The deburring system for your requirements:
thorough • quick • economical

The deburring of workpieces is becoming increasingly important. In recent years, the performance of chip-producing processes has increased significantly. At the same time, however, deburring has commonly been done using the same methods as have been used for decades, despite the fact that the deburring working process places particularly high demands on quality and process reliability in order to be able to manufacture cost-effectively and with high quality standards in the modern highly organised manufacturing structures and for ever more complex workpieces. Here, the PINFLOW procedure offers an innovative alternative to other procedures.

The PINFLOW principle

The workpieces which need to be deburred are placed in a piece-specific device which is found on the work surface in the machine‘s processing area. The work surface, together with the device and the workpieces, is vibrated horizontally using vibrators. The device, acting as a con­tainer, is filled with the deburring medium. The vibration creates relative motion between the workpieces and the deburring medium. The deburring medium usually consists of small steel balls which, during the machining process, work not only externally but also penetrate into the piece and thus produce a deburring effect even on difficult-to-access surfaces.

The areas of application

The PINFLOW system can be used everywhere where, for example, simple and complex workpieces need to be internally and externally deburred, where moulding sand residue needs to be removed or where the surface needs to be smoothed:

  • Deburring complex components such as hydraulic blocks, pump housings, cylinder heads, etc.
  • Removing the cast skin from cast iron workpieces
  • Removing moulding sand and core sand residues
  • Smoothing and polishing
  • Compressing surfaces
  • Rounding off sharp edges
  • Removing sooty carbon residues
  • Machining steel, grey cast iron, aluminium, brass, bronze
