This series of horizontal honing machines are specially designed for the processing of small and medium-sized small hole parts: the machine tool feed system and size control system are purely mechanical structures, and the small and medium-sized workpieces are stable and reliable, with high precision, capable of grinding, high precision and convenient operation.

The progressive honing sequence is very simple and does not require 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.
