  • Fig. 1 shows a ballpoint pen tip after completion of machining (raw point) with a ball used only for explanation.
  • Such pen tips usually consist of easily machinable, short-chipped brass or nickel silver.
  • a ballpoint pen tip 1 is very complex. in the essentially it has a central feed channel 2 for the ballpoint pen paste, hereinafter Simplified called ink, which in a seat area 3 by means of a bore 2a for the ball 4 opens.
  • This seating area 3 consists essentially of a to the bore 2a subsequent pilot hole 3a, an annular bottom surface 3b and one cylindrical bore 3c, which opens at an end face 3d.
  • the outer contour adjoining the end face 3d consists of a cone 5a which forms the so-called lip 9 together with the seating area 3. Connects to the cone 5a in the illustrated embodiment, a cone 5b on a shoulder 5c, the Training and function is explained below. This is followed by one Shoulder 6 and a shaft 7.
  • Ballpoint pen tip is in the range of less than one Dollar cents.
  • the pilot bore 3a is exactly concentric with the shoulder 3b and the cylindrical bore 3c.
  • the end face 3d must be exactly rotationally symmetrical to the axis 3e of the seating area 3 be formed.
  • the cone 5a must also be arranged exactly concentrically to the axis 3e his.
  • the "form and position deviations" are under “exact” understood to the extent of 0.001 times the nominal diameter of the bore 3c.
  • pilot hole 3a In addition to the concentricity between the pilot hole and the shoulder, there is also the length pilot hole 3a is important for the following reasons: After machining of the ballpoint pen tip, the ink channels are in the area of the transition created from the pilot bore 3a to the shoulder 3b by means of an embossing tool and it the ball is pressed into its seat in the axial direction. It also has to occur of "flags", which arise during this processing according to the material displacement to the axis back can be ensured that the ink flow in the finished ballpoint pen tip can be done properly, which is indicated by a sufficient depth of the pilot hole is ensured.
  • Fig. 1 shows on its left side the shape of the cold-pressed blank 8 from the in As a result, the holes 2 and 2a, the seating area 3 and the cone 5a were machined becomes.
  • Fig. 1 also shows a fictitious ball 4 around the protrusion of the ball over the Illustrate end face 3d.
  • ink channels are embossed into the annular seat 3b, the ball becomes inserted, pressed into the seat and the lip area is crimped around the ball.
  • flanging for example with a spinner head, a microscopically precise, narrow, annularly curved gap is formed concentrically around the ball 4 and to the seat. The geometrical accuracy of this gap is a prerequisite for a quality ballpoint pen tip.
  • the bearing of the precision spindle consists of strongly preloaded ball bearings with a Contact angle between 15 ° and 30 °, preferably hybrid bearings, of the highest accuracy class (ABEC 9) in a spindle housing, the accuracy of which is IT 01 to IT 1, Dimensions, cylindricity, concentricity, parallelism, lies.
  • the surfaces that are used for recording of the bearings used should not exceed a roughness of Ra 0.1. Due to these accuracies, the preload of the bearings can exceed the usual limits out without causing undue heating of the spindle.
  • Lubrication system of the bearing is suitable for example oil mist. It is also a non-contact Seal to limit the frictional heat, for example a labyrinth seal, necessary. With such spindles, concentricity can also be controlled become.

  • This Tool is made from a cylindrical rod with a diameter of, for example 4 mm, with a roundness and cylindricity whose deviation is less than 0.5 ⁇ m, manufactured. This accuracy can be achieved by centerless grinding.
  • monolithic tool 10 has a base region 10a, which explained the above Has roundness and cylindricity and serves as a reference.
  • the base area is preferred 10a at an axial distance from the seat area element (preferably 1.5 mm distance formed by the edge 10b) along its entire circumference.
  • At the top" Area is the base element along edge 10b, the appropriate distance (at least 51% of the diameter of the bore 3c, Fig. 1) from the center, parallel to the axis 16, graduated in the axial direction to the complete base area. This gradation creates the space for a tool part, not shown, which forms the cone area 5a.
  • the seat area element 12, which is the pilot bore 3 a projects from the base Bottom surface 3b, the cylindrical bore 3c and the end face 3d forms.
