Surface Appearance | Material Name | Representative Grades | Key Characteristics | Typical Applications | Machinability |
---|---|---|---|---|---|
![]() | Cold Rolled Steel | SPCC (JIS), DC01 (EN), 1008/1010 (ASTM) | Smooth surface (Ra 0.5-1.5μm), high dimensional accuracy, tensile strength: 270-800 MPa | Auto bodies, appliance panels, precision parts | Excellent: Easy stamping & bending; welding requires rust prevention |
![]() | Galvanized Steel | GI (Zinc-coated), DX51D (EN), SGCC (JIS) | Zinc layer (5-20μm) prevents corrosion, sacrificial protection, lifespan 15-50 years | Roofing, ductwork, electrical cabinets, agricultural equipment | Good: Avoid grinding zinc layer; welding fumes require ventilation |
![]() | Stainless Steel | 304 (18% Cr, 8% Ni), 316 (Mo added), 430 (Ferritic) | Corrosion resistance (Cr content >10.5%), heat resistance up to 800°C, non-magnetic (austenitic) | Kitchen equipment, medical tools, chemical tanks, marine hardware | Moderate: Low-speed cutting needed, work hardening requires specialized tools |
![]() | Aluminum Sheet | 5052 (Mg alloy), 6061 (Mg-Si), 1100 (Pure Al) | Lightweight (2.7 g/cm³), conductivity 60% IACS, natural oxide layer corrosion protection | Aircraft panels, heat sinks, signage, packaging containers | Excellent: High-speed CNC machining, easy bending (min bend radius 1t) |
![]() | Tinplate | MR T-4 (Electrolytic), L T-1 (Low Sn), TH415 (Food grade) | Tin coating (0.1-1.5μm) for food safety, solderability, recyclable | Food cans, aerosol containers, battery shells, artistic crafts | Good: Avoid deep drawing cracks; welding requires tin removal |

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 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.
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.)
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.
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.
Each part must be visually consistent across the same batch.meaning:
* Manual brushing marks will be as unidirectional aspossible. Please note that for rounded geometries, brushingmarks may not be entirely unidirectional.*
The surface quality of every part must meet the followingconditions:
