Definitions

  • the invention relates to a method for external cylindrical grinding of workpieces with a workpiece diameter (d w ), in which a grinding wheel with a grinding wheel peripheral speed (v s ) bears against the workpiece rotating in opposite directions with a workpiece peripheral speed (v w ) and the Grinding wheel and the workpiece with a feed speed (v fa ) are parallel to the axis of the workpiece relative to each other, wherein the grinding wheel rotates about an axis which is at an angle to the axis of the workpiece and the grinding wheel has a first and a second conical peripheral portion, such that the first circumferential section with a first surface abuts a helicoidal machining surface and the second circumferential section with a second surface abuts an axial circumferential surface of the workpiece.
  • the desired surface roughness can be specified in a wide range in the range of values mentioned.
  • a degree of coverage is determined from the desired surface roughness with the help of empirically obtained relationships as an auxiliary variable, which in turn allows the axial length of the first surface to be determined via the geometry and the operating parameters of the workpiece and grinding wheel. This length can then be adjusted by a suitable choice of the grinding wheel, so that only minimal radial compressive forces, which correspond to the axial length of the first surface, have to be used for the desired surface roughness.
  • a helicoidal machining surface 16 is located between the sections 12 and 13, the oversize being denoted by a.
  • the first and the second conical section 40, 41 form an angle of 90 ° to one another, while the third conical section 42 is slightly flatter than the second conical section 41.
  • the grinding wheel 30 lies against the workpiece 10 in such a way that the first conical section 40 (main cutting surface) with a first surface 44 abuts the helicoidal machining surface 16 and the second conical section 41 with a second surface 45 of the second, machined peripheral surface 15 of the workpiece 10.
  • the third conical section 42 its third surface 46 has a clearance angle 47 to the second, machined peripheral surface 15.
  • This degree of coverage (u) is a direct measure of the surface roughness that can be achieved (R z ) if the peripheral speed (v s ) of the grinding wheel 30 is also taken into account.
  • the dependency of the degree of coverage (u) on the surface roughness (R z ) can be represented by parameterization according to the circumferential speed (v s ) of the grinding wheel 30 in a family of curves, as is shown by way of example and extremely schematically in FIG. 2 for a specific material . It can be clearly seen from FIG. 2 that the surface roughness (R z ) becomes better, ie less, the greater the degree of coverage (u) the higher the peripheral speed (v s ) of the grinding wheel 30.
