JUNKER Group

With SATURN double disc surface grinding, two vertical grinding wheels grind the workpiece simultaneously at its parallel end faces. With the through-feed grinding process, the grinding wheels are positioned slightly conically to each other so that the workpiece guided through the grinding zone has not reached its final dimension until it exits.

Quality, productivity, availability – the JUMAT external and internal cylindrical grinding machine leaves nothing to be desired. Various sizes and a large number of wheelhead versions offer unrivaled versatility. Paired with the concentrated expertise of JUNKER, each machine is specially matched to the customer’s requirements.

The JUNICOR series is characterized by maximum precision and productivity. It is suitable for grinding a wide range of workpieces, from small pins to large shafts. The machines are equipped with a highly dynamic control system and a powerful grinding spindle, which ensure optimum grinding results.

The JUPITER series offers universal cylindrical grinding machines for a wide range of applications. They are characterized by their high precision, flexibility, and ease of use. These machines are suitable for both single-part production and series production.

The TAPOMAT is characterized by high flexibility, short tooling times, easy operability and a minimal contact surface. A diamond roller (single or multiple tooth) is used to profile the relevant threaded grinding wheel. Diamond fliese tools are used for profiling the chamfer grinding wheel. This allows the machine to grind any optional thread and chamfer shapes.

The QUICKPOINT grinding machines are designed for high-precision grinding of complex geometries. They are characterized by their compact design and high flexibility. The machines are ideal for small to medium batch sizes and offer a wide range of applications.

The worm shaft grinding machines are specially designed for the efficient and precise grinding of worm shafts. They offer high flexibility and can be adapted to various workpiece geometries. The machines are characterized by their robust design and long service life.

The JUCRANK series is designed for high-precision grinding of crankshafts. These machines offer maximum flexibility and productivity, making them ideal for the automotive industry. They are equipped with advanced control technology and ensure excellent grinding results.

The JUDISC series is specifically designed for grinding brake discs. These machines offer high precision and efficiency, meeting the demanding requirements of the automotive industry. They are capable of processing various types of brake discs with excellent surface quality.

The GRINDSTAR machine concept replaces turning through the use of dressing-free high-speed plunge-cut grinding. This can open up enormous potential for savings, in particular when working with large production volumes.

Up to 5.000 mm long and a weight of several tons – the KARGO series tirelessly masters grinding shafts of this size.

In the FLUTEMAT, the threaded tools are mounted with a spring-loaded square insert and tailstock center. The fixed stop at the tailstock guarantees that the start of each flute is identical. The dressing unit mounted directly behind the grinding spindle helps ensure a short cycle time. It carries out in-process dressing of the grinding wheels while the grinding or loading operation is under way.
