- the carriage 8 moves to the workpiece and presses the contact control 10 against the target pressure load the workpiece.
- a vibration drive or actuator drives (not shown) the contact roller 3 in its axial direction oscillating.
- the tape is replaced by an overlay of Feed movement and the oscillating motion at the Surface of the workpiece moves and with the target pressure load against pressed the workpiece, creating an excellent Surface quality is achieved.
- the warms up Workpiece surface only small, so that soft skin formation, Residual stresses, microstructural changes and cracks are avoided.
- the particular advantage of the invention is that for the operation the surface processing device 1 only electrical Energy but no further or additional drive energy like e.g. Compressed air is required.
- the target pressure load between the surface processing tool and the workpiece can be constantly kept constant because it is electronically controlled.
- Conventional pneumatic controls have relatively large pressure fluctuations, which can lead to an uneven compressive load and thus uneven surface quality.
- the invention can be modified or developed as follows.
- a current measuring device is provided, the electrical drive 11 supplied electrical Amperage measures and a signal corresponding to the measured Amperage of the control device supplies.
- the control device determines a pressure load from the measured current between the surface treatment tool and the workpiece.
- the control device on a table, a Characteristic, Drucklasteichung or another figure reference take, or it can take the pressure load from a mathematical Calculate formula. Based on the specific pressure load electric drive controls the control device the electric drive 11 such that the target pressure load established.
- the electric drive 11 supplied Power or current based on the measured Amperage be regulated. This will put the pressure load between the machining tool and workpiece more precisely on the Set pressure load set.
- the control device determines from the target pressure load a power to be supplied to the electric drive 11.
- the Target pressure load can be via an input device in the Control electronics are entered.
- the control electronics determined on the basis of the entered nominal pressure load, the electric drive 11 power to be supplied from a table, Characteristic curve, pressure load calibration or from another illustration.
- a pressure load measuring device for measuring the Pressure load between the machining tool and the workpiece intended.
- the pressure load measuring device sends a signal according to the measured pressure load to the control device. This allows the control device to the electric drive 11 supplied electric power or current on the Regulate the basis of the measured pressure load, reducing the pressure load between the tape and the editing tool even more detail the target pressure load is regulated.
- the pressure load measuring device can be arbitrary in the power flow be arranged, that is, they can, for example, directly to the Pressing part 3, the pressure roller 10, the feed unit 12 or be the electric drive 11, since, for example, the pressure force in the power flow between electric drive 11 and the workpiece is substantially the same.
- the feed unit 12 of the electric Drive 11 a threaded spindle. This can be done simultaneously big stroke and a reasonable pressure to be generated.
- the invention is not limited to that of electric drive is a spindle motor or the like. It It is also conceivable that the electric drive is a linear motor or a piezo actuator. In the case of a piezo actuator controls the control device applied to the piezoelectric actuator electrical voltage instead of electric current, such as this e.g. in an electric motor is the case.
- control device can the take-up 5, the the tape is wrapped around the take - up reel 4, so that the Feeding the tape has a constant speed.
- This is advantageously a uniform Surface finish achieved.
