Custom Precision CNC Machining Metal Machining 420 Stainless Steel CNC Lathe
Turning Part
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 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.
| CNC Turning Tolerances |
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
| *Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing. |
Applications of CNC Turning
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.
Company Profile
FAQ's
1. How long does delivery time and quotation take?
The lead time for parts is contingent on their complexity. Parts with low complexity typically boast
a lead time of 2-3 days, while moderate complexity extends the lead time to 2-5 days.
High-complexity parts may require a lead time ranging from 5 to 15 days.
Quoting time is influenced by design complexity, with a range of 1 business day (or faster) for
simpler designs to 3+ business days for more intricate ones.
If you have a design awaiting assessment and quoting, feel free to get in touch with our team.
2. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In cases where no specific fillet radius is specified in the 3D model or drawing, fillet radii will be
added by the machinist based on their judgment to enhance machining ease.
To ensure a desired fillet radius, specific details should be provided. For a general understanding,
internal vertical edge radii might surpass 1/3 of the depth, and internal horizontal edges may
either be maintained sharp or incorporate a radius within the range of 0.5mm to 1mm.
3. What industries do you typically work in? Who are your typical customers?
Virtually no industry is unfamiliar to us! Our customers hail from various sectors, encompassing
heavy equipment manufacturing, general commercial enterprises, and entities in industrial,
transportation, medical, and consumer realms, among others. While our clientele spans the globe,
reaching the United States, Europe, and beyond, they all share a common need for impeccably
machined parts, adhering to specifications, delivered promptly, and meeting budgetary considerations.
