Also, you may want to set the backlash comp first to zero to get the total amount of backlash to make sure it is not excessive. Reading should usually be below .008. Anything above .010 you might want to consider taking a closer look. Where is the backlash coming from? Make sure the bearings are pre-loaded properly.

A ball mill is a versatile and efficient tool for the grinding and blending of materials. Its working principle, based on impact and friction between rotating balls and the powder materials, results in the fine grinding and refinement of the material. The components of a ball mill, including the drum, grinding media, liners, and drive system ...

I have run a test piece, where I have interpolated 360 degrees to create a boss. At each 90 degree quadrant, we see the traditional 'lobe' . I believe this to be an issue not with G64 or cutters leaning over etc, but possibly backlash in the ball screw, or more likiely, backlash over compensation.

The KHK duplex worm is designed so that, for all modules, the backlash reduces by 0.02 millimeters for each 1 millimeter that the worm is shifted. As the worm wheels are produced with a backlash range of -0.045 to +0.045, a 2-millimeter axial adjustment can result in a zero-backlash pair.

Typically, backlash is adjusted by tightening the feed nut retaining screw. When I tightened the feed nut retaining screw, I was only able to reduce backlash to .030″. As the one piece feed nut wears, and backlash grows, the feed nut can either be replaced (a new one costs about $36), or split into two pieces.

It is set under the parameters, for every .500 inch of travel for each axis. I have to ask why you need to do this as I have rarely seen one that need to be set to anything other than the factory setting. If your ball screws or ball cars are worn then this would compensate.

The typical Sieg X2 mini-mill [HF 44991, Grizzly G8689, Micro-Mark & others] has a lot of backlash in the Z-axis.In my case it was .053-inches, which was almost a full turn of the fine-adjust knob. I heard that putting a shim behind the rack on the column would help by causing it to mesh tighter with the pinion gear in the head.

2) On a Fadal you would set the backlash comp afterwards by entering the measured backlash the same way: `bl,1,2,2,2` would enter 2 tenths of backlash compensation at the start, middle and end of the ballscrew. You would need to repeat this for each axis with your measured values.

Generally speaking, backlash causes even CNC machines to perform poorly and inaccurately, especially the converted ones. Besides the 'clearance' between gears, backlash can also be caused by loosening or deforming mechanical parts. Most often than not, you can reduce backlash in CNC-converted machines by replacing lead screws …
