The RK (former URM-K) measuring instrument is a flexible device to inspect profiled shafts and wheels. Probing is carried out via two large balls and is based on double flank contact. The traditional place for the URM-K is on the shop floor directly next to the production machine. This location is ideal for quick and reliable sampling inspections.

Features and Applications:

• Quick determination of gear features such as dimension, concentricity, pitch and tooth curve. Approx. 1 minute per gear profile
• Diameter inspection for size, concentricity and roundness
• Calculation of axial references on diameters and gearing to determine the positional deviations
• Measuring constant velocity joints
• Highest precision through substitution methods (calibration on a setting master) and available axis compensation.
• Measuring balls from dia. 1 to dia. 25 mm and measuring pins
• Automatic 6-fold measuring ball change
• Temperature compensation available for device and workpiece
• Easy to use, manual or fully automatic
• Very little set-up requirement
• Very robust design, to be used on the shop floor directly next to the machine tool
• Link between production and inspection room
• Simple and freely programmable system
• Documentation of the measuring results for process control with various interfaces: QS-Stat ®, Transferformat, csv® format, pdf® format etc.
• Customer specific adaptations of mechanics and software.
• Interlinked usage within automation for 100% inspections is possible.

Types:
The RK is available with different options. Horizontal instruments are ideal for the inspection of shafts up to a length of 800 mm. Instruments with a vertical spindle are ideal for the inspection of wheels and joints up to a dia. of 300 mm. We are happy to advise you on and supply you with tailor-made instruments for your requirements.
