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 Röders 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 tempered 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.
and the rotary axis bearings
For the first time on the 5‑axis RPT Machines, the rotary axis bearings and machine table can also be tempered. In addition, the torque motors in the rotary axes have Röders’ own greatly improved tempering. This significantly reduces dimensional deviations at higher speeds or high torque loads on the rotary axes.
of tempering circuits
- Machines completely temperature-stabilised, due to a large number of water circuits
- For highest precision the guiding rails and carriages are optionally temperature controled with a water circuit directly through the rails and carriages themselves
- Hysteresis of the cooling water for temperature control of the machine < +/-0.1 Kelvin
- Optionally for special requirements +/- 0.02 Kelvin
