I am refurbing my older benchtop cnc mill and it needs some parts redone. I have existing ball screws that need the ends reworked. They need to be turned down on the ends with new bearing surfaces, threads and outer shaft diameters. I also need new bearing blocks made that are of a simple design with stand offs for the motor mounts. I can supply drawings in a few days when I am free to make them. Total number of pieces turned or milled are as follows. This is a direct drive design to keep it as simple as possible. I also am not rich so full shop rates are not what I can afford. I prefer someone in the USA with a one week turnaround so I can keep moving my project forward. You can see the link to my build in this forum.
RF 31 Retrofit Re Build
For whomever gets the job and does good work at a reasonable rate I will have more custom and production work in the future. I need someone that can communicate well and does work in a timely manner.
Sample parts list:
3 ball screw ends reworked.
2 bearing blocks
8 motor standoffs
1 existing bearing block reworked larger bore
Material - 1018 CRS plate and rod. I will be black zinc electroplating in post.
