CNC Machining Service Stainless Steel Parts Turning CNC Machining For Aerospace

Parts

CNC machining, an abbreviation for Computer Numerical Control machining, operates as a

subtractive manufacturing technology, autonomously removing material from raw stock guided

by computer-generated instructions. Generally, CNC machines can be classified into two types:

those that keep the raw stock stationary while rotating the cutting tool, and those that rotate the

raw stock while moving it against a stationary tool.

Various modifications and combinations of these fundamental approaches are employed, allowing

some machines to integrate both techniques for the production of intricate parts with complex

features.

Product Details

CNC machining machines possess the versatility to cut through an extensive array of materials,

encompassing aluminum, bronze, copper, ceramics, plywood, diverse steel types, stone, wood,

zinc, and various engineering materials.

This broad range of capabilities positions CNC machining as an optimal solution for prototype

creation in product development. It facilitates the ability to make accurate and swift adjustments

until achieving satisfaction with the final product.

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.

Applications of CNC Turning

CNC turning services stand at the forefront of various industries, particularly in the transportation

sector encompassing aerospace, automotive, mass transit, rail and locomotive, military, and trucking.

These services are integral to the creation of transportation equipment, including headnuts, gear

blanks, bearing blocks, levers, axles, and rotors, utilizing the precision of CNC machines.

In the construction industry, CNC turning is employed to manufacture robust bolts and screws from

materials like stainless steel and aluminum, catering to the demanding requirements of

heavy-duty applications.

Additionally, CNC turning services contribute significantly to the automotive sector, producing

essential components such as cylinder heads, connecting rods, camshafts, shafts, rings, sway bars,

control arms, tie rod ends, bushings, and bolts. The aviation industry, known for its exacting

standards, relies on CNC turned parts for probes, joint connectors, fasteners, and engine and

aircraft components, often opting for titanium due to its resilience in extreme temperature

conditions.

FAQ's

1. The cost of CNC machining a part depends on a range of factors, some of which

are listed below:

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.

2. What are your tolerances for machined parts?

For machined parts, our tolerances typically adhere to +.005”/- .005” local tolerances across most

metal geometries and +/- 0.010" for plastics. It's important to note that these tolerances may vary

for large parts, especially concerning flatness after heat treatment.

For an "As Milled" finish, a minimum surface finish of 125 is maintained for CNC parts.

Fabricated parts come with a 0.010” dimensional tolerance and a 1° angular tolerance.

Tapped holes not explicitly designated as features in the CAD model may be machined to the

diameters specified.

Additionally, no surface treatments, such as anodizing, bead blasting, iriditing, powder coating,

etc., will be applied unless expressly paid for and acknowledged.

3. Why choose CNC machining?

Opting for CNC machining brings forth speed, accuracy, and versatility. This manufacturing solution

stands out as it swiftly delivers end-use parts at any volume without the requirement for

substantial investments in hard tooling or costly set-ups.

4. How long does delivery time and quotation take?

The delivery time for parts is determined by their complexity. Parts with low complexity typically

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

High-complexity parts may require 5 to 15 days for delivery. Quoting time varies based on design

complexity, ranging from 1 business day (or faster) for simpler designs to 3+ business days for

more intricate ones. For an assessment and quote for your design, please feel free to reach out
