AIGNER Single-Row Pressure Roller

Brief description

AIGNER pressure rollers are used in combination with the pressure module to ensure controlled workpiece guidance directly at the tool. Thanks to the module’s spring-loaded contact pressure, the workpiece remains in uniform contact even with dimensional tolerances and is guided stably during the feed.

Depending on the model, the range of applications can be specifically expanded: from the universal single roller for spot pressure to the four- or six-roller configurations for longer and more even guidance over greater distances. The four-roller model is also available in a safety version with a polycarbonate protective cover.

Polyamide rollers are used when workpieces need to be reliably guided during mechanical or manual feed and additionally stabilized to prevent them from lifting or tilting—for example, with curved parts, thin workpieces, or when working close to the tool.

This ensures smooth guidance and consistent contact pressure, even during demanding milling operations.

Depending on the application, the AIGNER pressure shoe or sliding shoe may be the more suitable solution.

Possible applications

• Milling tall workpieces, for example, on the RUWI milling table or a bench-top milling machine.
• Milling of round-arch friezes or curved frame profiles with uniform contact pressure and secure guidance of the tool
• Milling solid wood with varying thicknesses—the spring-loaded pressure compensates for dimensional tolerances and holds the workpiece against the stop and the table
• Routing narrow strips on a table router or the RUWI routing table with continuous contact pressure against the guide rail and table
• Machining thin plates or delicate workpieces with smooth guidance without lifting or tilting
• Milling close to the tool, in which the workpiece is additionally stabilized and guided past the milling cutter in a controlled manner
