CNC Machining Services Custom Steel Lathe Parts CNC Machining Milling Parts

CNC machining, standing for computer numerical control machining, is a prevalent manufacturing

process that employs automated, high-speed cutting tools to shape designs from metal or plastic

stock. Standard CNC machines encompass 3-axis, 4-axis, and 5-axis milling machines, lathes,

and routers.

Variations exist in how CNC parts are cut, with possibilities such as the workpiece remaining

stationary while the tool moves, the tool staying in place while the workpiece is rotated and moved,

or both the cutting tool and workpiece moving together.

Product Details

Stainless steel is highly resistant to corrosion and rust, making it suitable for situations

where a part may be exposed to the elements for a long period of time. Stainless steel is also

fairly malleable and ductile.

Stainless Steel Finishing and Post-Processing

The finish of stainless steel can vary significantly depending on the surface roughness.

However, it is typically described as shinier compared to unfinished aluminum alloys,

and it tends to have a slightly darker and more silver color.

Stainless steel offers flexibility in achieving various surface finishes, including options such as

media blasting, sanding, hand-polishing, and powder coating.

These processes can be employed to achieve a wide range of surface finish textures and

appearances.

CNC Machining Applications

CNC milling machines find extensive application in the contemporary manufacturing landscape,

shaping materials ranging from glass and metal to plastic, wood, and custom-designed components.

Machinists proficient in CNC machining are instrumental in fabricating prototypes and end products

for diverse sectors like aerospace, automotive, hardware startups, manufacturing, medical devices,

robotics, and other burgeoning industries. The precision and versatility of CNC milling machines

contribute significantly to the evolution of manufacturing technologies.

FAQ's

1. What are standard machining tolerances?

Standard machining tolerances are set at ± 0.005" or 0.13mm, delineating the acceptable range

for dimensions. For example, if a CNC machining tool carries a tolerance of ± 0.01 mm, it signifies

a permissible deviation of 0.01 mm in each cutting operation. Leveraging a provided drawing, our

CNC machining service can attain part tolerances as precise as ± 0.0002 in.

In cases where no drawing is available, all CNC parts adhere to our ISO 2768 medium standard.

Projects requiring even tighter tolerances, such as ±0.025mm or ±0.001", can be accommodated

with an engineering drawing specifying critical features.

2. Why choose CNC machining?

The choice of CNC machining is characterized by its speed, precision, and versatility.

This manufacturing solution distinguishes itself by efficiently producing end-use parts across various

volumes, all without the necessity for significant investments in hard tooling or elaborate set-ups.

3. How long does delivery time and quotation take?

The delivery time for parts is intricately tied to their complexity. Low-complexity parts usually have

a lead time of 2-3 days, while moderate complexity extends to 2-5 days. High-complexity parts

may necessitate a lead time ranging between 5 and 15 days.

Quoting time is also linked to design complexity, ranging from 1 business day or faster for simpler

designs to 3+ business days for more intricate ones. If you have a design that requires assessment

and quoting, do not hesitate to contact our team.

4. What are the advantages of CNC machining?

CNC machining offers a spectrum of advantages, prominently featuring rapid prototyping and the

expedited production of full-scale parts. Its hallmark is the ability to achieve exceptional precision

and accuracy in manufacturing, catering to tight tolerances for CNC parts of diverse sizes.

This method stands out for its flexibility, influencing factors such as volume, pricing, lead times,

and the array of materials and finishes available.
