Definitions

  • Such a grinding method is known from DE 42 40 053 A1 known.
  • the narrow sides of the indexable insert are ground in this known method with a narrow grinding wheel, which has a cylindrical peripheral contour.
  • the grinding wheel is driven by a grinding spindle, which is displaceable in two mutually perpendicular horizontal planes.
  • the indexable insert is located in a clamping device which is pivotable about a vertical axis.
  • the clamping device has two Einspannstempel, which clamp the indexable insert on their broad sides between them and drive for rotation. By the clamping device around the vertical pivot axis is pivoted, a desired clearance angle can be sanded on the narrow sides of the turning cutting plates.
  • the cylindrical grinding wheel is guided in the operation of the peripheral grinding with radial feed over the side surface of the indexable insert. It contacts the side surface in a straight line parallel to the grinding wheel axis of rotation. A line contact always means a higher heat load for the workpiece.
  • the known method according to the DE 42 40 053 A1 should be improved by then usual grinding methods in which the narrow sides of the insert are ground with cup-shaped grinding wheels.
  • the known method according to the DE 42 40 053 A1 also expressly stipulated that during the grinding of the narrow sides of the cylindrically contoured narrow grinding wheel in the axial direction superimposed for controlled movement reciprocating reciprocated, whereby the engagement of the individual abrasive grains of the grinding wheel is to be constantly corrected. For this reason alone, the axial width of the grinding wheel must be greater than the thickness of the indexable insert.
  • the grinding wheel must therefore have an unnecessarily large width, which is disadvantageous due to the then higher weight in mass production. Further, a large axial extent of the grinding wheel limits the processing capabilities that can be performed on the indexable insert. Moreover, in practice it has been shown that the grinding results did not lead to the hoped-for improvement. Excessively high grinding wheel wear and unsatisfactory precision in the grinding result, ie in the nature of the ground narrow sides, were found.
  • the DE 88 04 567 U1 deals with the so-called deep grinding of cylindrical workpieces.
  • a rotating grinding wheel is guided by a cylindrical contour with considerable grinding depth along the workpiece circumference and parallel to its longitudinal axis.
  • the axis of rotation of the grinding wheel can be made slightly inclined parallel to the workpiece longitudinal axis or opposite to this according to the so-called Quickpoint principle.
  • the largest part of the material removal from the cylindrical outer wall of the workpiece is performed by the in the feed direction forward outer edge of the grinding wheel, and especially with the outer annular zone of the grinding wheel side surface.
  • the abrasive coating has a rough grinding wheel specification.
  • the rear area adjoining the front area of the grinding wheel has a finer specification grinding surface; he should improve when driving over the cylindrical workpiece, especially its surface.
  • the grinding wheel proposed there is used especially for roughing.
  • the direction of the DE 88 04 567 U1 goes to the fact that the front in the feed direction edge region of the grinding wheel end face is not rounded off by wear, so that forms a so-called roof profile.
  • the Fig. 3 of the DE 88 04 567 U1 is such, caused by wear disadvantageous roof profile specially shown. It is that the front outer edge of the grinding wheel is rounded, the rounding passes through both areas of the abrasive coating.
  • the proposed modified grinding wheel specification is intended to prevent a rounded contour of the grinding wheel and to ensure that the desirable, strictly cylindrical contour of the grinding wheel is maintained as long as possible during the grinding operation.
  • the invention is based on the object to provide a grinding method of the initially mentioned type, with the inserts are produced in an economic mass production, in which the narrow sides even with the use of difficult to machine sintered sintered last have a perfect condition and the desired dimensional , Form and position tolerances are met.
  • a first solution of this object is achieved with the entirety of the features of claim 1.
  • a grinding wheel which has a forwardly tapered lead area and an adjoining cylindrical caster area.
  • the grinding process is carried out in such a way that the lead-in area, which forms a lead angle with respect to the contour of the indexable insert, performs a longitudinal grinding on the principle of peel-grinding, thereby first passing over the narrow side of the indexable insert.
  • the lead-in area causes pre-grinding, for example roughing.
  • the lead-in area removes most of the grinding allowance.
  • a second solution of the object underlying the invention is achieved by the entirety of the features of claim 2.
  • the Applicant has found that a slight pivoting of the grinding wheel relative to the indexable insert can lead to similar good results as the orientation perpendicular to the respective contour of the narrow side during grinding according to the first solution.
  • the grinding wheel forms a leading angle in the lead-in area and in the trailing area a clearance angle with respect to the narrow side of the indexable insert to be ground.
