The essence of CNC machining, or Computer Numerical Control machining, lies in its subtractive
manufacturing approach, automatically eliminating material from raw stock based on computer
-generated instructions. Typically, CNC machines fall into two categories: those that maintain the
raw stock in a fixed position while rotating the cutting tool, and those that rotate the raw stock
while maneuvering it against a stationary tool.
Numerous adaptations and hybrid methods exist, enabling certain machines to utilize both
techniques concurrently, facilitating the production of parts with complex features.
Product Details
The choice of raw material directly impacts machining costs.
Different materials have varying costs, availability, and machining characteristics.
High-performance alloys may be more expensive than common metals.
Material availability affects pricing, and considering material type is essential for cost calculation.
Here is a comprehensive overview of the most popular materials.

FAQ's
1. 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.
2. What type of surface finishes does provide?
We provide an extensive range of finishing services to achieve virtually any desired look and feel for
your parts. Our offerings include treatments for metal, texturing for plastic injection mold tools,
painting for both metal and plastic, and a variety of other options. Learn more about specifying the
surface texture you desire in our blog.
3. Can passivate my parts?
Passivation is a treatment that alters the surface chemistry of certain types of metals. We provide
passivation services for corrosion protection, enhanced durability, improved aesthetics, and more.
4. How much import duty will I need to pay for my goods?
The specific import duty for your goods varies, and there isn't a one-size-fits-all answer.
For customers in Australia, new CHAFTA regulations enable a gradual implementation of duty-free
imports.
Import duties are diverse and contingent on the type of goods being imported. Globally, most
countries adhere to international Harmonized System (HS) codes, categorizing almost all commercial
trade goods.
