The most suitable application for CNC machining lies in one-off manufacturing endeavors and in
low-to-medium volume production scenarios, typically ranging from several hundred to 1000 parts.
Opting for CNC machining is particularly advantageous when aiming for cost-competitive metal
prototypes.
Additionally, the technology shines in situations where the parts necessitate extremely tight
tolerances for precision.
Product Details
CNC machining can be used for a wide variety of materials, with the most common being
aluminum, steel, brass, ABS, Delrin, and nylon. But really, almost any hard material can be
CNC machined.
| 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. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
| 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.

Specialist Industries
CNC turning services stand at the forefront of various industries, particularly in the transportation
sector encompassing aerospace, automotive, mass transit, rail and locomotive, military, and
trucking.
These services are integral to the creation of transportation equipment, including headnuts, gear
blanks, bearing blocks, levers, axles, and rotors, utilizing the precision of CNC machines.
In the construction industry, CNC turning is employed to manufacture robust bolts and screws from
materials like stainless steel and aluminum, catering to the demanding requirements of heavy-duty
applications.
Additionally, CNC turning services contribute significantly to the automotive sector, producing
essential components such as cylinder heads, connecting rods, camshafts, shafts, rings, sway bars,
control arms, tie rod ends, bushings, and bolts.
The aviation industry, known for its exacting standards, relies on CNC turned parts for probes, joint
connectors, fasteners, and engine and aircraft components, often opting for titanium due to its
resilience in extreme temperature conditions.

FAQ's
1. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In the absence of a specified fillet radius in the 3D model or drawing, the machinist will add
fillet radii based on discretion to facilitate easy machining. Should a specific fillet radius be
required, clear specification is essential.
As a general guideline, internal vertical edge radii might exceed 1/3 of the depth, while
internal horizontal edges may either be left sharp or feature a radius ranging from 0.5mm
to 1mm.
2. What is your typical lead time? Can my parts be produced on a rush basis?
Our standard lead time for screw machine products, encompassing quoting, manufacturing,
and shipping, is typically around one week. With an on-time delivery rate exceeding 99%,
we prioritize efficiency. Depending on factors like tooling, gauges, and material availability,
we may have the capability to produce your parts on an expedited basis. Feel free to inquire!
3. Can I use my own material for production?
Absolutely, you can use your own material for production, as long as it aligns with the capabilities
of our machines.
4. How does compare to other suppliers on price?
While direct comparisons can be challenging, generally, We offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers
in North America and Europe.
