Description of the technology

Honing is a high-precision abrasive machining method in which the cutting tool, in the form of a cutting head (with the abrasive stones arranged on the circumference of the tool), carries out the primary rotary motion and rectilinear feed motions while the workpiece does not perform any working motions. The combination of these movements causes each abrasive grain of the abrasive stone to imprint itself on the workpiece along a track in the form of a helical line. When the stroke length of the head movement is in the order of tens of centimetres, the process is called long-stroke superfinishing.
