Definitions

  • a large number of devices are known for the surface treatment of workpieces which can be embrittled by cold.
  • a conveying device with which the workpieces are conveyed and circulated, a spray device for a low-boiling liquefied gas, usually nitrogen, and at least one centrifugal wheel for an abrasive such as 4 Cast steel or plastic granulate.
  • Rotating drums, drum-like belts or rotating plates are known as conveying means.
  • a device for deburring workpieces is known from German Offenlegungsschrift 26 50 202, in which the workpieces are conveyed on an oscillating trough which is provided with sieves for separating granules, coarse breakage and dust.
  • the invention is therefore based on the object to provide a device for surface treatment of cold-brittle workpieces, which, starting from the known device, enables even sensitive and small filigree molded parts, possibly in small batches, to be processed quickly and gently.
