Product Details
Materials Commonly Used in CNC Machining
CNC milling 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. |

FAQ's
1. Can make design drawings for me?
We do not offer standalone product design services, but we do provide Design for Manufacturing
(DFM) reviews for all approved orders.
This means that 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 a quotation take?
Typically, we aim to provide a response within one days upon receiving an RFQ. If there is a delay
in generating the quote, we will promptly inform you.
3. What's the general surface texture of CNC milled and turned parts?
In the realm of CNC machining, as-machined milled parts typically exhibit a surface roughness of
approximately 3.2μm (or 1.6μm in the case of relatively new machines). On the other hand, when
it comes to turned parts, we can achieve a smoother surface with a roughness of 0.8μm.
This means that machining speed adjustments are not necessary to attain this level of surface finish.
4. What are your tolerances for machined parts?
Our tolerances for machined parts are typically within +0.005"/-0.005" for most metal geometries,
and within +/- 0.010" for plastics. However, tolerances may vary for larger parts, especially when
maintaining flatness over extensive sections post-heat treatment.
Regarding the finish requirements, an "As Milled" finish should have a minimum of 125 surface finish
for CNC parts.
For all fabricated parts, there is a dimensional tolerance of 0.010" and an angular tolerance of 1°.
Please note that tapped holes not explicitly indicated as features in the provided CAD model may be
machined to the specified diameters in that model.
Additionally, surface treatments like anodizing, bead blasting, iriditing, powder coating, etc., will only
be applied if they have been paid for and explicitly acknowledged in advance.
