In traditional machining, a skilled machinist manually operates a machine to remove or shape
metal based on specifications provided by designers and engineers, typically conveyed through
an engineering drawing or blueprint.
This process involves the use of turn wheels, dials, switches, chucks, vices, and various cutting
tools made of materials such as hardened steel, carbide, and industrial diamond.
Measurement instruments are then utilized to ensure the accuracy of all dimensions.
In contrast to this manual approach, CNC machining performs the same metal cutting, drilling,
milling, boring, grinding, and other metal forming and removal functions, but it relies on
computer numerical control instead of manual operation by a machinist.
It is automated, driven by code, and developed by programmers, offering precision consistently
from the first cut to the 500th. While traditional machining still has a place, CNC machining,
prevalent in digital manufacturing and low-volume production, allows for easy revisions and
alterations for modifications and different materials.

Typical Applications of CNC Turning
The applications of CNC machining are virtually limitless, offering a myriad of possibilities across
various industries. One notable application is in the woodworking sector, where CNC machines
streamline the production of wooden furniture, saving time and reducing costs.
Complex geometries that would traditionally require a skilled woodworker can now be achieved
efficiently through CNC machining. In lettering and engraving systems, CNC technology is utilized
for marking patterns or text onto surfaces, serving both artistic and serialized part needs.
The electrical industry benefits from CNC machining for tasks such as creating component
mounting holes in printed circuit boards and machining heat sinks for heat-generating electrical
components.
Precision equipment for the pharmaceutical industry, including metering pumps, ingredient
-dispensing nozzles, and packaging components, is also manufactured using CNC machines.
Even in the fast-moving consumer goods sector, CNC machining plays a vital role in producing
custom material-handling machinery for the food and beverage industry, as well as contributing
to the fabrication of injection-molded plastic molds used in food packaging.

thorough Design for Manufacturing reviews for all approved orders.
Our collaborative approach involves assisting clients in refining their 2D and 3D drawings to
enhance manufacturability, resolve design conflicts, and cut down on production costs.
Explore our recommendations for preparing CAD drawings for manufacturing.
2. How much import duty will I need to pay for my goods?
The import duty for your goods is not universally fixed, and its calculation depends on several
factors. In Australia, new CHAFTA regulations facilitate a phased introduction of duty-free imports.
Import duties vary widely and are contingent upon the nature of the imported goods.
Internationally, the majority of countries follow the Harmonized System (HS) codes, classifying a
broad spectrum of commercial trade goods.
3. Do you offer reverse engineering services or suggest cost saving measures?
In addition to providing reverse engineering services, we excel in extracting design and
engineering details from diverse manufactured components. Our support extends to assisting in
the design process, recommending optimal raw materials, and advising on efficient machining and
finishing strategies.
