The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Improve the motion and accuracy of your mini-mill in your X/Y travel with the ACME leadscrew and "anti-backlash" acetal/delrin leadnuts. *Ballscrew kits and plans are coming soon too*
Use axial ball bearings, instead of plain old radials. Set up to zero backlash, or a light preload. Use a castle nut & cotter pin, or even a nylok or stover nut. If there is adequate threads on the spindle, you could double nut it. Two jam nuts may fit, and would be adequate.
Backlash Calculation. 1. Move an axis in one direction farther than the maximum possible backlash. (Example .020, hopefully less than that is needed!) 2. Mount a dial indicator and zero it. 3. Move the axis again in the same direction for a specific distance (it doesn't matter how far). 4.

mill and two 24' x 39.5' ball mills will be briefly discussed. All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors. Copper Mountain has installed on all three mills, the new state-of-the art dual pinion mill drives. All the inherent operation and maintenance features of this
The sides have a 2.2° draft angle, so a ball mill seems necessary to avoid a stepped finish. But now that I understand (I think) why the carbide bit exploded, maybe I should get a 4mm 2-flute flat endmill to rough, and use a 4mm ball mill to finish, so I don't have those pockets. With that I might even be able to rescue this part.
A properly aligned Ball Screw will exhibit consistent servo loads throughout its travel. If the servo load is not consistent, the following procedure should be used to align the Ball Screw: Break loose then lightly snug the following Bolts: Nut Housing to axis in question Bolts (Saddle, Table, Spindle Head, Etc.) Ballscrew to Nut Housing Bolts

Rockford Ball Screw manufactures preloaded ball screw kits for Bridgeport standard Series 1 mills and Knee Mill clones. Bridgeport Retrofit Kits Offer Many Convenient Features: High-Capacity, Long-Life: Each ball nut assembly of the Rockford preloaded unit has one circuit of 3 1/2 turns of ball bearings.
Ball Mill Sole Plate. This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate. After all shimming is completed, the sole plate and bases should be grouted in position.
I was thinking of the backlash issue too, b/c I have ballscrews on a new CNC mill in the basement and it's soooo much nicer than trapezoid screws for the purpose: lots of back-and-forth motion.

Meek Mill is facing social media backlash after he branded the flight attendant of a private jet racist after he and his entourage were asked if they were smoking weed as they boarded a flight.
The present invention is directed toward a material handling, processing and milling facility which utilizes ball milling as a means for material grinding, mixing or mechanical alloying of materials. The system includes an automatic ball charging, agitating and indexing assembly, constructed and arranged to deagglomerate and directly distribute a plurality of grinding balls to the facility.
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.

Backlash- If positive backlash it could be ballscrew end float, worn drive nut,or guide way play. If negative backlash the machine parameter might be overcompensated. If unequal backlash then there could be a wind up in the ballscrew where it becomes stiff on one end of the travel.
