Hard Finisher

 

 

Hard machining

 

Intelligent ideas

in focus

 

The Buderus Schlieftechnik and Präwema Antriebstechnik, through the collaboration within the DVS Group, have achieved yet another innovation in the area of hard machining of spure gears.

At present, hardened gears are machined in production lines by several machines thus as grinding the bore and faces and subsequent finish machining of the gear flanks.

 

The new HardFinisher® combines the complete hard machining in one machine.

 

The advantages of this complete hard finish machining process in one machine are obvious:

Ø      Shorter floor-to-floor time

Ø      Smaller floor space

Ø      Lower piece costs

Ø      Higher precision

 

 

 

 

 

 

 


 

The DVS group with their efficient engineering teams stands for quality and innovation.

 

 

 

 

 

 

 

 

 

We turn visions into reality

 

The economical production of components has been a central subject of the past decades.

 

Developments concerning various machining technologies and reduction of nonproductive times in the machining process brought the biggest progress in recent years.

 

More economic potential can be realized by combining different processes in one machine.

 

 

The complete “Hard Finish Machining has one name:  HardFinisher®

 

 

In the area of “Hard Finish Machining”, this has been achieved through the joint development between the companies Buderus Schleiftechnik and Präwema. With the HardFinisher®, the DVS Group presents a 2 spindle machine system that carries out the complete hard finish machining of spur gears.

… for this, we have brought together the brightest brains

 

 

 

 

 

 

In the first clamping, bore and faces are finish machined. Depending on the requirements, the work pieces can be machined either by hard turning or grinding.

 

 

 

 

 

 

 

 

 

 

With the loader both spindles are loaded and unloaded and the work pieces will be turned around.

 

 

 

 

 

 

 

 

 

In the second set-up the Workpiece will be finished by grinding thet gear flanks.
