Application of CNC Milling Parts
CNC milling stands as a cornerstone in manufacturing, offering efficiency, precision, and the
elimination of manual labor. Machine shops play a critical role in providing essential services for
prototypes and full production runs.
The electronics industry heavily relies on CNC machines to manufacture components like electronic
enclosures and circuit supports. In the commercial sector, CNC cutting heads contribute to the
cost-effective production of various parts, aiding companies in reducing production costs and saving
time.
The oil and gas industry utilizes CNC machines extensively for the production of components such
as drill bits, cylinders, pins, rods, and valves. The medical industry benefits from CNC milling in
creating a wide range of components, from implants to medical devices. The aerospace industry,
with its constant need for precision, embraces CNC machined parts for crafting complex and
customized components integral to aerospace equipment.

FAQ's
1. The cost of CNC machining a part is shaped by a variety of factors, including:
1. Material: Material selection introduces cost variations, with materials like aluminum being
more economical to machine compared to others like Inconel, attributed to factors such as tool
wear and cutting speeds.
2. Complexity: Parts featuring intricate designs incur higher machining costs.
The complexity of surface shapes, for instance, significantly influences overall machining expenses.
3. Tolerances: The precision demanded by dimensional tolerances impacts CNC machining costs.
Imposing overly tight tolerances on non-critical features can lead to unnecessary cost escalation.
4. Surface Finish: Achieving mirror finishes demands specialized tools and machining strategies,
extending machining time and, consequently, increasing costs.
5. Quantity: Production volume is a key determinant of costs. Low-volume production tends to be
costlier per part, as initial setup and programming costs are distributed over a smaller production run.
2. Machined Parts Precision and Finish Guidelines:
Our machined parts adhere to precision standards, featuring +.005”/- .005” local tolerances across
most metal geometries and +/- 0.010" for plastics. It's worth noting that tolerances may vary for
larger parts, especially with considerations for flatness post heat treatment.
An "As Milled" finish for CNC parts requires a minimum surface finish of 125. Fabricated parts
maintain a 0.010” dimensional tolerance and a 1° angular tolerance. Tapped holes not explicitly
labeled as features in the CAD model may be machined based on the specified diameters.
Crucially, surface treatments such as anodizing, bead blasting, iriditing, powder coating, etc.,
will only be applied upon explicit payment and acknowledgment.
3. How much import duty will I need to pay for my goods?
The amount of import duty for your goods is not standardized and varies based on several factors.
In Australia, the introduction of new CHAFTA regulations allows for a progressive implementation
of duty-free imports. Import duties differ widely and are determined by the type of goods being
imported. Globally, most countries adhere to international Harmonized System (HS) codes, which
categorize nearly all commercial trade goods.
