CNC routers are incredibly versatile machines, capable of performing a wide range of tasks, from cutting and engraving to drilling and milling. However, to fully unlock the potential of a CNC router, auxiliary functions can be added. These enhancements can greatly expand the machine’s capabilities, allowing it to handle more complex projects, improve efficiency, and deliver higher precision. In this article, we’ll explore the various auxiliary functions that can be added to a CNC router, including adding a cutting saw, an oscillating knife, a drill, a horizontal spindle, and a rotary axis.

 

A cutting saw attachment transforms the CNC router into a powerful cutting machine capable of handling thicker and harder materials than those typically processed with standard router bits. This auxiliary function is particularly useful for industries dealing with wood, plastics, and composites, where precise and straight cuts are essential.

The cutting saw is mounted alongside the spindle, enabling the machine to perform cuts similar to a traditional table saw but with the added precision and automation provided by CNC control. The saw blade can be controlled to make straight cuts, beveled cuts, or even complex shapes, depending on the requirements of the project. This function works well in large panels or wood boards where high cutting accuracy and consistency are required.

Applications

Woodworking: Perfect for cutting large wooden panels, making precise straight or angled cuts.

Plastic Fabrication: Ideal for cutting thick plastic sheets with clean, sharp edges.

Composite Material Processing: Useful in industries where composite panels need to be cut with high precision.

 

The addition of an oscillating knife turns the CNC router into a machine capable of cutting flexible, non-rigid materials such as foam, rubber, leather, textiles, and soft plastics. This function is essential in industries where precision cutting of soft materials is required, such as in packaging, upholstery, or signage.

The oscillating knife operates by moving up and down at high speeds, slicing through materials with precision. Controlled by the CNC router system, the knife can cut intricate patterns and shapes with clean edges, something that would be challenging to achieve with a traditional blade. The oscillating motion allows the knife to handle materials that might otherwise tear or deform under pressure.

Applications

Packaging Industry: For cutting foam inserts, rubber seals, and other packaging materials with high accuracy.

Textile and Upholstery: Perfect for cutting patterns in fabrics and leather, ensuring clean cuts without fraying.

Signage: Useful for cutting flexible materials used in signs, such as vinyl or foam board.

 

Adding a drilling boring unit function to a CNC router allows it to perform vertical drilling operations, essential for creating holes in a variety of materials. This auxiliary function is crucial in woodworking, cabinetry, and furniture making, where precision drilling is often required alongside cutting and shaping.

The drilling boring unit is typically mounted on a separate axis or head, allowing it to drill holes perpendicular to the work surface. The CNC router control system ensures that each hole is drilled with pinpoint accuracy, which is especially important when multiple holes need to be perfectly aligned or when working with intricate designs. This function eliminates the need for manual drilling, reducing the chance of errors and increasing efficiency.

Applications

Cabinetry: For drilling holes for dowels, hinges, and handles with precision.

Furniture Manufacturing: Ideal for creating perfectly aligned holes in wooden or composite parts.

 

A horizontal spindle allows the CNC router to machine the sides of a workpiece, enabling operations such as slotting, grooving, or mortising. This auxiliary function is particularly beneficial in producing components that require complex side profiles or internal cutouts, such as in joinery or cabinetry. The horizontal spindle can be programmed to perform precise cuts and grooves, increasing the versatility of the CNC router.

Applications

Joinery: Perfect for creating mortises, slots, and grooves in wooden components for furniture or structural joints.

Cabinet Making: Useful for machining side profiles and internal cutouts in cabinet panels.

Architectural Millwork: Ideal for producing detailed side profiles in architectural components, such as moldings or frames.
