In the competitive world of global manufacturing, the terms "accuracy" and "repeatability" are more than just technical jargon; they are the cornerstones of quality and the bedrock of trust between a precision machining supplier and its international clients. For businesses seeking a reliable partner for CNCmachined components, a deep understanding of these specifications is crucial for project success.

Accuracy refers to how close a measured value from a CNC machine is to the true or intended value—the target dimension on the engineering drawing. Imagine a skilled archer. Accuracy is their ability to hit the bullseye. If a drawing calls for a diameter of 25.000 mm, a highly accurate machine will produce a part with a diameter extremely close to that value. Accuracy is influenced by factors like machine calibration, thermal compensation, and control system resolution. It defines the capability to produce a single, perfect part.
Repeatability: Hitting the Same Spot, Every Time
Repeatability, often called precision, is the machine's ability to consistently produce the same result across a series of identical parts. Our archer is now firing a volley of arrows. Repeatability is their ability to group all arrows tightly together, even if that grouping is slightly offcenter. A machine with excellent repeatability will produce a batch of 1,000 parts where the 1st and the 1000th part have virtually identical dimensions. This is governed by the machine's mechanical rigidity, backlash in ball screws, and servo motor performance.

The Critical Interplay for Your Business
The ideal scenario is a machine that possesses both high accuracy and high repeatability—hitting the bullseye with every single shot. However, it's possible to have high repeatability with low accuracy (consistent but wrong dimensions) or low repeatability with high accuracy (a perfect part, but only by chance).
For your projects, this distinction is paramount. High repeatability ensures part interchangeability, reduces assembly issues, and guarantees that your product performance remains consistent across large production runs. High accuracy ensures that complex geometries and tighttolerance features are machined correctly the first time, reducing scrap and rework.
Why This Matters for Your Sourcing Decision
Choosing a manufacturing partner like ours, which invests in modern CNC machinery with proven, high specifications for both accuracy and repeatability, directly translates to tangible benefits for your business:
