MCR-S possesses a cast-iron double-column structure that is equipped with Okuma’s ‘Thermo-Friendly’ concept. As a result, any unnecessary heating-up can be prevented, while thermal deformations are compensated. When manufacturing press dies, this factor is especially important because the machining process can often take days or even weeks, making it vulnerable to changes in temperature.
By using a swivel image sensor that rotates relative to the indexing angle of the tool, accurate measurements of cutting-edge position can be provided, improving accuracy even further. The sensor also helps to ensure traceability by recording the captured images.
Okuma’s ‘Hyper-Surface’ premium solution eliminates the need for hand finishing by creating die surfaces that are ready for use. Hyper-Surface improves surface quality by automatically detecting disturbances in the CAM-output machining data and correcting them on the CNC while maintaining the required shape accuracy. In this way, Hyper-Surface also increases throughput since raw material is processed in shorter timeframes.
The MCR-S machine possesses a heavy-duty cutting capacity, reaching a chip removal rate of 710 cm3/min when face milling. Average continuous feed rates of 20 m/min for the X and Y axis, and 10 m/min for the Z axis, contribute to the machine’s productivity. In addition, the ServoNavi application autonomously maximises table acceleration according to component weight.
For process-intensive manufacturing, the machining centre is equipped with a laser that allows for additive manufacturing via laser metal deposition (LMD). This way, subtractive and additive manufacturing methods are combined in one machine, enabling manufactures to not only produce complex parts, but to repair defective workpieces. The laser can also be used for surface treatments, such as laser hardening.
