CNC Machining

A Versatile Solution for Custom Metal and Plastic Components

CNC machining represents the predominant subtractive manufacturing technology in contemporary

industrial processes. It stands as an exceptionally flexible and robust method for the production

of tailor-made metal and plastic parts.

Leveraging CAD models, CNC machines execute precise material removal from solid blocks through

a diverse range of cutting tools.

Cost Considerations for CNC Machining Materials

The cost of materials in CNC machining can fluctuate significantly due to the extensive array of

available options. Each material carries its unique price tag, and the inherent physical properties

of each material play a substantial role in determining machining costs.

For those seeking to manufacture metal components, Aluminum 6061 stands out as the most

cost-effective choice.

On the other hand, ABS ranks as the most budget-friendly option among materials.

As for the influence of machining complexity on costs, stainless steel serves as an illustrative example.

Its inherent hardness, surpassing that of aluminum, renders it more challenging to machine,

consequently elevating the overall machining expenses.

Here is a comprehensive overview of the most popular materials.

FAQ's

1. What's the general surface texture of CNC milled and turned parts?

In the realm of CNC machining, as-machined milled parts typically exhibit a surface roughness

of approximately 3.2μm (or 1.6μm in the case of relatively new machines). On the other hand,

when it comes to turned parts, we can achieve a smoother surface with a roughness of 0.8μm.

This means that machining speed adjustments are not necessary to attain this level of surface finish.

2. What tolerance standards do you guarantee?

We assure that our factory adheres to ISO 2768 standards for all CNC machined parts.

For parts machined with metals, we strictly follow ISO 2768-m (medium) or ISO 2768-f (fine) standards.

In the case of parts machined with plastics, we comply with 2768-m (medium) standards.

While geometric tolerances as tight as ± 0.0004 inches (0.010 mm) are attainable,

it is imperative that they are clearly specified in the technical drawings.

We can achieve even finer tolerances on shafts, with up to H7 fits, through manual quoting and,

on occasion, even tighter ones.

3. How can I reduce the cost of my machined parts?

Costs associated with CNC machining can be categorized into machining time, start-up expenses,

material expenditures, and feature-related costs. To effectively reduce overall costs, it is essential

to comprehend the influence of these factors on the final expense.

1. One of the most effective means to minimize machining time is through the strategic design of

features that can be machined swiftly. This entails making choices such as opting for appropriate

radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread lengths,

and designing holes with standard dimensions.

2. To curb material costs, thoughtful consideration should be given to the size of the initial blank

required and the cost-effectiveness and machinability of the base material. Softer alloys, for instance,

tend to be faster to machine.

3. Start-up costs can be mitigated by minimizing the number of part rotations or repositioning steps

needed to complete the component. This can be achieved by dividing complex geometries into multiple

parts that can be subsequently assembled.

4. In terms of feature costs, it is prudent to employ tolerances only when absolutely necessary,

eliminate all text and lettering, and steer clear of multiple surface finishes whenever possible.

These measures collectively contribute to cost reduction in CNC machining projects.
