What is CNC Machining Servie?
CNC machining service is a manufacturing process where computer-controlled machines precisely cut and shape metal, plastic, and other materials. Simply put, it uses automated, intelligent tools to accurately transform raw materials into the desired shapes and dimensions based on 3D design files.
You can think of it as a smart carving machine where the workpiece rotates or is fixed while cutting tools follow programmed paths at high speeds. This ensures not only fast production but also consistent precision and high quality for every part. CNC machining is widely used for producing complex custom components in industries such as automation equipment, aerospace, and robotics.
TiRapid supports everything from single prototype to small batch production, from micro machining to large machining.

Common Problems of Custom CNC Machining Parts
What are the minimum and maximum sizes you can machine?
We can machine holes as small as 0.2 mm and handle maximum workpiece dimensions up to 3000 × 2000 × 100 mm, the thinnest thickness is 0.5mm, accommodating a wide range of complex parts.
What is the quote turnaround time ?
Most quotes arrive in your inbox within 8 hours. For larger batch orders, we guarantee a full response within 24 hours.
Can you help design my product if I only have a sample?
Yes, we offer 3D scanning and free product design services. Whether your part is plastic or metal, we can assist you from sample to final design and production.
What is our fastest CNC machining lead time ?
For small CNC projects involving Al6061, We can achieve extraordinary results. Since we have in-house stock of this material, we can start and complete fabrication in as little as 2 days, ensuring your project keeps moving quickly without compromising quality.
Will anodizing affect the thickness of the product ?
In the world of anodizing, Type II is the standard variation. Clear coatings under Type II are typically 5 – 15 µm thick, while colored or tinted coatings are 10 – 25 µm thick. Type III anodizing, often referred to as “hard anodizing,” can be 20 – 80 µm thick. A useful design principle to remember is that 50% of the anodic coating is below the original surface and 50% is above it. For example, a 12 µm coating will add 6 µm to the part thickness, which is critical for precise design and assembly considerations.
What thread specification compatibility can be used ?
Our machining capabilities extend to a wide range of thread specifications. We expertly process ISO metric threads (e.g. M3, M6, etc.) as well as BSPT, BSP and UNF threads. This broad compatibility ensures that our machined parts can be seamlessly integrated into a wide range of components across a wide range of industries.
