Faster cutting

Exotom is ideal for cutting the hardest of materials, faster cutting of standard materials, and very fast cutting of extra-large workpieces. OptiFeed force control enables cutting at the fastest possible speed within set parameters without overloading the workpiece and the cut-off wheel.

Minimum deformation

ExciCut technology ensures minimal contact area between the cut-off wheel and the workpiece, with reduced risk of damage and less work in subsequent preparation processes.

Simple to operate

Two simple keys combined with a large graphic display are incorporated on a swiveling control panel. The multifunction knob enables easy control of all cutting parameters, even when wearing work gloves. The joystick enables fast and precise positioning of the cut-off wheel.


  • Exotom ExciCut

    ExciCut – cutting of the hardest materials

    ExciCut uses an oscillating movement of the cut-off wheel to reduce the contact area between the cut-off wheel and workpiece. This enables cutting of very hard materials in very large sizes, and also the use of harder cut-off wheels, which increases the lifetime of the wheels, thus reducing costs.

  • Exotom Direct Cut

    Direct Cutting

    Direct cutting mode is recommended for softer materials where the cut-off wheel moves down in a linear movement into the workpiece at the preset feed speed.

  • Exotom AxioCut Step

    AxioCut – sectioning of extra-large workpieces

    AxioCut adds 150 mm cutting capacity for extra-large workpieces. The field-upgradable option includes Step cutting for very fast cutting and Sweep cutting for fast cutting, combined with better wheel economy.

  • Exotom OptiFeed


    OptiFeed optimizes the feed speed without sacrificing the quality of the cut or good wheel economy. During cutting, Exotom-150 continuously measures the load on the cutting arm. Once the preset force limit is reached, the feed speed is reduced to avoid damage. The feed rate is increased again once the load on the cutting arm decreases.

    Blocking mode

    Nonessential controls of the operation modes can be partly or fully blocked by using a pass code to avoid operator errors and damage to the machine and samples.

  • Exotom AxioWash


    Struers' patented* automatic chamber cleaning function that can be used every day to keep the machine in optimal working condition. * AxioWash is protected under EP Pat no. 1965947.

  • Exotom AutoStop


    During unattended operation, Exotom-150 automatically detects when the workpiece has been cut through, returning the wheel to its start position and stopping all motors.

  • Exotom QuickPosition


    The QuickPosition function places the cut-off wheel rapidly in contact with the workpiece and retracts it immediately, ready for cutting. It can be used both before and during cutting.
