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.
