Definitions

  • the invention relates to a device for bilateral Finishing or superfinishing disc-shaped Workpieces or workpiece surfaces with planners and / or spherical surface.
  • Such devices are e.g. from EP 640 436 A1 or EP 640 437 A1 known.
  • EP 640 436 A1 or EP 640 437 A1 known.
  • These two publications concern an apparatus and a method for fine grinding a Brake disc ring of a brake disc, the tool via an articulated holder relative to the one to be processed Surface is adjustable.
  • the invention has for its object a device of the type mentioned in such a way that with her disc-shaped workpieces optimal on both sides can be edited at the same time.
  • the Device for double-sided finishing or Superfinishing of disc-shaped workpieces with plan and / or spherical surfaces means for receiving the Has workpiece and is also provided with a first, rotatable in a first tool spindle recorded tool for editing one surface of the workpiece, the first tool spindle in one first orbital spindle is rotatably received and the axis the first tool spindle and the axis of the first Orbit spindle have a first distance from each other, with a second, rotatable in a second tool spindle recorded tool to edit the other surface of the workpiece, the second tool spindle in one second orbital spindle is rotatably received and the axis the second tool spindle and the axis of the second Orbital spindle have a second distance from each other, and when machining the workpiece both orbital spindles and both tool spindles are rotated simultaneously.
  • the means for Picking up the workpiece on its edge surfaces take up.
  • the means for receiving the Workpiece a three-point or three-line bearing.
  • a another embodiment provides that for holding the Workpiece is used.
  • the holding device grips the workpiece on its edge surface, so that the machining end faces are freely accessible.
  • the workpiece is countered by the holding means Rotary movements, radial offset and the like. captured.
  • the Equipping the device according to the invention and the Workpiece removal can be fully automatic, e.g. over a Turret holder or linearly movable holder respectively.
  • the directions of rotation of all Spindles are the same. This has the advantage that within the Spindle drives on devices for reversing the direction of rotation can be dispensed with.
  • the Direction of rotation of the first tool spindle and / or first orbital spindle not equal to the direction of rotation of the second Tool spindle and / or the second orbital spindle.
  • the control drive is integrated in conventional machines possible without any problems.
  • Optimal work results are achieved in that the Axes of the two tools by one different from 0 ° Angles, in particular offset by 90 ° to one another. On this way only grips sections of the workpiece a tool and grip other sections of the Workpiece both tools at the same time. Also takes effect on still other sections of the workpiece none of the Tools so that these sections are cleaned and / or can be cooled.
  • the axes of the tools advantageously run around the Center of the workpiece, in particular circular.
  • the angular offset of the two tools is preferred when the tools rotate around the center of the Workpiece constant. In this way, be optimal Machining conditions where high Cutting performance, tight tolerances, optimal surface quality etc. are maintained.
  • One embodiment provides that the axes of the Tool spindles mechanically or electronically coupled are. With electronic coupling there is also Possibility of being targeted in the process flow can be intervened, e.g. initiated by in-process measuring devices.
  • the axes of the Orbital spindles mechanically or electronically with each other be coupled.
  • the axes of the orbital spindle one in the horizontal and / or vertical level adjustable from 0 ° have different angles to each other.
  • the tool is preferably a cup grinding wheel or a Slip ring. This has the advantage that the on the workpiece essentially engaging surface of the tool constant distance to the axis of rotation of the tool spindle has, compared to a full area on the workpiece adjacent grinding wheel.
  • the axes of the first and / or second preferably run Orbital spindle through the center of the workpiece.
  • the orbital spindles are coaxial to each other and have a distance from the center of the Workpiece. This configuration means that there are more Variations in the finishing process possible. An additional Variation is achieved in that the speed of rotation at least one of the spindles is variable.
  • FIG 1 In the figure 1 are of a not shown Superfinishing machine two orbital spindles 1 and 2 shown. These orbital spindles 1 and 2 have axes 3 and 4 around which they are rotatable. The drive of the orbital spindles 1 and 2 is not shown and is located inside the housing 5.
  • Tool spindles 6 and 7 are located on orbital spindles 1 and 2 attached, the axes of rotation 8 and 9 each a distance 10th and 27 to axes 3 and 4 of orbital spindles 1 and 2 exhibit. Coaxial to axes 8 and 9 are on the Tool spindles 6 and 7 tools 11 and 12 attached.
  • the Spindles 1 and 2 as well as 6 and 7 as well as tools 11 and 12 rotate in the direction of the through axes 3 and 4 as well as 8 and 9 drawn part-circular arrows.
  • the tools 11 and 12 are as cup grinding wheels 13 and 14 trained.
  • This Workpiece 17 has parallel end faces, which of the both tools 11 and 12 are machined plane-parallel.
  • the workpiece 17 can also have one or two be concave or convex end faces that can be processed using the two tools 11 and 12.
  • the two axes 3 and 4 of the orbital spindles 1 and 2 in the horizontal plane and in the vertical plane in the direction of arrows 20 and 21 or angularly adjustable in the opposite direction.
  • Axes 3 and 8 or 4 and 9 can intersect or skew to each other.
  • FIG 2 the two tools 11 and 12 and that Workpiece 17 shown.
  • the center of the workpiece 17 is designated 22. Run through this center 22 axes 3 and 4 of the two orbital spindles 1 and 2.
  • the two centers of the workpieces are 11 and 12, whereby through these centers 23 and 24 the axes of rotation 8 and 9 of the tool spindles 6 and 7 run.
  • the axes of rotation 8 and 9 of the tool spindles 6 and 7 as well of the tools 11 and 12 move in an orbit 25 or on a circular orbit with a diameter of 26 owns.
  • the diameter 26 corresponds approximately to that twice the distance 10 and 27 of the axes 3 and 8 of the Spindles 1 and 6 or axes 4 and 9 of spindles 2 and 7.
  • the size of the tool 11 and 12 is chosen so that the Area where both tools 11 and 12 work simultaneously attack both end faces of the workpiece 17, in the essentially in the area of the center 22.
  • One-sided loads that may lead to deformation could be avoided in this way.
