CNC machining operates on subtractive processes, where the feedstock is machined to its final
form through the removal of material. This includes activities such as drilling holes, boring lots
and pathways, and shaping metal stock into new material with varying tapers, diameters, and
shapes.
In contrast to additive manufacturing methods that involve the addition, layering, and
deformation of materials to achieve a specified shape, CNC machining achieves shapes by
subtracting material. This distinction also separates it from injection molding, where material is
injected in a different state of matter using a mold and formed to a specified shape.

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.

Company Profile
FAQ's
1. 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.
2. 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.
3. 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.
4. What are you shipping terms?
Our standard shipping terms are Ex Works (EXW) for both rapid prototyping and regular production
orders. This implies that once the goods have left our premises, the customer assumes responsibility
for shipping, customs clearance, and all associated fees.
For express shipments, we employ Delivered Duty Unpaid (DDU), where the client is accountable
for paying import duty upon the arrival of the goods at the destination.
