The company's division Clamping Technology, with approximately 200 employees, is responsible for the product groups Tool and Workpiece Clamping. In addition to such stock items as tap holders, tapping attachments and quick-change adapters we offer a line of precision clamping tools for workpiece clamping. We are primarily a design and build supplier in this regard, so our devices are designed especially for individual customers’ applications, and are, as a consequence, highly optimized special solutions for specific production processes. In order to achieve such solutions it is strictly necessary to analyze all workpiece details inclusive of production conditions in terms of machine equipment, precision requirements, details of the production process etc., even in the first planning, or quotation stage, it's important to take every single detail into account with a close view to practical, every-day work conditions. From concept to realization, let us take you into the fascinating world of workpiece clamping.

Precision Workholding By Operation [COLLAPSE]
Owing to its high efficiency gear hobbing is the dominating chipping production process for manufacturing external geared cylindrical gear wheels. In the automotive industry as well as for big gear boxes, gear wheels are usually pre-geared by gear hobbing provided the use of the process is not limited by crash contours on the component.
Gear shaping is a process to produce gear wheels mostly used where the more economic gear hobbing is not possible. This is mainly valid for the manufacturing of internal gearing as well as external gearing with adjacent crash contours.
Soft shaving is a fine finishing procedure with geometrically defined cutting edge for gear wheels, industrially wide spread. The reason for this being wide spread is the high cost-effectiveness of this process.
Hard turning provides the opportunity to substitute expensive and complex turning processes. To make it work all parts of this system must be accordingly designed. Decisive for the hard turning result is the use of the correct machine, of the clamping device and of the correct cutting material.
To achieve today’s required accuracies of gear wheels the fine-tuned hard machining of the tooth flanks is mostly indispensable. Hob grinding is a very productive and cheap procedure for mass production of smaller and middle-sized gearíngs. For very small batch sizes (eg. big gearings) as well as for prototype production it is of advantage to use the tooth flank profile grinding providing high flexibility especially when using adjustable grinding tools.
Gear wheel honing is a cutting production process with geometrically undefined cutting edge for the final fine machining of hardened gear wheels. Besides the high efficiency honed gear wheels show a low-noise surface structure. As opposed to grinding, gear honing works with low cutting speeds (0,5 – 10 m/s) so that a thermic damage of the machined gear wheels can be excluded. Pressure residual stresses are induced into the machined tooth flanks and work out positively onto the component’s carrying capacity.
The inspection of gear wheels is very extensive and acts on the kind of gear wheel. When inspecting a gear wheel, the various parameter of gear wheels are determined by conventional length and angle measuring procedures and special gear wheel measuring processes.
