If you need custom machined parts with complex geometries, or get end-use products in the shortest possible time, cncjsd is good enough to break through all of that and achieve your idea immediately. We operate over 150 sets of 3, 4, and 5-axis CNC machines, and offer 100+ different types of materials and surface finishes, guaranteeing quick turnaround and quality of one-off prototypes an💦d productio🔴n parts.
CNC Milling
CNC milling removes materials from the workpiece to create custom-designed parts with flat surface using cutting tool or multi-point milling cutters.WIth our 3-axis & 5-axis CNC milling services, you can get milled parts with tight tolerance up to +-0.005mm (+-0.0002 in.)
CNC Turning
CNC turning shears materials from the ouside of a rod at incredible speeds using a spinning tool. At cncjsd, we apply 50+ CNC lathes and CNC turning centers to create round or cylindrical turned parts with extreme precision that consistantly meet customers’ expectations.
From CNC Prototyping to Production
CNC machining is a computerized and versatile manufacturing process ideal for rapid prototyping and on demand productio♊n. Here are the custom CNC se✅rvices available at the cncjsd.
Rapid Prototyping
With our instant quotation platform and strong capacity, you can get excepted prototypes in short lead times. This allows you to quickly test pro🐼totype parts and get them to market.
Bridge Production
Bridge-to-production is critical for closing the gap between the part design and the actual product rollo🧸ut. No worries. Our professional🥀 engineering team is always ready to provide practical design suggestions for your low volume machined parts.
On-Demand Production
Our full service for on-demand pr🌼oduction orders ensures that you get high precison and high standard of quality products. Enhanced production rate also allows for just-in-time delivery of production parts.
CNC Machining Tolerances and Standards
With precision CNC machining services, cncjsd is your idea🍎l partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your require💞ments on your drawing.

Surface Finishes for CNC Machining
CNC machining leaves visible tool marks during the process of removing portions of the block’s surface to create desired shapes. If don’t want ꩲas-machined parts, select a surface finishing for your custom parts. At cncjsd, ⛄we offer several common surface finishes that help improve functionality and aesthetics.

Materials
Color
Texture
Link
Anodizing
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.
Aluminum
Clear, black, grey, red, blue, gold.
Smooth, matte finish.
-
Bead Blasting
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
ABS, Aluminum, Brass, Stainless Steel, Steel

Matte
-
Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Aluminum, Stainless Steel, Steel
Black, any RAL code or Pantone number
Gloss or semi-gloss
-
Electroplating
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Aluminum, steel, stainless steel
n/a
Smooth, glossy finish
-
Polishing
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Aluminum, Brass, Stainless Steel, Steel

Brushing
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.
