CNC Machining Services

Are you looking for a reliable and quick-turn provider of CNC machining services? You’ve come to the right place! Using state-of-the-art CNC technologies, our unmatched team of machinists, engineers, and quality control experts works together to ensure your products are done right and shipped on time. At Mingguan, we’ve designed our ISO 9001: 2015 certified CNC manufacturing facility for rapid prototyping and low-volume production of a broad range of components. Our CNC machining services also complement our other manufacturing capabilities (like 3D printing and injection molding), providing you with an all-encompassing manufacturing solution. We produce simple and complex precision machined parts in a broad range of materials and surface finishes.

High Precision CNC Machined Parts

CNC machines can create a broad range of features and high-precision parts. For instance, CNC milling machines are ideal for producing cavities, angled shapes, holes, and slots. In contrast, CNC lathes are suitable for creating cylindrical shapes or parts that are symmetrical near their axis. Nevertheless, CNC milling and turning machines can achieve tolerances as tight as ±0.001mm. They are also compatible with a broad range of materials, including metals and plastics, so long as these materials are available in blocks. This is not the case with additive manufacturing technologies (like 3D printing), which are only compatible with plastics and a few metals.

#1 High-quality and reliable. 

We have highly trained engineers, machinists, and quality control experts capable of getting your product done right the first time. Our team of experts follows industry standards by using best-in-class software, state-of-the-art CNC technologies, and quality control tools to create customers’ parts. 

#2 Broad range of material options. 

We offer a wide range of material options, including metal parts (like aluminum, steel, stainless steel, brass, copper), plastic parts (like POM, PTFE, PC, PEEK, PET), and special alloys (like Kovar, Invar, Inconel, Titanium, Mocu). 

#3 World-class machine shop. 

We adhere strictly to several key industrial, quality, and environmental standards. For instance, our machine shop is ISO 9001:2015 certified for quality management systems, ISO 14001:2015 for environmental management systems, and ISO 13485:2016 certified to fabricate medical devices. 

#4 Cost-effective manufacturing services At Mingguan, 

we adhere strictly to the design for manufacturing (DFM) criteriaㅡwhich means we design parts and optimize designs for ease of manufacturing. This reduces our start-up, material, and feature costs, providing you with a cost-effective manufacturing service. 

#5 Fast manufacturing and delivery 

Not only do we get your products done right, but we are also located in southern China’s Greater Bay Area. We’re close to major shipping ports, allowing us to get your products to you swiftly. 

#6 Custom CNC machining 

We offer custom CNC machining services to our customers that want to replace obsolete parts, work with difficult materials, or manufacture parts with special requirements.
