Stepper Motors
Sherline stepper motors are NEMA 23, dual-shaft motors designed specifically for our CNC mills, lathes, and rotary tables.
Both the standard motor (P/N 67127) and the high-torque motor (P/N 67126) are rated at 2.0 A/phase and are fully compatible with Sherline CNC systems, driver boxes, and motion controllers. The dual-shaft design allows you to add handwheels for manual control when needed.       [accordion] [pane title="Features"]
• NEMA 23 frame size – fits Sherline CNC-ready mills, lathes, and rotary tables.
• Dual-shaft design – both ends of the shaft are usable; flats are ground on each end for secure attachment of handwheels and couplings.
• Standard step angle – 1.8° per step (200 steps/rev) for precise motion control.
• 2.0 A/phase – both motors are rated at 2.0 amps and work with existing Sherline CNC power supplies and driver electronics.
• 6-lead wiring – allows use in a variety of bipolar or unipolar configurations (see spec sheets for wiring diagrams).
• Designed for Sherline CNC – plug-and-play with Sherline driver boxes and motion controllers when used with the supplied connectors.

P/N 67127 – Standard Stepper Motor (with Plug)
The standard Sherline stepper motor (P/N 67127) comes pre-wired with six leads into a 5-pin DIN connector that plugs directly into Sherline’s CNC driver boxes and linear or rotary controllers. Simply plug each motor into the corresponding axis cable for a quick, clean setup. This motor is ideal for typical Sherline CNC applications where cutting loads are moderate, such as machining aluminum, brass, plastics, and light cuts in steel.
P/N 67130 – Stepper Motor (Without Plug)
P/N 67130 is the same basic motor as P/N 67127 but supplied with six raw wire leads and no connector. It is intended for non-Sherline controllers or custom installations where a different pinout or connector is required.
P/N 67126 – High-Torque Stepper Motor
Sherline’s high-torque stepper motor (P/N 67126) uses the same NEMA 23 frame size and 1/4" dual shaft as the standard motor, but delivers over 75% more holding torque. This added torque is especially useful on the Z-axis, where it can better handle the weight of the headstock and motor, and for heavier cuts or higher feed rates. Rated at 2 amps, the high-torque motor is fully compatible with all Sherline CNC machines, including complete CNC systems, the 4-axis driver box, CNC rotary tables, and Sherline linear and rotary controllers. No power supply upgrade is required. [/pane] [pane title="Specifications Comparison"]

[/pane] [pane title="Compatibility & Installation Notes"]
• Coupler requirement: Because of the increased torque, the high-torque motor (P/N 67126) must be used with the updated CNC coupling (P/N 671052). This coupling replaces the older 3-slot coupling (P/N 67105).
• Motor mounts: When used with a Sherline stepper motor mount (P/N 67101), be sure that the shaft entering the coupling has a flat aligned with the set screw. Tightening against the round shaft can damage the shaft and make removal difficult.
• Handwheel use: The dual-shaft design lets you mount a handwheel on the rear shaft for manual operation when the drivers are powered down. When the motors are energized, they hold position and cannot be moved easily by hand.
• Controller compatibility: P/N 67127 with the 5-pin DIN plug is designed to plug directly into Sherline’s 4-axis driver box, CNC systems, and linear and rotary controllers. P/N 67130 (no plug) is intended for non-Sherline or custom controllers.
Safety Note: The improper use of machine tools and accessories can result in serious injury. Always read and follow the instructions before installing or operating stepper motors, and always wear appropriate eye protection. [/pane] [pane title="Documents"]

WW Collet Sets
Collets provide a quick, easy method of mounting cylindrical parts or bar stock in the lathe with a great deal of centering accuracy. Each collet is actually a small, precision 3-jaw chuck that fits into a special tapered adapter in the headstock. A drawbar that passes through the headstock and threads into the backside of the collet is used to draw the collet up into the tapered adapter. The adapter causes the jaws of the collet to close down, gripping the part to be machined. Typically, collets provide a very accurate part mounting system, but each size collet can accommodate only a small range of diameters of approximately ±.001" (.02mm).
WW collets differ from milling collets in that they have a hole all the way through the collet and drawbar. The maximum diameter stock that can pass entirely through the collet is 3/16" or 4.5mm. The WW collets that are larger than this diameter are sometimes referred to as "pot" chucks.
The Sherline WW collet set includes a WW style collet taper adapter, a drawbar, and a set of five WW collets. These collets are manufactured by Sherline and are built to standard WW specifications; however, we have come across collets that are called WW and will not fit our drawbar and adapter. Be sure to check WW collets made by other manufacturers to be sure they fit our adapter before you purchase them. Sherline manufactures a slightly larger .315" adapter and drawbar set that will accommodate some of these other brands.
Collet Accuracy
These collets have a maximum runout of .002" or less. If the WW collet adapter is trued in as suggested in the instructions, it will run dead true. This will allow the collet runout to be at its best. Collet sizes above 3/16" (4.5mm), considered pot chucks, are not bored through. They are only bored .260" deep and depending on your setup and length of the part, you may experience greater runout further away from the front of the collet.
5-piece collet set includes:
• WW Collet Adapter*
• Drawbar & 3/8" Knockout Bar
• Set of 5 Collets: Inch set: 1/16", 1/8", 3/16", 1/4", and 5/16" Metric set: 2.0 mm, 3.0 mm, 4.0 mm, 5.0 mm, and 6.0 mm
*NOTE: Our WW collet adapter does not have a keyway pin for the collets. Our customers have been using our WW collets on our lathes without a key pin for over forty years without any problems.
Other Collet Sets
Sherline also offers sets that include a wider selection of collets. It includes 17-inch size collets from 1/16 to 5/16", while the metric set includes 14 metric collets from 1.5 mm to 8.0 mm. These sets come in an oak box with a divider that has extra holes for more collets should you add them later. It also includes a drawbar, a collet adapter, knockout bar, two collet pot chucks, and a collet blank.
The largest set we offer includes 78 collets from 0.3 mm to 8.0 mm by 0.1 mm increments. This comes in an oak box with 96 holes in case you add some inch sizes but does not include the adapter, drawbar or other accessory items in the sets described above.
