Translation of "Zerspanleistung" in English

The machining takes a relatively long time since the cutting efficiency is low.

The tools are extremely rigid, provide high transmissible torques and offer high cutting efficiency.

Optimized technology ensures maximum cutting performance.

The JUSTAR machining center from JUNKER features a high-performance grinding spindle for high cutting capacity.

Basically they serve their purpose in a satisfactory manner and as a rule have a sufficient machining efficiency.

The drive, i.e. the main spindle, is where process integrity coupled with a high chip capacity continues.

Here, a high material removal rate can be achieved in a secured process with as low a workpiece rotational speed as possible.

This has the advantage that the metal cutting power does not fluctuate much across the width of the grinding wheel.

Due to the support of the crankshaft 1 with the center drive support 17, a rattling of the crankshaft during machining is reliably prevented so that a high machining precision and a high cutting capacity is achieved.

A good and reliable support of the workpiece is possible, since the workpiece remains stationary during the machining, so that a high cutting efficiency, a high machining accuracy, and low costs, are assured.

In spite of considerable improvements made within recent years, grinding belts still have the drawback that their machining output decreases with increasing use and the resulting roughness height of the belt decreases considerably.

The cutting capacity of the miller depends on the quality of its cutting edge and inserts are already known which are provided with a particular cutting layer or cutting-material layer forming the cutting edge.

Furthermore, it is known that due to better cooling of the grinding wheel and of the workpiece, due to shorter contact times of the abrasive grain with the surface of the workpiece, and of course, due to greater cutting depths, the cutting performance of grinding wheels can be improved.

Due to the wear of the edge a contour can be produced in the wheel peripheral surface which is not the optimum with regard to metal cutting power and service life.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to create an indexable insert which meets the highest demands regarding the tool life and surface quality, as well as machining efficiency.

Their additional lubricating layer provides increased stock removal rates and significantly reduced temperature in the grinding zone, which prevents workpiece structural changes.

It must be possible to optimally machine high stock removal, large bore diameters and varying structures while taking into account the tolerance parameters, the stability of the part and the performance of the machine.

The fully-automatic changer for 30grinding wheels, the high-performance grinding spindle with high cutting capacity, and the automatic coolant nozzle tracking ensure that mid-size quantities also leave the machine with the same level of workpiece quality.

In the prototype or small-batch production of gear wheels, the grinding worm is used for what is called roughing, which provides for a high removal rate and hence a shorter machining time.

CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life.

The high-performance grinding spindle for high cutting capacity, the automatic coolant nozzle tracking and the clever measurement system with automatic dimensional correction are also important for unmanned production.

We can proudly report that the chipping capacity has now been increased to more than 26 t bd/h.

With respect to other single-indexing processes, the completing process is characterized by a higher productivity (double chipping capacity); however a change of the flank shape is more difficult because changes in the kinematics of the machine will always have an influence on both flanks, just as with all processes comprising a two-flank-cut.
