The combined machining system S242 combines the technologies of cylindrical grinding and hard turning in an ideal way. Due to the design concept of the machine both applications can be done without compromises. In other words a highly productive hard fine machining of shafts and chuck components to high quality, size holding capability and fine surface finishes in one clamping. And not only interesting for large production series but also for small batch sizes and even single parts.

Vertical Turning and Grinding Center: VSC 400 DS / DDS
These turning and grinding centers combine the advantages of vertical hard turning with those of grinding. They hard pre-turn, grind internally and externally and load and unload workpiece-specific and with great flexibility.

Both these processes compete with each other. However, in several areas, the two processes also superimpose each other. For this reason, combining their strong points seems to be the most practical strategy to design the machining tasks more effectively.
Economically, grinding is the most efficient solution among fine machining processes. Hard turning - on the other hand - is preferred in cases where the quantity of removed material is higher.
The CombiGrind is a fully capable internal and external grinding machine grinder with high performance grinding units, efficient dressing technology and effective coolant and lubrication systems.
At the same time, it is also a turning machine with rigid tool holding fixtures and an appropriate working area specially designed for efficient chip removal.
Flexibility
The option of using different technologies in one machine forms the basis of an extraordinary wide range of applications spectrum. The number and positions of the workpiece can vary within a defined framework. The manufacturing process can be optimised to suit to the application by using various turning tools.
If new components are introduced to your production line CombiGrind can be re-configured for the new machining tasks. And if an increase in capacity becomes necessary, parallel machining can be implemented using individual machines. All plus points to safeguard your capital investment.

Ball Matic are machining centers to turn and grind the sphere of ball valves. Ball Matic line consists of 4 different models depending on the different maximum internal diameter of the ball (in inches): Ball Matic 24", 36", 48" and 64".
Depending on the Ball Matic model they are with a single bed (Ball Matic 24" and 36"), double bed (Ball Matic 48") or three beds (Ball Matic 64").
The turning unit consist on a Turret (Ball Matic 24") or a Blade (Ball Matic 36", 48" and 64"). The machines are also equipped with a workpiece probe to check the center of the ball. For the Ball Matic 36" and 48" model it is also available an Automatic tool changer for the turning tools.
The grinding operation is performed with grinding Cups where the Stone supports are fixed. Thanks to this unique system the best results in terms of geometry of the ball are obtained. The clamping system of the cups is of hydraulic type in order to facilitate the changing necessary machine balls with different diameters. For the Ball Matic 24" model a two position Automatic cup changer is available as option.
In the Ball Matic 36", 48" and 64" models the grinding unit is equipped with a vertical axis in to facilitate and to make possible a rapid alignment of the grinding unit with the ball center.
All the Ball Matic machines are completely enclosed with Protections equipped with sliding doors for an easy access to the machine. The high performances of these machines is also proved by the fact that they are used from the most important Ball Valves Producers all around the world.
