In many different industries from parts and components for firearms to robotics and medical devices, precision is critical. Not only is precision important for the functioning of the device or system, but it is also required for safety, long life cycles and perhaps even for life-saving technology.
The best companies that specialize in precision machined parts understand the importance of quality control the production of the final component. They see this as not just a certificate or an ideal that represents the company publically, but rather as the central and driving force throughout the production process.
Training and Certification
When the company is focused on manufacturing precision machined parts, there is a focus on training of the staff in quality control. Most of these top companies will move forward with ISO 9001 certification, which is specific to developing a company-wide approach to quality.
Additionally, companies producing medical devices and orthopedic or dental implants will also have ISO 13485 certification, which is specific to medical device production. A few companies may also have additional certification, including AS9001C. This is granted by the NSF-ISR and applies specifically to the production of aviation, space and defense quality management system certification.
Bottom Up Quality Control
A unique approach to quality control offered by the best companies manufacturing precision machined parts is the bottom-up, company-wide quality control system. This means that everyone in the company is focused on quality control and is aware of the appropriate inspections and requirements that are in place.
This allows each employee to be responsible for quality management, rather than depending on line managers or final product inspection to detect a problem. With this continual observation by employees combined with CNC equipment and continual data collection, the process is maintained to the quality standards set by the company.
