Frequently Asked Questions
Q: What is the difference between Swiss-type and conventional CNC turning?
A: Swiss-type lathes guide material through a bushing near the cutting tools, providing exceptional support for long, slender parts and enabling complex secondary operations in a single setup. Conventional lathes are typically more cost-effective for shorter parts with simpler geometries.
Q: Can you hold both metric and imperial tolerances?
A: Yes, our equipment and inspection tools are capable of working in both measurement systems. We regularly produce parts to ISO (metric) and ASME (imperial) standards.
Q: Do you provide material certifications?
A: Yes, we provide full traceability with mill test certificates for all metal materials. Additional testing (chemical analysis, mechanical properties) is available upon request.
Q: What is your minimum order quantity?
A: We accommodate orders from single prototypes to high-volume production. For standard materials and processes, our minimum production order is typically 50 pieces, but we evaluate all requests individually.
Q: How do you handle design changes during production?
A: All design changes follow a formal Engineering Change Order (ECO) process with customer approval. We maintain revision control of all drawings and specifications.
Q: Can you reverse engineer parts from samples?
A: Yes, we offer reverse engineering services using CMM measurement and 3D scanning to create manufacturing drawings from physical samples.
