    Current Home Project

    Here is a project that I have been poking at for almost a couple years now. Designed with the commercial user or discriminating high end hobbyist in mind, it uses HIWIN precision ground ballscrews pushed by 1200 ozin 3 phase closed loop easy servos. .000016 step resolution and over 6K ozin torque at the gantry. Acceleration (to be tested) in the 1800-2000 ipm/sec range

    24 by 36 cutting area with a 5 or 6 tool ATC. Air operated, slide away tool rack and a few other goodies to come in the future.

    A few more shots as I wait for the spindle. I'm trying to get rid of the background clutter with a pseudo photo backdrop

    Looks like a heck of a build Gary. Hard to imagine all that power and speed in such a small package.

    I was designed with manufacturing use, where floor space is at a premium, or the discriminating high end hobbyist in mind. Over 8000 resolution at 1/4 steps and repeatable moves on the USB microscope of under 1/2 a thousandth. The extra power ensures that there is enough to push against the tight tolerance linear bearings and move at speeds you can make a dollar with.

    It certainly is a fascinating build, Gary. Can't wait to see video of it in action!

    David, et al...
    I got busy for a while and had to set this build aside. Finally got back to getting the tool rack and spindle mounted and the macros written. This video shows a test run of some of those macros. The laser pointer (XYzero), toolchanges, tool measure and dustfoot interaction with all of the above. Ive cut a few small piece, but mostly parts for the grid table system. Speeds are reduced until I have full confidence in these mostly untested macros.

    Table is aluminum with a grid of tapped holes on 3" centers. Table bolts, clamps, alignment jigs and maybe even some vacuum pucks are all intended to mount in various locations. A 3/4" MDF spoilboard with oversized holes is bolted over the aluminum.

    More to come!

    That is slicker than stewed oysters!

    That really is nice and slick, Gary! How much of the mechanism we're seeing in the video is homegrown? What about the dust shoe? I've been thinking about making one similar but if it is readily available I may just buy one.

    I guess I would have to say it's all homegrown. Of course the cylinders, fittings and numerous other products are purchased, but all other components of the machine, sans the frame, have been made in my shop on my "daily driver" a converted Bridgeport Series ll Special Edition. In the past I used my current machine to cut the parts for its successor. The mill broke that chain.

    A few shots of that machine here in the archives: http://www.sawmillcreek.org/showthre...Latest-Project

    Last look at this one before it goes to its new home. Owner requested a 6 tool changer, so this video shows those changes along with some of the other features: https://youtu.be/qtzkAExTA00

    Beautiful build, a techies dream machine.
