Gear Hobbing

 

Gear Hobbing

The gear hobbing process is the dominant machining process for machining external cylindrical gears. Power transmission gears for the automotive industry as well as for high power transmissions usually are produced by hobbing unless the use of this process is restricted by the gear geometry. Therefore, the department of "Gear Manufacturing Technology" at WZL is engaged in the research of the gear hobbing process for a long time.
Within a lot of research projects, appropriate technological parameters for dry manufacturing with carbide and HSS tools have been determined. A further area of the laboratory examinations is given by the analysis of new coating systems and cutting materials. At WZL it is possible to do wear studies using an analogy trial for hobbing, the so-called fly-cutter hobbing process. This process is applied for wear analyses because of the low tool and workpiece costs and the chip forming conditions that are nearly identical to real hobbing.
