The Type 9129A modular three-component dynamometer from Kistler Instruments is designed for measuring machining forces up to 8kN during boring cutting and turning operations.
The dynamometer is said to be ideal for analysing process capability, investigating the machining of new materials, and optimising high-performance cutting.
The modular design allows the dynamometer to be easily adapted to match a range of lathes including VDI, Coromant and Capto plus standard turrets.
Tool holders for cutting and boring tools can be mounted on the cover plate of the dynamometer.
The piezoelectric sensor system, on which this measuring system is based, measures the forces with virtually no displacement and the design of the dynamometer is said to minimise temperature error.
Ground-loop problems are largely avoided by ground-isolated mounting of the sensors.
Provided matching cables are used, the corrosion-resistant dynamometer is protected against ingress of cutting fluids to IP67.
On twin turret, inclined bed lathes the measuring system can be mounted over or under the workpiece.
The dynamometer has been designed to ensure that the cutting edge of the tool is always at the height of the rotational axis, in the middle of the workpiece, irrespective of the mounting position.
