Instrument for measuring clamping force Testit: Hainbuch and Siemens working in partnership
Sunday, March 15, 2015Description :
Instrument for measuring the clamping force Testit, measurement of the clamping force by the machine control.

Siemens Sinumerik CNC controls are a sure value in the machine tool market and for more than 50 years, they have gained maximum productivity from each machine. And now they have a new partner: Hainbuch Testit software. Siemens [Sinumerik 840 D sl plus PCU50] is now available as an option on a data carrier. This is the end of the separate laptop but also of manufacture with "theoretical clamping forces". Thanks to Testit, the user always knows which clamping force is exer- cised and the level of maintenance of the clamping means. And with regard to the safety standard DIN EN 1550, it is a "Must have". This means: The instrument for measuring the clamping force Testit executes with the Siemens control a theoretical / real comparison of a clamping means. If the comparison is below the limit values, a warning message is issued. Perfect, is not it? With Testit, you choose the right number!

Trust is good, control is better

As soon as a machine operator or a programmer is trained, he or she is trained to behave in such a way that the parts are not likely to fly away, that is to say, they introduce a lot of safety when programming the machine. Manufacturing steps to minimize risk. Generally, however, there is no effective measurement data on the retaining forces of a clamping means and only approximate approximate values ??of the clamping force of the cylinder are available. However, if he knows the holding force of a clamping device on which the maintenance frequency depends, or also the losses in centrifugal force when turning with jaw chucks, he is very distrustful of these aid calculations and establishes High security. The machining of easily deformable parts is also very delicate. Usually, it has only a very small margin of restraint. If it is too tight, the watermark is too strongly deformed. With a lower retaining force, this is no longer sufficient to achieve rational machining by chip removal.

Safer results - even with expanding clamping mandrels

The globalization of markets, however, favors optimization of the machining process. When competition is tough, it is no longer enough to work on the "feeling". Measurement data is required! Not only does it work perfectly for external diameters and in rotation, but it also accurately measures the retaining force of expanding mandrels for inside diameters.

The most important points:

? Measurement of the clamping force for internal clamping and external clamping

? Use in rotation [with rotational speed] and stationary

? Can be used directly on the Siemens control
