- at least one or all of the functional elements can be adjustable independently of the respective processing element, and the functional elements can in turn be combined in groups that are independently adjustable.
- At least one functional element can be adjustable independently of and / or together with at least one measuring element. If several, independently adjustable actuators are provided, these are expedient approximately coaxially one inside the other or within the hollow tool body, so that a very compact design results.

- the control line can be formed by a flexible hose or have at least one correspondingly flexible intermediate section; it is advantageously on the outside of the tool body, but can also lie within its outer surface.
- a calibration or adjustment device with at least one reference surface corresponding to the workpiece surface is also provided for a honing or measuring tool of the type described or another type, on which the respective functional element can be aligned or a reference value for its function can be derived ; E.g. guide elements can be precisely adjusted by placing them on the reference surface.

- the reference surface is conveniently located in e.g. axial path of movement of the tool that it can be started by a simple tool movement by the respective functional member.
- reference surfaces can also be provided next to one another like a magazine, for example in the manner of a rotatable revolver magazine, or can be transferred one after the other into the movement path of the tool.
- a method for measuring a workpiece surface is also proposed.
- at least one functional element is preferably re-adjusted against this surface in order to reduce its functional tolerances which have become larger as a result of the machining.
- the tool can be moved back or out of the hole in the course of the above-mentioned machining, readjusted and calibrated for a zero adjustment of the control device on the reference surface, after which the further machining is continued immediately.
- An adjustment of the respective functional element in, albeit smallest, stages can be achieved by a graduated control curve of the actuator and / or by actuating an actuator with, for example, a continuously increasing control curve via a stepper motor, the actuating steps of which can be precisely determined by a counter, so that the actual setting is precisely recorded at all times.

- a connection 30, for example a plug connection is provided on the tool 1, to which a corresponding hose or pipe of the machine can be connected.
- a coupling piece in the form of, for example, an S-shaped bent elbow is attached to the functional member 10 or the support bar 11, which projects freely to the rear adjacent to the outer circumference of the jacket 6 and by inserting it into a correspondingly enlarged end section of the channel 29 on the functional member 10 is attached.

- the tool 1 is used on a machine according to FIG. 2, on the work spindle 33 of which it is attached.
- the work spindle 33 is rotatable and axially movable with a work drive 34, an actuator 35 of this work drive 34 being designed so that the tool 1 can be converted into different axial or functional positions and can be held in the respective functional position.

- the connection 30 of the functional element 10 is via a line 45 which is led upwards along the work spindle 33 connected to a converter 46, in which the air pressure applied to the measuring nozzle 28 and more or less accumulated by the surface 44 depending on the distance is converted into an electrical value, which signals, for example via feedback control, to a control device 47 or to its measured value acquisition 48 there.
- the control device 47 also receives status signals from the working drive and / or from one or both actuating devices 37, 40 about the position and setting state of the tool 1 or the processing and functional elements 7, 10.

After this step, the tool 1 moves back into the curved surface 44 and continues the machining.
- the control device 47 can also be provided to compensate for the wear of the processing members 7. As soon as it is determined by the measured value acquisition 48 that the dimension measured by the functional elements 10 deviates from the desired target dimension by a certain amount, a signal is sent to the infeed mechanism, which allows the corresponding compensation steps to be carried out by the servomotor 41. Instead, the wear compensation can also be carried out on the basis of an empirically determined value, which results from a certain processing time and intensity.
- the machine according to the invention is also suitable for machining surfaces 44 of different nominal dimensions in succession with one and the same tool 1.
- the adjusting device 50 has a corresponding number of calibration bodies or calibration rings 51 in a magazine 53, which have reference surfaces 52 corresponding to the nominal dimensions that occur.
- the magazine can e.g. be a revolver magazine, which can be rotated about a distance axis parallel to the tool axis with a servomotor 54 so that each calibration ring 51 can be transferred into a position that is the same as the tool 1.
- the lifting drive of the work spindle 33 is designed in such a way that the tool 1 can be completely retracted relative to the latter after the calibration ring 51 has been passed through, thus releasing the magazine 53 for the aforementioned advancement.
- a magazine which could be displaced approximately linearly or at right angles to the tool axis in corresponding bearings of a machine frame could also be provided.

- a sensor 55 can be provided in the transport path of the workpieces 43 for a corresponding coding or the like on the workpieces 43, from which the nominal dimension to be machined can be seen.
- the sensor 55 transmits this information as a coded signal to the processor of the control device 47, which then makes the above-mentioned settings in the manner described and initiates the successive work steps of the adjusting device 50, which are necessary for the associated calibration ring 51 to be brought into the functional position.
- FIGS. 3 and 4 the same reference numerals as in FIG. 1 are used for corresponding parts, but with the index "a", which is why corresponding description parts also apply analogously to this exemplary embodiment.
- the different or identical designs according to FIGS. 1 and 3 can also be provided together or several times on one tool.

- the adjusting ring 38a engages over the front end of the tool body 2a, which is correspondingly reduced in diameter, and is axially secured relative to the latter, but rotatable, which can be achieved, for example, by cams projecting radially inwards, which adjustably engage in an annular groove in the tool body 2a.
- a latching device 57 is expediently provided, which can lie in the region of the rear end face of the adjusting ring 38a and an annular shoulder of the tool body 2a lying adjacent to it.
- an axially spring-loaded latching element can be arranged movably in an outer jacket part of the adjusting ring 38a, to which a ring in the ring shoulder is assigned closely spaced latching depressions, so that the adjusting ring 38a is automatically secured by a few angular degrees after each adjusting step.
- the actuator 16a is also secured against rotation and / or axially in that at least one of the passages 23a is extended to the front and a radial pin engages in the extension in the front end of the tool body 2a.
- Rotational movements of the adjusting ring 38a lead to corresponding axial adjusting movements of the adjusting element 16a and to the radial adjusting movement of the functional elements 10a.
- the tool 1a can only be operated with one adjusting device 40 for the machining elements 7a.
- the associated actuator 15a is in this case loaded in the return direction by a return spring 26a, which surrounds a shaft or the connecting member 17a releasably attached to the rear end of the control body, so that the actuating rod 39 does not form fit with the connecting member 17a or one to the rear must be coupled to this subsequent push pin.
- the actuator 16a can be produced from a section of a tube which has constant cross sections.
- the control cams 20a are then produced in the manner of ring grooves with correspondingly stepped base surfaces and sloping flanks for the sloping flank of the respectively associated control cam 22a.
