PRECITEMP® — High precision also in case of temperature fluctuations in the workshop

In most appli­ca­tions, tem­per­a­ture fluc­tu­a­tions in the work­shop are the main cause of inac­cu­ra­cies dur­ing machin­ing. This also applies to air-con­di­tioned work­shops, where the tem­per­a­ture often only fluc­tu­ates by a few degrees. This has there­fore been a focus of devel­op­ment at Roed­ers in recent years. The result is the unique PRECITEMP® tech­nol­o­gy, which enables a tem­per­a­ture-resis­tant opti­miza­tion of the machine for max­i­mum pre­ci­sion with a grad­u­at­ed con­cept depend­ing on the require­ments. The machine has been viewed holis­ti­cal­ly and a com­pre­hen­sive solu­tion for tem­per­a­ture con­trol of all machine com­po­nents has been devel­oped. Min­i­mal resid­ual errors are elim­i­nat­ed with soft­ware compensation.

Heat sources in the machine such as motors, main spin­dle, lin­ear guide­ways (option­al) and rotary axis bear­ings are also tem­per­a­ture-con­trolled with high pre­ci­sion. As a result, the zero point of the machine is with­in +/- 1 µm, even with tem­per­a­ture fluc­tu­a­tions in the work­shop of up to +/- 3°C.

For the first time on the 5‑axis RPT Machines, the rotary axis bear­ings and machine table can also be tem­per­a­ture-con­trolled. In addi­tion, the torque motors in the rotary axes have Roed­ers’ own great­ly improved tem­per­a­ture con­trol. This sig­nif­i­cant­ly reduces dimen­sion­al devi­a­tions at high­er speeds or high torque loads on the rotary axes.
