Surface Finishes

CNC Machining Surface Finishes

CNC machining can cause visible tool marks on the machined parts due to eliminating areas from the metal block’s surface to give it the desired shape. To improve aesthetics, you can give it a different surface finish. Select from here.

bead blasting

Bead Blasting

The bead blasting process gives CNC machined parts a matter texture and smooth surface, ideal for visual applications for aluminum, stainless steel, brass, and ABS. Also, for other surface treatments, this process is commonly used.

Powder Coating

It’s another popular surface finish used for steel, stainless steel, and aluminum CNC machined milling parts as a dry powder, free-flowing and applied electrostatically. Finally, cure it under direct heat or ultraviolet light to give it a glossy or semi-glossy finish.

Anodizing

Do you want your CNC-machined prototypes and parts to be wear and corrosion-resistant? An anodized surface finish allows hardness to the metal surface, making it ideal for automobile, aircraft, and mechanical parts.

Createproto electroplating

Electroplating

Mostly, in the automotive sector, the demand for the electroplating process is high to make aluminum, stainless steel, or steel parts to make them functional, aesthetic, and corrosion-resistant. It gives a smooth and glossy finish.

Brushing

For CNC machined parts, we use brushing as a surface treatment to give ABS, brass, aluminum, and steel prototypes and parts a satin finish. Here, we use abrasive belts to draw traces on these material surfaces to enhance aesthetics.

CNC (Computer Numerical Control) Machining is a manufacturing process to create detailed components eliminating material layers using precise machining and tooling to meet the exact specification.

The process is designed by CAD software and converted into machine commands. CNC machines read those commands and cut, shape, and produce the finished part with precision matching your digital design.

The best advantage you can take from CNC machining is unmatched accuracy and repeatability. Also, it can handle a variety of materials, from plastics to metals, while offering fast turnarounds and consistent quality, making it the best choice for industrial applications.

CNC machining is a subtractive process (removing parts from the initial material block) and 3D Printing is an additive manufacturing procedure (depositing material layer by layer). 3D printing is best for rapid prototyping and complicated geometries, whereas CNC machining is ideal for versatility, precision, and durability.

The maximum dimensions for CNC machining are 2000 mm x 1500 mm x 300 mm to facilitate large machined parts and prototyping for plastics and metals. Using this measurement, we can also accommodate tailored parts for different applications.

Yes, we follow the highest accuracy of metal components, which is +/-0.01and +/-0.02 for plastic parts, to ensure higher precision. However, as per requirements, we also meet the tolerances needed.

We have a huge team of technical experts to meet on-demand production with more than 100 mills, 3D printers, lathes, and other mechanical tools. Our capacity to produce CNC parts is up to 10,000+ parts within two weeks.

We use aluminum, brass, stainless steel, steel, bronze, ABS, and copper to produce CNC machined parts. However, the availability of specific materials can be different.

At CreateProto, our price for CNC machined parts starts from around $65 but can be varied based on your desired product design, complexity, choice of materials, and quantities. So, get a quote before for an estimated price!

We supply for both small and large-scale low-volume productions and rapid prototyping. So, whatever your needs are, we strive to meet on-demand production.

It depends on your design complexity, choice of material, and our current workload. However, with CNC machining, you can expect a fast turnaround, quality consistency, and in-time delivery.
