The presence of any skilled operators, it consists of a number of vertical honing tools, combined with a horizontal table which index/rotates under the spindles.

Each honing tool is preset to a progressively larger diameter, and as the workpiece passes through the machine’s cycle it has its diameter increased in size by each spindle in turn. Each honing tools passes through the bore one single time only. At each pass the tool removes a specific quantity of material and the bore diameter is progressively increased, calibrated and finally finished step by step.

According to the material, the stock removal, the surfance finish and the required geometry, the honing range can include 1 to more than 10 honing tools.
