What Is Backlash In CNC Machining and How To Avoid It?
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 CNCconverted machines by replacing lead screws with ball screws.

Eliminate Backlash From Machining Centers | Modern Machine Shop
Backlash in the X or Y axis of machining centers is most obvious when milling full circles. If any backlash exists, there will be a nasty witness mark on each quadrant line (X+, X, Y+ and/or Y side of the circle). As you probably know, backlash is caused by normal usage, and checking for backlash (easily done with a dial indicator) should be ...
How can I reduce or eliminate the backlash in a ball screw assembly?
There are several ways to reduce or eliminate the backlash in a ball screw assembly: At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios, like a 5x25mm. In some cases we can preload a ball nut in this way.

ballscrew retrofit in a bridgeport mill The Home Machinist! Chaski
Their standard ballnuts have .004 of backlash. If you ask for oversized balls the standard ballnut will have only .001 of backlash. 5/85 Ballnuts aro only about 45 each. The 6 foot length of 5/85 rolled ballscew and 3 ballnuts for my last CNC project cost about 200. Since Rockford Ballscrew is 30 miles away I pick up my orders my self.

Below, are the common parameters and program to run backlash test. Remember to Write down original values first!!! 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.

How much backlash is needed or just plain unwanted???
.005 is excellent for backlash. I was under the belief that with a DRO, backlash would become irrelevant since the DRO is measuring absolute table travel in X or Y directions. My big Webb Mill has ball screws with zero backlash in Y and .007 in X. It hasn't changed at all in the 5 years since I got the machine.

Measure and make it accurately as this is one part of controlling backlash. IIRC, I made mine out of a short piece of pipe. Also, loosen the two screws that hold the fine downfeed housing to the mill head and tap it forward to take up some of the backlash in the pinion gear for the quill. Makes all the difference in the world in backlash.
