Frequently Asked Questions
What is the maximum diameter for CNC turning? Our CNC lathes handle diameters from 1mm to 300mm, with concentricity controlled to ±0.005mm.
What materials can be turned? Aluminum, stainless steel, brass, titanium, carbon and alloy steel — both bar stock and forged blanks.
Do you offer Swiss-type turning? Yes. We operate swiss-type and fixed-head CNC lathes with live tooling for complex mill-turn parts and bar-fed unattended production.
What is the minimum order quantity? We accept from 1 piece for prototyping up to mass production of millions of pieces per month.

Materials We Process
Bars, tubes, castings up to 300mm dia.
Scope of Service
- high-volume turned parts
- precision shafts and bushings
Capability Highlights
Accuracy to ±0.005mm, IT6-IT7 grades, verified on a CMM. Machine park includes 3/4/5-axis machining centers, CNC lathes and Swiss-type machines, with in-house fixture design and CAM simulation for first-pass success.
Quality System
Quality is verified, not assumed. First article inspection is mandatory on every new part number, and our quality engineers record CpK on critical dimensions for volume programs. With a coordinate measuring machine (CMM), surface roughness testers, and a temperature-controlled inspection room, measurement uncertainty is kept far below the tolerances we quote.
Lead Time & Packaging
Quotations with manufacturability feedback are returned within 24 hours of receiving your drawing or 3D model. Prototypes ship in 3-7 days; production orders run 7-15 days depending on quantity and finishing. Export packing uses anti-scratch film, VCI paper, or custom trays so parts arrive ready for your assembly line.
Why Customers Stay
Engineering support is included, not extra. Our CAM engineers review every drawing for manufacturability and cost reduction before quoting, and flag tolerance or finish decisions that materially affect price. Customers typically save 10-25% on program cost after this review.
