Definitions

  • the invention relates to a deep hole drill comprising a cutter carrier, a replaceable cutting insert and at least one replaceable guide strip wherein the cutter carrier can be used for a predetermined nominal diameter range, and a range for equipping a cutter carrier for such a deep hole drill wherein a new type of equipping method can be implemented with this range.
  • the swarf is removed by means of a supplied lubricant via the relatively large, straight-grooved machined groove as a result of the single-lip geometry.
  • the actual cutting process takes place by means of a drill cutter which can be located on a cutting plate or a cutting insert, for example which is screwed onto the cutter carrier.
  • the tool is supported over its circumference in the drill hole by corresponding guide strips.
  • Deep hole drills with such replaceable cutting inserts/guide strips are highly economical and have good cutting performance. This is because, when the cutters or the guide strips wear, there is no need to purchase an expensive complete tool but only the relatively inexpensive cutting insert or the guide strip.
  • the cutter carrier can be used not only for one nominal diameter but within an entire nominal diameter range.
  • Such a generic tool is shown for example in the prospectus “Deep hole drills type 01”, No. 01-0501-01 of the company “botek Pr ⁇ zisionsbohrtechnik GmbH”.
  • This drilling tool is fitted with a drill shank soldered to a clamping sleeve and a drill head connected thereto.
  • the drill head has corresponding seats with threaded holes for one cutting plate and for two guide strips by which means the cutting plate and the two guide strips can be screwed to the drill head.
  • the alignment of the position of the cutting edge i.e., the adjustment of the precise nominal diameter within the nominal diameter range for which the deep hole drill is provided is accomplished in this case by means of a replaceable adjustment plate which forms a stop for the cutting plate.
  • the stop is located on the side of the replaceable plate opposite to the minor cutting edge, i.e. before the replaceable plate is attached to the drill head, an adjustment plate suitably selected for the desired nominal diameter is screwed onto the drill head parallel to the longitudinal axis of the tool so that the replaceable plate abuts against the adjustment plate with its side opposite to the minor cutting edge.
  • the thickness of the adjustment plate used thus determines the position of the minor cutting edge and therefore the nominal diameter of the hole.
  • an adjustment wedge is provided for pre-adjustment of the stop surface of the adjustment plate on the corresponding tool back, which can be inserted into a hole ending on the back of the adjustment plate and fixed with a screw.
  • a deep hole drill comprising a cutter carrier which can be used for a plurality of nominal diameters in a nominal diameter range, as well as a replaceable cutting insert and at least one replaceable guide strip, which has a simple structure and allows easy-to-handle and rapid adjustment of the tool to the desired nominal diameter. It is a further object to provide a range of inserts for equipping a cutter carrier for deep hole drilling tools which can be used to implement a new type of cutter carrier equipping method by making available a suitable range of inserts.
  • the new type of equipping method which constitutes an independent invention is characterised as follows: the method allows a cutter carrier of a deep hole drill, which can be used universally within a nominal diameter range ( ⁇ ND), such as for example a drill especially according to one of the present claims, to be equipped according to the nominal diameter with a kit comprising a replaceable cutting insert and at least one replaceable guide strip provided for a certain nominal diameter.
  • the method is characterized by the following steps:
  • kits are associated with the cutter carrier used in a certain nominal diameter range.
  • a kit comprising a cutter carrier and at least one corresponding guide strip is available for each desired nominal diameter.
  • Cutting inserts and guide strips have counter-stop surfaces by which means they can be fixed by means of fixed universally fitting stops on the cutter carrier in the position predetermined by the stops. According to the invention, only the kit corresponding to a desired nominal diameter must be selected from a range of kits and fixed on the cutter carrier by means of the fixed stops thereon.
  • the deep hole drill according to the invention is suitable for diameters, e.g., from 16 mm up to around 40 mm, which are very small compared to the nominal diameters which can be achieved in conventional tools (botek: from 18 mm upwards). Tests have shown that good results are achieved with ratios of drilling depth to diameter of 10:1 to 80:1 with a total tool length of up to 3000 mm.
  • the cutting insert is advantageously screwed to the cutter carrier.
  • a threaded hole is provided on the cutting insert seat on the cutter carrier whereas a through hole is provided on the cutting inserts so that the cutting inserts can be screwed onto the cutter carrier.
  • the distance between the through hole and the counter-stop surfaces is the same for all cutting inserts, i.e. all cutting inserts fit the geometry predefined by the universal cutter carrier.
  • the threaded hole on the cutting insert seat has an offset to a through hole on the cutting insert so that the cutting insert is pressed on the stop when the cutting insert is screwed on the cutting insert seat.
