Paper transport in digital printing systems is a particularly sensitive area. We rationally and reliably produce the most varied axes for the transport units. Our CNC-controlled long automatic lathes, which are deployed along with CNC-controlled lathes, produce spindles, axes and other designed components with the greatest precision.
A speciality at Hunold + Knoop is the extrusion coating of spindles, rollers and cylinders with "soft" and "hard" thermoplastics.
The high-precision components are CNC-ground and the quality is guaranteed by means of the latest laser measuring technology.
Extrusion-coated and ground to a hundredth of a millimetre 2-component pinch rolls assembled as one complete component.
Extrusion-coating with “soft”, rubber like plastics, e.g. TPU (polyurethane) or TPE (thermoplastic elastomers) and subsequent precision grinding of components.
Extrusion-coating with “hard” plastics and subsequent contour grinding on CNC machines.
