Definitions

  • the invention relates to a method for cylindrical grinding of long, thin round rods according to the preamble of claim 1.
  • a method of this kind is known from DE 103 08 292 B4 the applicant known.
  • the known method is intended for the production of tools made of hard metal, which is especially intended to round rods made of sintered cemented carbide as a starting material.
  • the known method is "worked from the running rod", ie the forming the starting material round rod, the length of which is a multiple of the length of the individual tool is gradually pushed through the chuck of the workpiece headstock and each tightened when a certain, the to be produced tool in its length approximately corresponding end portion of the round rod protrudes from the workpiece headstock and faces the tailstock.
  • the procedure is imperative that the outstanding end area is clamped during cylindrical grinding between the workpiece headstock and a tailstock. Therefore, a front cone must be sanded with great accuracy to the initially still free end of the round rod, which is to be retracted for tightening in a hollow body, which is located on a quill of the tailstock.
  • a cylindrical grinding machine which is also intended for grinding long, thin round rods. With this machine in particular length / diameter ratios of more than 100 are to be achieved.
  • a workpiece headstock in the direction of its spindle axis, which is at the same time the axis of rotation of the clamped workpiece, arranged displaceably on the machine bed.
  • the long, thin workpiece clamped in the workpiece spindle (quill) is moved with its free end between two grinding wheels whose axes of rotation run parallel to that of the workpiece.
  • the two grinding wheels are located approximately in the same radial plane and leave between them a gap, in which the workpiece can retract.
  • the two grinding wheels one of which can be used for roughing and the other for fine machining, are in a direction perpendicular to their axes of rotation to the Delivered workpiece.
  • a support with a V-shaped recess is arranged; a separate pressure roller causes the workpiece is held firmly in this recess.
  • the known cylindrical grinding machine according to the DE 694 21 859 T2 should work so that the workpiece headstock guides the workpiece in its axial direction along the grinding wheels until the entire length of the workpiece's ground diameter is ground. In this case, however, the workpiece lies in the recess of the support with a peripheral surface which is not to be machined in this machine, and the workpiece must rotate with this peripheral surface in the recess. This is only possible with regard to the grinding result when the workpiece is already ground on its cylindrical shank. With the cylindrical grinding machine according to DE 694 21 859 T2 Thus, no workpieces can be ground that still have their - for example turned - raw contour.
  • peel grinding the outside diameter of a workpiece to be produced is ground in a single longitudinal stroke. This brings with it the difficulty in measuring and controlling that the already ground Au- ⁇ diameter can not be corrected later if the specified size is exceeded.
  • the proposal of the DE 198 57 364 A1 During grinding, the workpiece is permanently and continuously measured to the present actual dimension and at the same time the measured actual dimension is continuously corrected automatically to a predetermined grinding time-dependent nominal dimension. In this way it is avoided that the workpiece to be ground is ground to undersize.
  • the invention has for its object to provide a method of the type mentioned, which works quickly and economically, is easy to perform and leads to grinding results of high accuracy.
  • the principle of the method according to the invention is based on the fact that in grinding operation, the grinding wheel and the steady rest together form an operational solid unit and that this unit is moved relative to the round rod in the longitudinal direction.
  • the fixed longitudinal assignment is given by the fact that the bezel rests against the already ground by the peel grinding part of the round rod.
  • the bezel is thus opposite the grinding area - this is the area in which the grinding wheel touches the round bar - offset laterally towards the workpiece headstock out.
  • the grinding wheel is always the first on the uncut round bar effective, so that one can also speak of a caster of the bezel.
  • the grinding wheel is no longer active in the ground area of the round bar on which the steady rest rests.
  • “Operationally fixed” in claim 1 means that the steady rest and the grinding wheel must be held at least in grinding operation in this fixed longitudinal assignment. This can be done in a simple manner by a grinding wheel overlapping grinding spindle is mounted together with the steady rest on a carriage or grinding table, which is axially moved relative to a fixed workpiece headstock in which the round bar is clamped.
  • the method according to the invention has the advantage that the steady rest is always effective close to the grinding wheel.
  • a single bezel is sufficient, because it always stands at the optimum position.
  • the arrangement of other lunettes is in case of need for particularly long and prone to sag round rods but not excluded.
  • the support on the already ground by longitudinal grinding area of the round bar leads to a safe and accurate guidance and is another prerequisite for a grinding result of high accuracy.
  • the method can therefore still be carried out by peeling grinding, and the round rods can be clamped with their rough contour in the workpiece headstock.
