4th-Axis 4x8 Rotary CNC Router Table 1325 - Video

What This Video Demonstrates

This working video showcases a 4-axis CNC router machine in the popular 1325 format (1300 mm x 2500 mm working area) equipped with an integrated rotary table. Throughout the demonstration, the machine transitions seamlessly between flat-surface operations and cylindrical workpiece processing, highlighting the core advantage of a 4-axis system: the ability to handle both 2D sheet cutting and 3D rotary carving on a single platform without repositioning or retooling. Viewers can observe the rotary attachment gripping and spinning a wooden column while the spindle follows a programmed toolpath around its full circumference, producing detailed relief patterns that would be impossible on a standard 3-axis machine.

How the 4th Axis Rotary Attachment Works

A standard 3-axis CNC router moves its spindle along the X (left-right), Y (front-back), and Z (up-down) axes. The 4th axis adds rotational movement, typically labeled the A-axis, by mounting the workpiece between a powered headstock and a free-spinning tailstock positioned along one edge of the worktable. A stepper or servo motor in the headstock rotates the material in precise increments synchronized with the cutting head's movements, allowing the router bit to carve around the full 360-degree surface of cylindrical, conical, and multi-sided stock.

On the STM1325 platform shown in this video, the rotary unit is integrated directly into the machine bed rather than mounted as a removable accessory. This fixed-in-table design improves rigidity and reduces vibration during high-speed rotary milling, which translates into finer surface finishes and tighter dimensional accuracy on turned pieces. Operators who need a dedicated machine optimized specifically for rotary work can explore the full-specification STYLECNC 1325 CNC router with 4-axis rotary product page for detailed specs, pricing, and configuration options.

Flat and Rotary: Two Machines in One Footprint

One of the most practical benefits visible in this video is the dual-mode capability. When the rotary attachment is not in use, the full 4x8-foot table surface remains available for standard flat-stock operations such as cutting cabinet panels, engraving signage, or profiling MDF templates. When a cylindrical project comes in, the operator simply loads the round stock between the headstock and tailstock, selects the rotary program, and the machine switches modes without any mechanical conversion. This eliminates the need to invest in two separate machines and dramatically reduces the shop floor space required for mixed-production environments.

For woodworkers and small-business owners who primarily handle flat panel work but occasionally receive orders for columns, balusters, table legs, or decorative spindles, this configuration provides maximum versatility at a fraction of the cost of purchasing a dedicated 4-axis rotary CNC router machine alongside a separate flatbed unit. The 1325 bed size is particularly well-suited to this dual role because its 1300 mm width accommodates standard 4-foot sheet goods, while its 2500 mm length provides ample clearance for rotary workpieces up to approximately 2 meters in turning length.

Materials and Project Types Best Suited to This Machine

The 4-axis CNC router 1325 with rotary table is engineered to handle a wide range of materials in both flat and rotary modes. Solid hardwoods like oak, walnut, maple, and cherry are the most common rotary workpieces, producing furniture components such as carved table legs, staircase newel posts, architectural columns, and decorative spindles. Softwoods including pine and cedar are equally well-suited for production runs of porch balusters or rustic design elements where speed can be increased due to the lower material density.

Beyond wood, the machine processes medium-density fiberboard (MDF), high-density polyethylene (HDPE), acrylic, PVC foam board, and soft metals such as aluminum and brass when appropriate feeds, speeds, and tooling are used. In flat mode, these materials open up applications in sign-making, prototype fabrication, PCB routing, and decorative panel production. Shops that focus specifically on 3D multi-rotary production, such as mass-producing identical carved columns or figurines, may benefit from a 1325 3D CNC router machine with 4 rotary spindles, which multiplies output by running four identical workpieces simultaneously on independent rotary axes.

Key Features Visible in the Working Demo

Several practical details stand out in the video that are worth noting for prospective buyers. The machine uses a rack-and-pinion drive system on the X and Y axes, which provides consistent feed rates and long-term positional accuracy with minimal maintenance compared to ball-screw alternatives at this price point. The Z-axis travel is sufficient to accommodate both flat-stock operations with standard-length router bits and rotary carving with clearance above the spinning workpiece. The tool sensor shown in the video automates Z-axis zeroing between tool changes, ensuring consistent depth-of-cut accuracy without manual measurement. The DSP or NC Studio controller interface visible on screen is industry-standard software that accepts G-code files generated by popular CAM programs including ArtCAM, Aspire, Type3, and UcanCAM, making it compatible with most existing workshop design workflows.

Who Should Consider This Machine

The 4-axis CNC router 1325 with rotary table occupies a productive middle ground in the CNC market. It is powerful enough for small commercial workshops, furniture manufacturers, sign shops, and architectural millwork studios, yet accessible enough for serious hobbyists and home-based businesses that want professional-grade rotary capability without the investment required for a full 5-axis CNC router. If your production mix includes any combination of flat panel cutting, 2.5D relief carving, and cylindrical rotary milling, this single machine can handle all three without compromise.

For operators who are new to 4-axis CNC routing, the learning curve is manageable. The rotary axis is controlled through the same software interface as the three linear axes, and most CAM packages include dedicated rotary wrapping wizards that simplify the process of mapping a flat design onto a cylindrical surface. Combined with the automatic tool sensor and the sturdy steel-frame construction of the 1325 platform, this machine delivers repeatable, production-quality results from day one. Operators looking for the broadest range of 4-axis CNC router configurations can compare table sizes, spindle power, and rotary capacity options to find the exact setup that matches their production needs and budget.
