Definitions
- the invention relates to a method for cylindrical grinding of a workpiece, in which a rotating grinding wheel is fed against a surface of the workpiece to be ground, while at the same time the workpiece rotates about its longitudinal axis, the surface to be ground being delimited by an edge and into a neighboring surface
- the invention also relates to a device for cylindrical grinding of a workpiece, with a grinding wheel and a receptacle for the workpiece to be ground
- the object of the invention is then to improve the grinding method of the type mentioned in such a way that the deburring process can be omitted.
- the object of the invention is then to provide a grinding device which makes it possible to dispense with the separate deburring process Advantages of the invention
- the method according to the invention with the features of claim 1 has the advantage that the burr which arises when the grinding wheel is brought in against the surface to be ground is automatically eliminated. A separate deburring process is therefore no longer necessary
- the deburring mandrel is printed on the neighboring surface with a force between 10 and 100 N, in particular with a force in the order of magnitude of approximately 50 N
- a pneumatic cylinder is provided, the deburring pin with an adjustable ble
- FIG. 1 is a schematic view of a grinding machine according to the invention.
- FIG. 3 shows a view of the components shown in FIG. 2 along the direction of the arrow III in FIG. 2;
- FIG. 5 shows a half section through the machined workpiece along the plane V of FIG. 3;
- FIG. 6 shows a view corresponding to that of FIG. 2, a second embodiment of the invention
- FIG. 7 is a view corresponding to that of FIG. 4, a section through the workpiece of FIG. 6;
- the grinding machine contains a frame 10, in which a receptacle 12 for a workpiece 14 to be machined is arranged.
- a drive 16 is provided with which the workpiece 14 can be set in rotation.
- a grinding wheel 18 is provided, which can be set in rotation by means of an infeed drive 20 and can also be suitably advanced against a surface of the workpiece 14 to be ground.
- the grinding machine described so far is of conventional construction, so that its construction need not be described in detail.
- the grinding machine is additionally provided with a deburring mandrel 22, which is made of hard metal and can be pressed against the workpiece 14 to be machined by a pressure mechanism 24.
- the pressure mechanism has a pneumatic cylinder 26 (see FIG. 2), the interior of which can be pressurized via two schematically illustrated pneumatic lines 28 to press the deburring mandrel 22 in the direction of arrow P of FIG. 2 against the workpiece 14.
- the operation of the deburring mandrel is as follows: If the grinding wheel 18 is advanced against a surface 30 of the workpiece 14 to be ground in the direction of the arrow Z in FIG. 2, a burr 32 is formed (see FIGS. 3 and 4) made of material exists, which is displaced onto an adjoining adjacent surface 36 via an edge 34 which delimits the surface 30 of the workpiece to be machined.
- FIG. 4 shows a section through a section of the workpiece that has just been machined by the grinding wheel 18 and now rotates towards the deburring dome 22.
- the ridge 32 is located outside the surface 30 to be machined in the area of the adjacent surface 36 adjacent to the edge 34.
- FIG. 5 shows a section through a section of the workpiece which, after contacting the end surface of the deburring mandrel 22, is again visible moved to the grinding wheel 18. It can clearly be seen that the ridge 32 has been pressed back onto the surface 30 to be machined, so that it is ground off the next time it comes into contact with the grinding wheel 18.
- the pressing force of the deburring mandrel 22 can be selected depending on the respective requirements and the material to be processed. If the workpiece 14 is, for example, a valve needle for a fuel injection valve for Verre ⁇ Vietnamesemaschi ⁇ en, in which the surface to be machined has a diameter of a few millimeters, pressure forces of 50 N are sufficient.
- the cycle described here of producing the burr by contact between the workpiece 14 and the grinding wheel 18, pressing the burr 32 back onto the surface 30 to be machined and grinding the burr is repeated until the grinding wheel fires, that is to say no material is removed and therefore no burr can arise.
- the result of the grinding process described is a workpiece 14 with a ground surface 30 that has no burr without a separate deburring process being necessary.
- the arrangement of the deburring mandrel 22 shown here relative to the grinding wheel 18 can be varied depending on the requirements. If several surfaces are ground simultaneously and in addition, for example, measuring tools monitor the grinding process, the deburring mandrel 22 can also be used in other positions relative to the grinding wheel
- FIGS. 6 to 8 show a second embodiment of the grinding machine and the grinding method carried out with it.
- the same reference numerals are used for the components already known from the first embodiment, and reference is made to the above explanations
- a cylindrical outer surface of the workpiece 14 is ground here, so that the ridge 32 is formed on an adjacent surface 36 adjacent to the surface 30 to be machined, which extends perpendicular to the longitudinal axis of the workpiece 14 the burr 32 is pressed back by the deburring mandrel 22 onto the surface 30 to be ground, as can be seen by comparing FIGS. 7 and 8
- the deburring mandrel 22 does not abut the workpiece 14 with its end face in the second embodiment, but with a conically shaped pressure face 38.
- the longitudinal axis of the deburring mandrel 22 is not aligned perpendicular to the longitudinal axis of the workpiece 14, but extends obliquely This is particularly worth mentioning that the deburring mandrel 22 is not printed against the workpiece 14 in the direction in which the ridge 32 is to be printed back onto the surface to be machined, but in a direction in which the burr was expected to continue was printed inwards towards the longitudinal axis of the workpiece.
- the ridge 32 is printed back onto the surface 30 to be ground by the obliquely positioned pressure surface 38 away from the longitudinal axis of the workpiece 1 4
- Alignment of the deburring mandrel 22 is particularly advantageous if other components of the grinding machine have to be arranged in the area relative to FIG. 6 to the left of the deburring mandrel 22, with this arrangement the pressure mechanism 24 can then be arranged far outside of this area
