 thou) will float under pressure of the jet...so no go. Ric Quote Link to comment Share on other sites More sharing options...
Judson Yaggy Posted December 12, 2012 Share Posted December 12, 2012 Ric, what exactly are your dimensional tolerances and repeatability tolerance? BTW, I once saw this show on making a Viking sword and I think that 20,000 layers is a few too many ;) Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted December 12, 2012 Share Posted December 12, 2012 Might be lots of shops in the Chicago area Ric. I don't know them. If I was buying I would get a new (sharp) tool for that job. Here is one that looks pretty good and reasonable: http://www.northerntool.com/shop/tools/product_120048_120048 You might be surprised at how quickly you can make headway with one of these foot stompers... I have cut a lot of metal on them. You need at least 16 gauge capacity... so most of the little bench toppers won't do that... they'd wear you out anyway. I'd probably figure one of these machines into the bid and then keep it after! A quick calculation and I get about 8 to 10 hours to do this with one of these machines. It would take more time to setup the machine than to complete the job... even packaging and time spent discussing it with the customer would dwarf the production time!
