Important Update Regarding Sherline Products
October 20, 2026
We would like to share an encouraging development regarding the future of Sherline Products.
We are currently in discussions with an American manufacturer regarding the potential purchase of Sherline’s intellectual property and remaining inventory. The goal of this proposed acquisition is to preserve and revitalize the Sherline brand while providing continued availability of replacement parts, accessories, and machines for our valued customers.
As these discussions progress, we have agreed to temporarily suspend accepting new orders, effective October 19, 2026. This will allow us to preserve our remaining inventory while negotiations are underway.
Although no final agreement has been reached, we are hopeful that this opportunity will provide a positive path forward for the Sherline name and the customers who have trusted our products for more than five decades.
We sincerely appreciate your patience, understanding, and continued loyalty during this transition. We will share additional information as soon as it becomes available.
Our greatest hope is that the Sherline legacy of quality, precision, and American craftsmanship will continue for generations to come.

Pin Jaws

Chuck not included, shown for reference only

SKU: 1140 Categories: ,

Product Description

Each year our machines and accessories are being purchased for use in fields and areas other than their intended use. One of these areas is laser engraving.

We designed our Pin Jaws specifically for laser engraving rings and other similar parts. These jaws are not designed for machining parts or other uses that require more than finger tight closing pressure to hold the part in the chuck. Round parts can be held from the inside with just finger-tight grip of the pins while the outside is laser marked. The jaws will work in any of our 3-Jaw Chucks.

We recently improved the design of the pin jaws. The hole that holds the pin now goes all the way through each jaw so you can easily knock out any broken pins.

Each Pin-Jaw Set includes:

  • 3 hardened jaws
  • 3 sets of 3 each of the following lengths of 1/8″ hardened steel dowel pins:
    • 3/4″
    • 1″
    • 1-1/4″

These pins can be changed to give you a longer gripping area.

    Rotary Table Indexer

    Sherline has advanced its precision 4" rotary table into the 21st century with the addition of Computer Numerical Control (CNC). This upgrade makes it an ideal solution for clockmakers, gear cutters, and anyone needing to machine intricate radially symmetrical patterns. The CNC rotary table takes the complexity out of repetitive indexing tasks.

    Complete, Stand-Alone System
    Programming is done entirely through the integrated numeric keypad—no computer required. The system includes everything needed for operation:

    • 4" Sherline rotary table with pre-installed stepper motor

    • Microprocessor unit with numeric keypad

    • 115 VAC power supply (universal 110–240 VAC compatible)

    • All required connecting cables

    Mounting Options
    The rotary table includes clamps and T-nuts for mounting to the T-slots of a Sherline mill table. Additional options allow for flexible positioning:

    • Right-Angle Attachment: Holds the table vertically at a 2.7" center height. A matching right-angle tailstock is also available for supporting long workpieces.

    • Tilting Angle Table: Allows mounting at any angle from 0° to 90°. At 90°, the center height remains 2.7", compatible with the right-angle tailstock.

    Simple, Accurate Operation
    Simply enter the steps per revolution (or degrees per step) via the keypad. The table advances precisely to the next position at the press of a button. If needed, previous positions can be recalled instantly.

    • Resolution: 28,800 steps per revolution

    • Accuracy: ±0.006° per step

    This precision allows for accurate machining of gears with odd numbers of teeth, and built-in calculations prevent cumulative errors.

    Flexible Integration
    This CNC rotary indexer is a complete, stand-alone unit—perfect for complex indexing operations. It can also integrate with other CNC systems:

    • Accepts input signals from an external CNC controller

    • Sends “completion” signals back to the master controller

    • Can be daisy-chained with other units for coordinated actions

    For more advanced applications, the rotary table can be linked with Sherline’s linear controller (P/N 8800), enabling seamless combinations of rotary and linear motion—ideal for gear cutting and other multi-axis operations, all without requiring advanced CNC programming knowledge.

    Weight Capacity (Continuous Use)

    • Horizontal orientation: 50 lbs

    • Vertical orientation: 30 lbs

    • Vertical rotational torque: 6 ft-lbs (e.g., able to lift a 6 lb. weight 12" from the center)

    Note: The table can handle heavier loads if not under continuous use. Refer to the Video tab for practical examples.

    Power Supply
    The controller power supply operates on 110–240 VAC and automatically adjusts for global use. (Earlier models included a 110 VAC-only power supply.)

    Compatibility with Tilting Angle Table (TAT) Limit Switches
    For instructions on using the rotary table with limit switches on the TAT, see the “Instructions” tab and download the PDF titled MASSO Rotary Table Limit Switch Interference on the Tilting Angle Table.
