The JUNKER Group Technology Centers

Perfection in research and development

Setting new standards in grinding technology and building on our technological advantage – that is the idea behind the Technology Centers in Nordrach (Germany) and Holice (Czech Republic). The machinery in the Technology Centers, represents the entire product range and conveys the expertise and application possibilities of various grinding solutions. Intensive testing performed in the Technology Centers has resulted in groundbreaking developments and innovative machining options for new workpieces. Prospective customers can verify the technical and economic performance of JUNKER and ZEMA grinding machines using their own workpieces.

The JUNKER Group Technology Centers – At the heart of research and development

New standards and crucial momentum in research and development

The JUNKER Group Technology Centers play a key role in research and development, and are setting new standards and providing crucial momentum in grinding technology. The JUNKER Group engineers work hand in hand with the Development departments to design new solutions in intensive basic tests. This testing leads to the optimization of process flows, specialization of new workpiece applications, the identification of new materials and challenges, and the development of software and digitalization.

We aim to build on our technological advantage and develop sustainable, forward-looking solutions.

Expertise in tailoring grinding solutions to the application

The JUNKER Group Technology Centers offer unique expertise in solutions for innovative applications. Grinding solutions tailored to the application are developed from intensive dialog with customers and cover all phases of the development process. In the Technology Centers, customers have the opportunity to see innovative and sustainable grinding machines for themselves in a practical test on their own workpieces.

In this way, the heart of the research and development process provides the opportunity to directly convince customers of the technical and economic performance of JUNKER and ZEMA grinding machines, as well as the advantages and various uses of digitalization tailored to the application.

Improved performance thanks to process optimization

Integration of the latest developments enables optimized use and improves the performance of grinding machines. A targeted analysis and professional expert assessment determines the current state of a customer‘s grinding process. The optimization, redevelopment, and advancement of existing solutions plays an important role and includes assemblies and series, components, materials, production processes, technologies, software and digitalization, among other things.

The JUNKER Group Technology Centers provide momentum in improving cost-effectiveness, increasing production volumes and product quality through advanced technologies, and increasing energy efficiency and adaptation to the latest standards.

Production support services

The production support services offered by the JUNKER Group carry out tasks in the production process and link them closely with the customer‘s value chain.

The scope of services available at the JUNKER Technology Centers includes machining of prototypes in line with customer-specific requirements in order to verify the promised quality parameters and cycle times – perfect proof of a repeatable process solution.

JUMAT

The JUMAT cylindrical grinding machines handle workpieces such as shafts, injection pumps and threaded parts both internally and externally in a single clamping set-up. Diameters, shoulders, recesses, cones and bevels are machined in individual operations or as combined operations.

JUMAT

JUCAM

The OD/ID non-cylindrical grinding machines from the JUCAM series grind camshafts, cam units and individual cams of all series sizes in a single clamping set-up. The JUCAM handles various cam shapes including cylindrical/conical, concave/convex, polygonal/elliptical and shapes with a tangent.

JUSTAR

The JUSTAR grinding center is the perfect machine for the complete machining of an extensive range of workpieces, such as milling cutters, thread formers, countersinks, twist drills and taps. The cutting tool grinding machine grinds round bar stock to produce finished tools in a single clamping set-up.

JUSTAR

GRINDSTAR

The GRINDSTAR machine concept replaces turning with dressing-free, high-speed plunge grinding, which provides huge potential cost savings, especially when machining large production volumes. Typical workpieces include injection nozzles, needles, pistons, valve bodies and roller bearings.

GRINDSTAR

JUPITER

The centerless grinding machines from the JUPITER series grind roller bearing parts, shafts and engine components using centerless, through-feed, plunge and angular infeed grinding methods.

JUPITER

JUCENTRIC

The JUCENTRIC 500 centerless grinding machine is characterized by extremely short cycle times and outstanding accuracy for machining shafts and pipes. The clamping set-up between centers retains the relation to the centerline when grinding. At the same time, the work rest blade and regulating wheel guarantee perfect support.

JUCENTRIC

SATURN

The double-wheel surface grinding machines from the SATURN series feature two vertical grinding wheels for grinding workpieces such as connecting rods, rolling elements, roller bearing rings, rollers and cages simultaneously at their parallel end faces.
