If the advance per revolution of the second grinding disk 35 during plunge grinding according to FIG.

With plunge-cut grinding, the grinding wheels are arranged exactly parallel to each other.

Centerless grinding machines may be used for plunge grinding or for through-feed grinding, for instance.

Grinding machines of that kind may be generally used for plunge grinding and/or for through-feed grinding.

For plunge grinding, inclination angle a typically has a value of about 0.5°.

With SATURN plunge-cut grinding, the grinding wheels are arranged exactly parallel to each other.

There are two principles for less grinding: feed-through grinding and plunge-cut grinding.

The centerless plunge-cut grinding method entails grinding workpieces with offset or profiled diameters.

In plunge-cut grinding and swing-frame grinding, in-process-measuring and process-control devices for controlling grinding processes are known.

However, it is also possible for the interior wall of the longitudinal bore to be ground using infeed grinding.

In a development of the aforesaid exemplary embodiment, the cam is once again rotated after plunge grinding, and ground with the second grinding disk along a second contour located inside the first contour.

In a rapid traverse, the cam 41 is now rotated so that in the same way, the other zone 55b is ground away by plunge grinding, again with the cam 41 stationary.

In a preferred embodiment of the process in accordance with the invention, after grinding with the first grinding disk the cam is brought to a stop and the zone is essentially ground away with the second grinding disk by plunge grinding.

The wavy profile according to the invention can be produced very precisely in diameter by means of plunge-cut grinding, wherein at the same time, the surface of the pump piston also becomes very smooth.

The grinding wheel can have a particular contour at the perimeter in order to produce a corresponding, opposing contour on the workpiece by perforation grinding.

The technologies applied: centerless grinding (through-feed and in-feed), numerical and between-centre grinding, flat lapping (Lapmaster), flat surface grinding, paired parts.

The CBN wheels can be used for infeed grinding, multiple plunge-cuts and longitudinal grinding as well as for the machining of various shoulders and radii.

Thus the extreme loading for a grinding wheel on the outer edges and lateral flanks, such as occurs in the case of plunge grinding, is eliminated.

This rough grinding was performed by plunge grinding, so that both flat shoulders which enclose the respective journal between them are ground simultaneously.

Since in plunge grinding the grinding wheel determines a mirror-symmetrical shape of the workpieces to be ground round, it may be provided that the grinding wheel also be dressed before grinding, preferably using the height-adjustable dressing device, also at the places where the workpieces bear on the grinding wheel depending on their height offset during grinding.

Further, also when plunge grinding an at least minimum inclination by inclining the regulator spindle about the X-axis may be desired so as to (axially) receive the workpiece in a defined fashion.

In the case of plunge grinding, the axes of rotation of the grinding wheel and the regulating wheel are aligned almost parallel with each other, but at a slight angle of about 0.5° relative to each other to induce a forward thrust, pressing the workpiece against a limit stop which is precisely defined in the axial direction relative to the grinding device and thus retaining it firmly in its axial position.

However, it often happens that the roundnesses and precision quality in workpieces that have been ground simultaneously after undergoing plunge grinding with one grinding cycle in a multiple production process are variable in most cases.

Accordingly, the object of the present invention is to obtain more consistent quality in terms of uniform quality and optimum roundness of workpieces that are ground simultaneously in one cycle of a plunge grinding process.

However, during plunge-grinding it is precisely this area of transition of the radius to the lateral surfaces that must have the greatest grinding performance on the planar shoulders of the bearing surface.

For instance during plunge-grinding, if after repeated grinding of bearing bushes the grinding surfaces 6 C and 6 D have experienced wear that is outside of the grinding tolerance, the width of the grinding tool can be reset by resetting the setscrew 23 by a specific scale value on the scale 11 .
