Semi-automatic cut off machine

The task

Cutting multiple cast components from their runners and risers.

The problem

One of the traditional methods for cutting off cast components is to use an abrasive cutting disc mounted in a circular saw bench. In a typical day at one foundry the operator of such a machine could spend up to 3 hours exposed to vibration magnitudes of up to 5 m/s2. The operation is also very noisy and there is potential risk of injury from contact with the exposed cutting disc.

The solution

Two fully-enclosed, semi-automatic cut-off machines were bought, principally to improve quality and efficiency. The multiple castings are clamped in rotating fixtures, trunnion mounted, and cut off with an abrasive disc.

The result

  • The operator does not need to touch any vibrating components.
  • The operator controls the position and alignment of the castings and cutting discs at a distance.
  • Manual handling of the components and exposure to noise, dust and sparks is reduced.
  • The cycle time is cut.
  • Less metal has to be ground off afterwards, which also saves time in the fettling shop.
  • The risk of injury from contact with the cutting wheel is eliminated.
