Why is 100% control essential?
Bar turning and quality
The importance of ISO 9001 certification
Our control process in detail
Three separate checks can therefore be carried out on all bar-turned parts produced:
Through a narrow, rectangular green window, we check the presence of the thread over the entire height of the self-tapping insert, by measuring several threads at the end of tapping. The tap entry is opposite this control.
A central square window ensures that no foreign matter (debris, swarf, etc.) obstructs the tapped hole.
These checks ensure that our customers are able to assemble their own production (Mercedes, Scania, etc.) on automated assembly lines.
What happens if a default is identified?
Approximately 10% of production is rejected following this optical inspection. These parts are then manually re-checked by an operator.
Chip clogging can often be eliminated, reducing waste and optimizing production.
Complementary control systems
To ensure 100% production control, Massard et Cie combines several complementary control methods.
Optical sorting machines
Automatic measurement acquisition for SPC
Throughout production, automatic readings of the main ribs are sent to the SPC control cards to anticipate deviations caused by tool wear.