  • the secure support of the round rod close to the grinding wheel brings with it the further advantage that the method can be carried out solely with flying clamping of the round rod in the workpiece headstock; It is therefore not essential to support the other end of the round rod in a tailstock.
  • the in-process measurement and control of the ground diameter will also be carried out in the method according to the invention. Since the steady rest must be offset laterally in the direction of the workpiece headstock relative to the plane of rotation of the grinding wheel, the feeler elements of a measuring device can still be brought into contact with the round rod in the grinding area of the grinding wheel. This is the peripheral area on the round bar that is touched by the grinding wheel. The measurement takes place at the finished dimension of a grinding pass.
  • the inventive method can be carried out with particular accuracy by constantly adjusting and correcting the looping intervention.
  • the method according to the invention is carried out with an automatically adjusting and centering steady rest. This ensures that the axis of rotation of the rotating round rod is always held in the position predetermined by the workpiece headstock. It can thus achieve an optimal grinding result.
  • Such a grinding machine can be carried out in a particularly simple manner in that the steady rest, the measuring point of the measuring device and the grinding spindle are fixedly arranged on a machine bed, while the workpiece headstock in the clamping direction of the rotating round rod, linear and abrasive past the grinding wheel ,
  • the kinematic reversal with a fixed workpiece spindle head and a linearly movable unit of steady rest, measuring head and grinding spindle is relatively easy to perform.
  • Fig. 1 are shown in a view from above schematically the most important parts of a device with which the inventive method is performed. It serves
  • Fig. 1 especially to explain the basic principle of the procedure.
  • 1 denotes the workpiece headstock of a grinding machine.
  • the workpiece headstock 1 serves to accommodate a chuck 2.
  • the round rod 3 so the workpiece to be ground, clamped at one end.
  • the opposite other end may be clamped in a known manner on a tailstock, the in Fig. 1 not shown.
  • the workpiece headstock 1 has an electromotive drive and offset the clamped round rod 3 in rotation about its longitudinal axis. 4
  • the grinding wheel 5 denotes a grinding wheel of substantially cylindrical contour, which rotates about the axis of rotation 6.
  • the grinding wheel 5 is delivered in the feed direction 7 to the round bar 3, and the output diameter D0 of the round bar 3 is reduced to the finished dimension D1.
  • a bezel 9, a Vorablageprisma 10 and the measuring head 13 of a diameter-measuring device on a common base 8 are arranged.
  • the base 8 illustrates that the three mentioned parts 9, 10 and 13 are to form a combined, common assembly which, depending on the embodiment, can also be moved as a whole parallel to the common central axis 4, cf. the directional arrow 15b.
  • the bezel 9 is used in a known manner to support the workpiece and absorb the grinding pressure of the grinding wheel 5 so that it does not bend the workpiece during grinding.
  • the Vorablageprisma 10 is pivotally mounted about a pivot axis 12 on the bezel 9 and serves as a temporary storage for the workpiece during loading and unloading, as will be explained below.
  • the Vorablageprisma 10 is provided with a longitudinal stop 11.
  • the measuring head 13 has one or more movable feeler members 14 which are brought into contact with the grinding area 3c of the round bar 3 in the current grinding operation. This is the peripheral portion of the round bar 3, in which the grinding wheel 5 the Round bar 3 touched.
  • the grinding area 3c lies between the non-ground area 3a and the ground area 3b, against which the steady rest 9 rests with its lunette jaws 19.
  • the sensing members 14 of the diameter reached in the grinding area 3c during the grinding operation is continuously measured and processed via the CNC control of the device to further actuating signals for the grinding wheel 5.
  • the arrangement is such that the sensing elements 14 of the grinding wheel 5 in the grinding area 3c are directly opposite.
  • the directional arrows 15a (grinding wheel 5), 15b (base 8) and 16 (workpiece headstock 1) are essential. It is important that during grinding a relative, oppositely directed movement between on the one hand the workpiece headstock 1 (direction arrow 16) and the other hand, the grinding wheel 5 on the ground workpiece diameter together with the base 8 (directional arrows 15a, 15b) comes about. In this case, one of the two oppositely moved modules can also stand still.
  • the grinding wheel 5 can rest with the associated grinding spindle and the base 8 in the direction parallel to the common center axis 4; then the workpiece headstock 1 is pulled with the round bar 3 in the direction of the directional arrow 16. In this case, the round rod 3 is pulled past with constant reduction of its diameter at the grinding wheel 5, but the bezel 9 is always consistent in the area of the grinding wheel 5. Although there is only a single bezel 9 available, but this always acts at the optimum location.
