7. What steps should I take if a dispute arises with my CNC mill supplier?
   In case of a dispute, begin by reviewing the contract terms to understand your rights and obligations. Communicate directly with the supplier to seek a resolution, documenting all correspondence. If informal discussions do not resolve the issue, consider mediation or arbitration, as stipulated in your contract. Always ensure that your agreements include clear dispute resolution processes to facilitate an efficient resolution.

8. Are there specific considerations for international buyers regarding warranty and after-sales support for CNC mills?
   International buyers should ensure that the warranty terms are clearly defined, including duration and coverage specifics. Confirm whether the supplier provides local support or if service must be handled remotely. Understand the process for obtaining replacement parts or service, especially if the machine requires repairs. Additionally, inquire about training for your staff to maximize the machine’s capabilities and ensure efficient operation from the start.
