Custom OEM precision CNC milling, turning, drilling anodized
aluminum machined parts
Before commencing drilling operations, it is of great significance
to consider a facility’s capabilities carefully. Productivity,
drill availability,
thread formation, and material properties may vary widely in CNC
drilling operations. The feasibility and efficiency of production
also depend in large part on the level of expertise of machinists.
Drilling refers to a cutting process in which the tool is moved,
the center of the tool is aligned with the center of the hole, and
the tool is rotated without the workpiece moving. CNC drilling is
mainly performed on CNC machines, including CNC mills and lathes.
CNC drilling is typically used in the creation and modification of
round holes, machine screws, and bolts. Drilling can process parts
in hard plastics, metals, wood, and the majority of other rigid
materials.
Our certifications
We have a complete set of systems to control production efficiency
and quality control processes,also,we have extensive project
management capabilities.
The main procedures of the CNC drilling process include:
CAD and CAM software translates the design schematics into computer
code for use with CNC machines.
|
The computer or controller uses this code as an instruction to the
machine when designated material is loaded into the drill press
table or clamped in a press vice.
|
The operator initiates the drilling process through the control
interface or panel.
|
A series of commands are executed in sequence to make holes or
threads of accurate and precise spacing, depth, and diameter.
|
While the process is automated, trained machinists are expected to
supervise the operation and perform regular maintenance on the
computer system and the drill to ensure consistent accuracy and
longevity of the product.

OEM CNC milling is the process of cutting and drilling a material,
such as wood or metal. Whether operated manually or via CNC,
milling machines use a rotating cylindrical tool called a milling
cutter. It is fixed to the spindle and can change shape and size.
The main difference between a milling machine and any other
drilling machine is the ability to cut at different angles and move
along different axes.
Aluminum is ideal for anodizing, anodized aluminum has an
attractive, minimal maintenance, highly durable appearance, and it
has a highly ordered porous structure that allows for secondary
processing, such as coloring and sealing. As a result, anodizing
has made aluminum one of the most respected and widely used
materials in the production of thousands of consumer, commercial
and industrial products today. Anodizing is available in countless
colors, including red, green, blue, gold, black, silver, and more.
- Precision Control: CNC turning offers high precision and repeatability because the
cutting movements are precisely controlled by the CNC machine. This
allows for tight tolerances and consistent part quality.
- Tool Changes: In some cases, multiple tools may be required to complete a part.
The CNC machine can automatically change tools as needed during the
machining process, reducing downtime and increasing efficiency.
- Finishing Operations: After the rough machining is completed, additional operations
such as threading, grooving, or chamfering may be performed to
achieve the desired final shape and surface finish.
- Quality Inspection: Once the part is machined, it undergoes quality inspection to
ensure it meets the specified tolerances and quality standards.

FAQs:
What is the difference between CNC machining and precision
machining?
CNC machining refers to the automated control of machining tools
via computer programs, whereas precision machining focuses on
achieving highly tight tolerances and high accuracy in
manufacturing parts.
How accurate is CNC machining?
CNC machining can achieve tolerances as tight as ±0.001 inches
(±0.025 mm) or better. However, it heavily depends on the machine’s
capabilities and the workpiece material type.
What are the types of CNC precision machines?
The common types of CNC precision machines include CNC milling
machines, lathes, routers, EDMs, plasma cutters, CNC laser cutters,
and grinders.
What is CNC precision machining used for?
NC precision machining manufactures high-accuracy components in
various industries, including aerospace, automotive, medical,
electronics, and defense—for instance, vehicle engine parts,
surgical instruments, electronic housings, and custom prototypes.
Is CNC precision machining expensive?
Due to its advanced technology and high accuracy, it can be
relatively expensive compared to traditional machining methods.
However, the long-run product reduces the per-part cost due to
manufacturing speed and efficiency.
