How to find the right CNC machining supplier in China?

When searching for low costs CNC machining factories with fast turnaround times, you will certainly find a lot of Chinese CNC machining service providers. It has to be said that they are common choice for those companies looking to outsource their machining parts manufacturing. To clarify, outsourcing CNC machining to China is a crucial step for many product engineers, because few other countries can match China in terms of cost and efficiency.

However, to find the right supplier for CNC machining in China is often very difficult. There are a lot of Chinese CNC machining factories to choose from, and communication is in general more challenging than it is with local suppliers. In addition there are the differences in currency, quality standards, and intellectual property laws.

Furthermore, there are numerous websites such as Alibaba and Made-in-china, where you can find hundreds of suppliers.

Outsourcing CNC machining to a trustworthy supplier.

Companies all over the world, whether they are small or large, outsource at least a part of their components fabrication. For prototypes, pre-series and mass production, many companies choose to have their CNC machined parts made by a Chinese CNC machining company. Moreover, it does not make sense for small or medium-size companies, to invest in their own machinery. In addition, there is also the need of skilled programmers and operators, which are not always available.

Even CNC machining might be less of an art than manual machining, it still requires knowledge and lots of experience to have the machining job done in the right way.

Why outsourcing CNC machining to China?

In the last decades, Chinese machining factories adapted to mass production of high precision quality parts manufacturing. And, along the way they became experts in the field of component manufacturing. The Chinese factory output and export to the rest of the world is a proof of their success.

Still, China offers the most efficient and competitive manufacturing of components available today. In addition, upscaling of the machining capacity has driven the costs further down. And in most cases, because of the huge number of CNC machining factories in China, many factories use Chinese made CNC machines in combination with Western machinery. Furthermore, nothing can be compared to the large supply chain of raw materials, machine parts, cutting tools in China.

However, you have to be aware that every part makes sense to be manufactured in China. Simple parts, which are heavy, don’t have that much added value when being CNC machined in China. In addition, the shipping cost adds a lot to the unit cost. And, those shipping costs increased drastically in the last year.

There is a bigger advantage to outsource production of medium size series, where no automation is involved. Also, machined features which can be done by hand add to low cost. Think of deburring, chamfering, reaming, assembly.
