- the present invention relates to a method for Production of abrasive tools according to the preamble of the claim 1.
- An example of such a procedure is known from US-A-5 832 360.
- This method is especially suitable for flat and slightly curved Surfaces. Furthermore, for different sizes of corresponding templates are used for the area to be occupied, which complicates the process.
- This method is also primarily for covering flat support surfaces suitable.
- a method is known in which First, a photosensitive electroplating protective coating on the substrate is applied. Thereafter, this protective varnish is replaced by a mask containing the Contains structure of the later particle coating, through-exposed and dried. The unexposed areas are washed out and it remains a structured electroplating protective varnish will adhere to the substrate that supports the Function of a template takes over. Subsequently, on the carrier Particles are electrodeposited and finally the galvanic protective lacquer chemically removed.
- the object of the present invention is now a method to create with which hard material particles on a support with a defined Distribution can be applied, this being simple and inexpensive to be possible, and wherein the carrier is a virtually arbitrary Form may have.
- An advantageous embodiment of the method is that the size of the droplets by changing the diameter of the outlet nozzle can be adjusted, whereby the size of the droplets to the Grain size of the hard particles can be adjusted, but also it is made possible that several grains can adhere per droplet and form a so-called grain cluster.
- the frequency of ejecting the adhesive droplets so that the spacing of the individual adhesive droplets from each other can be preset.
- the scattering of the provided with adhesive droplets carrier with The hard material particles can be carried out with a vibrating table, the spreading but can also be performed by an electrostatic scattering system be in which the hard particles scattered against gravity become. These are aligned in their longitudinal axis.
- an adhesive which hardens can be. This ensures that the hard particles in optimal Way and in a short time firmly connected to the carrier.
- An advantageous embodiment of the invention is that on the with the adhesive droplets and the adhering hard particles Provided carrier an additional adhesive layer is applied. Thereby an optimal connection between carrier and hard material particles is obtained.
- the compound of the hard material particles with soldered to the wearer if the material condition allows.
- This can be done by the carrier before applying the Adhesive droplets are coated with a solder paste, which then dry is left, but the solder paste can also after applying the Adhesive droplets and the sprinkling of the hard particles and the Curing the adhesive applied and dried, causing is achieved for example by spraying.
- the so treated Carrier pushed into a high vacuum oven, where the soldering is performed. This gives an optimal connection between hard particles and Carrier, which also ensures a large grain supernatant.
- a carrier 1 can be seen, which is formed as a sleeve blank is and from which a grinding tool is created.
- This sleeve blank 1 is in known, not shown manner clamped in a machine, which allows this sleeve blank with constant, adjustable rotation speed rotates.
- a Mikrodosiersystem 2 is attached.
- This micro-dosing system 2 allows an adhesive from a Container 3 is conveyed in a nozzle head 4, which drops the adhesive dropletwise from an outlet nozzle 5 outputs.
- Such microdosing are known and usually work with a piezoelectric head, with which the droplets are ejected.
- microdosing allow the ejection of drops of glue, depending on the diameter the nozzle has a diameter in the range of 30 microns to 100 Micrometer can have.
- the ejection frequency of droplets from this Microdosing system is a maximum of 2000 droplets per second. This frequency is adjustable, usually with a frequency of about 500 to Worked 1000 droplets per second.
- This microdosing 2 is so on the machine, not shown arranged that the outlet nozzle 5 in the direction of the axis of rotation of the sleeve blank. At the same time, this outlet nozzle also in the other two perpendicular directions traversable.
- the micro-dosing system 2 For applying the adhesive droplets 6 of the sleeve blank 1 in Rotation offset, the micro-dosing system 2 is adjusted so that the distance the outlet nozzle 5 from the tube blank 1 is about 0.5 mm, the microdosing 2 is moved along the axis of rotation of the sleeve blank 1, during which the glue drops are dispensed. This will be these drops of glue with a constant distance from each other on the surface the sleeve blank 1 applied. With appropriate monitoring equipment The output can be controlled by adhesive droplets, so this only takes place when the tube blank 1 is located below the outlet nozzle 5.
