    Help from a 770 owner?

    First, I wanted to say that I’m new to the forum and so far I’ve been really impressed by all of the positive feedback/responses I’ve gotten from folks, so thanks in advance.

    I’m thinking about buying a 770 for a business. I’m evaluating the level of detail it can mill for very small pieces as well as the speed at which it mills them (this would be for a production environment). From everyone I’ve talked to, they say the 770 would be a great machine for me, but I’d still like to do a couple test runs to see what the finish quality and time is like on the machine itself before I commit to buying 1-2 machines.

    I was hoping to see if anyone with a 770 would be willing to help me do a couple test runs? There would be 1-7 small (1x1” to 2x2”) 2.5D pieces done in brass and aluminum, so I’d be looking for someone who has a fine/small set of cutters for those materials. I have the files, and I’d be more than happy to send/pay for materials as well as your time. I know this might typically go under the “RFQ” section but I’m looking to have this done specifically on a Tormach 770 to get an idea of milling time and quality.

    Anyone up for a small project?

    Thanks and appreciate the time.

    If all your doing is those two materials then yes, get a 770, but step outside that box and get a 1100, people worry about table size, but I'd trade my 1100 table for 770 spindle speed. If your part is easy I may be able to help test on both a 1100 and 770.

    It will help if you say where you are located. Ireland!!!

    Do you have the necessary gcode?

    Can you post a photo of an example of what you plan to make?

    The more info you supply the better will be the response.

    I have a 770, I would be willing to help too. Can you attach a PDF or DXF of 1 or 2 of your parts?

    Hello all,

    Thank you for the really positive responses so far. I'll PM you guys directly.

    I'm actually located in Boston (surprise), so the pieces should be fairly easy to ship.

    I attached four STL files - two models at two different sizes. Approximately. 1.5" square and 1" respectively. I also attached a couple of the DXF files and will be happy to supply the files in whatever format works best to whoever wants to help. What kind of file would work best? I don't have a CAM product yet, so I wouldn't be able to supply the GCode.
