Custom Machining Stainless Steel Parts CNC Machinery Parts Milling CNC

Machine Fabrication Service

 

Our CNC machining capabilities cover the spectrum, allowing us to fabricate parts of varying

complexities, from straightforward "as machined" workholdings to intricate geometries.

Operating an extensive array of CNC mills and turning centers, we can also incorporate EDM and

grinders based on your requirements. Precision is our hallmark, with tolerances reaching as low as

0.05 mm (0.0020 in), and our efficient processes ensure lead times starting at just one business day.

 

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
MaterialProperties
Aluminum2024: 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 SteelExcellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability
Steel AlloyMix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength
BrassVersatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing
TitaniumExcellent strength to weight ratio, used in aerospace, automotive, and medical industries
CopperHigh ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time
ABSExcellent impact resistance, good mechanical properties, susceptible to solvents
NylonExcellent mechanical properties, high toughness, poor moisture resistance
POMHigh 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.

Specialist industries

 

CNC milling, characterized by its efficiency, precision, and automation, is a transformative force

across various industries. Machine shops, serving as crucial entities in the manufacturing process,

provide essential services for prototypes and full production runs.

 

The electronics industry relies extensively on CNC machines for crafting components such as

electronic enclosures and circuit supports. In the commercial sector, CNC cutting heads play a

key role in producing cost-effective parts, streamlining production processes.

 

The oil and gas industry utilizes CNC machines for the fabrication of drill bits, cylinders, pins, rods,

valves, and more. The medical industry benefits from CNC milling in the production of diverse

components, including implants, surgical equipment, and medical devices.

 

Lastly, the aerospace industry demonstrates a constant demand for CNC machined parts, employing

this technology to create intricate, customized components vital for aerospace equipment.

Company Profile

FAQ's

 

1. What are the minimum and maximum dimensions you can machine?

 

Our CNC machining services encompass both milling (3-axis, 3+2-axis, and 5-axis) and turning

processes.

For 3/3+2-axis CNC milling, we can machine parts with dimensions up to 2000 x 1500 x 200 mm

(78.7 x 59.0 x 7.8 in.). In the case of 5-axis milling, the maximum part size is 650 x 650 x 300 mm

(25.5 x 25.5 x 11.8 in.).

 

When it comes to CNC turning, we can handle parts with a maximum diameter of 431 mm (17 in.)

and a length of 990 mm (39 in.). For smaller parts, we recommend a minimum size of around

10 x 10 x 10 mm (0.39 x 0.39 x 0.39 in.).

 

Additionally, feature dimensions should not fall below 0.5 mm. Please note that our platform is

limited to a maximum size of 1000 mm (39 in.) for parts. If you have requirements beyond this

limit, feel free to contact our sales team for specialized assistance.

 

2. Factors Influencing CNC Machining Costs:


The cost of CNC machining a part is influenced by several key factors, including:


1. Material: Variations in material costs arise as some materials, such as aluminum, are more

cost-effective to machine than others like Inconel due to increased tool wear and slower cutting

speeds.


2. Complexity: Parts with intricate features incur higher machining costs. Complex surface shapes,

for instance, are notably more expensive to machine compared to flat surfaces.


3. Tolerances: Stringent dimensional tolerances escalate machining costs. Specifying unnecessarily

tight tolerances on non-critical features can contribute to increased CNC machining expenses.


4. Surface Finish: Achieving mirror finishes necessitates specialized tooling and machining strategies,

extending machining time and subsequently increasing costs.


5. Quantity: Low-volume production inherently comes at a higher cost per part than large-volume

production. This is because initial setup and programming costs are distributed over a greater number

of parts in large-volume production.

 

3. What if I am not completely satisfied with the parts I receive?

 

Our commitment extends to guaranteeing the quality of our materials and workmanship in

accordance with the terms specified in the initial order and the information supplied by you.

 

Any disputes arising from subjective assessments will be addressed by our management, which will

make every effort in good faith to ensure your complete satisfaction. The foundation of our ongoing

business is built on earning your confidence in our capacity to meet and surpass reasonable

expectations.
