plastic and metal CNC prototype

CNC Prototyping for Verification and Testing

Prototyping as a stage in product manufacture and release makes design verification and testing for functionality easier. At XinCheng, we sometimes employ CNC prototyping when developing your prototypes, thus reducing time to market while ensuring the product is functional.

small batch machined parts

CNC Machining for Low-Volume Production

Low-volume CNC machining is ideal for custom machined products to accelerate the product development process. It serves as a bridge between prototyping and full-scale production while also reducing production costs.

Tolerance of CNC Machining Parts

We create CNC machining prototypes and parts with high precision and accuracy. While we have standard tolerances for metals and plastics, our flexibility lets us work with your desired tolerance as long as you indicate it in your design drawing.

Available Surface Finishes Options for CNC Machined Parts

After the CNC machining process, machine marks are often visible on the surface of produced parts. Applying surface finish to custom parts helps improve part aesthetics and functionality. At XinCheng, we offer various surface finishing options for your CNC machining projects.

As Machined
machined surface

As Machined

This finish leaves the surface as-machined, with little or no alterations. What we do is that we deburr the surface and chamfer sharp edges. This type of surface finish works with most CNC machining materials. You can also opt for smooth machining or fine machining. Choosing these alternatives means less evident machining marks on the surface of your part due to the use of sharper tools and a lower feed rate.

anodizing parts with different colors


Anodizing as a metal surface finish option improves a product or part’s wear and corrosion resistance. It also improves hardness while protecting the CNC part surface. This surface finish has many applications such as the automobile and aerospace industry.

machined parts with electroplating


This process is quite popular and has a wide range of adoption. It involves coating the surface of a part with another material. The aim here could be decorative or functional. Aluminum, steel, and stainless steel are ideal candidates for electroplating.

polished machined parts


This involves manually polishing the surface of a part in multiple directions. Polishing creates a smooth and shiny surface that is often reflective. Polishing is ideal for metal materials, including PMMA, PC, stainless steel, aluminum, and steel.

Powder Coating
powder coating process

Powder Coating

This is a strong finish that is wear resistant. The coating is applied as a free-flowing dry powder and electrostatically for this finish. Curing occurs under UV light or heat. Besides, powder coating is an excellent surface finish for metals like stainless steel, steel, and aluminum.

brushed finish


Brushing involves rubbing the surface of a CNC machined part with #400-600 grit sandpaper. The aim here is to reduce machine marks and surface roughness. Materials you can brush include; aluminum, stainless steel, ABS, and steel.

CNC Machining FAQs

CNC is a subtractive manufacturing process. In other words, this machining involves removing materials from a feedstock until it achieves its final form.
Additionally, CNC machining is unique and versatile, as it facilitates the production of parts using various materials, including metals, plastic, wood, foam, composite materials, and glass.

CNC services are common in the aerospace, consumer electronics, agriculture, robotics, automotive industry, and other metal parts fields.

CNC services facilitate rapid prototyping and fast full-scale production. It also offers manufacturers high accuracy, precision, and tight tolerances when making parts. Its wide range of material and finishing options is another advantage.

At XinCheng, we take your order seriously and give it special attention. Upon receiving your order, we analyze your CAD files and propose the most cost-effective machining solution according to your needs. The factors we consider are geometry, fit, tolerance, surface, and material. This helps ensure you get high-quality products or parts at the right time and at the best price.

The longer it takes to machine a part, the more expensive the process becomes. So, how do you reduce costs? Design features that are easy and quick to machine them. You can do this by reducing cavity depth, choosing the correct radii, increasing wall thickness, etc.
Additionally, consider using tolerances only when necessary, removing texts and lettering, and avoiding several surface finishes.
