Extruders – Twin Barrel

Aligning extruders can take hours and hours and it is hard to find methods that actually work, especially for twin-barrel extruders that have multiple sections that need alignment where “stack up” errors can lead to big misalignments. Not aligning extruders causes the barrels and screws to wear out much sooner than desired, leading to excessive costs for replacements. There is a much better way.

Our 50 years of alignment experience went into the design of the L-703 Twin-Barrel Extruder Borescope Alignment System that makes checking the alignment of extruder barrel sections to gearboxes much easier and much faster:

  • Aligns extruders up to 70% faster than conventional or optical borescope methods.
  • Setup < 25 minutes.  Data in 5 minutes after that!
  • The A-510 2-Axis Bore target uses self-centering bore adapters that find the bore center without any moving parts.  No 0º and 180º measurements, so it takes just 5- 10 seconds to get a measurement!
  • Customized bore adapters with a large range of barrel IDs from 1.18 to 18 in. (30 to 458 mm).
  • Resolution of .0001 in. (0.001 mm).
  • System accuracy of .001 in. (0.025 mm) in 20 feet (6.1 m).  
  • Self-Centering Chuck fixture to mount the L-700 on the gearbox shafts for ultra-fast setup.
  • Real-time alignment data speeds alignment by showing barrel movements as it’s being  adjusted.
  • Simple, handheld readout show the alignment data in the vertical and horizontal axes.
  • Horizontal and vertical center & angular adjustments allow for easy alignment of the laser to the gearbox spindle’s rotation axis.
  • Battery-operated laser with a range of 100 ft. (30 m).
