What is Metal Stamping?
CNC machining is a manufacturing process in which pre-programmed computer software directs the movement of factory tools and machinery, which can be used to control a range of complex machinery, from grinders, lathes to milling machines and CNC routers. The automated control system can logically solve the program flow with manipulation numbers or other marker command requirements, decode them according to the electronic computer, and then operate the machine and machine the part. CNC machines include three-, four- and five-axis milling machines, lathes and routers.CNC machining G code to be able to manual service program writing, but the general machine shop with CAM (auxiliary design manufacturing) fully automated loading CAD (auxiliary design design program) documents and into G code program process, the CNC machine tool to carry out manipulation. LML offers CNC services and offers custom CNC quotes for over 80 materials and 35 finishes.Get Instan Quote

Metal Stamping Tolerances
"Precision Perfected: Embrace the Power of CNC Machining Tolerance for Immaculate Precision in Every Dimension."We follow ISO 2768 standards for CNC machining.
| Limits for nominal size | Plastics (ISO 2768- m) | Metals (ISO 2768- f) |
|---|---|---|
| 0.5mm* to 3mm | +0.1mm | +0.05mm |
| Over 3mm to 6mm | +0.1mm | +0.05mm |
| Over 6mm to 30mm | +0.2mm | +0.1mm |
| Over 30mm to 120mm | +0.3mm | +015mm |
| Over 120mm to 400mm | +0.5mm | +0.2mm |
| Over 400mm to 1000mm | +0.8mm | +0.3mm |
| Over 1000mm to 2000mm | +1.2mm | +0.5mm |
| Over 2000mm to 4000mm | +2mm | +0.5mm |
Metal Stamping Design Guideline
| Feature | Description |
|---|---|
| Inner corner fillets | Design the inner corner rounding to be 0.020 " - 0.050" larger than the standard drilling diameter. Follow the ratio of drilling diameter to depth 1:6 (1:4 recommended) as a guideline for the radius of the inside corner radii. |
| Undercuts | Always design undercuts to standard sizes and away from corners to allow for cutting tools. |
| Tapped/threaded hole depth | Provide tool clearance slightly beyond the depth of the tapped hole to ensure a complete thread. |
| General tolerance | Tolerances on metals wil be held to +/- 0.005*(+/- 0.127 mm) inaccordance with 1SO 2768 unless otherwise specified. Plasticsand composites will be +/- 0.010”. |
| Threading | We currently support UNC and UNF threads from #2 up to 0.5 in., and metric threads from M2 to M12. Avoid modeling internal threads on your part design. |
| Complexity | Keep the number of small cuts to a minimum to reduce CNC machining costs; only design in the necessary features to balance function with aesthetic. |

How does LML’s custom CNC machining service work?
CNC Machining includes CNC turning and CNC milling, which is widely used in automotive, communication, medical, clocks and watches, cell phones, computers and other industries. Machining of mechanical parts generally refers to the sum of the machining process of parts and the assembly process of machines, and other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc.
CNC machines manufacture robust parts with tight tolerances and a range of impressive material properties (mechanical and chemical). Our custom CNC machining service is ideal for one-off jobs and low-to-medium volume production, thanks to automation and high repeatability.
