The product portfolio is typical for the region because it has its origins in the watch industry: Gear wheels, planetary gears and worm gears through to complete geared motors.

"Our group of companies has grown by 44 percent in terms of turnover over the past six years. One of the biggest drivers of this positive development is the electric two-wheeler sector. But we have also been involved in the e-car sector for ten years," reports Alexander Denz, Head of Industrial Engineering at Framo Morat. The company is also firmly established in medical and rehabilitation equipment technology, storage and conveyor technology as well as in the field of renewable energies and automation technology.

The growth of the drive specialist has now also resulted in an intensification of the business relationship between Framo Morat and the Junker Group: "We have been working with Junker's high-precision technology for a decade. As part of our growth strategy, we are continuously developing our core competencies - in the area of cylindrical grinding, we have positioned ourselves much better in terms of quality and with greater process reliability. Two Lean Selection speed grinding machines from Junker now make a significant contribution to this," says Alexander Denz.

The two cylindrical grinding machines prove themselves as high-speed grinding machines in single or multi-shift operation. The customer wanted an economical and, above all, flexible machine concept that could handle any grinding task - whether single part production, small or large series production. The grinding machines are equipped with CBN grinding wheels and can operate at peripheral speeds of up to 140 m/s. Longer tool life and dressing intervals are just two of the resulting positive effects.

More flexibility in the sanding processes

As different types of workpieces for very different industries have to be produced on the Lean Selection speed, the new technology from Junker creates the desired flexibility: "We grind the diameters of the shaft components here with gearing from 8 to 80 mm and a component length of 40 to 460 mm. Our production batch sizes range from 200 to 2,000 workpieces per year. The new machines give us more flexibility in the peel grinding process compared to the grinding process with corundum, because we no longer have to change grinding wheels between the different workpieces," explains Alexander Denz. The high-speed grinding machines ensure better quality, as the entire outer contour is processed in one clamping operation. The integrated measuring devices at the collar and longitudinal position are important control and monitoring systems during the grinding process. By using the lean selection speed grinding machines, it is possible to process workpieces flexibly using the plunge-cut method in addition to the peel grinding method.

Framo Morat is part of the change in the supplier industry

Anyone who can hold their own in the face of technological change naturally also attaches importance to becoming even more future-proof with an investment such as the two lean selection speed grinding machines. Denz explains: "Thanks to this investment, we are now also producing parts that we didn't have in our portfolio before," and continues: "Previously, we didn't achieve the desired quality with regard to the gear widths on the oil pump gears. We had a lot of rejects that had to be sorted out by hand. Now, thanks to Lean Selection speed, we can offer our customers higher qualities."
