Definitions
- the present invention relates to a countersink tool according to the preamble of claim 1.
- FR-A-2 013 231 is a combined drilling and milling tool according to the preamble of claim 1.
- WO 98/57771 A describes a drilling tool for cutting a round hole, with a cylindrical tool neck of non-metallic Material.
- the drilling tool consists of a cylindrical tube, which front with a cutting surface or The like is provided.
- the plastic adapter serves practically as a coupling between the work spindle and the abrasive coating and consumes the occurring vibration excitations, so to speak within of its own volume, as it is compared to the other at the Oscillation movement involved machine and tool components is relatively flexible. Nevertheless, that will be Plastic spacer at best in the elastic range deform, since it consists of a pressure-resistant plastic, which always withstands the feed forces.
- suitable Plastic can be considered Bakelite, for example.
- materials such as rubber, polyamide, PTFE (polytetrafluoroethylene) are and others conceivable.
- a basic principle of the invention is based on Considering that by the internal damping of the plastic the machine tool, in particular the spindle carrier and the tool spindle is significantly less bending under the present feed forces, since a part of the respective Feed of elastic deformation of the plastic intermediate piece recorded and consumed there.
- the Plastic adapter should be used in industrial Range of channels interspersed to be communicating Flow connection between a usually axial Produce inflow channel and the abrasive coating.
- the invention avoids, among other things, a floating of the diamond coating, which comes about during processing, that small and smallest chips of glass removal add to the coating. These chips practically fill the spaces between the chips Diamonds off and stick to the surface of the tool, so that the diamond tips practically no longer in the production the reduction can be involved. This condition will Usually not detected by the machine tools, so that the feed drive despite reduced grinding ability of Abrasive lining continues to run.
- the resulting high pressures can in conjunction with the elasticity not designed for this type of operation the machines trigger the feared vibrations.
- the abrasive coating can be added between the spaces do not free the grinding diamond on its own, so that this operating condition is extremely unpleasant.
- the plastic adapter gives according to its pressure-elastic properties and thus enables the release of the removal.
- the invention also takes into account the Course of the diamond sharpness over the life of the tool.
- Another advantage of the invention is the adaptability to different head angle of the countersink tool. This is understood to mean the cone angle with which the Tool head faces the workpiece and its apex lies on the geometric axis of rotation of the countersink tool.
- This head angle can be in the range between 0 ° and 180 ° lie and thus an almost arbitrary value within this Take limits. In such countersinking tools separates However, a head angle of 0 ° as well as a head angle of 180 °.
- the head angle is in the range between about 30 ° to about 130 °, preferably at about 120 °, provided that subsidence manufacture for the above-mentioned fastening systems want.
- a preferred embodiment differentiates the invention in two embodiments.
- the plastic spacer forms the tool head and sits centered on the front End of the tool neck.
- This embodiment provides the advantage that the tool head, which a relatively large distance to the tool spindle takes, consists of the lightweight plastic material and thus the countersink tool only to small vibration amplitudes stimulates.
- the invention can also be used on a combination tool, in which in front of the counterbore a drill section is provided for the preparation of the cylindrical bore in Workpiece. Immediately thereafter sets without tool change the Countersink part on the workpiece to the intended depth reduction manufacture.
- This bowl-shaped body can be made by a sintering process be prepared.
- the figures show a countersinking tool 1 for the production of conical recesses 13 on cylindrical bores 12 in Glass panes 10.
- a glass sheet 10 is located on a below of the countersink tool 1 located support 11 and is held there properly while the countersink tool 1 rotating about the (here) vertical axis of rotation the glass sheet 10 is lowered.
- a portion of the bore 12 remains straight cylindrical, while the reduction 13 executed as so-called depth reduction becomes. These are to be understood as subsidence, their insertion depth in the glass sheet 10 is significantly larger than it alone necessary for a deburring of the cylindrical bore 12 would.
- Such countersinking tool has a tool neck 6, the end in the tool holder of a drive spindle a machine tool 4 is clamped against rotation. On the Drive motor 3, the work spindle 2 is rotated. This rotational movement is optionally via a suitable Coupling end as a rotary motion in the tool neck 6 introduced there, where the drive end 5 is marked.
- the tool neck 6 has a tool head 7, which is equipped with a conical head angle 8 is.
- the tool head 7 has a conical inclined surface, where the abrasive pad 9 is attached. through This abrasive pad 9 is at a corresponding feed of the Countersink tool 1 in the direction of the glass pane 10, the depth reduction 13 central and concentric with the straight cylindrical Bore 12 introduced from one side.
- coolant supply 26 is effected by a Axial channel, which the tool neck 6 to the tool head. 7 interspersed and there in a channel system 16a, b, c, d passes, which opens in the region of the abrasive pad 9 on the tool head.
- the axial inflow passage 17 passes through the tool neck central to the axis of rotation, so that the coolant supply 26 is constantly communicating with the abrasive coating.
- the plastic spacer 14 follows in principle the head shape, which is defined by the apex 15 and has corresponding rotary drivers over which it rotatably connected to the drive spindle 2 is connected.
