Advanced Honing Technology

We are a globally operating machine tool company in the area of honing technology. Since 1926, the most important technical impetuses, which have made honing what it is today – a globally sought after high performance process, have come from us. There is hardly anyone in the entire metal working industry who wants to go without the performance we offer. This is our recognition and daily incentive.

Our pledge to our customers is optimal tribological surfaces for the highest possible efficiency. From abrasives to complete honing centers, we offer everything from one source: individual system and process solutions for individual requirements. Whether in China, Brazil, India, the USA, France, UK, or Germany, our engineers and technicians support our customers at their locations. In order to satisfy the high demands of modern manufacturing systems, we offer comprehensive training, retrofitting, and full service support via our technical service department. Over 85 years of experience and...

Honing technology – What is it? Honing is a precision stock removal process for practically all raw materials. The main application is the machining of bores, but it can also be used for plane surfaces, waves or untrue bores. The goal is improving size and shape, or rather, optimizing the tribological characteristics. This means defined surface properties which arise during friction processes, such as in bearings, engines, transmissions and machine elements. The advantage is obvious: The better these characteristics are, the higher the savings in energy cost, material use, production and...

Specifically developed technologies Position honing The future exhaust and emissions laws place considerable requirements on the oil and fuel consumption of gasoline and diesel engines. Laser honing in series production of diesel and gasoline engines has proven itself: more engine performance with less consumption, emission improvements and a markedly longer life span are possible. Instead of improving the gliding properties by means of laser honing, laser structuring can maximize the adhesion and torsional reliability. Typical application samples are camshafts and connecting rods. Part of...

Form honing Nano honing The cylindrical shape of a combustion engine distorts during operating conditions. Form honing reproduces this deformation during manufacturing which results in a nearly cylindrical shape during operating conditions. This influences exhaust quality, oil and fuel consumption, performance and wear. Form honing reacts to the current requirements of the automotive industry for higher efficiency and increased environmental consciousness. Increased component loads require a higher level of quality and the implementation of new quality parameters such as residual...
