Important Update Regarding Sherline Products
October 20, 2026
We would like to share an encouraging development regarding the future of Sherline Products.
We are currently in discussions with an American manufacturer regarding the potential purchase of Sherline’s intellectual property and remaining inventory. The goal of this proposed acquisition is to preserve and revitalize the Sherline brand while providing continued availability of replacement parts, accessories, and machines for our valued customers.
As these discussions progress, we have agreed to temporarily suspend accepting new orders, effective October 19, 2026. This will allow us to preserve our remaining inventory while negotiations are underway.
Although no final agreement has been reached, we are hopeful that this opportunity will provide a positive path forward for the Sherline name and the customers who have trusted our products for more than five decades.
We sincerely appreciate your patience, understanding, and continued loyalty during this transition. We will share additional information as soon as it becomes available.
Our greatest hope is that the Sherline legacy of quality, precision, and American craftsmanship will continue for generations to come.

About the limit switches and mounts

You may connect the limit switches to Acorn or any other controller configured to work with our limit switches.

To retrofit some of our limit switch mounts, one or two holes must be drilled and tapped on your machine.

NOTE: Click the Instructions tab above for information on mounting holes and instructions on modifying your accordion way cover (leadscrew mills only).
