Frequently asked questions
Find answers about machining services, materials, tolerances, files, inspection, shipping and payment.
What types of machining services do you offer?
We provide four core precision machining services: EDM (Electrical Discharge Machining), CNC Machining Center / CNC Milling, CNC Lathe Turning, and Wire EDM. We custom-make precision mechanical components mainly for aerospace and oil & gas service equipment.
What materials can you process?
We process a wide range of metals including stainless steel, alloy steel, titanium alloy, aluminum alloy, copper, hardened steel and other hard-to-cut materials widely used in aerospace and oilfield industries.
What tolerance can you achieve?
Our machining can achieve tolerances as tight as ±0.005 mm, suitable for aerospace and oilfield service parts with strict precision requirements. The applicable requirements are reviewed against your drawing and project specification.
Do you accept custom parts according to drawings or samples?
Yes. We support custom manufacturing based on your 2D drawings, 3D CAD files such as STEP or IGES, or physical samples. PDF drawings are also accepted. Both prototype and bulk orders are welcome.
What file formats do you accept for quotation and production?
We accept STEP, IGES, STP, SAT, DWG, DXF and PDF. STEP or IGES 3D models are preferred for accurate quotation.
Can you provide inspection reports and material certificates?
Yes. We can offer material test certificates (MTC), dimension inspection reports and other inspection documents as required for aerospace and oil & gas industry compliance.
Do you ship worldwide?
Yes. We support global shipping by air, sea and express (DHL / FedEx / UPS), and we can also work with your freight forwarder.
What is the payment term?
For new customers: 50% deposit before production, balance before shipment. Flexible terms can be discussed for long-term cooperative clients.
