3.5" Chuck-Style Rotary Engraving Attachment

The 3.5" Chuck-Style Rotary Engraving Attachment, also known as the XZ-K-I, expands your laser engraving capabilities by allowing compatible cylindrical objects to rotate beneath the laser. Featuring a three-jaw chuck designed to grip the workpiece directly, this attachment is ideal for engraving bottles, cups, tumblers, and other suitable round objects.

Unlike roller-style rotary attachments that rely on surface friction to rotate an object, this chuck-style rotary holds the workpiece mechanically. This provides a practical solution for engraving items that benefit from direct gripping and controlled rotation. The attachment includes a 4-pin connector, with compatibility and any required connector changes determined by your laser machine's controller and wiring configuration.

How the 3.5" Chuck-Style Rotary Works

Rotary laser engraving allows a machine to engrave around curved surfaces by rotating the workpiece as the laser operates. Instead of moving the material across a flat engraving area, the rotary attachment turns the object in coordination with the machine's engraving movements.

The XZ-K-I uses a three-jaw chuck to grip a compatible cylindrical object. As the rotary motor turns the chuck, the secured workpiece rotates beneath the laser, allowing designs, text, and graphics to be engraved around its surface.

Direct gripping can help maintain consistent positioning, especially when working with objects that may be difficult to support on rollers. Proper chuck adjustment, workpiece alignment, and rotary settings are essential for accurate results.

Chuck-Style vs. Roller-Style Rotary Attachments

A chuck-style rotary grips an object directly using adjustable jaws, while a roller-style rotary supports an object on powered rollers that rotate it through surface friction.

The 3.5" Chuck-Style Rotary is useful when the workpiece has a suitable gripping surface and benefits from being mechanically secured. This can include bottles, cups, tumblers, and other cylindrical items that fit the chuck's gripping arrangement.

For delicate objects or items without a suitable gripping area, a roller-style rotary may be a better option. The best choice depends on the object's shape, material, dimensions, and how it can be safely held during engraving.

Additional Clearance with the Rabbit Chuck Riser Set

For projects requiring more clearance beneath the rotary, the optional Rabbit Chuck Riser Set raises the 3.5" Chuck-Style Rotary Attachment by 1.625". This provides additional space between the rotary and the laser machine's work surface.

The riser set can be useful when preparing larger-diameter items such as handled tumblers and compatible pet bowls. Raising the rotary also moves the workpiece closer to the laser head, so sufficient vertical clearance and focusing range must be available. The Rabbit Chuck Riser Set is sold separately.

Confirm Compatibility Before Ordering

Not every laser machine uses the same rotary motor connections or controller settings. Before purchasing the 3.5" Chuck-Style Rotary, confirm the following:

• Compatibility between the rotary motor and your machine's controller and motor driver
• 4-pin connector type, wiring arrangement, and electrical requirements
• Available workbed space and vertical clearance
• Chuck gripping range and suitability for the intended workpiece
• Supported rotary settings in your laser engraving software
• Ability to secure and rotate the workpiece without interference

The supplied 4-pin connector may not match every laser machine. Connector changes may be possible, but electrical compatibility must be verified before any modification. Contact Rabbit Laser USA with your machine model and rotary connection details before ordering if you are unsure.

Installation & Safety

Position the chuck-style rotary securely inside your laser machine and connect it according to the machine manufacturer's rotary setup instructions. Place the workpiece in the chuck and adjust the jaws to provide an appropriate grip without damaging the object. Verify alignment, workpiece support, and laser focus before engraving.

Disconnect machine power before making electrical connections as directed by the manufacturer. Never assume that matching connector shapes indicate matching wiring. Confirm that the workpiece rotates freely throughout a full rotation and remains clear of the laser head and surrounding machine components. Do not operate the rotary with an unsecured workpiece or incompatible electrical connection.
