The Sherline Mill CNC Z-Axis Backlash Adjustment Upgrade w/ Oiler – Inch is designed to enhance the precision of Sherline mills by addressing the issue of excess backlash on the Z-axis. This upgrade is particularly beneficial for applications requiring subtle Z-axis movements, such as 3D modeling and engraving, where the standard backlash range of .003″ to .005″ is insufficient. The modification allows for adjustable control over the Z-axis backlash, reducing it to as little as .001″, thereby improving the accuracy and quality of the work produced.
The upgrade includes a new lock plate and a longer bolt, which are easily installed without the need for additional holes. The locking lever can be secured in various positions to control backlash effectively, using knurled thumbscrews for precise adjustments. This system is compatible with older Sherline mills, allowing them to be upgraded with the new Z-axis saddle nut featuring an oiler. The inclusion of oil reservoirs on the X/Y axes and the Z axis ensures that critical parts remain well-lubricated, benefiting both CNC and manual machines.
This enhancement not only improves the functionality of worn-out saddle nuts but also offers a more positive and easier locking mechanism for the saddle, making it a valuable addition even for machines with saddle nuts in good condition.
