CNC Custom Made Parts CNC Turning Aluminium Parts CNC Machining
Center Service
While traditional machining involves a skilled machinist manually
operating a machine to remove
or shape metal based on specifications from designers and
engineers, CNC machining performs
the same metal cutting, drilling, milling, boring, grinding, and
other metal forming and removal
functions with a crucial distinction — it employs computer
numerical control rather than manual
operation.
Traditional machining relies on tools such as turn wheels, dials,
switches, chucks, vices, and
cutting tools made of materials like hardened steel, carbide, and
industrial diamond.
Measurements are taken to ensure accuracy. In contrast, CNC
machining is automated and
code-driven, developed by programmers. It delivers consistent
precision from the initial cut to
subsequent repetitions, making it suitable for digital
manufacturing and low-volume production.
CNC machining's advantage lies in its flexibility for revisions and
alterations, accommodating
modifications and different materials with ease. While traditional
machining retains its place,
CNC machining has largely taken over in manufacturing, fabrication,
and industrial production due
to its superior precision and automation.
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. |

FAQ's
1. What size of fillets are added when no specific fillet is
specified by the 3D model
or drawing?
When no specific fillet radius is outlined in the 3D model or
drawing, the machinist will incorporate
fillet radii at their discretion to optimize for easy machining. In
instances where a particular fillet
radius is needed, explicit specification is encouraged. As a rule
of thumb, consider internal vertical
edge radii exceeding 1/3 of the depth, while internal horizontal
edges may either remain sharp or
be introduced with a radius ranging from 0.5mm to 1mm.
2. What industries do you typically work in? Who are your typical
customers?
It's hard to find an industry we haven't collaborated with! Our
clientele represents diverse sectors,
including heavy equipment manufacturing, general commercial
enterprises, and businesses in
industrial, transportation, medical, and consumer domains, among
others.
Our customer base extends across the United States, Europe, and
beyond. What unites them is
a shared requirement for precision-machined parts delivered on time
and within budget constraints.
3. What is your typical lead time? Can my parts be produced on a
rush basis?
For screw machine products, our usual lead time—covering quoting,
manufacturing, and shipping
—is approximately one week, with an impressive on-time delivery
rate surpassing 99%.
Depending on various factors such as tooling, gauges, and material
availability, there's potential to
expedite the production of your parts. Just let us know your
