Clamping Force Gauge Testit, Clamping Force Measurement over Machine Control
The clamping force measuring device increases productivity through precise clamping force measurements.
The Siemens Sinumerik CNC controllers have been getting the maximum productivity out of each machine for over 50 years. Now they have another partner on their side: the Hainbuch Testit software. It is available on a data carrier for installation on Siemens CNC controllers [Sinumerik 840 D sl plus PCU50. This means that a separate laptop is not needed anymore and manufacturing with »theoretical clamping forces« is also a thing of the past. Thanks to Testit, the operator always knows which clamping forces exist and where, and the actual maintenance status of the clamping device. And given the safety standard DIN EN 1550, it is a »must have«. This means: The Testit clamping force gauge together with the Siemens CNC controller executes a target-actual comparison of the maintenance status of a clamping device. If the limit values are underranged, a warning message is output. Perfect, don´t you think?
Trust is good, control is better
Based on his apprenticeship a machine operator or programmer has been taught to work in such a manner that a workpiece does not get destructed, e.g. when programming the manufacturing steps he builds in a lot of safety measures to minimize this risk. However, in reality, effective measurement data regarding the holding forces of a clamping device, and also in regards to the clamping forces of the clamping cylinder itself can only be obtained as vague reference values. A machine operator who knows how dependent the holding forces of a clamping device derive from its current maintenance status are, or from the centrifugal force losses while turning with jaw chucks, is extremely sceptical of such makeshift calculations and hence builds in a high safety value. Machining of easily deformable components is also extremely critical. Usually only a very small margin of holding force is available. If an item is clamped too strongly, a sensitive component will be excessively deformed. Applying to little clamping force results in an inefficient set-up for rational machining.
Safe results - even with mandrels
However, the globalization of markets requires an optimum of the machining process. Those who face stiff competition can no longer afford to manufacture just by »feeling«. Measurement data is demanded! It not only functions perfectly for outer diameters and during rotation, it also precisely measures the holding force of mandrels for inner diameters.
Key advantages:
• Clamping force measurement for O.D. and I.D. clamping
• Can be used rotating [under RPM and for stationary applications
•Â Direct input onto the Siemens CNC controller
