Several models of small lathes and mills are available, ready for your stepper motor and CNC controls
Sherline Products offers a 3.5" lathe in two bed lengths as well as two versions of a small 3-axis mill plus a deluxe 8-direction mill. Each of these machines can be ordered with stepper motor mounts in place of the standard handwheels. If dual shaft stepper motors are used, Sherline's standard handwheel can be used on the second motor shaft to drive the stepper motor manually if desired. Handwheels are included for each axis. (Note: The stepper motor should be unplugged from the CNC system when used manually. Rotating a stepper motor by hand can cause it to act as a generator, sending current through the system and possibly damaging electronic circuits.) Sherline also offers a high quality, dual shaft stepper motor with over 100 oz-in. of torque as an option.
FEATURES:
The lathes and mills feature dovetailed machine slides with tapered gibs, a 90-volt DC motor with electronic speed control offering continuous control over spindle speed from 70 to 2800 RPM. The spindle will accept any of the large line of chucks and collets made by Sherline. The machines are finished to high quality standards and, though small, are serious machines when it comes to producing accurate, small parts. All the capabilities of full size shop lathes have been scaled down to a size where they can be easily operated on a benchtop or table while sitting down. The design incorporates the use of a number of well-engineered extrusions to produce a machine that is light in weight and portable yet is rigid enough to handle tough machining tasks. The working components are all metal, with plastics used only sparingly and where appropriate. The machines are completely machined and assembled in our own plant in Vista, California. Complete details on the machine tool line can be found by visiting Sherline's tools and accessories page at www.sherline.com.
The stepper motor mounts supplied with these lathes and mills are the same mounts used on the industrial slides. They feature a dampened coupling and are sized to take a stepper motor with a 23 frame size.
Single-Axis Controllers Available
Sherline also offers single-axis controllers to drive the stepper motor on any individual axis of the lathe or mill. No separate computer or drivers are needed. The keypad/control unit has its own computer chip built in. It is all ready for you to use the keypad to drive the stepper motor directly or to enter simple program commands to do sequenced operations. Parameters that can be entered are direction, distance to travel, feed rate and whether or not the program pauses to wait for another command or proceeds to the next step. Up to 40 programmed steps of four parameters each can be entered into either of two separate user-settable programs. Controllers can be interconnected with a cable to signal each other to act in sequence. They can also be connected to other CNC system controllers to communicate with "sense" and "acknowledge" signals so that they perform their preprogrammed functions at the proper time during a CNC program sequence.
Complete Systems with Computer AND Software also Available
See www.sherline.com or the CNC slides page in this site for details on Sherline's complete CNC mill, lathe or CNC shop package systems. They include CNC ready machines as described below, stepper motors and the computer, software and drivers to run them. These are perfect for many small CNC operations for the home shop or small manufacturing jobs. They utilize the highly stable, Linux operating system and EMC (Enhanced Machine Contoller) software developed by the National Institute of Science and Technology (NIST) which runs industry standard G- and M-codes. Because Linux operates in real time, no buffering is required to make up for multi-tasking pauses that occur in Windows systems. This is a great way to get into CNC or to run small jobs on an inexpensive machine to free up bigger machines for more demanding tasks.
