Oscillating Tangential Cutter EOT-3 (EOT-2) from CNC STEP USA

EOT-3 - Oscillating Tangential Knife for cutting cardboard, veneer, textile, rubber, felt, leather and much more

This cutting knife with an oscillating knife motion is very easy to implement on our CNC machines. But you can use it with most other machines as well as long as you can control a 4th axis (the rotating EOT-3).

EOT-3 will tun in the direction of the cut for precise and efficient cutting of a very wide range of materials. The build quality is excellent and a number of improvements have been made to this latest model E0T-3 compared to the former model EOT-2.

When using third-party machines, it may be necessary to change the pin assignment, but that is usually quite easy to do thanks to the documentation provided for EOT-3.

The knife works really well with sealing materials, leather, cardboard, cork, foams, veneer, rubber, and much more.

EOT-3 General construction

  • Robust solid metal housing for optimum vibration damping
  • Precision ground kinematics for lasting precision.
  • Multiple ball bearings on drive motor
  • Optoelectronic, non-contact and wear-free detection of the blade´s reference position
  • 43 mm neck for attachment to holder.

EOT-3 Technical specifications

  • Supply voltage Control electronics: 12V =
  • Voltage oscillation motor: 12 - 24V =
  • Oscillation: ~ 3500-7000 strokes / minute (Depending on the stroke - 1.0 / 2.0 / 3.0 / 4.0 / 5.0 mm)
  • Measurements: ~ 86 x 58 x 220 mm
  • Oscillation stroke distance can be changed easily by switching one single component
