Frequently Asked Questions
Q: What factors should I consider when selecting the right machine?
A: When choosing a machine, first match the worktable travel and cutting capacity to the size and thickness of your workpiece to identify a suitable model. Additionally, verify whether the precision and surface finish meet your standards.
Q: The standard voltage in our country is three-phase 220V (or single-phase 220V, etc.), but your machine uses three-phase 380V. Is voltage adjustment possible?
A: Absolutely. Just let us know your specific voltage requirements, and we can customize the machine accordingly.
Q: What details do you need from us to prepare a proposal?
A: We'll need the worktable dimensions, required travel range, and any special requirements you may have.
Q: Are you a manufacturer or a trading company?
A: We specialize in manufacturing CNC machine tools and have over 20 years of experience in this industry.