  • the trailing region of the grinding wheel is cylindrically contoured as in the procedure according to claim 1.
  • the grinding wheel is then abrasive only with the tapered feed area up to the largest grinding wheel diameter.
  • Clearly lead angle and clearance angle lead to a further improvement of the cooling conditions.
  • the method according to claim 2 can also be done by peel grinding.
  • very hard sintered materials u u. U. perform the pre and regrinding with two different grinding wheels. If, however, the trailing region is likewise tapered starting from the largest diameter of the grinding wheel, a larger starting angle and a larger clearance angle result, without the grinding wheel having to be tilted or pivoted particularly strongly in relation to the indexable insert.
  • a third solution of the problem underlying the invention is set forth in claim 3.
  • the applicant has found that the trailing area can even be completely eliminated and that the procedure according to claim 2 can also be carried out with a grinding wheel having in its peripheral region a tapered, for example tapered, contour and with the small diameter ahead on the narrow sides the indexable insert is guided.
  • the advantage of this solution is based to a very special extent on the thereby improved cooling conditions on the surface of the grinding wheel and the indexable insert
  • the lead-in area is referred to as tapering forward, so it is based on a movement of the grinding wheel relative to a stationary in the axial direction indexable insert. In principle, however, only a relative movement between the indexable insert and the grinding wheel in the feed direction of the longitudinal loops is required, so that the term "to" is only an ordinal specification for the nature of the grinding wheel.
  • indexable inserts with a clearance angle have a larger and a smaller broadside
  • both directions of movement are possible, ie moving the cutting plate from the small broadside to the larger broadside and vice versa.
  • the taper of the lead area and / or the trailing area (claims 1 and 2) or the entire tapered contour of the rotating grinding wheel (claim 3) are formed as a conical surface.
  • the visible in longitudinal section circumferential lines of flow area, trailing area or grinding wheel are then straight.
  • the tapers can therefore also arched, z. B are executed as spherical surfaces or as fillets, where it depends very much on the special process control of the abrasive material to be ground
  • the grinding wheels required to carry out the methods according to the invention retain a relatively simple construction. Since the basically disc-shaped basic shape of the grinding wheel is maintained, the mutual accessibility of the indexable insert with the circular contoured circumferential surface, but also with the side surfaces of the grinding wheel, presents no difficulties. According to a further advantageous embodiment of the According to the method of the invention, it is therefore readily possible to also grind the chamfers of the indexable insert located between the narrow sides and the broad sides in the same clamping with the side surfaces of the rotating grinding wheel. With one and the same grinding wheel, the narrow sides of the indexable insert and the chamfers can thus be ground in one and the same clamping, which are arranged between the individual flat narrow sides or between the narrow sides and the broad sides of the indexable insert.
  • the invention also relates to the use of a special grinding wheel for carrying out the grinding method according to claim 1 or 2 and the dependent claims 4 to 6 and 8 to 10 according to claim 11.
  • the cutting material material located on the circular contoured circumferential surface of the grinding wheel consists of diamond grains with a ceramic or metallic bond, the grinding wheel specification differing in the leading and trailing regions.
  • the cutting material and its binding can be parked in the lead area especially on the needs of roughing and in the trailing area on the sizing, so z. B. be executed finer.
  • the use also includes a grinding wheel in which an abrasive coating is also provided on the side surfaces of the grinding wheel for grinding the chamfers, which may then again have a grinding wheel specification that is different from that in the circular contoured peripheral surface of the grinding wheel.
  • the grinding wheel can have the taper of the lead-in area and / or of the trailing area in the form of a conical jacket, without it being necessary to stipulate for reasons of grinding technology.
  • FIG. 1 is a view from above schematically illustrated a grinding machine, as it corresponds to the usual universal round and -Unrundschleifmaschine. Only the essential parts are shown.
  • a grinding table 2 in the direction of a first displacement axis 3 is movable.

  • the indexable insert 10 to be ground can be fastened and centered and clamped by the pressure pin 9 of the tailstock 7.
  • the indexable insert 10 can be driven in rotation by the workpiece spindle 4. During grinding, therefore, the indexable insert 10 rotates about the driven axis of rotation 11. This is generally referred to as C-axis in grinding machine construction.
  • a wheel spindle 12 is arranged, which can be pivoted about a plane perpendicular to the plane of the pivot axis 13.
  • the pivot axis 13 is commonly referred to as B axis.