  • the workpiece headstock 1 could stand still together with the round rod 3, and the grinding wheel 5 would be moved together with the base 8 in the common direction 15a, 15b. Then the grinding wheel 5 moves over the round bar 3 in Fig. 1 from left to right, and the bezel 9 follows the grinding wheel 5 trailing at a small longitudinal distance. It is also achieved that the round rod 3 is optimally supported during grinding. In the two aforementioned cases, of course, the measuring head 13 always remains in its arrangement relative to the grinding wheel fifth
  • Fig. 2 shows details of the assembly consisting of the bezel 9, the Vorprageprisma 10 and the measuring head 13 on the common base 8 in a side view along the line A - A in Fig. 1 , It also corresponds to the one in Fig. 1 shown working phase of grinding. It can be seen that the base 8 is placed on a machine bed 17 and that the Vorablageprisma 10 is located on a pivot arm which can be adjusted about the pivot axis 12. The two possible pivoting directions are indicated by the curved double arrow 18. In Fig. 2 the Vorablageprisma 10 is lowered to its rest position and empty. The round rod 3 is held by the workpiece spindle head 1 at its one end and driven for rotation.
  • the grinding wheel 5 also rotates and is delivered to the round bar 3.
  • the arranged next to the prism lunette jaws 19 are in their extended position, hold the round rod 3 and support it against the grinding pressure.
  • the round bar 3 is with only a small lateral distance from the grinding wheel 5 (see. Fig. 1 ) held and supported by the now extended lunette jaws 19.
  • the mutual assignment of grinding wheel 5 and bezel 9 in the longitudinal direction always remains the same, so that an optimal support of the round bar 3 and thus a high grinding accuracy is guaranteed.
  • FIG. 3 Another working phase in the same direction A - A from Fig. 1 is in Fig. 3 shown. This is the working phase of loading and unloading.
  • the grinding wheel 5 is moved back, and the workpiece spindle head 1 stands still.
  • the prewar prism 10 is raised to its upper position, which is the loading and unloading position.
  • On the Vorprageprisma 10 rests in Fig. 1 right end of a round bar 3 and thereby strikes the longitudinal stop 11, see. also Fig. 6 ,
  • the lunette jaws 19 located next to the prewar prism 10 are retracted into their non-abutting position on a workpiece.
  • the lunettes 9 shown here by way of example can not only support the round bar 3 and counteract the grinding pressure, but also act centering. Bezels of this type are automatically tracked very precisely the decreasing diameter of the round rods 3 in the sense of centering. They belong to the state of the art; as an example of many is the EP 0 554 506 B1 called. A more detailed description is therefore not required.
  • Fig. 4 shows in the partially sectioned view along the line B - B in Fig. 1 how the feeler members 14 of the measuring device 13 are employed in their setting 20 to the round rod 3.
  • the measuring devices of this type are also state of the art, cf.
  • Fig. 5 is a view from above a grinding machine shown, which corresponds in its basic arrangement of a universal grinding machine and is adapted to carry out the method according to the invention.
  • a guide carriage 21 On the machine bed 17 of this grinding machine, a guide carriage 21 is arranged, which can be moved in the direction 28 (X direction) on the machine bed 17.
  • a wheel spindle 22 On the guide carriage 21 is a wheel spindle 22, which in turn carries a first grinding spindle 23 with a first grinding wheel 24 and a second grinding spindle 25 with a second grinding wheel 26.
  • the wheelhead 22 can be pivoted on the guide carriage 21 about a vertical pivot axis 27 (B-axis).
  • the grinding wheels 24 and 26 of the grinding spindles 23, 25 can thereby bring in and out of operative position.
  • a grinding table 29 is arranged, which can be moved in the direction 30 (Z1 axis).
  • On the grinding table 29 of the workpiece headstock 1 is movably constructed, which has a chuck 2 for receiving the round bar 3 in the manner already described.
  • the electric motor driven workpiece headstock 1 has a central center axis, which is at the same time the axis of rotation of the chuck 2 and the longitudinal axis of the clamped round rod 3. This is already the basis of Fig. 1 introduced common central axis 4 (Z2 axis).
  • the arrangement is designed such that the axes 30 and 4 run parallel to each other and that the workpiece headstock 1 can be moved on the grinding table 29 independently of this in the direction of the common center axis 4.
