- the patent EP 1 275 472 B1 discloses such a rolling tool in which balls are pressed with a liquid against a surface to be rolled. In each case, a hydrostatic bearing is provided for the balls, which is supplied with the liquid.
- a disadvantage of such rolling tools is the significant leakage and the corresponding fluid or emulsion loss.
- the invention is based on the object to provide a rolling tool whose fluid or emulsion loss is reduced.
- the rolling tool according to the invention is used for processing - in particular for smooth rolling - an inner circumferential surface of a cylindrical recess. Serves at least one rolling element, which is received in the rotatably driven rolling tool, and from this on a revolving path along the
- Inner lateral surface can be taken. It is at least one
- the fluid is an aerosol.
- the aerosol is a fluid mixed with gas and is used for hydrostatic storage and
- Lubrication Here is the amount of fluid required - according to a
- the aerosol is a mixed with air coolant.
- the air can be taken inexpensively from the environment.
- the coolant lubricates and can dissipate heat.
- the at least one rolling element is a ball.
- the circulating path on which the at least one ball moves along the inner lateral surface of the cylindrical recess is then helical. This can be rolled different lengths cylindrical recesses.
- each radial recess has a seat ring, which forms a valve for the aerosol with the ball inserted into the radial recess, wherein the valve is open when the ball on the cylindrical recess. So that's the radial
- the radial recess and the seat ring may be formed on a sleeve.
- the sleeve can be glued into the tool.
- the sleeve is inserted into the tool and from a screwed hold-down -. from a clamping claw - held in the tool. So the sleeve can be easily changed with the ball.
- the tool has a disposed on its outer periphery outwardly aerosol-supplied
- the cylindrical recess after your production or production in a first step with the tool according to the invention also cleaned (in particular freed of chips).
- a cleaning agent and in particular for rinsing the present invention in the tool available aerosol whose pressure facilitates cleaning.
- the cleaning nozzle is angled in the rotational or circumferential direction of the tool (for example by 90 degrees) and arranged on the outer circumference of the tool in front of the at least one rolling element.
- the cleaning nozzle is set against the direction of rotation of the tool. The angle of attack is e.g. 45 degrees.
- the cleaning nozzle is employed against a linear feed direction of the tool.
- the angle of attack is e.g. 45 degrees.

- the cleaning nozzle may be formed as a bore in a nozzle body which extends approximately radially from a longitudinal channel to the outer periphery of the tool.
- a arranged in the interior of the nozzle body radial channel connects the longitudinal channel with the bore.
- the nozzle body can be glued into the tool.
- the nozzle body and the rolling element or bodies can be arranged in a common cutting plane of the tool. Then there is a central point on the longitudinal channel, from which the aerosol is distributed radially in different directions.
- the tool according to the invention has a quick-release valve, via which the aerosol loading of the rolling elements or is either switched on or off, in the latter case on the
- the quick-release valve is switched via a centrifugal force-dependent circuit as a function of a rotational speed of the tool.
- the switching speed can, for. B. 3000 U / min, so that at a speed of the tool> 3000 U / min, the aerosol loading of the rolling elements and possibly the cleaning nozzle is switched on, while it is switched off at a speed ⁇ 3000 U / min.
- the shift speed may also be different when the speed is increased than when the speed is reduced (hysteresis). By the shutdown will also relaxes the aerosol loading of the rolling element or bodies and possibly the cleaning nozzle.
- the driving in and out can be done by linear movement of the cylindrical recess relative to the tool or by linear movement of the tool relative to the cylindrical recess.
- Possibility offers the advantage that further tools can be grouped together with the rolling tool according to the invention in an inverse machine, and a workpiece having the cylindrical recess of a
- Processing station can be moved to the other processing station.

- seat rings (not shown in detail in Figure 1).
- balls 10a, 10b are accommodated, there being substantially two different positions of the balls 10a, 10b: in a rest position (not shown), the balls 10a, 10b seal against the respective seat ring while they are in position in a working position over the
- Inner wall of the connecting rod 2 are lifted from the respective seat ring and pushed inwards in the direction of a longitudinal axis 14 of the tool 1. This position is shown in FIG. From inside, the sleeves 8a, 8b are acted upon by a pressurized aerosol via a longitudinal channel 12, which extends inside the tool 1 along the longitudinal axis 14.
- the aerosol is a mixture of ambient air and
- Coolants For its production, ambient air is sucked in by a compressor 16 and compressed and via an air flow meter 18 to a
- Lubricant unit 22 Coolant to the blending unit 20 promoted.
- the lubricant unit 22 has a reservoir and a pump. In the
- Blend unit 20 the aerosol is generated, which represents air permeated by cooling lubricant.
- the aerosol is a programmable Beaufscrien 24 to a
- Rotary feeder 26 promoted.
- the Beaufscrien 24 is formed by a shut-off valve and the rotary feeder 26 connects a stationary aerosol conduit 28 with a rotating aerosol conduit 30. The latter finally opens into the longitudinal channel 12, which in turn opens into the two sleeves 8a, 8b.
- FIG. 2 shows a rolling tool 101 deviating therefrom according to a second one
- Embodiment in a perspective view It's his
- Tool holder (HSK) 7 the longitudinal channel 12, the sleeves 8a, 8b and the balls 10a, 10b comparable to those of the first embodiment.
