Upgrading my CNC machine |
|
I am upgrading my CNC machine to a use Ballscrew on the X axis. My old X axis used a 1/2" diameter x 10 pitch acme screw and Delrin nuts. I purchased a 900mm long x 16mm thick metric Ball screw on Ebay and am in the process of adapting it to my X axis. I had to machine new bearing blocks for the metric bearings. I also have to machine a new motor drive coupler. My old screw was 1/4" diameter where it connected to my 1/4" drive motor. I have to machine a 1/4" to 10mm adapter |

Here's the ball screw support shown mounted to the screw nut. I have to set this assembly into my machine and then drill four mounting holes. The assembly gets bolted to the lower part of my X axis/gantry |

Here's a shot of the Ball screw installed. I was able to crank up the motor speeds in Mach3 after installing this screw. It is so much faster and smoother than the old acme screw and Delrin nut. |
