SPINDLE INSPECTOR

Rapid health check of your spindle accuracy and performance.

Spindles represent a key part of any machine tool. Not only does their performance represent a key parameter in product quality, they can represent a significant fraction of the machine cost.

The IBS Precision Engineering spindle inspector delivers a simple but highly accurate system which may be integrated seamlessly into production systems. Automated measurement at a range of user defined speeds reduces spindle performance to a set of simple parameters with definable tolerances. A ‘green light’ system allows your machines to continue performing uninterrupted until a tolerance run out is spotted; system interface options cease operation when tolerance is exceeded.  Spindle replacement can be precisely predicted; product failure and sampling reduced.

 

Key features

  • High performance non-contact measurement at 75 nm resolution
  • Measurement of dynamic spindle performance from 250 to 40,000 rpm
  • In process axis shift measurement
  • Data logging for spindle performance monitoring over time

 

Measurement takes place in a probe nest permanently positioned in the machine. The target is a high precision cylinder with a maximum roundness error of 1 μm, accommodated in the tool magazine. Three sensors in the probe nest measure simultaneously allowing a real-time dynamic radial and axial measurement. All data is acquired by an industrial real-time system and stored locally. The spindle inspector is supplied with Windows software to analyse and present the data. Multiple inspectors can be networked remotely for total factory control.
