Why Are Tolerance and Dimensional Control Important in Machining?

What Does Tolerance Mean?

Berce Endüstri, standing out among machining companies in the Kocaeli İzmit region, places special importance on tolerance and dimensional control in production. Tolerance defines the allowable deviation from the ideal measurement of a part. These limits play a critical role in assembly compatibility and product performance.

At our production facility in İzmit, each workpiece is machined on CNC machines and measured with micron-level precision. Quality controls conducted using calipers, micrometers, and 3D measuring devices ensure part compatibility. Berce Endüstri does not compromise on tolerance accuracy when it comes to quality machining in Kocaeli.

For example, if a part with a dimension of 50 mm has a tolerance of ±0.02 mm, then the part must measure between 49.98 mm and 50.02 mm. This range guarantees that parts will work together compatibly.

Why Is It Important?

• Ensures Assembly Fit: Perfect joining in systems composed of multiple parts is only possible with appropriate tolerances.

• Increases Performance and Durability: Excessive gaps or tightness between parts increase the risk of vibration, wear, and failure.

• Prevents Process Repetition: Accurate measurement and control reduce production errors, saving time and cost.

• Necessary for Quality Certification: Dimensional control is a critical step in quality systems like ISO 9001.

How Is It Measured?

Precise measurements are made using manual tools such as calipers, micrometers, comparators, as well as 3D measuring devices (CMM). Measurement results are documented to ensure quality tracking.
