Questions & Answers

At Witcool, we maintain strict control over every stage of the CNC machining process, ensuring high product quality and precision. We deliver reliable solutions by adhering to standards and implementing innovations to enhance every project.

Why is quality control important in CNC machining?

Quality control ensures that products meet established standards, helps prevent defects, maintains customer satisfaction, and supports the overall reliability of the manufacturing process.

The main parameters include dimensional accuracy, tolerances, surface finish, and material integrity. Adhering to these is essential for the functionality of machined components.

At Witcool, quality inspection includes dimensional measurement, material analysis, and the use of advanced inspection equipment such as CMMs and optical systems to verify compliance with specifications.

Our skilled operators detect subtleties that automated systems might miss, ensuring optimal machine performance and early identification of potential issues.

Witcool prioritizes confidentiality by applying strict protocols, including secure file transfers and non-disclosure agreements (NDAs), to protect your designs.

If a quality issue is identified, we halt production, investigate the root cause, and implement corrective actions to prevent recurrence. Clients are promptly informed of any delays or issues.
