FAQ of precision machining manufacturer
Metals: Stainless steel (304/316L), titanium alloy (Ti-6Al-4V), aluminum alloy (7075/6061), nickel-based alloy (Inconel 718), copper alloy (C36000), etc.
Plastics: PEEK, PPS, PTFE, nylon (PA66), polycarbonate (PC);
Composites: Carbon fiber reinforced plastic (CFRP), ceramic matrix composite (CMC).
For high-temperature alloys or carbides, we use diamond-coated tools and cryogenic cooling technology to avoid work hardening. For example, the surface roughness of an Inconel turbine blade machined for an aircraft engine customer reached Ra 0.4μm.
Design Support: Perform design for manufacturing (DFM) analysis using SolidWorks/UG to optimize the structure and reduce manufacturing costs;
Prototyping: Rapid proofing within 3 days, supporting small-batch trial production (10-100 pieces);
Mass Production: Automated production lines achieve a daily capacity of over 5,000 pieces, equipped with in-line inspection systems (such as Keyence laser sensors);
Post-Processing: We offer surface treatments such as anodizing, electroplating, sandblasting, and laser engraving, and support assembly testing (such as airtightness testing).
A medical client previously used this service to reduce their catheter connector development cycle from 8 weeks to 3 weeks.
Equipment Calibration: All CNC machine tools undergo monthly laser interferometer calibration to ensure positioning accuracy of ±0.002mm;
Process Control: We utilize SPC statistical process control to monitor cutting forces, vibration, and other parameters in real time;
Inspection Standards: We perform first article inspection (FAI), patrol inspections, and final inspections in accordance with AS9100D (Aerospace) or ISO 13485 (Medical) requirements;
Traceability System: Each part is assigned a unique QR code that records information such as processing time, operator, and inspection data.
For example, we have produced vacuum chambers for a semiconductor equipment customer with a zero-defect record of 100,000 units.
Prototypes: 3-5 business days;
Small batches (100-1000 pieces): 7-15 business days;
Large batches (>1000 pieces): By negotiation, partial delivery is possible.
MOQ: No hard limit, with a minimum order of 1 piece. For complex parts (such as five-axis machining), a minimum of 10 pieces is recommended to spread the programming costs.
