Inverted Pin Routers

Introducing Onsrud’s Inverted Pin Router, a high performance solution for cutting intricate profiles. The machine’s cutter enters the workpiece from underneath, from where chips and dust are also extracted – this arrangement greatly improves operator safety and comfort. The guide pin, meanwhile, is located on top of the machine and in full view of the operator, improving the stability of both the workpiece and the cutter. This helps to ensure a smoother cutting action and allows the operator to follow complex profiles. To find out more about how it works, visit ATA online or get in touch on 01442 264411.
