Definitions

  • the invention relates to a method according to the preamble of claim 1 and an arrangement according to the preamble of claim 4.
  • the profile shape of the workpieces and the necessary grinding wheel circumference have their course in the axial direction of the grinding wheel or the workpiece.
  • the profiles of the grinding wheel and workpiece point in their respective circumferential directions no deviations from a circular profile shape, but the profile dimensions in the respective sections of such workpieces or grinding wheels can have different diameters.
  • grinding wheels which have axially parallel grooves with a depth of 1 to max. wear about 1,000 ⁇ m. These grooves serve to be able to use different roughness depths, for example for rough grinding or fine grinding. For this they are at angular intervals of max. 1 ° arranged. These are micro-grooves that form narrow webs or groove edges lying side by side between them, which are effectively comparable to cutting edges.
  • a dressing roller is used, with which a fixed speed ratio which is dependent on the one hand on the number of grooves to be produced on the grinding wheel and on the other hand on the number of cutting edges of the dressing roller is maintained. For this purpose, such a dressing roller is positively coupled to the grinding wheel by a mechanical gear.
  • Arrangements for grinding profiles, in which support for the generation of the corresponding profiles, for example polygon profiles, is dispensed with are more advantageous.
  • a non-round workpiece, a non-round grinding wheel and a non-round dressing roller are coupled to one another by a kinematic transmission with which the speeds are to be coordinated with one another.
  • Alone in coordinating the rotation of the workpiece and the dressing tool in such a way that their peripheral speeds are the same and their rotation ratio to the grinding wheel Whole number is not sufficient grinding effect due to a relative cutting speed between the grinding wheel and workpiece on the one hand and grinding wheel and dressing roller on the other.
  • this can be achieved if, according to the invention, an inclination takes place from the grinding wheel to the workpiece and with respect to the dressing roller. This results in an increased grinding effect, which shortens the grinding process.
  • both the diamond dressing roller and the grinding wheel have an involute-shaped tooth profile, for example.
  • This profile is transferred from the grinding wheel to the workpiece.
  • the toothing on the workpiece can be ground directly into the solid if it is a very small module, or a toothing on larger modules can only be reground after hardening be, as is common in technology on other machine equipment.
  • the diamond dressing roller together with the grinding wheel and the workpiece form a type of gear, the kinematic coupling or the inevitable drive of the diamond dressing roller and workpiece taking place in relation to the number of teeth provided.
  • An essential feature or configuration of the invention can be seen in an inclined position of the grinding wheel from a common plane between the diamond dressing roller and the workpiece, for example by an angle of 25 ° in the axial direction of the grinding wheel.
  • Such an inclination is required in order to produce a grinding effect at the given cutting speeds, the grinding direction forming a resultant from the circumferential speed direction V s of the grinding wheel and the resulting speed V r in the axial direction of the workpiece.
  • the method of kinematically coupled grinding according to the invention is not limited to the machining of profiles of the type described above. Rather, by choosing the speed ratio between grinding wheel and workpiece with a single-profile profiled grinding wheel and a single-purpose dressing roller, multi-start threads of different pitch on the workpiece getting produced.
  • the arrangement shown in the drawing for grinding a workpiece 5 has a grinding wheel 1 with a profile 2, with which a dressing roller 3 is kinematically coupled, which in turn carries a profile 4.
  • Grinding wheel 1, dressing roller 3 and workpiece 5 have different diameters D1 or D3 and D2.
  • the peripheral speeds between the workpiece 5 and the grinding wheel 1 are different. They can be selected and changed by a mechanical coupling in this example between the grinding wheel 1 driven by its shaft 8 on the one hand with the workpiece 5 and on the other hand with the dressing roller 3.
  • the drive shaft 8 of the grinding wheel 1 is provided with a roller 9 on the two endless belts 14 and 16 for driving the dressing roller 3 and the workpiece roller 5.
  • the workpiece 5 is driven by the belt 16 via the deflection roller 13 and a further belt 17 via the roller 11 of the tool and the drive of the dressing roller 3 via the belt 14 and the deflection roller 12 as well as a further endless belt 15 and the disk 10.
  • the rollers 12 and 13 are to and fro according to the double arrow 12 pivotable and designed so that the directions of rotation are reversed from the input to the output side, so that the dressing roller 3 and the workpiece 5 both rotate counterclockwise according to the arrows.
  • the grinding of a profile on a polygonal workpiece 5 using the straight plunge grinding method is normally carried out in accordance with FIG. 2 using a grinding wheel with a circular circumferential surface on a cylindrical grinding machine with two supports, one of which requires support, in order to move the grinding wheel 1 perpendicular to the axis of the arrow 21 To move workpiece 5 forward and backward in order to generate the necessary profile.
  • the movement of this support in accordance with double arrow 21 is kinematically coupled to the workpiece 5 to be ground via a corresponding gear.
  • the second support available in known cylindrical grinding machines serves to bring about the required infeed movement during grinding according to arrow 20, which is only a hundredth of a millimeter in contact with the workpiece emotional.
  • the grinding wheel 1 Due to the mechanical or kinematic coupling of the grinding wheel 1 with the workpiece 5 according to FIG. 1, it is possible, according to FIG. 3, with a suitably shaped grinding wheel 1 while omitting support with the reciprocating movement according to arrow 21 in FIG. 2 only under continuous infeed according to arrow 20 to grind a polygonal workpiece 5.
  • the grinding wheel 1 is approximately star-shaped. That is, the grinding wheel 1 is provided with three arcuate depressions arranged uniformly distributed over the circumference, the diameter difference t 2 forming, ie the difference between the smallest and the largest diameter of the grinding wheel in relation to the circumferential direction.
  • This difference t2 which is also referred to as the amplitude above, corresponds to the difference t1 of the workpiece, which results from the largest and its smallest diameter in cross section.
  • the grinding wheel 1 for performing the method is inclined to the plane between the diamond dressing roller 3 and the workpiece 5, namely by an angle of 25 °.
  • Such an inclination is necessary in order to produce a grinding effect at the given cutting speeds, V s forming the speed of the grinding wheel and V r the resultant in the axial direction of the workpiece, which produces the grinding effect, as can be seen in FIG. 5.
  • the new method of kinematically coupled grinding is not only limited to the profiles described above, for example those according to FIG. 3. Rather, by selecting the speed ratios between the grinding wheel and workpiece with a single-profile profiled grinding wheel and a single-purpose dressing roller, multi-start threads of different pitch can be produced. If the grinding wheel and workpiece have the same rotational speeds in the case of a single thread of the grinding wheel 1, then a single thread also becomes on the workpiece 5 generated. If, on the other hand, the speed of the workpiece 5 is doubled, for example, a two-start thread is created.
  • the pitch of the thread can also be changed from left-handed to right-handed, for example.
  • Grinding disks with a wide variety of profile designs, for example as shown in FIG. 6, can also be used.
