Definitions

  • the invention relates to a method for machining bores in workpieces, in which a honing tool coated with an abrasive material and pressed radially against the wall of the bore executes a rotary movement and a stroke movement at the same time. This is the well-known honing.
  • the invention is based on the object of further improving the honing in such a way that greater material removal can be achieved.
  • the "Dorn-' ⁇ onen in which with a slight excess in just one Double stroke is worked, only possible to work off an addition of 4 ⁇ .
  • a higher addition should be possible without higher axial forces and torques occurring.
  • a bore should be formed which, if possible, no longer has a burr and which is also characterized by the highest possible contact area.
  • this object is achieved in that the honing tool performs a high-frequency, short-stroke oscillation in addition to the lifting and rotating movements.
  • a particularly advantageous embodiment of the invention provides that the short-stroke, high-frequency oscillation of the honing tool takes place in the ultrasonic range with a frequency of 20 to 40 kHz and an amplitude of up to 15 ⁇ m and in the axial direction of the bore, so that the machining takes place in just one double stroke , and that the honing tool has a conical cutting zone whose diameter, which is larger in the rear in the direction of the axial lifting movement, has an oversize of more than 4 ⁇ m compared to the diameter of the unmachined bore.
  • the new process enables high machining allowances with relatively fine grain sizes with fine machining surfaces.
  • the previous quality limits of conventional honing are exceeded. So far, values have been around 0.6 m R z as limit for hardened steel. This surface quality could be significantly improved with the method according to the invention.
  • High frequency honing in accordance with the invention results in relatively low machining forces. The result of this is only an extremely small amount of burr formation.
  • a new surface structure is created with a particularly high contact area. Depending on the kinematics, a periodic surface pattern with regular "troughs" or “pockets” is created, which are particularly suitable for accommodating lubricant.

  • FIG. 10 shows a scheme for explaining the honing allowances that can be achieved with the method according to the invention.
  • Figure l shows a honing tool 1.
  • the usual honing movement which results in the cross-section image, is the sum of a rotary movement (corresponding to arrow 2) and a lifting movement, according to arrow 3.
  • these two movement components now have a third movement, namely one short-stroke oscillation in the axial direction, as indicated by the Arrows 32 and 33 illustrated, superimposed.
  • this oscillation takes place at a frequency of 21.7 kHz with an amplitude that could be set to a maximum of 15 ⁇ m.
  • the workpiece 4 has a bore 5 that is to be machined.
  • the honing tool is provided with a conical cutting zone 6, whose - in the direction of the axial stroke - (cf. the arrow drawn) rear larger diameter O ⁇ is larger than the smallest diameter of the honing tool l not yet machined bore 5.
  • the front smaller diameter D 2 allows the introduction of the tool 1.
  • the conical cutting zone 6 moves into the bore 5 and works off the material corresponding to a bore diameter of less than D 1 .
  • the honing tool 1 is cylindrical, so that it is then guided into the part of the bore that has already been machined. Machining takes place with an axial double stroke.
  • FIG. 2 shows the control diagram of the lifting movement at (a), the rotary movement at (b), and the high-frequency vibration at (c) in their association with one another and as a function of time.
  • the broader line at (c) indicates the amplitude of the high-frequency oscillation.
  • the dwell time dt at (a) is adjustable.
  • Points A, B, C, D can also be set, ie the beginning and end of the rotary movement and the high-frequency vibration.
  • the trajectory of a tip of an abrasive grain 7 as a function of time is shown in FIG. 2 in a range from 0 to 300 ⁇ s.

  • FIG. 5 shows a device for carrying out the method.
  • the honing tool 1 ground to fixed dimensions and contour is accommodated in the tool receiving cone 8 .
  • This is located in a sound transmission body 9.
  • Sound transmission body 9 has two flanges 10, 11, which are provided with grooves at points 10', 11' in the offset type shown, so that thin points 10', 11' form, which practically have the effect of a joint, so that an axial high-frequency vibration, which the sound transmission body 9 performs, is not transmitted to the housing 12 in which the sound transmission body 9 is clamped in the manner shown.
  • the sound transmission body is made of titanium so that the thin areas can withstand this.
  • the housing 12 consists of the cylindrical part 13, the lower cover 14 and the upper cover 15.
  • the upper cover 15 has a bore 16 provided with an internal thread in the middle, into which the threaded pin 17 protrudes, which is fixed to the receiving hub 18 connected is.
  • the housing cover 15 and receiving hub 18 are thus firmly screwed together, with the disk 19 being clamped between them.

