RPT Models – Highest Precision

RPT800DSH

Key fea­tures of the RPT machines are the PRECITEMP® tech­nol­o­gy, which ensures ther­mal sta­bil­i­ty and thus high pre­ci­sion even when work­shop tem­per­a­tures fluc­tu­ate, and the NANOTOL® tech­nol­o­gy, which achieves sub-microme­tre pre­ci­sion in the lin­ear axes. As a result, in many appli­ca­tions, these machines often out­per­form expen­sive machines fit­ted with hydro­sta­t­ic guide­ways, such as the RHP mod­els. Com­pared with the high-pre­ci­sion RXP mod­els in prax­is, tol­er­ances and sur­face rough­ness are fre­quent­ly reduced by at least half.

The fol­low­ing machines are cur­rent­ly available:

RPT450 / RPT450DS

RPT600 / RPT600DSH

RPT800 / RPT800DSH

Dynamischer Schleifprozess – Dynamic grinding

Com­pared with the RXP machines, the motors are more pow­er­ful and, in com­bi­na­tion with a very rigid struc­ture, enable even high­er stroke fre­quen­cies for jig grind­ing. Dur­ing drilling and rough­ing, the greater pow­er offers more reserves and the dynam­ic per­for­mance is cor­re­spond­ing­ly high­er, result­ing in short­er machin­ing times.

RPT450 Innenraum – Machining area

The 5‑axis machines have out­stand­ing design features:

  • Improved tem­per­a­ture con­trol of the wear-free torque motors (direct-dri­ve tech­nol­o­gy) and the axis bear­ings to ensure ther­mal stability 
  • Strong two-sided and pre­ci­sion-opti­mised sup­port of the C‑axis for high rigid­i­ty and precision 
  • High-res­o­lu­tion opti­cal encoders in all axes 
  • Min­i­mum mass iner­tias in the mov­ing axes 
  • Spe­cial Roed­ers 5‑axis geom­e­try com­pen­sa­tion for max­i­mum accu­ra­cy, even dur­ing long machin­ing operations 
  • C‑axis swiv­el direc­tion per­pen­dic­u­lar to the X‑axis move­ment for dynam­ic decoupling 
  • Inte­gra­tion of var­i­ous chucks or tables with T‑slots possible
RPT600 Innenraum – Machining area

The machin­ing range of the 3‑axis machines is matched to the machine’s table size in such a way that the machine can mill the sur­face of the table itself to achieve per­fect flat­ness and par­al­lelism using a fine fin­ish­ing cut.

The mod­ern design of the RPT mod­els reflects the high pre­ci­sion and dynam­ics of the machine tech­nol­o­gy. Par­tic­u­lar impor­tance was devot­ed to sim­plest oper­a­tion, like unlock­ing the doors at the touch of a but­ton on the ter­mi­nal. The good acces­si­bil­i­ty of the machin­ing area from two sides, well known from Roed­ers, has been main­tained, which offers great advan­tages, espe­cial­ly for auto­mat­ed machines.

The RPT mod­els were designed for dura­bil­i­ty and ener­gy effi­cien­cy down to the last detail.
The elec­tri­cal cab­i­net usu­al­ly is inte­grat­ed into the machine. At the RPT series, the elec­tri­cal cab­i­net stands alone next to the machine so that elec­tron­ic com­po­nents are not affect­ed by vibra­tions from machin­ing or the dynam­ics of the machine. In addi­tion, the high weight of the machine and the large dis­tance between the machine feet ensure low stress despite the high dynam­ics of the axes. Numer­ous mea­sures have been under­tak­en to sig­nif­i­cant­ly reduce ener­gy con­sump­tion, e.g. a pow­er-con­trolled cool­ing unit.

RPT Edelstahlverkleidung – Stainless steel covered working area

The work­ing area of the RPT machines is ful­ly cov­ered with stain­less steel sheet met­al, ensur­ing that it retains its attrac­tive appear­ance even after pro­longed use. The steep angles of the sur­faces and feed screws in the work­ing area pre­vent the build-up of chip nests.
