Choosing a qualified CNC machining unit is different from choosing other general industrial item manufacturers. In the manufacturing and CNC machining industry, what a machining factory provides is a machining service according to customer requirements. They manufacture, process and manufacture machine parts, mechanical products according to your drawings or samples, there are no products in stock for you to buy.
We all know that a good supplier is one of the most important factors to success, but choosing a good outsourcing company is not easy. It is for those who have no experience outsourcing CNC machining services.
That is not to say that it is too difficult for you to find a reputable CNC machining unit in China, a professional CNC milling and turning unit.
All selections must be based on criteria. To make it easier for you to visualize, we would like to suggest you a few things that you need to consider before placing an order. Based on finding the answers to these questions, you will have a basis to make a decision to choose your CNC machining house.
1. How long has the company been in the CNC machining industry?
In general, the longer a company has been operating in the CNC machining industry, the more professional and competitive the company becomes in CNC machining services. If the company has been in the precision machining industry for more than 10 years, then it must have accumulated a lot of experience and knowledge in this field.
It must go through many different types of machining projects. This means that the company must be able to handle complex part machining projects and machining materials that require more brainpower.
And they can solve the difficult and unusual problems of various mechanical parts properly. So it is better to choose a company that has been in the precision machining industry for more than 10 years and let them do the machining work for you.
2. How is the company’s processing machinery capacity?
As a professional processor, the processing unit you are targeting must have real production capacity. Apart from people, factories and machines are the most visible elements.
The workshop must have the main CNC processing machines, such as CNC lathes, CNC milling machines, CNC machining centers, flat grinders, wire EDM machines, drilling machines, waterjet cutting machines… The machines can do most of the work operations of the machining processes.
Usually, the more advanced the machine (machines of big brands), the higher the processing capacity. Outsourcing to a company that can do most of the outsourcing work in a workshop is much more efficient than outsourcing to two jobs, just for one project, so you can save a lot of time and money. more effort.

3. How does the company control the quality of the processing?
Quality is everything, before placing an order; you should know how your processing unit controls the quality of its processing. Do they have modern measuring and testing (QC) equipment?
For the CNC machining industry, the must-have measuring and testing devices are CMM (Coordinate Measuring Machine), caliper, microcaliper, pin gauge, ruler, gauge, etc.
A qualified CNC machinist will control the quality from material inspection to final finished work piece inspection. They can provide you with material report, sample measurement and test report.
4. Does the outsourcing company have design capabilities?
CNC machining involves a lot of design work; it uses CNC machines to make machine parts and mechanical products according to your design. If the processing unit has the ability to design, it will be of great help to you when processing or improving the design for machining, it will also be much easier to exchange techniques with them.
When reviewing your drawings, they can quickly analyze your product’s machinability and give you suggestions on how to make the right design changes to better suit your usage needs. you or even provide design service for you. People who design and run programs like NX, PTC Creo, SolidWorks, Auto CAD also understand the limitations of reading a design drawing according to customer requirements and the needs of both design and machining.
5. Does the salesperson have a mechanical engineering background?
Sales staff who can speak English well, and have a good mechanical engineering background are the conditions that help bring in good sales for a CNC machining unit. A salesperson with a background as a mechanical engineer will save you a lot of time and energy completing your machining orders. They will provide a fast and reliable bridge between you and the contractor.
A salesperson with a mechanical engineering background can understand your design better, give you advice, and track down the manufacturing process efficiently. Your order will be executed very smoothly.
6. Is their CNC machining quote competitive?
If you are looking for a precision machining unit, perhaps the first two pieces of information about a quote that interest you the most are price and delivery time. Of course, we all know that the lower the price and the shorter the delivery time, the more competitive the quote. To keep profits consistent, a good outsourcing service provider will always deliver the most profit for their customers.
They will be updated with machining technology, to ensure very competitive price and good quality by optimizing production process and improving production efficiency. By choosing this type of CNC machining plant, you can have the quality and turnaround time you want and also be somewhat competitive in price.
7. How is their after-sale service?
After-sales service is very important, especially for custom CNC machining services. Machining details are made according to the drawings you design. If it is a batch processing order, in order to get the right parts, you can first ask the manufacturer to make one or several sample parts for you to check and evaluate the quality.
Sometimes, you may not be satisfied with your first prototype. You can absolutely request a second sample. If the sample is not eligible to pass and it is caused by the processing unit, at this point, are they willing to redo it for free or if you require some changes, and are they ready to assist you for until you get what you want? Your project will go much more smoothly if the outsourcing company is always enthusiastic to support.
CNC Machining in the Automotive Industry
We must first understand the CNC concept first. CNC- Computer Numerical Control ie computer numerical control, it refers to the automation of machine equipment by computer mechanisms that execute a pre-programmed cycle of operating instructions. Basically, CNC is in contrast to devices that are controlled manually by levers or hand wheels, or which are instinctively automatic using only a traditional cam mechanism.
CNC Machining in the Automotive Industry
Computer numerical control (CNC) systems have recently become very popular in the automotive sector. From molding similar parts and components to making unibody frames. CNC machines and tools are largely responsible for a large number of machine parts found in modern vehicles.
In fact, the carburetor housings, brake and brake components, shafts, bearing covers as well as the engine housings are all manufactured using CNC machines. Acrylic/PMMA machining for headlights, exterior lights as well as interior lights is another model of how numerically controlled machining is being used when components are made in the automotive sector.
In the automotive field, compared with electronic devices, computer numerical control equipment brings the following benefits:
It brings multi-axis linkage, to achieve interpolation processing according to complex profiles of the product to be machined.High precision to achieve product quality consistency.
A high degree of automation, a feature that ensures reduced human intervention and minimized manual labor costs.
Numerical control ensures that mechanical transmission in the automotive industry is structurally simple and productive in terms of production. High productivity, almost error free.
