  • The Mini-Mill Head Drop Problem – MachinistBlog.com

    A problem with the Sieg X2 mini-mill [HF 44991, Grizzly G8689, Micro-Mark & others] is that the head can suddenly drop down while you're 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. When you finally hit the power switch and ...

    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.
