Komax Cosmic 927R / 927RX / 927RX-WL

Cosmic 927R / 927RX / 927RX-WL – Rotary wire stripper

  • For processing demanding conductors
  • Smooth cut surface
  • Twisting function
  • Easy to operate
  • Light and portable

The rotating blade heads of the Cosmic 927 series provide the perfect solution for processing demanding insulation.
Each model in the series has a specific area of application: The Cosmic 927R processes a large range of insulation materials. The 927RX shows its true strength with thin or bonded types of insulation. The 927RX-WL accommodates the biggest stripping length.

Area of application

The stripping machines process conductors with outside diameters of 0.25 to 5.3 mm or a cross section of 0.013 to 6 mm² (AWG 36 to 10). The machines can be used for full and partial pull-off on individual conductors or on inner conductors of multi-core cables.
Cosmic 927R: This model has a rotating blade head featuring two blades. It processes a large range of insulation. The Cosmic 927R is especially suited to handling a great diversity of products made in small to medium quantities.

Cosmic 927RX: This model is ideal for processing thin and bonded types of insulation (e.g. thin Teflon insulation). These types of insulation require a high pull-off force. The Cosmic 927RX has a special rotating blade head for this purpose fitted with linearly guided quadruple blades. The quadruple blades centre the cable precisely and transmit the big pull-off forces needed.

927RX-WL: This model is designed for big stripping lengths of up to 100 mm. It is based on the proven principle of the Cosmic 927R.

Rotating stripping

Rotating blades provide major advantages for stripping:

  • The blades cut through the insulation and down to a thin ring around the conductor. That means the remaining area to be pulled off is small and the pull-off force is lower.
  • The cut surface is smooth and free of lines or ridges.
  • The blades displace the insulation uniformly; conductor tips are not bent.
  • The same blade processes the widest variety of insulation and cross sections. Blade changes are eliminated and conversion times are reduced.


  Twisting for better further processing

Splayed conductor ends disrupt further processing. The twisting function in the Cosmic devices prepares the cable in an optimum way for being handled during assembly or tinning.
The strand end can be twisted to the right or left during insulation pull-off. Twisting plates are available as an option for even more intensive twisting.
