Precision in Every Part, Excellence in Every Detail
Add to Cart
Custom CNC machining is a widely adopted subtractive manufacturing technology renowned for
its excellence in crafting bespoke metal and plastic components tailored for both prototyping
and production needs.
By harnessing CAD (computer-aided design) modeling software in conjunction with G-code,
CNC milling and CNC turning machines proficiently remove material from solid workpieces with
exceptional precision and speed.
CNC machines are adept at producing durable parts characterized by stringent tolerances and a
diverse range of outstanding material properties, both mechanical and chemical in nature.
Our bespoke CNC machining service is ideally suited for singular projects and medium-volume
production runs, capitalizing on automation and a high degree of reproducibility.
Product Details
CNC machining encompasses a wide range of materials, with three main categories:
plastics, soft metals, and hard metals. These materials are versatile and suitable for various
machining applications.
Examples of materials used in CNC milling include aluminum, bronze, copper, ceramics, plywood,
various types of steel, stone, wood, and zinc, among others.
Certain materials, such as aluminum and mild steel, are favored by machinists due to their ease
of workability and excellent properties, making them industry standards for many applications.
| 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.

FAQ's
1. Can you create design drawings for me?
While we do not offer standalone product design services, we do provide Design for
Manufacturing (DFM) reviews for all approved orders.
This means we collaborate with our clients to optimize their 2D and 3D drawings, enhancing
manufacturability, resolving design issues, and reducing production expenses.
Learn more about preparing your CAD drawings for manufacturing.
2. How long does it take to receive a quotation?
Typically, we aim to respond to your Request for Quotation (RFQ) within one days after
receiving it. If there is any unexpected delay in providing the quote, we will promptly notify
you of the revised timeline.
3. Is it possible to provide my own material for production?
Certainly, we accept customer-supplied materials as long as they are compatible with our
machine capabilities.
4. How can I ensure the confidentiality of my design?
Rest assured, we are committed to maintaining the confidentiality of your designs.
We are more than willing to sign and uphold any non-disclosure or confidentiality agreement
you require.
Furthermore, our factory strictly enforces a "no photographs" policy for any customer's product
without explicit permission. Our reputation is built on years of experience, working with
countless unique designs, and safeguarding proprietary information from third-party disclosure.
Your design's confidentiality is our priority.
