Precision Workholding

This system is a reliable mechanical solution for those tight tolerance accurate workpieces where runout in the 2µ range is required.

This system is for those larger tolerance clamping diameters and loading clearances.

This system is not only accurate, but it utilizes / clamps as much of the workpiece surface area as possible, which ultimately affords more accuracy in terms of tolerance average, and transferable torque values.

This is our hydraulic line which is used when loading clearances and workpiece tolerances are tight, and or, when thin workpiece materials may deform under the workholding pressure.

This system is generally used for precision pitch line clamping of a gear in the pitch diameter, and is often used for machining surfaces which carry a tolerance; geometric or standard, back to the pitch line of the gear.

We have several different offerings for quick change systems which can be adapted to your machine and operation being performed. Perfect for short run part families.

Although our offering of design and build precision workholding can on some level be considered a special application just by the definition of design and build. There are some workpiece geometries, operations environments which may require one or more of our systems to be utilized in order to accomplish the customers process goals. So when we design something like this we consider it a Special Application.

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.
