The Sherline Nickel-Teflon Coated CNC Rotary Table w/ Stepper Motor is an advanced modification of the 4-inch CNC rotary table, specifically designed to meet the demands of laser engraving applications. This model features a larger through hole, facilitating the mounting of chucks, and is enhanced with a Nickel-Teflon coating. This coating provides a rust-resistant surface that is both durable and lubricated, making it ideal for everyday production environments. The rotary table is crafted from solid bar stock steel, ensuring robustness and longevity, and weighs a total of seven pounds.

The table’s precision is underscored by laser-engraved lines every 5 degrees, with numbers marked every 15 degrees. These markings are precisely calibrated with a 72-tooth worm gear, which can be operated via a handwheel or the integrated stepper motor. The handwheel is meticulously divided into 50 parts, allowing for precise adjustments of 1/10 of a degree per line, enabling the division of a circle into 3600 increments without the need for interpolation. A full rotation of the table is achieved with 72 revolutions of the handwheel.

The rotary table’s through hole measures 15/32 inches, and it includes a chuck adapter with specific threading to ensure concentric alignment with the rotary table. The table is capable of supporting a weight capacity of 50 pounds in a horizontal orientation and 30 pounds vertically. It offers a vertical rotational torque of 6 foot-pounds and maintains mechanical backlash at 0.2 degrees or less. The table’s dimensions are 4 inches in diameter and 2 inches in height, with provisions for part mounting that include a center thread and four T-slots.

The stepper motor is a NEMA 23 frame size, delivering 120 oz-in of torque and operating at 2 amps. It provides a resolution of 28,800 steps per revolution, with a rotation speed ranging from 1 degree per second to a maximum of 50 degrees per second. The system also features programmable backlash compensation, ensuring precise and reliable operation.