  • the entire unit, as shown in Figure 5, including a motor (not shown), can be moved up and down for the purpose of generating the lifting movement, as is known per se from conventional honing machines, so that a more detailed description of this constructive Details can be omitted in the present context.

  • a cooling medium can be supplied to the interior of the housing via the line 31 and the openings in the disk 19 and in the cover 15 .
  • Ultrasonic vibration exciter 25 takes place in the manner shown by means of slip rings 35 arranged on cover 15 and slip rings 36 attached to a part of said unit that does not rotate.
  • Figure 6 shows the simplest form of a honing tool 1, which is designed as a fixed mandrel, i.e. mandrel with fixed, non-adjustable external dimensions .
  • the cutting layer has the contour 40 as shown in detail in FIG. 8, namely an introduction zone 37 over less than 10% of its length, followed by the already mentioned cutting zone 6, which extends over somewhat less than half of the entire length length of
  • the cutting means coating extends, as does the cylindrical guide zone 38 adjoining it.
  • a tool is functional in principle, it has the disadvantage that it cannot be readjusted when the cutting means coating 40 is worn.
  • the usual radial opening as is known from honing tools, causes certain difficulties in the present case, since there is a risk that individual mutually adjustable parts that are not in a vibration node rub against each other with the high frequency, so that excessive heating occurs. In addition, it must be ensured that no parts come loose despite the high-frequency vibration. In this respect, specially designed honing tools are advantageous.
  • Such a honing tool 100 is shown in FIG.
  • the cutting layer 40 which has the contour according to FIG.

  • the superimposed high-frequency vibration causes troughs or pockets to form in the surface at short intervals, which are practically “hammered in” or “chiseled in”, whereby - as shown in readily apparent from this photograph - burr-free planar supporting areas are formed which can support bearing parts, and that the pockets or troughs are formed in between and are ideally suited in practice as an oil reservoir for lubricant.
  • the material is removed evenly and a surface pattern that is periodic according to the kinematics is created. It is of course strongly dependent on the set parameters. At a low speed, for example, the cutting marks generated by the high-frequency oscillation are very close together. At high speeds, these cut marks are correspondingly stretched and result in a somewhat less favorable contact area.
  • the wearing percentage was one Test series in approx. 0.2 ⁇ m cutting depth at approx. 30%.
  • machining forces that occur are of particular importance for the application of the method according to the invention.
  • An axial force of 1.0 N and a torque of 1.120 Ncm were determined with an addition of 10 ⁇ m (difference in the diameter of the unmachined bore compared to the final dimension aimed for by machining) using the fixed mandrel with grain size D46.
  • a direct comparison with processing in which the same tool would have been used without high-frequency exposure was not possible, since an addition of more than 4 ⁇ m cannot be achieved without high-frequency oscillation. If you want to remove more material with one stroke without HF oscillation, do this the tool seizes. But even with an addition of 4 ⁇ m without high-frequency oscillation, i.e.
  • FIG. 10 shows the honing allowance dz (in microns) as a function of the grit k (according to the FEPA definition) in comparison between the - known - mandrel honing (lower bar slightly increasing from a grit D15 to D181) in comparison to high-frequency honing ( black filled area).

Abstract

Selon un procédé d'usinage d'alésages de pièces, un outil de honage pourvu d'un revêtement abrasif et pressé radialement sur la paroi de l'alésage effectue en même temps un mouvement de rotation et un mouvement alternatif. Outre les mouvements alternatif et rotatif (2, 3), l'outil de honage (1, 100) effectue un mouvement d'oscillation (31, 32) à haute fréquence et à faible course.
