We possess the capability to CNC machine a wide array of parts,
ranging from uncomplicated
"as-machined" workholdings to intricate geometries. Our manufacturing facilities are well-equipped
with a diverse range of CNC mills and turning centers, and upon request, we can also incorporate
EDM and grinders into the process. We offer precision with tolerances reaching as tight as 0.05 mm
(0.0020 in), ensuring efficient lead times, and providing delivery options within just 1 business days.
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.
Common Materials | |
Name | Description |
Aluminum | High machinability and ductility, good strength-to-weight ratio. |
Stainless steel | High tensile strength, corrosion and temperature resistant. |
Mild steel | High machinability and weldability, high stiffness. |
Brass | Low friction, excellent electrical conductivity, golden appearance. |
Copper | Excellent thermal and electrical conductivity. |
Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
ABS | Common thermoplastic, impact resistant, easy to machine. |

POM | High stiffness, high accuracy, low friction, easy to machine. |
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. What kind of surface finishes does offer?
Our array of finishing services is diverse, allowing us to achieve
nearly any desired aesthetic and
tactile quality for your parts. From treatments for metals to texturing for plastic injection mold tools,
and from painting metal to plastic, we offer a comprehensive selection of finishes.
If you're interested in understanding how to specify the surface texture you have in mind, our blog
provides valuable insights.
2. Can my parts undergo passivation?
Passivation, a surface treatment altering the chemistry of specific
metals, is available as a service.
We offer passivation with the goal of improving corrosion protection, durability, cosmetic appeal,
and other desired attributes.
3. What measures are in place to ensure the quality of my parts?
Following the confirmation of your order, we initiate a thorough
Design for Manufacturing (DFM)
review to pinpoint any concerns that our engineers identify as potential factors affecting part quality.
Our quality assurance process encompasses:
Rigorous inspection and verification of all incoming materials through the utilization of various
testing equipment.
Completion of final inspection reports conducted prior to shipment.
Additionally, we provide the capability to share inspection data
with you in real-time, fostering a
collaborative environment where any emerging quality issues during production can be promptly
addressed.
4. What will be the import duty cost for my goods?
Determining the precise import duty amount is complex, as it
depends on several factors.
For customers in Australia, the recent CHAFTA regulations allow for a phased implementation of
duty-free imports.
Import duties vary widely across countries and hinge on the nature of the imported goods.
Most countries globally follow the international Harmonized System (HS) codes, providing a
systematic classification for nearly all commercial trade goods.
