Machining Service
In the realm of metal fabrication, milling stands out as the most
prevalent method for material
removal. CNC milling machines, renowned for their exceptional precision and accuracy,
find extensive application in cutting an array of metals.
The outcome of milling can vary depending on factors such as the material's type, strength,
and hardness. Certain metal alloys, like titanium, exhibit exceptional durability and can withstand
demanding environments.
Other noteworthy metal alloys encompass aluminum, copper, brass, zinc, bronze, stainless steel,
and steel. Metal milling encompasses processes such as shaping, cutting, drilling, and tapping.
Product Details
CNC milling machines excel at cutting a wide range of materials, including aluminum, bronze,
copper, ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering
materials.
This versatility makes them perfect for crafting prototypes during product development.
With CNC milling, you can easily fine-tune and make precise adjustments until you achieve the
desired final product, offering accuracy and efficiency throughout the manufacturing process.
| Common Materials for CNC Machining | |
| Material | Properties |
| Aluminum | 2024: Good fatigue resistance and strength; excellent toughness at moderate to high strength levels; improved fracture toughness |
| 6061: Excellent machinability, low cost, and versatility | |
| 7075: High strength, hardness, low weight, and heat tolerance | |
| Stainless Steel | Excellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability |
| Steel Alloy | Mix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength |
| Brass | Versatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive, and medical industries |
| Copper | High ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time |
| ABS | Excellent impact resistance, good mechanical properties, susceptible to solvents |
| Nylon | Excellent mechanical properties, high toughness, poor moisture resistance |
| POM | High stiffness, excellent thermal & electrical properties, relatively brittle |
CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design complexity,
the number and size of features, materials used, surface finish, and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production time and cost.
| CNC Milling Tolerances | ||
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes, below 0.5mm on your technical drawing. | ||

FAQ's
1. Why choose CNC machining?
CNC machining offers speed, precision, and versatility that stand out among manufacturing
solutions. It can produce end-use parts in any quantity without requiring significant investments
in hard tooling or costly setups.
2. How much do CNC machining materials cost?
The cost of CNC machining materials can vary significantly due to the wide range of materials
available for this process.
Each material comes with its own unique price point, and the physical characteristics of the chosen
material also play a role in determining the overall machining cost.
For those looking to produce metal parts, Aluminum 6061 often stands out as the most
cost-effective option.
On the other hand, if you're considering plastic materials, ABS typically ranks as the most
budget-friendly choice.
Moreover, the ease of machining a particular material can impact its cost.
Stainless steel serves as a prime example of this. Given its higher hardness compared to aluminum,
machining stainless steel can be more challenging, which in turn tends to raise the overall
machining cost.
3. Machined Part Tolerances Explained
For most metal geometries, our tolerances are within +0.005" / -0.005". For plastics, it's typically
+/- 0.010". Tolerances may vary for large parts, especially those requiring flatness after heat
treatment.
"As Milled" finish requires a minimum 125 surface finish for CNC parts.
All fabricated parts adhere to a 0.010" dimensional and 1° angular tolerance.
Tapped holes not explicitly noted in the CAD model will match the specified diameters in that model.
Surface treatments like anodization, bead blasting, iridite, powder coating, etc., are only applied if
paid for and acknowledged in advance.
