Our company specializes in high-accuracy CNC machining solutions designed to meet the needs of global clients. With 20 years of practical experience in metalworking, we deliver consistent quality for parts requiring precision, from prototype units to short production runs. We regularly achieve tolerances of ±0.01mm and work with a wide selection of metals and finishes.
Accuracy: Tolerances up to ±0.01mm
Size Range:
• Width: 1.5mm to 80mm
• Length: Up to 1000mm
Materials: Aluminum, copper, stainless steel, carbon steel, and more
Accepted files: 2D and 3D CAD files (DWG, STEP, PDF, STL)
Machining processes: milling, turning, drilling, tapping, polishing, and trimming
Each order is customized to your specific drawing or sample. Our engineers are available to review designs for manufacturability before production begins.
We follow ISO 9001 standards and implement multiple inspection checkpoints throughout the production cycle. Every part is measured with precision instruments to ensure accuracy and consistency.
Can you work with tight tolerance components?
Yes. We are capable of holding tolerances of ±0.01mm, depending on the complexity of the part and the material used.
What materials do you support?
We machine a range of metals including aluminum, brass, copper, stainless steel, and carbon steel.
What kind of files can I send?
We accept most CAD formats such as STEP, IGS, STL, DWG, and PDF. You can also send a physical sample for reverse engineering.
Do you provide prototypes?
Yes, we offer sample machining and low-volume production. Typical lead time is 3 to 7 days for standard components.
Do you ship to the US and overseas?
We ship globally, with reliable carriers like FedEx, DHL, and UPS. Sea or air freight can also be arranged.
How is quality verified?
All components are inspected before delivery. Upon request, we provide dimensional reports and material certificates for traceability.
