Definitions

  • the invention relates to a processing device for Use in a device for mechanical surfaces and / or Edge processing of cutting tools, in particular for rounding the cutting edge (s) of cutting inserts or the like, with at least one by one Drive in relative movement to the area to be processed of the cutting tool displaceable and for surface and / or Edge processing with the corresponding Contactable areas of the cutting tool Processing means.
  • the object of the invention is to overcome the aforementioned disadvantages to avoid and to specify a processing device, with the processing of cutting tools with different high areas with good machining results is possible.
  • a processing device for use in a device for mechanical Surface and / or edge processing of cutting tools, especially for rounding the cutting edge (s) of Inserts or the like, with at least one by a drive in relative movement to the one to be machined Area of the cutting tool movable and for Surface and / or edge processing with the corresponding Contactable areas of the cutting tool Machining means, the machining device at least one as an elongated, essentially cylindrical trained and through the with the processing device connected drive in a rotary Movement around a substantially parallel to the longitudinal extent Axis displaceable processing means.
  • This allows editing of the corresponding areas of the cutting tool take place much more precisely, since that Machining means clearly compared to conventional brushes can be made smaller.
  • the processing grinding pen can be designed as a processing grinding pin Processing means are provided, the rubber, silicone or is plastic-bound and has abrasive components.
  • the processing grinding pen can also be in one elongated hollow body adapted to its contour and arranged protruding from the end of the hollow body his. This makes it an easy to manufacture machining tool indicated that a surface processing in allows very small dimensions and on the one hand due to due to its massive shape and on the other hand of the surrounding hollow body very stable and well supported is. Machining pens achieve very good stock removal results and can precisely process a contour be tracked.
  • ⁇ can be used as flexible processing brush threads trained, especially tortuous or intertwined processing means provided be made of plastic or metal and be filled with and / or interspersed with abrasives can.
  • tortuous or intertwined processing means provided be made of plastic or metal and be filled with and / or interspersed with abrasives can.
  • This will give greater flexibility to the Machining means enabled, so that a gentler Editing is possible and due to the flexibility Compensation for unevenness or the like can be done. It can be between the individual Machining brush threads free space with a for example binders made of plastic be filled up, so that a higher stability is given is.
  • the processing brush threads in an elongated, in particular circular cylindrical hollow body provided and arranged protruding from the end of the hollow body so that good lateral guidance is guaranteed is and processing impairment by relocating the Machining brush thread ends or unwanted fanning of the processing brush thread bundle can be avoided.
  • the width and depth or the diameter of the Hollow body be small, in particular about 2 to 20 mm be.
  • a fixing device against displacement of the Machining brush threads against the rotational movement be provided in the hollow body so that the hollow body is driven can be and the processing facility can be constructed more simply.
  • the fixing device can be a clamping device include.
  • the fixing device can also be at least one separating device extending radially in the hollow body, in particular have a partition or the like, so that the movement of the Drive from the hollow body on the processing means is transferable.
  • the processing means can be fed through a feed device, especially during machining operations be trackable, so that a balance of the Wear from processing, either during processing breaks or continuously during processing respectively. If a clamping device as the fixing device is provided, it can be moved in the tracking direction and / or at short notice during the tracking be deactivated.
  • the invention also relates to a device for mechanical Surface and / or edge processing of cutting tools, especially for rounding the cutting edge (s) of cutting inserts or the like.
  • Such devices are in a wide variety of embodiments known. Besides sandblasting and Tumbling a machining with a brush-shaped Machining device most widely used, being such brushes with elastic bristles and consist of a roller rotating about its longitudinal axis.
  • the processing means can preferably be stored in a storage magazine z. B. stored on drums or the like and an output device for the corresponding assembly and feed can be provided, so that a cumbersome and time-consuming changing of the processing means is not necessary when worn.
  • you can also different shapes and Types of machining means can be provided so that an adaptation to different within the device Processing requirements are met can.
  • a shortening or Disconnect as well as processing, e.g. B. stranding or to understand the processing means.
  • a device for intertwining or Interweaving of the processing means with each other be so that through appropriate training (stranding) the machining means a higher stability of the machining means can be done.
  • At least one handling device to change the position of the processing device be provided and / or at least one handling device to change the position of the to be processed Cutting tool may be provided so that a free control for a perfect processing required movements are possible.
  • the handling device either as a robot, in particular be designed with four or five axes, the handling device can also be used as a swivel table or CNC machine.
  • the invention further relates to a method for mechanical Surface and / or edge processing of Cutting tools, in particular for rounding the cutting edge (s) of cutting plates or the like, by means of a processing device that at least one by a drive in relative motion to that to be machined Area of the cutting tool that can be moved and and / or edge processing with the corresponding Areas of the cutting tool that can be brought into contact Has processing means.
  • the object of the invention is therefore also a method to improve mechanical surface treatment that good results even when editing Cutting tools achieved with different high areas become.
  • the processing can in particular by a Processing device or a device of the above Sort of.
  • more than one can be used as the processing means flexible machining brush threads trained, in particular entwined or intertwined processing tools be provided in a preferred embodiment of the invention in an elongated, in particular circular cylindrical hollow body of the processing device can be arranged and the end of the Can protrude hollow body.
  • the processing brush threads can be coordinated the rotational speed is freestanding so far at the end be that by centrifugal force in approximately umbrella-shaped shape for side processing in particular be deflected.
  • the shape of the umbrella-shaped structure can be influenced by the cantilever length and the speed and can therefore also be controlled during targeted operation the processing can be influenced.
  • the Longitudinal extension of the processing brush threads approximately at right angles to the axis of rotation and machining is done with the end point of the processing brush threads.
  • the device 1 shows a device 1 according to the invention for mechanical Surface and / or edge processing of a Cutting insert 2 with partially raised edge areas 3.
  • the device 1 has a processing device 4 on which is an elongated, substantially cylindrical trained machining means 5, which by a drive 6 in a rotary movement to one
  • the longitudinal extent of the processing means 5 essentially parallel axis is displaceable.
  • the processing means 5 can be used as a processing grinding pen be solid, but it can also as shown in FIGS. 2 to 5, of several flexible Machining brush threads 7 exist.
  • the processing brush threads 7 can for example be made of plastic or Made of metal and filled with abrasive materials 8 and / or be enforced (see FIG. 2).
  • the processing brush threads 7 in Depending on the speed of rotation so far that a distraction into an approximately right angle is aligned to the central axis. This can editing either with the side endpoints or through the enlarged face.
