Q1. Are CNC machined parts durable?
Yes, CNC machined parts are highly durable. Precision machining ensures accurate dimensions, excellent mechanical strength, and consistent performance. With the right material (stainless steel, aluminum, brass, etc.) and surface finish (zinc plating, anodizing, polishing), CNC parts can withstand corrosion, wear, and long-term industrial use.

Q2. What materials can be used for CNC machining?
We offer a wide range of material options, including stainless steel, aluminum, carbon steel, alloy steel, brass, and copper. Each material provides unique advantages such as corrosion resistance, electrical conductivity, or high strength, making them suitable for different industries like automotive, aerospace, and construction.

Q3. How precise are CNC machined components?
Our CNC machining services achieve tight tolerances, typically ±0.01 mm or according to customer requirements. High-precision machining ensures parts fit perfectly in assemblies, which is critical for automotive, aerospace, and high-performance mechanical applications.

Q4. Can CNC machined parts be customized?
Yes, all CNC parts can be fully customized. We provide OEM/ODM services, supporting custom designs, drawings, sizes, materials, and surface finishes. Small MOQ, rapid prototyping, and bulk production are available to meet your project needs.

CNC Machining Order Procedure

Step 1 – Submit Drawing / Sample

Provide 2D/3D drawings (PDF, STEP, IGS, DWG) or a physical sample.
👉 We evaluate feasibility, machining process, and tolerance requirements.

Step 2 – Quotation & DFM Review

Within 1–3 working days, we provide a quotation.
👉 Includes material, surface treatment, lead time, and cost.
👉 Design for Manufacturability (DFM) review to optimize production.

Step 3 – Prototype / Sample Approval

CNC prototypes or pre-production samples are produced.
👉 Used for quality check, dimensional accuracy, and surface finish confirmation.
👉 Buyer approves before mass production.

Step 4 – Mass Production

Upon approval, mass production is launched.
👉 Strict QC in every process (machining, heat treatment, surface finish).
👉 Lead time usually 2–4 weeks depending on volume.
