Frequently Asked Questions
Q1: What materials are available for your CNC machining service?
We process a wide range of materials, including Aluminum (6061-T6, 7075, 5052, A380, ADC12), Copper Alloys (brass, bronze, copper, phosphorous/beryllium copper), Stainless Steel (303, 304, 316, 17-4), Plastics (ABS, PP, PE, Delrin, Nylon, Teflon), and special materials like Inconel and titanium alloys.
Q2: What CNC machining capabilities do you offer?
We specialize in integrated CNC milling (3-axis, 4-axis, and 5-axis for complex structures), lathe turning (producing brass fittings, screws, shafts, and pins), gear hobbing, mechanical assembly, and large dimension parts up to 3m × 2m × 1.4m.
Q3: How do you guarantee the quality of your machined parts?
Our quality control involves semi-annual internal and annual third-party external calibrations. We comply with MIL-STD-105E sampling, PPAP, control plans, and standard operating procedures (SOPs) for large-scale projects.
Q4: What surface finishing options do you support?
We offer standard finishes depending on the materials used. For Aluminum: Anodizing (standard 4-16μm or hard 25-40μm, in various colors), sandblasting, and Alodine. For Steel: Passivation, polishing, black oxide, and zinc plating. For Brass: Gold, silver, nickel, chrome, and tin plating.
Q5: Are there options available to reduce the manufacturing cost of parts?
Yes, we offer cost reduction solutions depending on material choice. For aluminum, die casting combined with machining can reduce costs if anodizing or supreme surface quality is not critical. For steel parts, sand or investment casting plus final machining is recommended. Forging material can also be used to enhance high-strength parts.
Q6: How can I request a quote for custom CNC components?
You can simply send us your 2D or 3D engineering drawings. Our engineering team will review the specifications, tolerances, materials, and finish requirements to provide a fast and precise quotation.