  • the offset is very small (of the order of magnitude of 1/100 mm) so that no deformation of the cutting insert or the cutter carrier occurs but merely to a fixing of the position of the cutting insert at the predetermined stop via the (elastic) deformation of the screw. In this way, equipping the cutter carrier with the cutting insert is further simplified.
  • other fixing possibilities are also feasible as fixing for the cutting insert or the guide strip, for example, a guide groove on the cutter carrier into which a T-shaped wedge molded on the cutting insert is inserted.
  • the guide strips advantageously each have a through hole for screwing into corresponding threaded holes on the cutter carrier.
  • the guide strips inserted in corresponding grooves on the cutter carrier are screwed into threaded holes on the cutter carrier by means of a through hole running in the radial direction.
  • the through hole extends in each case between a supporting or outer circumferential surface and the counter-stop surface of the guide strip.
  • the distance of the through hole to the minor cutting edge of a cutting insert to the next larger increases by the same amount as the distance of the supporting surface and the counter-stop surface of the associated guide strip to the next larger guide strip. This ensures that the minor cutting edge is well supported by the guide strip(s) in the hole over the entire diameter range.
  • the increase can be linear in the entire diameter range or it can follow any other pattern, for example, a similarity series.
  • a suitable set (replaceable plate and guide strip(s)) must be provided for each nominal diameter.
  • the equipping or assembly of the deep hole drill is considerably simplified if the nominal diameter is simply adjusted by selecting the corresponding kit. This is because the iterative process of using turnover plate, adjustment plate, checking measurements etc. is omitted.
  • the adjustment of the nominal diameter is thus removed from the assembly process into a previous production process of the replaceable plates and the guide strips especially for that nominal diameter which takes place under defined conditions and in an automated fashion so that in addition to facilitating the assembly of the deep hole drill, an overall higher precision can be achieved during the adjustment of the nominal diameter.
  • a recess is located on the cutter carrier at the tip of the deep hole drill in the tool face, which is defined by a cutting insert seat by two side surfaces, forming a two-sided stop for the cutting insert. It is particularly easy to equip the cutter carrier thus configured since the cutting insert can be fixed in position in all three coordinate directions using a handle and only needs to be screwed on.
  • the two stop surfaces span an angle smaller than 90° and the side surfaces facing the two stop surfaces span a larger angle, it is additionally ensured that no uncertainty arises in the position of the cutting insert as a result of tolerance deviations in the inclination of the side surfaces towards one another but in any case two-sided stopping of the replaceable cutting plate or the cutting insert is provided.
  • the deep hole drill is advantageously embodied as a single cutter or single-lip deep hole drill.
  • the invention is not restricted to single-lip tools.
  • double-lipped embodiments would also be feasible where a further replaceable plate is provided instead of a guide strip per kit, for example.
  • Triple cutters with three replaceable plates per kit would also be feasible.
  • hard metal cutting inserts and guide strips ensures that the kits for the deep hole drill according to the invention have a particularly high wear resistance.
  • the cutting insert and guide strip have a hard material coating.
  • a combination, that is hard- or soft-coated hard-metal cutting inserts and guide strips would also be feasible, likewise ceramic cutting inserts and guide strips.
  • hard metals consist of metallic hard materials which can be described as relatively brittle because of their high hardness and binders or binder metals predominantly from the iron group (iron, cobalt, zinc) which are relatively soft and tough and are sintered together with the hard materials. Mixtures of ceramics and metals (cermets) are also included among the hard metals.
  • the high hardness and therefore wear resistance of the metallic hard material is combined with the toughness of a binder metal.
  • the desired properties of the drill shank can be adjusted exactly according to the mixing ratio.
  • cubic boron nitride, corundum, sialone or other non-metallic materials are suitable as coating materials.
  • the drilling tool can be used in a universal spectrum of materials for processing, whether this be rock, metal, CFK etc.
  • Heat-treatable steel has proved to be an advantageous material for the cutter carrier, especially with regard to toughness and torsional resistance i.e. the transferable torque. It would also be feasible to use a cutter carrier equipped with replaceable cutting plates, which is itself made of HSS or hard metal.
  • the cutter carrier is a drill head joined to the drill shank in a material-closing fashion, for example, brazed on the drill shaft.
  • the drill head which is subject to higher loading can then be made of a more expensive material and can have a geometry which is more expensive to produce, especially the internal cooling channel(s) whereas the drill shank which is subject to lower loading is made of a cheaper material which is easier to machine and receives its simpler geometry in its own production method.
  • the internal cooling channel has, for example, one or two circular cross-sections at the drill tip whereas a circular through hole is inserted on the drill shank.
  • the drill shank consists of a formed tube of heat-treatable steel.
