— This covers most of the parts needed to build the mill, except the stepper motors, drivers, power supply and the controller. I intentionally decided to punt on this while doing some more research. My total out of pocket cost so far is as follows: Missing cast iron parts - $226; Ball screws and axial bearings - $130; Spindle bearings - $96
— The guy from this link RF-31 Mill CNC â€" Baka Mecha looks like he used 25mm size screws and they were a little big for the amount of space in the X-axis. The nut needed to be ground off a little as shown in the picture below. ... I agree with the use of a 5/8" ball screw. Based on the loading charts that I have seen, it is plenty stiff ...

The PM-30MV CNC Mill is one of the most popular hobby mills out there. So we decided that it needed a conversion kit that would out perform the kits that are available today, By adding Double Ballnuts to our ball screws we have doubled the accuracy to the kits that are now available today. We also added
Preload the Ball Screw: Applying a slight axial force to the nut can preload the ball screw and reduce backlash. Choose Low-Lead Ball Screws: Ball screws with a low lead angle inherently have less backlash. Use Precision Ground Ball Screws: Opt for precision ground ball screws with tight tolerances to minimize backlash. 2. Wear and Tear
— My 1977 model Boston Digital CNC mill has about .0005-6" backlash due to large screws with spring loaded nuts. A friend spent a ridiculous effort and money to …
CNC ballscrew inspection, warning signs for failure and ballscrew problems to look for to help determine the need for replacement. ... Excessive servo load increase due to improper circulation of ballscrew nut balls. For preloaded ball screw nuts- remove the nut from the table or turret and turn by hand. You should feel some resistance to turn ...
— The ball screws and nuts that I got came from Roton and are rolled. This means that you may have a bit of a "drunken" thread and need to spring load any double …
This machine is based on our 18″ NexGen 5800-series mill. The 18″ mill base with ball screws comes with all-new saddles developed for the ball screws and #23 NEMA frame stepper-motor mounts with high-torque couplings. The X/Y-mill saddle has been beefed up to accommodate the larger ball screws, and it has an electroless nickel/Teflon coating.
— The choice between a rack and pinion system and a ball screw system for a CNC router depends on various factors. The specific needs of your CNC router application should be considered, balancing factors such as precision, speed, load capacity, and cost. ... Ball Screw Systems: Generally offer good load-carrying capacity. Suitable for ...

— I'm using the stock acme screw on my x3 mill for the z axis. I modified the nut to adjust backlash. I found .002" backlash was a good compromise with the added …
— Some common methods include oversizing the balls inside the nut housing; using the so-called "double-nut" or "tension nut" method; or by using a manufactured offset in the raceway spiral to change the …
— Upgrade your Bridgeport series 1 style knee mill with this precision-rolled ballscrew kit. The screw and nut assemblies are made of hardened steel for durability and long life. This ballscrew kit will provide a load life expectancy of 50 million inches of travel at an operating load of 400 pounds.
— Ensure the nut on the rail end is properly tight. Too tight and the ball screw will not move, too loose, and the ball screw will not spin when the motor spins. There is a washer behind the nut. Proper tightness is when the washer behind the nut can just barely spin freely. Adjustments should be made in ¼ turns.

— Proper ball screws have two nuts with a spring between them to take up almost all slop. My 1977 model Boston Digital CNC mill has about .0005-6" backlash due to large screws with spring loaded nuts. A friend spent a ridiculous effort and money to convert a good BP to ball screws and add CNC. He has .002" backlash.
— Combined with the hands-off nature of a CNC mill, this means hundreds of parts can be cut to close tolerances with minimal supervision of the mill. Get the Most From Your CNC Mill.
