Frequently Asked Questions

Common questions about our CNC turning services

What tolerances can you achieve with CNC turning?

Our standard CNC turning tolerance is ±0.005″ (±0.127mm). For precision applications, we can achieve tolerances as tight as ±0.0002″ (±0.005mm) depending on part geometry, material, and specific requirements. Surface finishes of 32 Ra (0.8μm) or better are routinely achieved.

What materials can be CNC turned?

We machine a wide range of materials including aluminum alloys, stainless steel, carbon steel, brass, copper, titanium, tool steel, and engineering plastics like PEEK, Delrin, and Nylon. Each material is optimized for specific turning parameters to ensure optimal surface finish and dimensional accuracy.

What is your quality assurance process?

We maintain ISO 9001:2015 certification with comprehensive quality control including first article inspection, 100% dimensional verification, material certifications, and CMM inspection capabilities. All parts are inspected to drawing specifications before shipment.

What are your typical lead times?

Lead times vary based on part complexity, quantity, and material availability. Simple turned parts typically require 5-10 business days, while complex multi-operation parts may require 10-15 business days. We provide accurate delivery schedules with every quotation.

Do you provide design for manufacturability review?

Yes, our experienced engineers provide comprehensive DFM analysis to optimize your designs for CNC turning. We review tolerances, surface finishes, material selection, and geometric features to ensure cost-effective manufacturing while maintaining design intent.

What file formats do you accept?

We accept all major CAD file formats including STEP, IGES, SolidWorks, AutoCAD, Inventor, and PDF technical drawings. For best results, provide 3D models with complete dimensions, tolerances, and material specifications.
