Parts

CNC machining, short for computer numerical control machining, is a subtractive manufacturing

technique that utilizes computerized controls and machinery to selectively remove material layers

from a solid block. Precise cuts in the material are orchestrated through programmed instructions,

allowing automated machinery to execute the machining tasks with accuracy and efficiency.

Product Details

The CNC machining process predominantly employs metals as its primary materials.

These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,

magnesium, and zinc.

Nonetheless, this versatile process can also be applied to machine plastic components and work

with an array of other materials, including ceramics, composites, thermoplastics, and thermosets.

Post-processing and surface finishes for CNC machining

CNC-machined parts as they emerge from the machine often exhibit visible tool marks,

a feature that may not align with your specific part requirements.

Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the

surface appearance and elevating attributes such as wear resistance, corrosion resistance,

and chemical resistance.

Methods like anodizing, bead blasting, and powder coating present viable options for refining

the final presentation of your custom parts, allowing you to achieve the desired surface

quality and performance characteristics.

Specialist Industries

CNC machining stands as a cornerstone in subtractive manufacturing, playing a pivotal role in

numerous industries. Some of the most prominent sectors leveraging CNC machining include:

1. Aerospace: Precision and reliability are non-negotiable in aerospace applications. CNC machining

is crucial for producing intricate and accurate components for aircraft and spacecraft, meeting the

demanding standards of the industry.

2. Automotive: The automotive sector relies heavily on CNC machining for the fabrication of precision

parts, contributing to the efficiency, performance, and safety of vehicles.

3. Aviation: Similar to aerospace, the aviation industry benefits from CNC machining's precision in

crafting components that adhere to strict quality and safety regulations for optimal aircraft

performance.

4. Transportation: Beyond air and land, the transportation industry, encompassing rail and maritime

sectors, integrates CNC machining for the production of robust and precise components that endure

challenging operational conditions.

These industries showcase the versatility of CNC machining, where its capabilities are harnessed to

meet the stringent demands of manufacturing in sectors where precision, durability, and quality are

of utmost importance.

FAQ's

1. Can you ensure my designed component dimensions and tolerances are suitable for

production?

Count on our team of experienced professionals to provide robust "Design for Engineering" (DFM)

support, ensuring that your designed component dimensions and tolerances are suitable for

production. We understand the need for quick turnarounds during the idea testing phase and are

committed to providing prompt quotes.

For a detailed overview of the entire order progression, refer to our production process page.

2. What tolerances can achieve?

Tolerances are not universally defined and vary based on factors such as part size, design geometry,

the number and size of features, material selection, surface finish, and the manufacturing process.

After order confirmation, we conduct a comprehensive Design for Manufacturing review to identify

areas for potential modification to enhance manufacturability. It is advantageous if you can specify

critical tolerance areas in your design, allowing for adjustments to optimize production time and costs.

General tolerance guidelines are provided for CNC machining in metal and plastic, plastic injection

molding, CNC metals and plastic injection molding materials, metal 3D printing (+/- 0.5mm), and an

expected shrinkage rate of +/- 0.15% for vacuum casting.

Clear specifications in the 2D drawings are essential for precise adherence to manufacturing and

technical requirements.

3. How do I know my design will be kept confidential?

Your design's confidentiality is paramount to us. We are willing to sign and strictly adhere to any

non-disclosure or confidentiality agreement. Moreover, our factory has a stringent policy against

taking photographs of a customer's product without explicit permission.

Our reputation is founded on years of experience working with a multitude of unique designs, and

we have never allowed any proprietary information to be disclosed to third parties.
