The Production Process
KDM has strict working procedures to meet quality and standard requirements, our CNC machining process includes the following steps:
- Review your 2D/3D drawings and give you a quote
- Select and inspect the raw materials(metal or plastic, based on your needs)
- Using CAM to convert your design into the workpiece
- Turning, milling, or routing through high-precision machines
- Remove sharp edges and apply surface finish (anodizing, polishing, etc.)
- Check the details, pack the products, and deliver them worldwide
Surface Finish Options
We can provide you with various surface finish options, whether you want a nice appearance or strong protection, we will get the right solution for you.
- For appearance: anodizing, polishing, sandblasting
- For protection: powder coating, plating, brushing
All finishes are applied with professional precision. Choose the finish fits for your product, or tell us your idea, so that we can recommend the most suitable one for you.

Custom CNC Machining Parts by Processing Method
Machining is a process of shaping metal or plastic raw materials into parts by removing material. At KDM, we offer you three processes: Turning, Milling, and Routing. Each has its own advantages depending on the part shape, material, and complexity.

Turning is ideal for producing shafts, rods, bushings, rings, and other cylindrical parts. The cutting tool removes material while the workpiece rotates, resulting in an excellent surface finish and high dimensional accuracy.

Milling is a process of removing material by rotating a tool and moving it on the fixed part. It is suitable for machining flat surfaces, slots, holes, and even complex 3D shapes. If you need metal and plastic part machining, you can choose this.

Routing is very similar to milling, but at KDM, it generally uses high-speed rotating tools to cut complex shapes and patterns, and is mainly used for softer materials such as wood, plastic, and foam. If you are engaged in sign making, advertising, and sample development, routing may be your choice.
CNC machining utilizes a computer to control tools, making it ideal for complex shapes, tight tolerances, and large batch production.
Traditional machining, on the other hand, relies on manual operation. It is suitable for low-volume production and easy operation.
Generally, the tolerance of CNC machining parts is ±0.05 mm, but we can achieve ±0.001 mm if you require high-precision products. It depends on your drawings or ideas.
Normally, samples take 3-5 days, and mass production takes 7-20 days.
Surely! If you need parts urgently, KDM also has the expedited option. Contact our customer
service, we will deliver them as soon as possible.
We provide a quality guarantee for all CNC machining parts. If there are any quality issues within 12 months, we will remake or refund accordingly.
100% inspection during production. We have certifications including ISO 9001:2015, ISO 13485, IATF 16949, AS 9100, etc.
