CNC Machining

At LC Rapid, our precise, quick-turn, custom CNC machining services in China make parts from various certified metal and plastic materials. Our CNC services include milling, turning, wire EDM, and much more.

With advanced CNC machining centers and experienced employees, we offer the same high-quality parts and satisfactory services to large and small companies alike, from Fortune 500s to innovative start-ups.

Introduction of CNC Machining Services 

CNC (Computer Numerical Controlled) is an automated manufacturing process to remove materials from a simple plastic or metal block with a serial of cutting tools to make the custom CNC machined parts. Advanced software is used to control the high precision machining according to the required specification of the CAD (Computer Aided Design) model provided by the customer. The support from LC team of engineers will program the CNC machining center to create the final products with a high level of part complexity, and provide exceptional surface finishes. As a professional CNC machining solutions inc, we are continuously offering a cost-effective CNC custom machining whether you need prototypes, production orders or mold tools that are used for plastic injection molding or pressure die casting services.

This finishing option means the quickest turnaround. Sanding process can remove the visible cutting tool marks, sharp edges, and burring.


This is a process where abrasive material is sprayed onto a parts with the aid of compressed air. Blasting is used to remove surface imperfections and achieve a smooth, matte appearance.


We offer the Anodizing color or clear (type II) and Anodizing hard coat (type III).

Type II anodizing improves corrosion resistance and wear resistance, and increases surface hardness. It can also allows us to get different colors on parts, including black, gold, red, blue, and clear. The most commonly-used material is aluminum.

Type III anodizing creates a thicker layer, making it a suitable option for applications that require excellent durability and hardness.


This is a process to improve parts strength, wear resistance, lubricity and aesthetic effect. A wide variety of metals are available to be applied onto the part surface -nickle, copper, chrome, silver, gold, and etc.
