Hi Guys
I need some help Guys? I am trying to decide which size of Ball Screw I should be installing in the Mill that I am converting to CNC? You can see a picture of the Mill below. The Mill will be used mainly to machine Aluminum with a little Steel. I do plan to use the Mill allot. So it’s either 5/8” or 3/4” Screws? I was originally planning to use 5/8” Screws but have been told by more than one person that I should be installing the 3/4” ones. What do you think about this?
Here is a list of the other components I will be using:
(Servo Motors)
C23-L55 Poly-Scientific.
Peak Torque = 430 oz.in.
Continuous Stall Torque = 50 oz.in.
Rated Torque = 40.5 os.in.
Rated Speed = 1700 rpms.
(Ball Screw Nuts)
Pre-loaded Ball Nuts with Wipers. (Uses two single circuit nuts per screw)
(Ball Screws)
Linear Error per foot = 0.001 to 0.003
Screw mounted on double Angular Contact Bearings
(Drives)
Belt drive with a 2:1 ratio between Servo Motor and Ball Screw.
(Mill Sliding Surfaces)
Original Cast Iron Ways.
Thanks for the help.
