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.

Pneumatic Bar Feeder Activation Cylinder Assembly
We’ve separated the Bar Feeder into two components to better support customers who want to build their own custom bar feeder system.
Beyond its use in a bar feeder setup, this assembly can also function as a programmable collet control for opening and closing the collet. You can use M10 and M11 G-code commands to close and open the chuck, respectively.
The Pneumatic Bar Feeder Activation Cylinder Assembly works with our machine and 3C lever collet closer to pneumatically open and close the collet. Click the “Instructions” tab above to download setup documentation.
NOTE: This system is designed for use with the MASSO Touch controller featuring the G3 board. The older G2 board is not compatible with the required MASSO relay module. If you are using a control system other than the MASSO Touch, please consult your controller manufacturer for wiring diagrams and compatibility. Most modern CNC controllers are designed to send relay signals to control external devices.