- a peripheral screw 27 in the embodiments according to. Fig.1, 3 and 5, by means of which the plastic intermediate piece 14 on the head side is posted on the tool neck 6.
- the circumferential screw connection 27 sits with a thread in a corresponding Tapped hole of the plastic spacer 14 and engages with a tapered pointed screw head corresponding recesses at the lower end of the tool neck 6 positively, so that the drive torque of the drive motor 3 directly into the plastic spacer 14th can be initiated.
- the rotary driver realized by a possible circumferential adhesive joint 28, between the plastic spacer 14 and the Pads of the tool neck is formed.
- the plastic spacer 14 therefore forms a rotationally symmetrical solid component, which is abrasive coating side the conical head shape of the countersink tool and which Tool side of the associated rotationally symmetric Training the straight-cylindrical tool neck follows.
- the material accumulation of the plastic intermediate piece 14 for the consumption of periodically recurring Forces and moments are used, which may be by the natural vibration behavior of the entire arrangement between Adjust machine tool 4 and workpiece 10.
- the plastic spacer 14 with respect the force acting in the direction of the cone tip 15 feed forces pressure resistant and also has good internal damping properties on.
- At least the plastic spacer 14 is such pressure resistant, that under the given feed forces during manufacture the depth reduction of the abrasive coating 9 substantially only subjected to compressive forces and therefore no elastic Deformations of the plastic spacer in the active area Must follow grinding zone.
- the figures show plastic spacers 14, which are interspersed by channels 10 and 16a to d. This is necessary if you want a communicating flow connection between the abrasive coating 9 and the axial inflow channel 26 create the active grinding zone always and continuously to supply with cooling liquid.
- the axial opens Inflow channel 14 additionally in a central distribution space 18, from which the radial channels 16a start up to 16d into the corresponding outlet openings in the Continue with abrasive coating 9.
- FIG. 2 shows a segmentation of the abrasive coating 9 in (here) four equally sized ring segments, which from respective recess grooves 19 are interrupted.
- the recessed grooves 19 open the respective radial Channels 16a to d, so that the cooling liquid of the head shape following the plastic spacer 14 over the entire can distribute active grinding zone.
- recessed grooves 19 are in the direction of the countersinking tool 1 limited by the material of the plastic spacer and through the adjacent walls of each the conical head of the plastic spacer 14 applied and mutually adjacent ring segments of Abrasive coating 9.
- the figures show countersink tools with head angles, which are smaller than 180 ° and larger than 0 °.
- the head angle is approximately 90 °.
- head angle 8 which clearly has no face plates with a Angle of 180 ° and no straight-cylindrical discs are at an angle of 0 °.
- FIG. 1 shows an exemplary embodiment which the plastic spacer 14 the tool head. 7 forms and centered on the front end of the tool neck. 6 is scheduled.
- the centering consists of a pairing of central Projection 20 and associated central recess 21st on the tool head or tool neck. It is the Depth 23 of the projection 20 is less than the depth 24 of the recess 21, so that the central distribution chamber 18 also at completely deep set intermediate piece 14 is formed automatically.
- the related distribution channels 16a to 16d can consequently mounted alone in the plastic spacer 14 be because the immersion depth 22 between projection 20 and recess 21 is less than the available depth 24 of the recess 21st
- the immersion depth 22 of the projection 20 is in the recess 21 is limited by a depth stop so that the central distribution space 18 is created, which on both sides of the abrasive pad 9 as well as on the side of the tool neck 6 communicates with a channel system for cooling fluid.
- the depth stop is by a Ring paragraph formed on the tool neck 6, against which the annular end face of the plastic intermediate piece 14 under Tightening of the compression fitting 27 held pressure-resistant.
- the channel system 16a to 16d on the side of the abrasive coating 9 in at least two to lead to different radii. This requirement is made possible by the basically conical tool head. All distribution channels 16a to 16d should be in the range the recessed grooves 19 on the top surface of the plastic spacer 14 lead.
- FIGS. 3 and 4 show a development, in which both the plastic spacer 14 as also the tool neck 6 made of plastic.
- Fig.3 consists of Tool neck 6 made of a plastic other than the plastic adapter 14.
- the attachment between plastic spacer 14 and tool neck 6 corresponds to the construction according to Fig.1.
- plastic spacer 14 the entire countersink tool one-piece and one-piece made of plastic and can therefore be referred to as plastic spacer 14 become.
- FIG. 5 shows an exemplary embodiment, in which the tool neck 6, the entire plastic spacer 14 in the direction of the apex 15 interspersed and this towered over a piece.
- the tool neck 6 forms a straight ring cylinder, which at the end face an abrasive Covering z. B. is sintered. Do you do that? Tool towards a glass plate 10, so will first once the straight cylindrical hole drilled, which subsequently from the subordinate countersink tool with the countersink is provided.
- the coating on the Glued on plastic spacer In all embodiments, the coating on the Glued on plastic spacer. To this end Two-component or hot-melt adhesives could be used.
