Precision mechanics manufacture parts with low tolerances using manual labor or computer numerical control technology. They may work on prototypes, custom parts, or assembly lines, requiring technical training and attention to detail. Interpersonal communication skills are also important for supervising workers and ensuring customer satisfaction.
A precision mechanic manufactures parts with very low tolerances for errors. The work can include a variety of products, from custom components for spacecraft to mass production of car parts. Careers in this field typically require formal apprenticeship or training at a technical school or college. It can take several years of education to be able to work independently as a precision machinist, and some continuing education may be needed to keep up with the industry.
Historically, machining involved manual labor to create components. Today, a precision mechanic can perform tasks with the aid of computer numerical control (CNC) technology. Handcrafting requires focused, patient attention on the part to ensure it is machined to customer-defined specifications. To operate a CNC machine, the mechanic needs to understand programming and be able to tell the machine how to process the component.
Some precision machinists work on prototypes. As the project progresses, the team can order machined parts to assemble prototypes for testing. Once the design is complete, a precision mechanic can be involved in programming CNC equipment for mass production. The mechanic starts with the final prototype, refining the design and features to make it possible to produce a large number of identical parts.
These workers can produce custom parts. Some work in facilities such as aerospace companies, while others may contract with multiple clients. The customer provides information about the part and the need to allow the mechanic to select the best materials and successfully manufacture the part. These custom parts can be manufactured in very short runs. A precision mechanic needs an intimate understanding of the part as well as the application to ensure the customer receives the best possible end product.
A precision machinist can also be responsible for an assembly or production line. The machinist programs and checks equipment, performs on-site quality control checks, and supervises workers on the line. Every part that comes off the line needs to be within a strict set of specifications, which demands attention and focus from the mechanic who monitors the process. In this role, it is important not only to understand machining, but also to have interpersonal communication skills. The mechanic can act as a conduit between workers, supervisors, customers and other teams to ensure parts are produced properly and as expected.
