Gehring Technologies (now Hoffmann Group) is the German engineering leader in automotive engine cylinder honing, with installations across major European, North American, and Asian engine plants. The company's distinctive contribution is laser honing technology — focused laser energy creates the cylinder cross-hatch pattern that conventional honing produces mechanically, eliminating abrasive consumables and improving process consistency. Vertical multi-spindle honing machines integrate with engine production lines at automotive cycle times. Used Gehring honing machines on Exapro come from automotive engine production environments with substantial process documentation.
