Horizontal boring mills

Measuring and optimisation of geometric accuracy of the machine

We measure geometric accuracy of horizontal boring mills manufactured by TOS VARNSDORF a.s. and RETOS VARNSDORF s.r.o. using a modern laser interferometer RENISHAW XL-80, in combination with measuring system for NC and CNC machines RENISHAW BALLBAR QC10.

Why?

  • accurate and reliable machine is one of the basic building stones of first-rate manufacture
  • poor-quality machine does not necessarily cause production of rejects – however has essential influence on labour productivity
  • there are various causes of occurrence of poor-quality products, apart from machine error – tool error, mistake on the drawing, inconvenient technology, operator's fault, error in NC programme, etc. - the wider the portfolio of potential causes is, the more difficult and longer is their analysis - it certainly is good to know that the machine is not the cause of it

Area of application:

  • Laser XL-80 - CNC and also conventional machines
  • Ballbar QC10 - CNC machines with possibility of circular interpolation

Measuring options:

  • straightness of movable groups guidance
  • evaluation of mutual perpendicularities of movable groups
  • evaluation of metering system errors and inaccuracies
  • diagnostics of clearances in movable groups drives
  • diagnostics of movable groups drives adjustment

Results of measuring:

  • expert opinion of technical condition of machine
  • summary of results in clear charts and tables
  • evaluation of results according to the ISO 230-2, VDI / DGQ 3441 and ÈSN 200300 standards

Final status - target:

  • optimisation of geometric accuracy of basic machine hardware – balance, perpendicularity, limitation of

Clearances:

  • optimisation of metering accuracy – linear and non-linear correction of metering systems
  • machine dynamics optimisation – accuracy of machining, starting up to position
  • elimination of machine hardware imperfection impact on accuracy of machining

 

The condition of measuring execution is functionality of the machine, machine readiness and measuring environment (cleanliness, stable temperature).