  • the direction of movement 28 of the guide carriage 21 is directed substantially perpendicular to the two axes 29 and 4 and thus corresponds to the feed direction 7 Fig. 1 ,
  • Shown at 31 are protective covers in the form of bellows which cover the slideways of the grinding table 29 and the workpiece headstock 1.
  • FIG. 5 shown state corresponds to the process step of loading. It should be the round rod 3 with her in FIG. 5 left end are inserted into the chuck of the workpiece headstock 1.
  • the opposite right end of the round bar 3 is placed on the tilted-up Vorablageprisma 10, like that FIG. 3 is apparent.
  • a slight pressure on the end face of the round rod 3 is exerted by the longitudinal stop 11.
  • the contact pressure comes about through a pressure element, here a sprung pressure element in the chuck.
  • the workpiece headstock 1 is moved to the process of loading on a theParknbian the round bar 3 associated distance in its direction of movement 30 to the left.
  • the workpiece spindle head 1 has meanwhile set the round rod in rotation, so that the process of cylindrical grinding by the rotating first grinding wheel 24 can begin.
  • the workpiece headstock 1 is moved continuously in its movement path 30 to the left.
  • the steady rest 9 can now be employed on the workpiece 3 for its support. Referring to Fig. 1 It is clear that, to the right of the grinding wheel 5, the non-ground area 3a of the round bar 3 lies, while the steady rest 9 supports the ground area 3b to the left of the grinding wheel 5. Subsequently, the grinding process is continued, until the entire of the chuck 2 outstanding length of the round rod 3 is ground.
  • the round rod 3 is in a sense pulled through from right to left by the steady rest 9 and is always safely supported and centered. It is ground in peeling process.
  • the lunette jaws 19, the sensing members 14 and the Vorablageprisma 10 are in the position that in the FIGS. 1 and 2 is shown.
  • the diameter of the round rod 3 is thereby reduced from the initial diameter D0 to the final diameter D1 (cf. FIG. 1 ), wherein continuously with the measuring head 13, the diameter reached is measured and corrected and, moreover, the round bar 3 is supported by the steady rest 9 self-centering close to the grinding wheel 5 and 24 respectively.
  • the grinding machines according to Figures 5 and 7 are characterized by particular movement and adjustment between the workpiece spindle head 1 and the common assembly of bezel 9, Vorablageprisma 10 and measuring head 13.
  • This mobility results from the fact that the workpiece spindle head 1 is arranged to be movable on the already movable grinding table 29 itself. It is also the reverse arrangement conceivable, namely that the workpiece spindle head 1 is fixedly connected to the grinding table 29, while said common unit can be moved, for example, on the already mentioned common base 8 in addition to the grinding table 29.
  • This double mobility not only has an advantageous effect on the grinding process itself, but also on the important loading and unloading processes.
  • a workpiece is produced from a round rod 3 by grinding, in which a cylindrical portion 32 of larger diameter D1A is connected to a further cylindrical portion 33 of smaller diameter D1B via a conical connecting portion 34.
  • Such a contour can also be produced by the method according to the invention and the associated grinding machines.
  • the lunette jaws 19 may be provided with wear plates which may be polycrystalline diamond (PCD) or cubic centered drill nitride (CBN). These wear plates are crowned in the direction of the longitudinal axis of the resulting workpiece.
  • PCD polycrystalline diamond
  • CBN cubic centered drill nitride
  • tapered constrictions on the workpiece can be ground in the same procedure as the diameter grinding.
  • the advantageous properties of the CNC control of grinding operations can be advantageously exploited.
  • the generatrix of the tapered transition section 34 may be rectilinear or curved.
  • the grinding wheel 5 is again delivered to the round bar 3 until a smaller diameter D1B is reached.
  • a trailing bezel 9 ie the lunette jaws 19 are self-centering during the delivery of the grinding wheel 5 to the smaller workpiece diameter.
  • the round bar 3 is continuously supported.
  • grinding can be carried out in the procedure already described. It is thus again set the axial distance between the lunette jaws 19 and the grinding wheel 5.
  • the round rod 3 is now guided along again in the usual manner on the grinding wheel 5 in the longitudinal grinding feed. This procedure is only possible because the already described double mobility of workpiece headstock 1 and grinding table 29 is given. Furthermore, this procedure is bound to the fact that the changes in the diameter remain in the grinding, so the maximum cutting depth for the grinding wheel during peeling grinding is not exceeded. If this is the case, the workpiece is ground in several cuts to finished size.
