Frequently Asked Questions

Q: What is the maximum part size you can accommodate on your CNC lathes?

A: For chucked components, our maximum turning diameter reaches up to Φ 350 mm (13.78 in.). For continuous high-volume bar feeding, we accommodate rod diameters up to Φ 65 mm (2.56 in.) with a maximum turning length of 600 mm (23.62 in.).

Q: What is your minimum order quantity (MOQ) for turning projects?

A: We have no Minimum Order Quantity (MOQ) restrictions. We provide the exact same level of technical support for 1-piece engineering prototypes as we do for automated mass production scaling to 10,000+ units.

Q: What tolerances can you consistently achieve for turned parts?

A: For critical features like bearing seats or press-fit diameters, we confidently hold linear and outer diameter (OD) tolerances down to +/- 0.010 mm (+/- 0.0004 in.) depending on material choices and part geometry.

Q: Can you manufacture based on physical samples without blueprints?

A: Yes. You can ship physical components to our metrology lab. We will perform exact dimensional analysis and reverse-engineer standard CAD files for production.

Q: Do you provide material certifications and inspection reports?

A: Yes, absolutely. Every shipment from SHD includes standard dimensional inspection layouts. Official Material Test Certificates (MTC) and CMM measurement records are provided free of charge upon request.

Q: How do I request a commercial quotation?

A: Simply submit your CAD files, material specifications, and expected quantities through our secure inquiry channel. Our technical engineering desk will deliver a comprehensive commercial quotation and free DFM report within 24 hours.
