Definitions

  • the invention relates to a method for cylindrical grinding of a workpiece, in a rotating grinding wheel against a surface to be ground of Workpiece is delivered while at the same time the workpiece is around Rotates longitudinal axis, wherein the surface to be grounded bounded by an edge becomes and goes into a neighboring area.
  • the invention also relates to a Vomchtung for cylindrical grinding of a workpiece, with a grinding wheel and a receptacle for the workpiece to be ground.
  • Such methods and apparatus are known from CH 628 560 A.
  • the CH 628 560 A is a device for cylindrical grinding a workpiece with a grinding wheel and a receptacle known for the workpiece to be ground.
  • a workpiece support device makes sure that dimensional errors from the Deflection of the workpiece during processing by the Grinding wheel results when used.
  • For this purpose is a arranged opposite the grinding wheel, hydraulic pressed support jaw pressed on the workpiece, its contact pressure provided by a controllable pressure chamber.
  • the object of the invention is the grinding process of the above mentioned type to improve that the deburring omitted can.
  • the object of the invention further consists in a device for To create grinding, which allows to the separate deburring process too without.
  • the inventive method with the features of claim 1 has the advantage that when delivering the grinding wheel against the Grinding surface resulting burr is automatically removed. A separate one Deburring process is therefore no longer necessary.
  • the deburring mandrel is adjusted so that it over the neighboring surface and the Edge protrudes outward to the surface to be ground. At this Alignment of the deburring mandrel ensures that when grinding The resulting ridge again completely on the surface to be ground can be pushed back.
  • the deburring mandrel with a force between 10 and 100 N is pressed onto the neighboring surface, in particular with a force in of the order of about 50 N.
  • the forces mentioned make a good Compromise between reliable backfiring of the ridge on the one hand and there are frictional forces on the other.
  • the device according to the invention with the features of claim 6 offers essentially the same advantages as with regard to the method explained according to claim 1. Since the burr by means of the invention Grinding machine is continuously sanded again, created without a a separate processing step subsequent to the grinding process Burr-free ground workpiece.
  • the deburring mandrel with an adjustable Force can press against the workpiece to be machined. In this way can with little effort the contact force between the workpiece and The deburring mandrel can be adjusted to the respective requirements.
  • Fig. 1 is a machine according to a first embodiment of the invention shown.
  • the grinding machine includes a frame 10 in which a Receiving 12 is arranged for a workpiece to be machined 14. It is a Drive 16 is provided, with which the workpiece 14 are rotated can. Furthermore, a grinding wheel 18 is provided, which by means of a Zustellantriebes 20 can be both rotated and suitable can be delivered against a surface to be ground of the workpiece 14.
  • the grinding machine described so far is of conventional construction, so that their construction need not be described in detail.
  • the grinding machine is additionally provided with a deburring mandrel 22, the Carbide consists and by a pressure mechanism 24 against the machining workpiece 14 can be pressed.
  • the pressure mechanism has a pneumatic cylinder 26 (see FIG. 2), the interior of which two pressurized pneumatic lines 28 shown schematically can be to the deburring mandrel 22 in the direction of the arrow P of Fig. 2 to press against the workpiece 14.
  • the operation of the deburring mandrel is the following: If the grinding wheel 18 against a surface 30 to be ground of the workpiece 14 in the direction of the arrow Z of FIG. 2, a ridge 32 is formed (see FIGS and 4), which is made of material, which has an edge 34, which the machining surface 30 of the workpiece limited to a subsequent Neighboring surface 36 is displaced.
  • Fig. 4 shows a section through a portion of Workpiece that has just been processed by the grinding wheel 18 and himself now turn to the deburring mandrel 22.
  • the ridge 32 is outside of the machined surface 30 in the region of the edge 34 adjacent Neighboring surface 36.
  • the pressing force of the deburring mandrel 22 may vary depending on the respective Requirements and the material to be machined. If the workpiece 14, for example, a valve needle for a fuel Einspntzventil for internal combustion engines is where the surface to be machined has a diameter of a few millimeters, are pressing forces of 50 N sufficient.
  • the circuit described here of creating the ridge by touch between the workpiece 14 and the grinding wheel 18, the pressing back of the ridge 32 on the surface to be machined 30 and the grinding of the Grates repeats itself until the grinding wheel burns out, so no Material is removed more and therefore no burr can occur.
  • the Result of the described grinding process is a workpiece 14 with milled surface 30, which has no burr, without a separate Deburring was required.
  • the arrangement shown here of the deburring mandrel 22 relative to the grinding wheel 18th can be varied according to the requirements. If several areas be ground simultaneously and in addition, for example, measuring tools Monitor the grinding process, the deburring mandrel 22 in other Positions are used relative to the grinding wheel.
  • FIGS. 6 to 8 show a second embodiment of the grinding machine and the grinding process performed therewith.
  • the same reference numerals is used, and it is referred to the above explanations.
  • the deburring mandrel 22 is in the second embodiment not with its end face on the workpiece 14, but with a conical pressure surface 38.
  • the Longitudinal axis of the deburring mandrel 22 not perpendicular to the longitudinal axis of the workpiece 14 aligned, but extends obliquely to this.
  • the deburring mandrel 22 is not in the direction towards the workpiece 14 is pressed, in which the ridge 32 on the machined Surface should be pushed back, but in a direction in which one would expect the burr to continue towards the longitudinal axis of the workpiece inside would be pressed.
