CNC machining is one of the most common methods for manufacturing parts and products. Computer Numerical Control (CNC) uses highly automated processing to manufacture parts, which has advantages over many traditional manufacturing methods in terms of speed, productivity and accuracy. However, despite the low machining costs, there is often a temptation to try to save more. That is, customers provide materials themselves, thereby eliminating material costs. But providing the materials yourself may not be a good idea. Mainly because:
1. Material traceability
What is material traceability? Why is it so important? In the metal machining manufacturing industry, it is a responsibility to protect CNC machining manufacturers, buyers and sellers from defective products. In addition, tax credits, insurance, quality assurance, or environmental certification for new buildings require written proof. When purchasing materials from a reputable supplier, the materials are usually accompanied by a material certificate, if not, you can ask for it. We request the factory to send us the test report together with the materials. The material must also be labeled, and the heat can be traced back to the source of the material and the relevant mid-term review. Our process maintains this traceability. CNC machining parts are designed by using nationally or internationally defined material properties. If the materials actually used are not up to standard, the CNC machined parts may experience unexpected failures, which are far below the design range. Therefore, the traceability of substances is absolutely important.
2. Material quality
Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services meet their purpose.
With a trusted CNC machining partner, you can be sure that when the CNC machining workshop purchases materials, you will get the best materials. If you provide your own materials, the quality of the materials will not meet the standard. These guidelines, definitions and procedures help achieve the following goals:
1. Meet customer’s quality requirements
2. Ensure that CNC machining parts and services are safe
Compliance with regulations
1. Achieve environmental goals
2. Protect CNC machining parts from the influence of weather or other adverse conditions
3. Ensure that internal processes are defined and controlled
Summarize
Providing your own materials will bring more problems than solutions, and it is unlikely that you will get any financial benefits by providing your own materials. It is much more effective to hand over the purchase of materials to CNC machining shops because they know all the potential defects of the material supply and are more capable of managing risks. They have also established a procurement mechanism that simplifies the entire process.
