Frequently Asked Questions
- What is a Mill Test Report and why do you provide it? A Mill Test Report (MTR) is a quality document that certifies the chemical composition, mechanical properties, and dimensional accuracy of the machined part. We provide it as standard to guarantee material traceability and compliance with your specifications.
- What is the maximum workpiece size you can handle? Our standard gantry mill can accommodate parts up to 8000×4000×2000 mm (length × width × height). For oversized items, we can discuss custom fixturing or alternative machine access.
- Do you offer secondary services like heat treatment or surface coating? Yes, we can coordinate with our trusted partners for heat treatment, anodizing, painting, and other finishing – all under our quality control.
- How do you ensure the accuracy of large parts? We use a combination of laser calibration, temperature-controlled shop floor, and in-process probing. Final inspection is performed with a coordinate measuring machine (CMM) and documented in the MTR.
- What materials can you machine? We regularly machine carbon steel, alloy steel, stainless steel, aluminum, cast iron, bronze, and engineering plastics. For exotic alloys like Inconel or titanium, we have specialized tooling and cutting parameters.
- What is your typical lead time? Lead time depends on complexity and current workload. Generally, simple parts take 10–15 working days, while complex multi-axis parts require 20–30 working days. Rush orders are available upon request.
- Do you provide samples before mass production? Absolutely. We recommend a first-article inspection (FAI) with a sample part to validate the process. The sample and report are shipped at cost.
- Can you work with proprietary designs or NDAs? Yes, we respect your IP. We gladly sign Non-Disclosure Agreements and securely store your designs. Your data is never shared with third parties.
