The Sherline Single-Axis Slide w/ Programmable CNC Controller 18-Inch is an advanced tool designed to drive the stepper motor on a single axis of a lathe or mill without the need for separate computers or drivers. This system integrates a keypad/control unit with a built-in computer chip, allowing users to operate the stepper motor directly or input simple program commands for sequenced operations. Users do not need prior knowledge of G-code to operate this device. The system allows for the input of parameters such as direction, travel distance, feed rate, and program pauses. It supports up to 40 programmed steps across two user-settable programs. Controllers can be interconnected to signal each other for sequential actions and can communicate with other CNC system controllers to execute preprogrammed functions at the appropriate times during a CNC program sequence.
The stepper motor mounts are equipped with dual ball bearings and a preload nut to eliminate endplay, ensuring precise and smooth operation. A dampened coupling connects the motor's shaft to the leadscrew, and the dual-shaft stepper motor allows for manual operation via a handwheel, providing an alternative to computer-controlled movement. The controller employs micro-stepping technology to ensure accurate and smooth travel.
Mounting options are versatile, with provisions for both bottom and top mounting. The base features four holes for bottom mounting, while angle clamps are provided for top mounting, ensuring a secure installation. The slide is available with an 18-inch table, and the package includes a linear controller with a keypad, a power supply, a #23 frame size stepper motor, a handwheel, cables, and complete instructions.
The slide has a weight capacity of approximately 10 lbs, depending on the weight's location and the table's length. For optimal performance and longevity, it is recommended to keep the dovetail and screw lubricated with light oil. Note: Do not use WD-40 as a lubricant on these slides, as it will remove the anodized coating from these parts.
