Thermal cutters available on the market today can create 3D shapes from materials such as Styrofoam, Styrodur, polyurethane foam and others. However, when used to cut curved shapes at a given radius, the cutting element leaves visible marks in the material. The perfect solution of this problem is Coner RotoCut compass cutter.

RotoCut compass cutter is a device specially designed for architectural industry. It is an ideal complement to typical thermal cutters available on the market. The compass cutter uses a resistance wire, heated to 800°C (1472 F), to cut curved elements in materials of up to 130 kg/m3 density. The digitally controlled motion of the heated wire causes the surrounding material to vaporize, producing a precise and even cut.

Any shape you can imagine. The forming wire (1.5 mm diameter) is capable of producing an incredible variety of shapes. Shapes created with this method can have any kind of notches, curves, angles, or even cavities. Shaping can be applied to nearly 360 degrees of the outer surface of elements.

The ability to create element of any curvature with high precision and without any visible transition marks is unique among thermal plotters available today. Using RotoCut the cutting process runs at a high speed, and can be applied to nearly 360 degrees of the element's surface.
The cutter works at a linear speed of 1000 mm per minute. This ensures high quality and precision of curved shapes.
