Cosmetic Finishes

Surface finishes can have either a functional or aesthetic intent. Finishes that cater to both aspects are classified as cosmetic finishes and are frequently employed for enhancing the appearance of different parts. The fabrication of these parts demands additional measures to minimize defects such as tool-induced marks and scratches.

Non-comestic

There is no necessary to have aesthetic look. Machining veins will be seen primarily.

We accept small orders for CNC metal parts with a MOQ of 1 and can handle more complex CNC machining work, while we accept urgent orders. With LML, you can get the perfect products and thoughtful service you want, we are your friends in China.

Metal machining

Metal machining is the process of cutting down a raw piece of metal to create a desired shape or object. This process is done most accurately with a CNC (Computerized Numerical Control) machine, which can produce almost any three dimensional object designed via CAD (Computer Aided Design) software. Our network of machinists mainly uses 3- and 5- axis CNC machines for producing any metal parts that pass our online DFM checks. State-of-the-art metal CNC machines, like the ones we use, are able to cut complicated features on parts with great accuracy, while maintaining tight tolerances.

Metal 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 0.02mm (±0.0008 in.)

Metal CNC Turning

CNC turning shears materials from the ouside of a rod at incredible speeds using a spinning tool. At Rapid Direct, we apply 50+ CNC lathes and CNC turning centers to create round or cylindrical turned parts with extreme precision that consistantly meet customers’ expectations.be higher.

Defining an A and a B side

We can generate instant machining quotes for 50+ metals and plastics.

Surface finishing often leaves aesthetic defects on your parts, such as hang marks for anodizing. Defining an Aand a B-side in your design will ensure that the most important areas of your part remain free of defects In this image you can see how you can define an A-side and a B-side in your technical drawing: A side: Indicates the most aesthetically importantsurface, typically the visible side of your product. B side: Indicates the side that is not aesthetically important, typically the side hidden from visibility after assembly

For the primary surface (A-side) of your part, we guaranteedefect-free production. In contrast, secondary surfaces (B-side)may be machined with hanging marks and other minor defects. Bside surfaces, like the rest of your part, will be free of scratches.stains and blemishes.

Manufacturing vetted network of our service

We look forward to delivering high-quality products and professional services to meet your expectations and requirements.

Consistency requirements

Each part must be visually consistent across the same batch.meaning:

Same grit must be used across parts for sanding orbrushing
Brush marks must be in the same direction*
Color must be consistent to the same pantone when parts are placed next to each other
Gloss units must be consistent across the batch

* Manual brushing marks will be as unidirectional aspossible. Please note that for rounded geometries, brushingmarks may not be entirely unidirectional.*

Visual inspection conditions

The surface quality of every part must meet the followingconditions:

Distance: 50cm +10cm (19,7 in + 3,9 in) with a 10/10 vision(or corrected)
Incidence angle: Approximately 45 in all directions
Lighting conditions: 500-1000 Lux, color 3300-5300 Kelvin(neutral white)
