Definitions

  • the invention further relates to a grinding machine for centerless Oblique plunge grinding on one around a first axis rotatable workpiece with essentially cylindrical sections of different diameters and at least one between the sections lying on the shoulder, one on her Scope of conical grinding wheel around its, to the workpiece axis axis rotatable by a predetermined angle arranged and with at least one surface line of the circumference in Engagement with the workpiece can be brought, and while still the grinding wheel and the workpiece by a predetermined allowance are deliverable relative to each other.
  • the invention is based on the object of a method and a grinding machine of the aforementioned type to further develop the disadvantages mentioned above be avoided.
  • a secure location, condition should be available at all times and system of the workpiece can be guaranteed so that only one defined movement of the workpiece is possible. Also supposed to be ensured be that the workpiece by an appropriate Sufficient radial force is applied to the regulating wheel and therefore the drive of the workpiece is guaranteed. After all, it should be possible to remove the material in the area of cylindrical sections of the workpiece and the shoulder separately adjusted according to the respective circumstances.
  • This measure has the advantage of further differentiation the delivery movement different areas of the The workpiece is approached in a defined manner and the measurement in these areas in different steps and therefore different is adjustable adjustable.
  • the workpiece axis is kept stationary and the grinding wheel in moved radially and in the axial direction relative to the workpiece axis.
  • This measure has the advantage that a simple constructive Design of the required grinding machine is possible, in which the movement processes by means of a cross slide or the like the grinding wheel and thus all movement processes between grinding wheel and workpiece. can.
  • the infeed movement is preferably by overlaying Sledge movements generated, all possible combinatorial Swap directions are possible.
  • the grinding machine 10 comprises a first carriage 12 which designed as a cross slide.
  • the first carriage 12 is thus linearly adjustable along the axes indicated at 14, namely the so-called Z-axis and the so-called X-axis.
  • a grinding wheel 16 with associated drive 18 is on the first carriage 12 attached.
  • An axis 20 of the drive 16 is inclined to the Z axis by an angle ⁇ .
  • the angle ⁇ is preferably in the range between 10 ° and 30 °.
  • the grinder 10 further includes a second carriage 22, which is also designed as a cross slide and thus along the axes indicated at 24, namely the Z axis and the X axis is movable.
  • a second carriage 22 which is also designed as a cross slide and thus along the axes indicated at 24, namely the Z axis and the X axis is movable.
  • the first carriage 12 insofar as can also be moved along the axis, which is not under at a right angle to the longitudinal axis of the grinding machine 10 runs.
  • the second carriage 22 carries a regulating disk 26 with drive 28.
  • the axis of the regulating wheel 26 is designated 30.
  • the workpiece 34 has a shoulder 38, which can be radial or oblique.
  • FIG. 1 also shows a dressing device 40 a first dressing tool 42 for the grinding wheel 16 and a second dressing tool 44 for dressing the regulating wheel 26.
  • 46 is also a longitudinal median plane, the runs parallel to the Z axis and on both sides of it Carriages 12 and 22 are arranged.
  • the workpiece 34 is located on the support 32 essentially in the longitudinal median plane 46.
  • the workpiece 34 is a thin cylindrical Section 50, a conical transition section 52 and has a thicker cylindrical portion 54.
  • the conical section 52 thus forms a shoulder between the cylindrical sections 50 and 54.
  • the conical section 52 is only to be understood as an example, because in its place a radial ring shoulder could also be provided.
  • the transition between sections 50 and 52 is denoted by 56.
  • the regulating disk 26 is correspondingly larger cylindrical section 60 and a smaller cylindrical Section 62 provided. Sections 60 and 62 are in contact the cylindrical portions 50 and 54 of the workpiece 34.
  • the grinding wheel 16 is in its shape to the shape of the workpiece 34 adapted. Depending on the angle ⁇ points the grinding wheel 16 has a first conical section 66, one second conical section 68 and a third conical Section 70 on. These sections are designed so that they just abut against sections 50, 52 and 54 of the workpiece 34 can be brought by the generatrices of the Lay sections 50/66, 52/68 and 54/70 together. In the Grinding wheel 16 is the transition between sections 66 and 68 at 72.
  • the grinding wheel 16 In order to grind the workpiece 34, the grinding wheel 16 would have to from the position shown in Fig. 2A along an arrow 74 approach the workpiece 34 and then around the desired one Allowances are delivered.
  • the arrow 74 shows that the approach and infeed direction runs inclined to the longitudinal center plane 46. As Fig. 2B shows, the arrow 74 thus decays into a radial component 74x along the X axis as well as in an axial component 74z the Z axis.
  • the infeed movement is now carried out in several Steps performed, with predominance during each step or is delivered completely axially or radially.
  • FIGS. 3A and 3B This is illustrated in more detail in FIGS. 3A and 3B.
  • the workpiece 34 is initially essentially radial Direction is loaded, so that a defined position and movement of the workpiece 34 on its support 32 also ensured is like a secure system on the regulating wheel 26.
  • FIGS. 5A to 5B A refined variant is shown in FIGS. 5A to 5B in one Representation similar to FIGS. 4A and 4B.
