Which applications suit this machine?

A typical application for the combined turning and grinding technology on the VLC 350 GT is the hard machining of chucked components, gear wheels of various designs, sprockets, pump rings and bearings. It offers high flexibility, productivity and quality – especially when machining pump rings. Pump rings play an important role in the manufacture of pumps, as they contribute significantly to the precision and efficiency of hydraulic systems. One specific application example is the radial piston pump, which is widely used for pumping lubricants in systems, machines and automatic transmissions.

Where do you see the greatest advantages of combination technology?

The technology combination of turning and grinding on the VLC GT offers several advantages. By combining several processes on one machine, such as hard turning and grinding, considerable rationalization potential can be tapped. The advantages of complete-machining, quality and flexibility gains speak in favor of the process combination. The technology has proven itself in practice and is used very effectively to reduce cycle times. If the complete hard finishing process is carried out on one machine, lead times as well as transport and idle times can be drastically reduced. There are also advantages in the reduction of set-up processes and set-up times.

What makes the VLC 350 GT unique in terms of its technological diversity?

The unique technological diversity of the VLC 350 GT lies in its ability to integrate a wide range of machining technologies such as hard and soft turning, out-of-round grinding, drilling, reaming, milling and honing. This diversity enables the efficient machining of a wide range of workpieces of different sizes and complexity.
