CNC machining represents the predominant subtractive manufacturing technology in today's industry,
providing an exceptionally versatile and robust method for crafting personalized metal and plastic parts.
Utilizing CAD models, CNC machines precisely eliminate material from solid blocks using various cutting
tools.
Product Details
The primary focus of the CNC machining process revolves around metals, incorporating alloy steel,
carbon steel, cast iron, stainless steel, aluminum, copper, magnesium, and zinc.
Nevertheless, CNC machining extends its capabilities beyond metals to encompass plastic parts
and other materials, including ceramics, composites, thermoplastics, and thermosets.
| 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 machines showcase their versatility by crafting an array of parts with varying
intricacies. Among the parts manufactured are shafts and axles, ideal for industries like automotive
and aerospace.
Additionally, CNC turning is adept at producing precision bushings and bearings crucial for reducing
friction in mechanical assemblies. The scope extends to connectors, fittings, fasteners such as
screws and nuts, as well as valves and valve components.
Furthermore, CNC turning plays a pivotal role in creating tooling components like inserts, toolholders,
and bodies, contributing to enhanced efficiency and accuracy in machining operations.
In the automotive sector, CNC turning is harnessed for crafting engine components, pulleys, brackets,
and specialized parts.

FAQ's
1. 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.
Our approach considers the end-use of the part, enabling us to pinpoint subtle design
modifications, material alterations, or tolerance adjustments that can lead to cost savings without
sacrificing quality or performance.
2. How long does delivery time and quotation take?
The delivery time for parts is intricately tied to their complexity. Low-complexity parts usually have
a lead time of 2-3 days, while moderate complexity extends to 2-5 days. High-complexity parts may
necessitate a lead time ranging between 5 and 15 days.
Quoting time is also linked to design complexity, ranging from 1 business day or faster for simpler
designs to 3+ business days for more intricate ones. If you have a design that requires assessment
and quoting, do not hesitate to contact our team.
3. 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.
4. Can passivate my parts?
Passivation is a surface treatment that modifies the chemistry of specific metals. Our services
include passivation for purposes such as corrosion protection, increased durability, and enhanced
cosmetic appearance.
