Operating as a subtractive manufacturing process, CNC machining involves the creation of parts
by removing material from a workpiece or workpiece stock.
The machine's movement is governed by preprogrammed software and codes, ensuring precise
control over material removal. This expansive process includes a diverse range of machinery,
such as turning mills, lathes, grinders, and plasma-cutting machines.
Product Details
Our precision component manufacturing involves working with a range of materials, including
carbon alloys, aluminum, brass, stainless steel, high nickel alloys, and engineered plastics.
We pride ourselves on offering personalized assistance in material selection, ensuring that the
chosen material aligns seamlessly with your application's unique requirements.
Whether you're leaning towards the tried-and-true or exploring alternatives outside the
mentioned materials, our commitment remains unwavering: delivering precision components
tailored to your specifications.

CNC Machining Applications
Turning, a precision manufacturing process, specializes in creating rotational and axi-symmetric
parts endowed with various features such as holes, grooves, threads, tapers, and contoured
surfaces.
It excels in the production of limited-quantity components, particularly custom-designed shafts
and fasteners used in prototypes. Additionally, turning serves as a valuable secondary process,
allowing the addition or refinement of features to parts manufactured using alternative methods.
Noteworthy examples of products crafted through turning encompass camshafts, crankshafts,
baseball bats, bowls, cue sticks, signboards, musical instruments, and table and chair legs.

FAQ's
1. Understanding CNC Turning Tolerances
For CNC turned parts, our default tolerance is set at +/- 0.005”. Depending on the geometry
of your parts and the tools used, we can sometimes achieve even more precise tolerances.
If your project requires a tolerance tighter than our standard +/- 0.005”, kindly inform us
during the quoting phase. Our team will analyze your needs and offer insights into the available
options.
2. What cosmetic standards do you guarantee?
Upholding stringent quality standards, our CNC machined parts undergo standard deburring and
edge-breaking procedures. Clear indications in technical drawings are required for any critical
edges that should be left sharp.
Surfaces are guaranteed to be defect-free, ensuring the absence of scratches, dents, stains,
blemishes, hanging marks, and minor imperfections. Critical surfaces (primary (a) side,
as outlined in technical drawings) will be meticulously free from mill steps and other marks.
On the secondary (b) side, minor hanging marks and up to 2 minor defects are considered within
acceptable limits. Additionally, a range of post-processing and finishing methods can be applied to
enhance surface roughness, visual aesthetics, and wear resistance for CNC machined parts.
3. How much does CNC machining cost?
The cost of CNC machining is determined by factors such as complexity, quantity, and lead time.
To obtain a precise cost estimate, we encourage you to submit a 3D CAD model, enabling us to
provide an interactive quote accompanied by design for manufacturability (DFM) feedback.
Our use of proprietary software and automated fixturing processes eliminates upfront non-recurring
engineering (NRE) costs, making CNC machining a cost-effective choice for quantities as low as 1 to
200 parts. While prices may be comparable or slightly higher than 3D printing, CNC machining
delivers superior material properties and surface finishes.
