Hauser™ H35-Series multi-axis jig grinding machines are specially developed for applications requiring complex double curvature profiles where very high standards of surface finish and accuracy are essential. The Hauser H35 is the highest precision Jig Grinder on the market. Proven Hydrostatic slide ways allow superior accuracy and lifelong performance. This performance is coupled with the most modern control (Fanuc 300i) on the market today. The Hauser H35 has multiple spindle options to match your application. The new designed Hydrostatic guided spindle bearing system along with the extended stroke on the “U” axis (50mm) allows for excellent rigidity and stiffness resulting in accuracies within <0.5 microns.
