Definitions

  • the present invention relates to a device for fixing a utility plate and a processing method using the device.
  • shielding hoods for high-frequency circuits can be produced with this device.
  • the workpiece support table consists of vacuum elements, each having a suction channel, wherein below the workpiece, a suction surface is formed, in which the vacuum elements each have an exchangeable wear element for workpiece support, which forms the extension of the suction channel.
  • a disadvantage of the in the DE 195 30 584 C1 described workpiece support table is the direct contact of the workpiece with the workpiece support surface, which limits a vacuum channel.
  • the workpiece support surface can be damaged, with the result that the vacuum no longer exists underneath the damaged workpiece support surface.
  • a faulty vacuum below the damaged workpiece support surface means a worse fixation of the workpiece during the milling, which leads to incorrectly milled workpieces and thus to a higher number of broke pieces.
  • the DE 42 38 299 C1 describes a method for milling a workpiece from a plate-shaped material, wherein the plate-shaped material is preferably held by negative pressure on a clamping surface.
  • a circumferential end milling tool is in a closed edge of the workpiece bordering milling path through the Material led.
  • the milling path ends with an area on the circumference of the workpiece, which the cutting path has previously detected and in which the depth of the milling path initially had a smaller amount than the thickness of the material.
