6 Steps to Improve CNC Parts Precision: Ensuring Accuracy, Quality, and Reliability

Optimization Design

Reasonable design, reducing internal complexity of the structure, optimizing programming tool paths data, reducing internal stress generated during machining that leads to product deformation and decreased precision of parts.

Material Treatment

Performing heat treatment on materials to change their strength and reduce internal stress, optimizing machining processes, analyzing and resolving machining defects.

Equipment Improvement

Upgrading to 5-axis equipment or using 3-axis equipment with appropriate fixtures to improve CNC machining speed and precision.

Customized Tooling

Designing specialized fixtures and tooling to ensure machining accuracy and stability of dimensions in mass production, while also improving machining speed.

Tool Selection

Selecting high-quality tools and using them professionally is crucial for improving machining accuracy and dimensional stability.

Regular Maintenance

Performing regular maintenance and upkeep on machinery, checking the equipment’s flatness, spindle runout, and regularly monitoring machining accuracy.
