This high RPM capability is vital for achieving the desired surface finish and dimensional accuracy in small parts.

What is the smallest machining tolerance possible?

When it comes to machining small parts, achieving tight tolerances is critical. The smallest machining tolerance possible is often around ±0.001 inches. This level of precision is achieved through advanced techniques and state-of-the-art equipment, such as CNC Swiss machines. These machines are capable of maintaining exact dimensions even when working with complex geometries and challenging materials. This precision is essential in industries where even the slightest deviation can lead to significant issues, such as in medical implants or aerospace components.
