A prominent cornerstone of the Okuma trade fair booth at the recent EMO 2019 exhibition was taken up by the company’s large MCR-S double-column machining centre. The machine is predestined for the die and mould industry as it combines high productivity, dimensional accuracy and high surface quality, reports Okuma.
With these properties, the MCR-S can rough, finish and fine-finish a workpiece in a single set up. The machine’s accuracy relies on a number of hardware and software technologies. One of these technologies is a swivel image sensor that measures the tool’s cutting edge. As a result, tool change related cutting edge offsets can be reduced to less than 10 µm.
According to Okuma, surface quality is achieved with the company’s intelligent ‘Hyper-Surface’ technology. By automatically detecting and correcting errors in the machining data, the application creates extremely smooth surfaces that are said to rarely need manual post-processing.
The high manufacturing quality has a positive impact on the machine’s productivity. Pablo Liechti, product manager, provides an example: “We have a customer who saved 38 hours in total when machining a large die mould with the MCR-S. They benefit from a shorter finishing cycle, fewer hours spent on polishing and little need for matching the press dies to their counterparts.”
