The Sherline CNC Lathe Leadscrew Backlash Lock Instructions provide a solution for minimizing backlash in CNC operations, where precision is paramount. This modification allows for adjustable control over the leadscrew backlash, reducing it to as little as .001 inches. The installation process is straightforward, requiring no additional holes, and involves replacing the saddle nut securing screw with a longer one that passes through a hole in the locking plate. A pin on the locking arm fits into a hole in the locking lever, which is mounted on the leadscrew. Once the lever is adjusted to the desired position to minimize backlash, it is secured with a socket head cap screw.
This system is beneficial for both manual and CNC machines, enhancing the functionality of older lathes by upgrading their performance. Even if the saddle nut is not worn, adding this feature allows for the locking of the saddle on the leadscrew, providing control over backlash during manual operations. The locking lever and securing arm enable the leadscrew to be held in a locked, unlocked, or any intermediate position, offering flexibility in backlash management. The package includes a new lock plate that attaches to the saddle with a longer bolt, ensuring a secure fit, and a socket head cap screw for locking the lever arm in place.
