Introduction to the common process of cnc metal materials
Metal CNC services
LML provides the most advanced CNC metalworking services to ensure superior product quality and fast delivery. We have more than 60 metal milling machines and metal lathes that we can offer with the capacity and competitive prices. 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 RapidDirect, 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.

The metal part can serve as functional or aesthetic purpose,and the way of usage will decide on the type of surface finish.Defining an A and a B side
Surface finishing often leaves aesthetic defects on yourparts, 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 drawina:
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
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)

- The difference between high borosilicate glass and soda lime glassSep 17,2023High borosilicate glass is mainly composed of three elements: silicon, boron and oxygen. The boron content is high, which can improve the heat resistance and corrosion resistance of the material. Soda-lime glass is composed of elements such as sodium carbonate, calcium oxide, silicon and oxygen. The higher sodium and calcium content can improve the material's impact resistance and light transmittance.
