CNC Milling Fabrication CNC Machining Parts Precision Aluminum Parts CNC
Machining Parts
The process of our custom CNC machining service involves leveraging the predominant subtractive
manufacturing technology of CNC machining. This method is particularly effective in crafting
bespoke metal and plastic parts for both prototyping and production needs.
Through the utilization of CAD modeling software and G-code, CNC milling and CNC turning
machines meticulously remove material from solid workpieces with precision and efficiency.
Our service excels in delivering sturdy components with stringent tolerances and diverse material
properties, both mechanical and chemical. Its applicability extends seamlessly to one-off projects
and low-to-medium volume production, facilitated by automation and high repeatability.
Product Details
CNC machining materials are generally grouped into three primary categories: plastics, soft metals,
and hard metals. This classification includes materials such as aluminum, bronze, copper, ceramics,
plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.
| 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. How much do CNC machining materials cost?
The multitude of materials available for CNC machining introduces a range of costs, influenced
by the unique properties and characteristics of each material. In the realm of metal parts,
Aluminum 6061 is a standout for its economical pricing.
If cost efficiency is a priority, ABS takes the lead as the most budget-friendly option.
Importantly, the ease of machining is a key factor impacting costs.
Stainless steel, known for its hardness in comparison to aluminum, presents higher machining
complexities, contributing to an overall increase in costs.
2. Why choose CNC machining?
CNC Machining: Swift, Accurate, and Versatile Manufacturing:
The decision to leverage CNC machining is driven by its attributes
of speed, accuracy, and versatility.
This manufacturing solution excels in delivering end-use parts across different volumes with notable
efficiency, eliminating the need for substantial investments in hard tooling or intricate set-ups.
3. What are you shipping terms?
Our standard shipping terms, applicable to both rapid prototyping and regular production orders,
are Ex Works (EXW). Under these terms, the customer assumes responsibility for shipping, customs
clearance, and all associated fees once the goods have left our premises.
For express shipments, we follow the Delivered Duty Unpaid (DDU) model, placing the onus on the
client to pay import duty upon the goods reaching their destination.
4. Can passivate my parts?
Passivation is a treatment designed to change the surface chemistry of select metals. We offer
passivation services to provide corrosion protection, improve durability, enhance aesthetics, and more.
