Framo Morat GmbH, a specialist in gear wheel and drive technology based in Baden Württemberg, is relying on grinding technology from Junker.

“We’ve been working with high-precision technology from Junker for a decade now,” confirms Alexander Denz, head of industrial engineering at Framo Morat. “As part of our growth strategy, we continue to develop our core skills – for cylindrical grinding operations we are much better positioned in terms of quality and process reliability. The two ‘Lean Selection’ high-speed grinding machines from Junker play a significant role in this.”
Junker’s two cylindrical grinding machines have proven their high speed in single or multiple-shift operations. Framo Morat wanted an economical and, above all, flexible machine concept which could fulfil all grinding assignments – from one-off production to the manufacture of small or large volumes. The machines are equipped with CBN grinding wheels and operate at peripheral speeds of up to 140 m/s. Some of the benefits of these machines include longer tool service life and extended dressing intervals.
“We grind diameters from 8 to 80 mm for shaft components with teeth, and component lengths of 40 to 460 mm,” says Denz. “Our production batch sizes range from 200 to 2000 workpieces per year. The new machines give us more flexibility with the peel grinding process, as opposed to grinding with corundum, as there is no need to change the grinding wheel between different workpieces.”
Notably, the high-speed grinding machines also deliver better quality by producing the entire outside contour in a single clamping set-up. The integrated measurement devices in the collar and longitudinal position are key control and monitoring systems during grinding.

Advanced Grinding Solutions (AGS) had no less than 10 of its machine manufacturing partners exhibiting at the recent EMO 2019 exhibition in Hanover: Rollomatic (tool grinders); Bahmuller and Tschudin (internal/external and centreless grinders); HandlingTech (automatic loading systems); Gerber and Magnetfinish (deburring machines); FLP (lapping and fine-grinding machines); Nova (external/internal grinders); Platit (coating machines); and Comat (filtration systems).

Rollomatic showed many tool grinders, including its six-axis 830XW for manufacturing large diameter cutting tools that has a novel combination of hydrostatic guides and linear motors for high levels of surface finish. Also of major interest was the Rollomatic LaserSmart 501 machine for machining PCD, CVD, and natural diamond tools. The 501’s machining speed is stated as being up to four times faster for processing multiple features such as cutting edges, chip breakers, and cylindrical lands in one operation. The machine has four cameras for complete and easy viewing of all laser operations. Rollomatic also used the show to debut its NP50 machine for the grinding of cutting-tool blanks.
Tschudin was exhibiting its latest ‘Cube’ grinder, which is stated as being the world’s smallest CNC centreless grinding machine, while HandlingTech displayed various loaders for machines, including its advanced palletZ and ecoZ models.
Platit exhibited its most flexible coating machine, the Pi 411 Plus, while Gerber focused on three brushing machines for deburring components, including the new Eco-Innovation, which received its worldwide debut.

DMG Mori has been honoured with this year’s innovation award from the German Association for Supply Chain Management, Procurement and Logistics (Bundesverband Materialwirtschaft, Einkauf und Logistik – BME).

The award was presented to the company for its successful purchasing and logistics management in front of some 2000 guests in Berlin. DMG Mori’s award-winning concept impressed the judges with its automated order transactions, global matrix organisation with regional purchasing units, and integrated IT solutions. The entire value chain is now networked.

A second-hand 1000-tonne forging press from Schuler has been installed at Schondelmaier GmbH. The press, which had been providing dependable service at a major automotive manufacturer since 1985 still had “plenty of life left in it”.

Over the course of just a few weeks, the machine was dismantled, transported to Schondelmaier’s headquarters in Germany’s Black Forest region, re-assembled and commissioned into service.
“We believe that this press will run for another 20 years,” states managing director Joachim Schondelmaier. “Used presses from Schuler are basically always a safe bet. We purchased a pre-owned 500-tonne hydraulic machine through Schuler subsidiary Vögtle earlier this year, while our press shop also houses a number of other cold-forging machines from Schuler.”

The new MikroTurnGrind 1000 from Hembrug Machine Tools combines the advantages of precision hard turning and fine grinding in one machine. Kyal Machine Tools is the UK agent.

By combining both techniques, hardened workpieces can now be machined complete in one set-up, which saves on process steps and costs. Moreover, sub-micron precision can be achieved by, for example, avoiding clamping errors.
In addition, the absence of re-clamping errors results in sub-micron accuracy. The machine has a B-axis that offers optional space for features such as an external grinding spindle with a 300 mm diameter grinding disc and an internal grinding spindle.
If preferred, one of the grinding spindles can be replaced with a milling spindle. The MikroTurnGrind 1000 has a maximum machining capacity of 380 mm diameter.
Hembrug’s MikroTurnGrind 1000, which has fully hydrostatic bearings, can produce workpieces up to a diameter of 380 mm, or 200 mm x 1000 mm between centres. According to Hembrug, the machine is ideally suited to small to medium-sized product series. Automation is optionally available. The MikroTurnGrind 1000 was presented in public for the first time at the recent AMB 2019 exhibition in Stuttgart.
