China CNC Machining Parts Milling CNC Machining Processing CNC Mill Parts

The CNC machining process, standing for computer numerical control machining, is a subtractive

manufacturing approach that utilizes a synergy of computerized controls and machine tools to

eliminate layers from a solid block of material. Programming dictates the desired cuts in the metal,

aligning them with specific tools and machinery, and the automated process executes the

machining task accordingly.

Product Details

CNC milling machines excel at cutting a wide range of materials, including aluminum, bronze,

copper, ceramics, plywood, various steel types, stone, wood, zinc, and numerous engineering

materials.

This versatility makes them perfect for crafting prototypes during product development.

With CNC milling, you can easily fine-tune and make precise adjustments until you achieve

the desired final product, offering accuracy and efficiency throughout the manufacturing process.

Specialist Industries

The utility of CNC milling machines extends across the production spectrum, catering to materials

like glass, metal, plastic, wood, and customized components. This precision machining method is

pivotal in generating prototypes and final products for an array of industries, encompassing

aerospace, automotive, hardware startups, manufacturing, medical devices, robotics, and more.

The adaptability of CNC milling machines underscores their significance in modern manufacturing

processes.

FAQ's

1. The cost of CNC machining a part is shaped by a variety of factors, including:

1. Material: Material selection introduces cost variations, with materials like aluminum being

more economical to machine compared to others like Inconel, attributed to factors such as tool

wear and cutting speeds.

2. Complexity: Parts featuring intricate designs incur higher machining costs. The complexity

of surface shapes, for instance, significantly influences overall machining expenses.

3. Tolerances: The precision demanded by dimensional tolerances impacts CNC machining costs.

Imposing overly tight tolerances on non-critical features can lead to unnecessary cost escalation.

4. Surface Finish: Achieving mirror finishes demands specialized tools and machining strategies,

extending machining time and, consequently, increasing costs.

5. Quantity: Production volume is a key determinant of costs. Low-volume production tends to be

costlier per part, as initial setup and programming costs are distributed over a smaller production

run.

2. What are your tolerances for machined parts?

Our machined parts adhere to precision standards, featuring +.005”/- .005” local tolerances across

most metal geometries and +/- 0.010" for plastics. It's worth noting that tolerances may vary for

larger parts, especially with considerations for flatness post heat treatment.

An "As Milled" finish for CNC parts requires a minimum surface finish of 125. Fabricated parts

maintain a 0.010” dimensional tolerance and a 1° angular tolerance. Tapped holes not explicitly

labeled as features in the CAD model may be machined based on the specified diameters.

Crucially, surface treatments such as anodizing, bead blasting, iriditing, powder coating, etc.,

will only be applied upon explicit payment and acknowledgment.
