Why Is ±0.02 mm the Golden Standard for Industrial CNC Parts?

When customers inquire about CNC machining, one of the first questions is often:

"Can you achieve a tolerance of ±0.005 mm?"

The answer may be yes from a technical perspective. However, for most industrial parts, such a tight tolerance is not always necessary.

At Lianyang Metal, we have found through years of manufacturing experience that ±0.02 mm offers the best balance between machining quality and production cost for the majority of industrial components.

For nearly 90% of industrial parts, this tolerance is sufficient to ensure reliable assembly, stable interchangeability, and consistent product performance.

Reducing the tolerance from ±0.02 mm to ±0.005 mm usually means a significant increase in machining time and production cost. It can also lead to a higher scrap rate during manufacturing.

Instead of pursuing unnecessary precision, we focus on providing the level of accuracy that customers truly need.

Maintaining a machining tolerance of ±0.02 mm allows components to fit correctly during assembly while avoiding the additional costs associated with extreme precision.

This is why we regard ±0.02 mm as the "golden standard" for industrial machining.

To maintain this standard, our equipment and technicians are calibrated and maintained every day. Stable processes and consistent quality are the foundation of our production.

At Lianyang Metal, we believe that manufacturing is not about chasing the smallest possible number. It is about choosing the right level of precision for the application.

Choosing Lianyang Metal means choosing smart manufacturing, not unnecessary manufacturing costs.
