CNC Machining Surface Finishes
As Machined
The surface is left as-is after CNC machining, showing visible tool marks. It’s a cost-effective option for functional parts.
Anodizing
Enhances corrosion resistance and wear, with optional coloring. Ideal for aluminum parts.
Polishing
Creates a smooth, glossy finish with reduced surface roughness.
Sand Blasting
Produces a matte, uniform texture by blasting the surface with abrasive material.
Brushed Finish
Applies a thick, durable coating with various colors and textures.
Powder Coating
Applies a thin metallic layer to improve wear resistance, conductivity, and appearance.
Electroplating
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
Black Oxidize
A chemical treatment for ferrous metals to improve corrosion resistance and reduce reflectivity.
Electropolish
Removes surface imperfections chemically for a smooth, shiny, corrosion-resistant finish.
Alodine
Used on aluminum to enhance paint adhesion and corrosion resistance.

CNC Machining FAQS
Q1: What is CNC machining?
CNC machining is a precise, automated process that removes material from a solid block to create custom parts. It uses computer-controlled tools like mills and lathes.
Q2: What information do you need for a CNC machining quote?
Please send us 3D files (STEP, IGES) or 2D drawings with material, quantity, surface finish, and tolerance requirements. The more details, the more accurate the quote.
Q3: What is your typical lead time for CNC parts?
Prototype parts: 1–3 days
Small batches: 5–7 days
Mass production: depends on quantity
We also offer expedited services for urgent projects.
Q4: Can I get just one prototype part made?
Yes, we support low-volume and one-off production. CNC is ideal for making functional prototypes before moving to mass production.
Q5: What materials can you machine?
We work with a wide range of metals (aluminum, stainless steel, brass, copper, titanium) and plastics (ABS, POM, nylon, PC, PEEK, etc.).
Q6: Can you help optimize my part design for manufacturing?
Yes. Our engineering team provides DFM (Design for Manufacturability) suggestions to improve production efficiency and reduce costs.
Q7: What surface finishes can you provide?
We offer anodizing, polishing, powder coating, brushing, sandblasting, plating, black oxide, and more. Finishes enhance appearance and performance.
Q8: What tolerances can you achieve?
Standard tolerances: ±0.05 mm
High-precision parts: up to ±0.01 mm
We’ll confirm based on your design and material.
Q9: Can I use my own shipping account or forwarder?
Yes, we support EXW, FOB, DDP, and can work with your courier or freight forwarder upon request.
Q10: Are you ISO certified?
Yes, we are ISO 9001:2015 certified. Our quality control system ensures every part meets your requirements before delivery.
