Definitions

  • the invention relates to a grinding machine according to the preamble of claim 1. Grinding machines for grinding (removing) turning tools are widely used.
  • the invention is therefore based on the object of developing a grinding device which meets the special requirements for a cutting edge shape for inclined cutting knives for machining cylindrical bores.
  • the cup shape of the grinding wheel takes into account the stressed displaceability of the clamping device, whereby the machined cutting knife is guided past the cylindrical inner wall of the grinding wheel axially to the axis of rotation of the grinding machine spindle, as is the case later when machining the bore, and the inner surface of the bore is ground accordingly. Since not a ent for every bore diameter Voice S is chleifusionninnen fashionr available, to adapt to the desired bore diameter by a changed inclination of the support segment is reached to the spindle axis.
  • the cutting edges Due to the inclined position of the cutting surfaces of the cutting knives - in particular the secondary cutting edges - relative to the longitudinal axis of the bore, the cutting edges are given a convex shape.
  • the clamping means for each diameter of the bore to be manufactured must be pivoted about their axis parallel to the axis of rotation of the grinding wheel, in order to be able to impart the correct flank angle to the cutting knife.
  • the flank angle is determined by pivoting the carrier segment about the pivot axis of the clamping means parallel to the spindle rotation axis of the grinding wheel.
  • the design of the grinding machine according to the invention with this further axis of rotation for the clamping means is a special feature for cutting knives whose flank angle must be varied. Furthermore, for the correct choice of the inclination of the cutting edges around the swiveling axis crossing the grinding wheel spindle axis, it is important that the center point of the circular segment coincides with the longitudinal center of the cutting edge to be machined, since the cutting edge curvature is also determined by the pivot point of the carrier segment.
  • the plane of the circle in which the cutting knife clamped in the carrier segment is pivoted is parallel or almost parallel to the tangential plane on the circumference of the grinding wheel in which the cutting knife is here Workpiece touching the grinding wheel.
  • the fact that different longitudinal sections of the cutting edges of a cutting knife have to be machined can be taken into account, taking into account the inclined position of the knives.
  • Claim 3 can be provided. This ensures that the flank angle can be varied without changing the other parameters.
  • the grinding machine 1 consists of a table 7, clamping means 8 arranged thereon for a cutting knife 2, and a cup-shaped, hollow-cylindrical grinding wheel 6 which is attached to a spindle 5 on the end face.
  • the grinding wheel rotates about the axis of rotation 9 of the spindle 5 in the direction of the arrow 20.
  • a rail 21 is arranged on the clamping table 7 parallel to the axis of rotation 9 of the spindle 5.
  • the clamping means 8 are pushed back and forth along this in accordance with arrow 10. This movement can be carried out by hand or by a motor, not shown.
  • the carriage 16 slides directly along the rail 21. It has a bore into which a bolt 18 of a clamping head 17 engages.
  • the clamping head 17 can be rotated according to arrow 22 with the bolt 18 in the bore of the carriage 16 and can be locked in the selected angular position by the laterally slotted design of the carriage and the clamping screw 23.
  • the clamping head 17 has at its end on the grinding wheel side a circular segment-shaped guide 12 in which a carrier web element 15 is screwed in an angle-adjustable manner according to arrow 31.
  • the center point 13 of the pivoting movement of the carrier segment 15 coincides with the longitudinal center of the machined cutting edge. (See Fig. '2)
  • the axis of rotation 9 of the spindle 5 runs parallel to the axis of rotation 11 of the bolt 18.
  • the axis of rotation 11 passes through the center of the circle of the segment-shaped guide 12. This center point and the longitudinal center of the secondary cutting edge 3 to be machined coincide.
  • the axis of rotation 11 touches the inner circumference of the grinding wheel 6.
  • another carrier segment 19 is used, which has a corresponding receptacle for the respective position of the cutting knife.
  • the grinding machine is set so that the situation of the cutting knife in the bore is modeled.
  • the inclination of the cutting edge or the cutting surface 30 of the knife 2 is set relative to the longitudinal axis of the bore, or correspondingly relative to the spindle axis 9 (see FIG. 2).
  • This setting is made with the aid of the scale 24 on the clamping head 17 and the pointer 25 on the carrier segment 15.
  • the rotary setting of the clamping head 17 is then carried out using the scale 26 and the pointer 27.
  • the free surface angle of the cutting edge to be machined is specified here.
  • the T support segment 15 is locked in the desired position by the screws 28, 29, the bolt 18 and thus the clamping head 17 is fixed by the clamping screw 23.
  • the whole of the carriage 16, clamping head 17, carrier segment 15 and cutting knife 2 is pushed back and forth along the rail 21 after the grinding machine has been adjusted until the grinding wheel 6 no longer removes the cutting knife.
