Today I launched Fine Line Automation, a site that sales affordable CNC Parts. I have partnered with Ahren Johnson of CNCRouterParts.com. My product lines are extensions of his. For now, I am offering machined steel rails to use with Ahren's linear motion carriages.
These rails are designed to be very cost competitive. $200 for a machine with a 3'x3'x6" cutting area. I challenge you to find a better price. These rails are 1018 cold rolled steel flat stock with CNC cut mounting holes for 5/16" bolts.
In addition, I am an official distributor for CNCRouterParts.com and carry all of there components. Please check out my offerings and ask any questions you might have.
