Titanium Machining Parts
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 encompasses a wide variety of materials, each
requiring specific machining
parameters for optimal performance. The most common materials
include:
1. Metal:
Metal is the predominant material in CNC machining, with the
ability to cut various types, from
brass to nickel superalloys like Inconel. Applications range from
injection molds to shafts and gears.
2. Plastic:
While injection molding is common for plastic parts, CNC machining
is used for specific components
like ABS, nylon, and polycarbonate. Applications include valve
bodies, bushings, and injection
molding prototypes.
3. Wood:
CNC routers are frequently employed for wood cutting, especially
for decorative purposes like
furniture, window frames, and ornamental panels.
4. Foam:
Polyurethane foam, both closed and open-cell, finds application in
CNC machining for creating
secure packaging, such as foam used in toolboxes for tool
transportation.
5. Composites:
CNC machines are essential for processing abrasive composite
materials like aramid, fiberglass,
and carbon fiber, commonly used in aerospace and marine components.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit
visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques
aimed at enhancing the surface
appearance and elevating attributes such as wear resistance,
corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present
viable options for refining the
final presentation of your custom parts, allowing you to achieve the
desired surface quality and
performance characteristics.

FAQ's
1. How do I know my design will be kept confidential?
Rest assured, we are committed to maintaining the confidentiality
of your design.
We are willing to sign and uphold any non-disclosure or
confidentiality agreement.
Additionally, our factory strictly prohibits the taking of
photographs of a customer's product
without explicit permission. Ultimately, our reputation is built on years
of working with
numerous unique designs, ensuring that no proprietary information is ever disclosed
to
third parties.
2. How does you ensure the quality of my parts?
Upon confirmation of your order, a comprehensive Design for
Manufacturing (DFM) review is
conducted to identify any potential issues that could impact the
quality of your parts.
All incoming materials undergo thorough inspection and verification
using a suite of testing
equipment.
Final inspection reports are generated before shipment.
Additionally, we offer real-time sharing
of inspection data, fostering collaboration to address any quality
concerns that may arise during
production.
3. What cosmetic standards do you guarantee?
Our commitment to quality includes standard deburring and
edge-breaking procedures for all CNC
machined parts. Any critical edges requiring a sharp finish must be
explicitly indicated in technical
drawings.
Surfaces are guaranteed to be free of defects such as scratches,
dents, stains, blemishes, hanging
marks, and minor imperfections. Critical surfaces (primary (a)
side, as specified in technical
drawings) will be void of mill steps and other marks.
For the secondary (b) side, minor hanging marks and up to 2 minor
defects are deemed acceptable.
To enhance surface roughness, visual properties, and wear
resistance, various post-processing and
finishing methods can be applied to CNC machined parts.
4. How much does CNC machining cost?
The cost of CNC machining is influenced by factors such as
complexity, quantity, and lead time.
To obtain an accurate quote, we encourage you to submit a 3D CAD
model, allowing us to provide
an interactive quote with design for manufacturability (DFM)
feedback.
Leveraging proprietary software and automated fixturing processes,
we eliminate upfront
non-recurring engineering (NRE) costs. This makes CNC machining
cost-effective for quantities as
low as 1 to 200 parts. While prices may compare similarly or
slightly higher than 3D printing,
CNC machining offers superior material properties and surface
finishes.
