OMP has purchased a new vertical Honing machine, 7 heads; targets of this new machine are components in hydraulic sectors: valves, distributors, pump bodies.  Stability and repeatability of the process are granted, obtaining extremely tight tolerances, up to 0.6 … 0.9 microns. Dimensions and tolerances are checked in process with special gauges, air-ring-gages and Mitutoyo roundness-meter positioned in one of the two atmosphere-controlled labs. OMP is well organized to assemble, test and supply semi-finished products, i.e. hydraulic valves where the clearance piston-body is within 2…3 microns.
