Challenges and solutions

This solution is for your foundry if you face:

Key advantages

  • Easy programming: point-based programming with an interface designed specifically for fettling. Programs are created quickly, intuitively and efficiently.
  • Simple, low-cost fixtures: they work as a cradle for the casting. Easy to build, affordable and practical day to day.
  • Fast setup: changing the fixture and loading a new program takes less than 15 minutes, so automation pays off even for small batches.
  • Pre-machining: thanks to the high precision and consistency of CNC, pre-machining operations can be done on many parts, saving cost and later steps.
  • Laser measurement: the laser system detects dimensional variations in each part and prevents collisions, for a safe and reliable process.
  • High-performance diamond discs: developed for fettling, with strong removal power, exceptional durability and better production performance.

FAQ

Automated casting fettling: frequently asked questions

What is casting fettling and why automate it?

Fettling (also called deburring or grinding) removes the burrs, parting lines and excess material left on a casting when it comes out of the mold. Done by hand it is heavy work, with dust, sparks and vibration, and the result depends on each operator. With a 5-axis CNC machine every part gets the same program: more parts per hour, a uniform finish and less scrap.

What is the difference between a CNC fettling machine and a robotic deburring cell?

Both automate finishing, but the CNC machine is built specifically for fettling: it requires a much smaller investment than a traditional robotic cell, uses simple low-cost fixtures, and point-based programming is done by your own team, with no robotics specialists.

Which parts and materials can be fettled?

Iron, steel, aluminum and other castings. Depending on the model, from parts of 350 × 200 mm and 25 kg (GV 120) up to 1000 × 400 mm and 120 kg including fixture (GV 2100).

Does it pay off for small batches or only for high volume?

It works for low, medium and high volume. Changing the fixture and loading a new program takes less than 15 minutes, so automation pays off even for small batches.

How much does productivity increase?

In a real application output went from 60 to 130 parts per hour with a single operator (+116%) and finishing scrap dropped from 3% to 0%.
