Specialist in corundum grinding
The traditional Brazilian brand ZEMA joined the JUNKER Group in 2015. Founded in 1953, the company has specialized in the production CNC grinding machines with corundum grinding wheels.
ZEMA produces ingeniously engineered machine concepts in its location in São Paulo – for grinding workpieces such as gear, turbocharger and articulated shafts, crankshaft
flanges and journals and also non-standard solutions.
ZEMA utilizes the worldwide sales and servicing network of the JUNKER Group and works predominantly for customers from the automotive and tool industry.
The corundum grinding machines fulfill the requirements of series production for a wide range of different workpieces. The CNC grinding machines grind elements such as flanges and journals on crankshafts as well as gear, turbocharger and cardan shafts with the utmost precision and reliability.
The NUMERIKA model range is designed for the series production of a wide variety of different workpieces – up to a length of 3.50 meters in the biggest model.
The cylindrical grinding machine KARGO takes ultra-heavy workpieces such as shafts for generators or electric motors with weights of up to six tons easily in its stride.
Rounding off the range are the FLEXA corundum grinding machines, which are capable of solving up to three grinding assignments with the utmost precision. Whether internal or external grinding and even thread grinding: the modular design of the robust FLEXA series makes it ideal for medium-sized production runs.
We would be happy to advise you on individual requirements such as process optimization, digital networking, and tailor-made machine concepts.
We would be pleased to invite you to our headquarters in Nordrach, where you can see the outstanding properties of JUNKER machines for yourself.
In our technology centers, you can carry out exhaustive testing using your own workpiece to assess the technical and economic performance of a machine.
