Our partner HNC’s thermal cutting technology developed a world leading technology that extends what is achievable in roll grooving. It is now possible to specify the shape of the groove as well as its pattern profile on the roll.

Accurate advanced profiles are achieved by the use of rigid and stable cutting blades. Designed especially for the roller manufacturing industry, each blade is specifically engineered to retain its shape and offer a defined cutting edge throughout a long lasting tool life.

The ability to use bespoke thermal cutting blades in different shapes and sizes, allows unprecedented flexibility of groove shaping. Groove wall profiles, groove angles and groove radius parameters can be specified for advanced high performance rolls. Blade positioning, feed, and retraction is all handled under HNC control.

HNC Advanced HotBlade heads are integrated with the HNC control systems. Advanced and complex profiling for almost any grooved roll is possible for both rubber and polyurethane materials. HNC HotBlades are extremely durable and dust-free in operation. Heating is specifically concentrated on the cutting edge, thus ensuring minimal thermal shock or distortion of the elastomer.
