RHP Machine Models

RHP Machines

The RHP machines differ from the RXP machines in terms of the guideway concept. Hydro­static guideways in all axes improve the running perfor­mance significantly:

  • Micro-movements across the travelling direction of the axes in the sub-micro­metre range, as encoun­tered with roller guideways, are reliably prevented.
  • The controlled hydro­static oil film between the moving slide and the guideways provides additional damping.
  • The precise tempe­rature control of the hydro­static oil is effective directly at the guideways, prevents tempe­rature fluctua­tions and hence thermally caused defor­mation of the machine geometry.
  • Because the axis covers and weight compen­sation for the Z axis (patented) are optimised for minimum friction, the axes exhibit an ideal drive control response.

The funda­mental technology of the RHP machines corre-sponds to that of the RXP series: linear motors in all axes, Röders RMS6 control, exact tempe­rature stabi­li­sation, compen­sation of the spindle elongation etc.

  • Hydro­static axis construction with hydro­static guideways preten­sioned by the magnetic field of the linear motor
  • High-precision glass scales with a position resolution of 1 nanometre
  • Wear- and friction-free

Less micro-movements across the travel direction and therefore a much smoother running of the axis slide with hydro­static guideways in compa­rison to guideways with roller or ball bearings

The manifold options for the RXP series are also available for the RHP machines, e.g. rotary swivel units for 5‑axis machining etc. The RHP machines are excel­lently suited to the combi­nation of HSC milling and grinding.
