NOTE: The photo shows the stepper motor attached to a crosslide, but this kit adapts it to drive the saddle leadscrew. A replacement leadscrew and collar are included which are not shown in the photo.
This stand-alone controller is programmable from its own keypad and controls the function of the stepper motor to which it is attached. The stepper motor may be mounted to drive the leadscrew of a Sherline lathe. (A separate kit is available for the crosslide as P/N 8850.) A stepper motor mount, dampened coupling, preload nut, drill guide block, new 15" leadscrew, collar and complete installation and use instructions are included.
Using a power feed offers several advantages: 1) A constant feed rate gives a smoother, more consistant final finish, 2) The chance of errors due to miscounting handwheel revolutions is reduced and 3) No physical effort is needed for long cuts or returning the saddle to its starting position after a cut is complete. Programming is quick and simple, and programs are repeated at the touch of a button with a high degree of accuracy.
The linear motion controller has its own keypad and built-in computer. It comes with its own power supply, a #23 frame size stepper motor, connecting cable and complete instructions. An 8-pin mini-DIN cable can be used to connect multiple units in a "daisy chain". The units can signal each other to work in sequence, allowing multiple movements to be accomplished without the use of a computer or master CNC controller. They can also be used in conjunction with existing CNC controllers. The controller is user-programmable with two separate programs of up to 40 operations (blocks) each. In each block you can control distance, direction, speed and whether the program pauses or proceeds to the next block.
The linear controller can also be "daisy chained" with Sherline's rotary controller (P/N 8700) or other linear controllers to achieve combinations of rotary and linear movement in sequence. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads.