  • the seat area element 12 has a multiple kink Cutting contour 14, which consists of the following sections:
  • the top section creates the transition from bore 2a to pilot bore 3a, the following section the pilot hole 3a, the annular bottom surface 3b, the cylindrical hole 3c and finally the end face 3d.
  • the cutting contour 14 lies in a breast plane 12a is preferably 0.05 to 0.1 mm above the center of the base 10a (indicated by the Point of intersection of the axis 16 in the surface 12c). This enables the open spaces 12b to form normal to the chest surface 12a, thereby creating a mechanically stable, wear-resistant Cutting geometry is achieved.
  • a correction regarding the diameter of the seating area can be done without removing the one-piece tool part 10, which has the seat area element 12, from the clamping device by moving transversely to the axis 16, the individual Distances of the sections of the seating area 3a, 3b, 3c and 3d on the tool to each other cannot change due to its one-piece nature. By the shift the diameters are only changed simultaneously by the same value. If the If the diameter reaches the desired value, it is also the right thing to do The ball protrudes beyond the end face 3d.
  • This one-piece tool 10 for the seating area is, as explained above, by a Part not shown for the cone area 5a and preferably the shoulder 5c supplemented.
  • the above-mentioned problems of multi-part tools only play one role here negligible role, since the one-piece tool 10 does not have to be removed and due to possible deviations when re-clamping the cone element only that Wall thickness of the lip 9 (Fig. 1) can vary in the micrometer range, but not theirs Concentricity suffers.
  • This independent cone section gives you the option of by sliding it with respect to the one-piece part 10 along the edge 10b limited, parallel to the axis 16 plane, the thickness of the lip 9 independently influenced by the diameters of the seating area 3.
  • FIG 3 and 4 show a tool according to the invention, in which both the seat area element 12 and a cone element 13 in one piece on a common base part 10a are formed.
  • the cone element forms 13 the cone 5a and the shoulder 5c (Fig. 1).
  • the cone element 13 has a chest surface 13a, which is preferably through the center of the Base 10a goes (through axis 16) and an angle larger with respect to chest surface 12a than 90 °, preferably about 120 °. This way you can achieve both Space for the removal of the chips from both cutting contours 14, 15 and sufficient mechanical Strength of both elements 12, 13.
  • FIGS. 3 and 4 shows the depth in the axial direction Incision in front of the chest surface 13a and the groove between the seating area element 12 and the cone element 13. These free spaces can be obtained by the method described below getting produced. 3 also shows the complex design of the tiny ones Surfaces of the seating area element 12, the exact manufacture of which also the procedure described below is enabled.
  • the positioning of the Tool 10 in several steps: First, by moving the tool or its clamping device in the X direction and / or Y direction (which together with the Z direction form an orthogonal coordinate system, the Z direction with the Axis 16 coincides) whose axis 16 corresponds to the axis of rotation of the Brought precision spindle. This is done by turning the spindle into four (related with the breast plane 12a) predetermined and appropriately marked orthogonal positions, determining the distance of the exact cylindrical surface the base 10a at these positions to a fixedly arranged during the positioning process, exact dial gauge (microcator). The deviation found in the X or Y direction is corrected by moving the tool until the deviation below 0.5 ⁇ m.
  • any deviations of the raw points obtained from the desired dimensions can be corrected as follows: To increase the diameter of the seat area 3, it is only necessary to move the tool 10 parallel to the breast plane, thus in the direction of the X axis. In this direction the breast plane 12a has been positioned exactly when the tool 10 is clamped. Since the angle between the breast planes 12a and 13a is greater than 90 °, the diameter of the cone 5a and the shoulder 5c is reduced. This can be compensated for by a corresponding shift towards the Y axis.
  • a tool according to the invention is produced by wire erosion and is made using the high-precision cylindrical rods mentioned above Shell surface in the base part 10a possible.
  • the wire is first created using a small one Voltage (for example 10V) approximates the cylindrical surface of the rod, until a contact takes place, whereupon the precise formation of the stick is followed an exactly reproducible and precisely defined position of the wire, actually its outer surface, relative to the rod axis 16 is available. It is therefore possible, despite various Implementations or reclamping operations of the tool 10 or the Wire, the various edges, surfaces and grooves of the tool 10 with the required To produce accuracy.
