CNC honing machine for flat-topped honing of cylinder blocks of internal combustion engines.

HONMASTER HM20 CNC honing machine is designed for flat-topped honing of cylinder blocks of internal combustion engines. This is an analogue of Rottler (USA) and Sunnen (Switzerland) machines. The machine table moves along the X and Y axes. This frees the operator from having to rearrange the cylinder block during the honing process.
The Z-axis drive is equipped with a servo drive. This allows you to achieve high accuracy of movement and avoid collision of the hon head with the cylinder block at the bottom point. This is especially true for Subaru engines. The decompression (radial feed) of the bars is carried out automatically, during the honing process. The operator does not need to manually unclench the bars. The amount of expansion of the bars is programmed through the CNC system. Due to this, there is no need to "catch" the dimensions of the cylinders. The system of automatic correction of the cylinder shape allows you to automatically carry out nursing, in order to obtain the required cylinder geometry.

The cone of decompression (radial feed) of the hon head has the opposite direction, which solves the problem of cone formation in the lower part of the cylinder. The load control system allows you to implement the principles of flat-topped honing. Thanks to the adjustment of the required load and processing parameters, it is possible to control the surface relief, change the ratio of the area of pits to the area of a flat surface. Coolant system with automatic activation.
The ACNC v1.4 CNC system of its own design allows you to flexibly manage the technological process and adapt to customer requirements.
