How to Select a Good CNC Machining Manufacturer?


Selecting a good CNC machining manufacturer is totally different from selecting ordinary industry factories. A CNC manufacturer offers the customized CNC machining service. They supply parts based on your drawing or sample. There will be no finished products in stock for a customer to purchase.


Choosing a great manufacturer means you are half way to success. However, it’s not easy to choose a good machining manufacturer, especially for those people who doesn’t know much about CNC machining services. Some things need to be taken into account before you place an order.



  1. 1.How long has a manufacturer been in the CNC machining industry?

Generally speaking, the longer time one manufacturer is in CNC machining, the more professional the manufacturer becomes. If the manufacturer has been running the precision machining business for over ten years, it should have accumulated a lot of experiences for the field. The manufacturer has the ability to cope with complex parts and materials that are difficult to be processed. Therefore, it’s better to choose a manufacturer who has been in the precision machining for over 10 years, because they have solutions for the encountered difficulties in the industry.



  1. 2.What kind of equipment does the factory have?

There should be the main CNC machines such as CNC machining centers, CNC milling machines, CNC lathe, W-EDM machines, drilling machines, tapping machines versatile internal and external grinding machines in the factory as a professional machining manufacturer. Most of the machining processes can be carried out by these machines. Usually, Normally, the more advanced the machine is, the better the machining capability becomes.



  1. 3.How is the factory’s machining quality control?

Quality means everything. You should learn how the factory’s machining quality control is before placing an order. Check if the factory has advanced measuring and testing facilities such as CMM (Coordinate Measuring Machine), projector, calipers, microcaliper, caliper gauge, pin gauge, pass meter, etc. From raw material selection to shipment, a qualified CNC machining manufacturer should check every process and provide material and testing reports for you.



  1. 4.Can the machining factory design very well?

CNC machining requires a great deal of designs and the part is manufactured based on the design. If the machining manufacturing plant has design ability, it’ll help to improve your machining design. The manufacturer can fast analyze the part’s machinability, and give you advice on making changes to better meet your requirements, or even offer the design service for you after reviewing your drawings. Machinists who uses SolidWorks, UG and Auto CAD are better. They know the constraints and needs of both design and machining.


  2. 5.Does the salesman knows about mechanical engineering?

The salesman who can not only speaks good English, but also knows mechanical engineering is great for a CNC machining factory. A salesman who knows mechanical engineer can save you much time and energy to get your parts done the way you want.



  1. 6.Is the quotation competitive?

The most important thing you concerned about is the price and lead time when it comes to looking for a machining manufacturer. The lower the price and the shorter the lead-time is, the more competitive the quotation becomes. A good machining manufacturer always let the customer have the most profit in order to have a proper profit. The manufacturer will work on the machining technology so as to make sure a competitive price and good quality by improving production processes and efficiency. You can obtain good quality, turnaround time and competitive price by selecting thid type of CNC machining manufacturer.



  1. 7.How is the after sale service?

After sale service is extremely vital, particularly for customized machining services. The machined part is formed based on the drawing. First, you need to ask the manufacturer for some samples so as to know the quality of the machined part. Sometimes, you may not get the proper part once and therefore you need to ask for another sample. If the sample is not good, the problem will be the machining manufacturer. At this time, is the manufacturer willing to do it again for free or change till you get what you want? The project will be more smooth if the machining manufacturer is willing to cooperate with you.



CNC machining service is an OEM service which needs a great deal of customized work. If you have a good CNC machining manufacturer, you will save time and money. On the contrary, if you have a bad manufacturer, you will have a lot of problems. You will have an idea on how to look for a good machining manufacturer after reading this article.
