235V – Flexible shaft and center drive machines
OUR MACHINERY 235V – Flexible shaft and center drive machines

In order to give customers the highest quality, low costs per unit, and maximum adaptability all at the same time, Buderus Schleiftechnik GmbH developed the 235VH, an innovative machine platform for the high-precision machining of rotationally symmetrical axes with a diameter of up to 300 mm and a length of up to 1,000 mm.

The machines enable both combined and simultaneous machining processes. The flexible configuration options enable a wide variety of machining technologies from grinding, hard turning and honing to the use of powered tools. This means that the 235VH also facilitates the shortest set-up and processing times.

Buderus is also a specialist on the use of center drive technology. Our latest development is the 235VM center drive machine with an advanced drive head. This head achieves a working speed of up to 2,500 rpm and thus also enables the hard turning of components.

The main advantage of the center drive technology is the fact that inner and outer geometries can be machined in just one clamping, which results in greater precision as well as significantly better efficiency.

Highlights
01

The unique, sustainable machine bed made of natural granite ensures a high degree of process stability thanks to maximum rigidity, vibration damping, and optimal thermal properties.

02

Simultaneous machining with up to four cross slides in one set-up drastically reduces the set-up and cycle times with the highest shape and position tolerances.

03

Individual automation concepts offer simple, pragmatic, and even highly complex solutions.

04

The large and ergonomic 22” operation panel features outstanding haptics. and can be operated intuitively and configured individually even without additional displays.

05

The Buderus multifunctional head and the variably adjustable NS-axis, which can be swiveled up to 225°, enable the individual and flexible integration of different technologies.
