The bench top lathe conversion kit is similar to the bench top mini mill conversion kit.The main difference being two axis instead of three.The kit consists of 2 nema 23 stepper motor adaptors 2 ball nuts 2 ball screws all new thrust bearings, shaft connectors and all.
Most nuts are shipped with a ball retaining insert.I have purchased 2 12 ball nuts that had simple cardboard shipping tubes as retainers.As far as reloading, put as many balls in as will fit, many have more then one ball set in the same nut meaning that it is essentially 2 nuts back to back.

Sieg x2 mini mill cnc build introduction sunday, april 9, 2017 some of you might remember that several years ago i used to own a harbor freight mini mill, aka sieg x2.At one point i upgraded the xy table to the lms large table assembly and the old small table has been collecting dust under my workbench.Install ball screws on all three.
I have been working on my project for some time but have just now gotten around to write about it.My machine is the sieg super x2p hitorque mill from arceurotrade.Co.Uk the ball screws im using are from isel and the 16 mm version, this was mainly because of the very limit space under the x and y axis.My controle is the eding cnc cpu5a4 starter 4 axes in combination with a triple beast.
Considered a great tool for the price, the x2 mini mill is the kit builders top choice, and probotix offers complete conversion kits see the review to give it computer control.The platform has an active community, and the folks at cnc fusion are known for great service.
Axminster sieg super x1 micro mill ballscrew upgrade and modifications.The one thing the mill has always needed was to be made more precise for cnc milling and the original lead screws had too much play in the threads to enable us to work with small tolerances.We had planned to get ballscrews and ballnuts when we first did the cnc upgrade.

These plans provide the builder with sources for parts, detailed and assembly drawings plus full instructions for adding ball screws to your cnc converted sieg industrial x2 minimill.Ball screws add speed and near zero backlash to a mill to increase the accuracy of the parts the mill can make.
Ball screws make the machine too slippery to me for lack of a better term.There is no servo holding the screw on a manual and creeping up on a number is easier with the built in inefficiency of the acme.I did think it a great idea once, threw the ballscrews away and went back.Everyone on the floor hated it so dumpster bound.

You will have to mill approximately 0.060 1.5mm off the existing shaft key to make room for the new assembly.The shorter shaft key does not affect performance, as the bearing reduces the amount of torque required to move the axis.This mod should work with all sieg x2 derived mini mills harbor freight, grizzly, homier, etc.
A problem with the sieg x2 minimill hf 44991, grizzly g8689, micromark others is that the head can suddenly drop down while youre milling.Everything will seem fine until the head suddenly drops a bit, which causes the end mill to try to cut too much metal at once, causing the table to start shaking as much as the play in the gibs allows.
