Temperature is deceptive. And it deceives you at exactly the moment you measure the part.
In this video, White Metal Mancais explains why the heat generated during machining causes metal to expand, why cold temperatures cause it to contract, and why ISO 1 established 20 °C as the worldwide reference temperature for dimensional measurements.
⚙️ In this video, you’ll learn:
How machining heat affects the final dimensions of a bearing
Why cold temperatures can also lead to inaccurate measurements—and often go unnoticed
What ISO 1 establishes and why 20 °C is the reference temperature
What thermal stabilization is and why it must take place before inspection
How incorrect clearance can lead to machine downtime months later