  • the straight-running machined groove can be impressed into the tube in an easily managed and fast pressing or rolling processing step wherein favourable forming for the internal cooling channel can be achieved at the same time.

  • FIGS. 1 and 2 show a single-lipped embodiment of the deep hole drill according to the invention.
  • the reference number 1 designates a drill head which is soldered onto a drill shank 15 which in turn is soldered into a clamping sleeve 16 .
  • the machined groove is substantially v-shaped where the angle spanned by the machined and unmachined surface is approximately 90°.
  • the drill head At its tip, on the machined surface of the machined groove 13 the drill head has a recess which with its rear surface 5 and the two side surfaces 10 , 14 forms a seat for a replaceable cutting plate 2 .
  • a central threaded hole 7 is drilled into the rear surface 5 which receives a screw 6 guided through a through hole in the replaceable cutting plate 2 .
  • each recesses for guide strips 3 is provided over the circumference of the drill, which abut against a stop surface 9 with their radially-pointing plane counter-stop surfaces 109 .
  • Each surface 9 has a central threaded hole for screwing the guide strips 3 .
  • the replaceable cutting plate 2 has a through hole 8 which, when inserted, is in alignment with a corresponding threaded hole 7 with a minimal offset so that the replaceable cutting plate 2 and also the guide strips 3 can each be screwed rapidly using a single screw 6 .
  • the fixed stop for the guide strips consists in each case of the rear surface 9 of the guide strip seat on the drill head whereas the width of the guide strips is the same for all nominal diameters.
  • the guide strips of the kits for different nominal diameters thus differ only in respect of their radial thickness, i.e., the distance between the outer circumferential surface and the counter-stop surface 109 which is defined by the respective nominal diameter of the tool.
  • FIG. 4 shows an enlarged plan view of the inserted replaceable plate 2 .
  • the through hole 8 shown by a solid line
  • the threaded hole 7 shown by a dashed line
  • the plate 2 impacts against a point located on the second stop side surface 14 of the cutting plate seat and its position is thus determined by the surfaces 5 , 10 , 14 in all three coordinate directions.
  • the two stop side surfaces 10 , 14 are inclined at an angle ⁇ of 80° with respect to one another whereas the two counter-stop surfaces 110 , 114 span an angle ⁇ of 90°.
  • the cutting plate 2 preferably abuts against the stop surface 10 with the entire counter-stop side 110 .
  • a linear stop would also be feasible, as is shown by an inclined stop surface 10 ′ with a dashed line. The angular shaping of the stop ensures that inadequate abutment of the replaceable cutting plate 2 on the cutter carrier (the drill head 1 ) does not occur as a result of tolerance deviations.
  • FIG. 5 shows a modification where linear contact of the cutting plate 2 on the stop 10 is achieved by the base surface 5 of the cutting plate seat and the stop surface 10 spanning an angle smaller than 90° whereas the back of the cutting plate 2 and the counter-stop surface 110 are at an angle of 90° with respect to one another.
  • the embodiment of the deep hole drilling tool according to the invention shown in FIG. 1 comprises a single-lipped deep hole drill with a cutter on the replaceable plate 2 which is supported by means of two guide strips 3 over its diameter in the hole.
  • this embodiment is compared with a further embodiment which has only one guide strip 30 . It is found that the invention can be realized in the same way using this type of deep hole drill. In this case, the additional advantage arises that more space is available for the internal cooling channel (see outlet openings 12 , 11 ).
  • FIG. 7 shows five kits, each comprising a replaceable cutting plate and two guide strips for equipping the drill shown in FIG. 1 .
  • kits cover five nominal diameters ND 1 to ND 5 which lie in a nominal diameter range ⁇ ND (see FIG. 6 ).
  • the through hole 8 , the counter-stop surfaces 110 , 114 and the minor cutting edge 120 are only designated on the replaceable cutting plate for the largest nominal diameter ND 1 and on a relevant guide strip, the counter-stop surface 109 and the supporting surface 50 .
  • the hatched area shows the nominal diameter range AND in which the universally fitting drill head of the deep hole drill from FIG. 1 can be adjusted to the five nominal diameters ND 1 to ND 5 by replacing the cutting plates and guide strips.
  • the through hole 8 on all cutting plates has the same distance c from the counter-stop surface 114 and b from the counter-stop surface 110 .
  • the distance of the through hole from the minor cutting edge which determines the hole diameter increases on the other hand from the value a 0 at the nominal diameter ND 5 and specifically from ND 5 to ND 4 by the value ⁇ a. It can be seen that the radial thickness of the guide strip, i.e. the length of the through hole (shown dashed) increases accordingly.