- the feed rate of the microdosing 2 and the frequency the droplet output can be the glue points in different ways Apply structures to the support 1, in the present case as a sleeve blank is trained.
- the hard material particles for example by means of a Vibrating table, not shown, scattered. These hard particles can be used for Example CBN or diamond.
- the grain diameter of these hard particles ranges between 40 microns and 1000 microns. Depending on size the grain and the glue dot diameter remain one or more Stick grains at an adhesive point. The not on a glue point 6 impinging hard particles bounce on the surface of the tube blank. 1 down and fall down.
- a solder paste On the tube blank 1 with the attached hard particles is applied a solder paste. This is done here in a known manner with an airbrush gun
- the sleeve blank thus provided with the solder paste can at the Air or be dried with a hot air dryer. Then he arrives Tube blank in a high vacuum oven, in which at a temperature from about 720 ° C to 1000 ° C the soldering takes place, causing the hard particles be firmly connected to the sleeve blank.
- an adhesive was used which hardens under the influence of UV light. It would also be conceivable to use a Adhesive that is infrared curing. Optionally, there is also an adhesive suitable, which issaushartend. In addition, the glue, if a soldering takes place, also suitable for vacuum.
- an electrostatic Spreader 7 be used Here are the hard particles on a Conveyor belt 8 under the action of an electric field between Conveyor belt 8 and sleeve blank is produced in a known manner, against the Gravity scattered, the hard particles, with one on the sleeve blank 1 applied adhesive droplets come into contact 6, stick, the others fall behind. With this type of scattering the hard particles are aligned in their longitudinal axis and remain so adhere, the grain supernatant will be improved. Of course, other methods for scattering the particles on the carrier or the adhesive droplets conceivable.
- Fig 3 such as a flank surface of a Peripheral grinding wheel treated according to the inventive method can be.
- the axis about which the clamped carrier 1 rotates, is rotated by 90 ° compared to the previously described examples.
- the outlet nozzle 5 of the microdosing system 2 is the width of the flank surface moved towards and away from the axis of rotation. This will be the adhesive droplets 6 practically on a zigzag line on this flank surface applied, this is then as previously described with hard particles sprinkled and treated accordingly.
- the peripheral surface of the peripheral grinding wheel is treated.
- the microdosing system 2 leads a reciprocating motion that is aligned parallel to the axis of rotation is, wherein the travel of the width of the resulting peripheral grinding wheel corresponds
- the adhesive droplets 6 below sprinkled with hard particles the treatment takes place, as in the first Embodiment.
- the structuring is also possible with the latter two examples the applied adhesive droplets 6 by changing the rotational speed, the reciprocation of the microdosing system 2 and the frequency of the dispensing of the adhesive droplets.
- the Kornuberstand a with the inventive method very large, the distance b of the hard grains 8 from each other is larger and substantially constant.
- the carrier 1, which treated according to the inventive method becomes, have the form of a rotation body.
- the to be treated Surface can have any shape, it can also be flat.
- the carrier may be made of any material, such as metal or ceramics.
- the method according to the invention can also be used Producing abrasive belts, wherein the carrier be any solid material can, such as paper, textile fabric or films of metal, ceramics or plastic.
- the hard particles applied to the carrier can also consist of a virtually arbitrary material, such as diamond, CBN, any kind of ceramics, tungsten carbide, titanium carbide or carbide and their mixtures.
- the particle sizes of the hard particles used depend on the Type of application of the abrasive tool produced from the diameter of this For example, grains are in the range of 2 microns to 2 millimeters. It is also conceivable that depend more adhesive particles per adhesive droplets remain, whereby a so-called grain cluster are formed. Thereby a particularly good attitude is achieved, since the individual grains during the labor input can repell each other.
- soldering process to which the particulate carrier is exposed can, as described, carried out in a high vacuum oven Of course, this can also be done by soldering, brazing or Soldering under inert gas done.
- the properties of the adhesive used are those used Materials of the carrier and the particles adapted. For some use cases no additional attachment of the particles to the carrier is required, for certain materials, applying an additional, curable adhesive layer, with some materials and certain Applications, a soldering treatment is appropriate.
