Advancements in technology have led to an increase in precision machining jobs, especially those linked to Computer Numerical Control (CNC) machining. This specialized field focuses on creating intricate and specific parts that fit into various devices or machinery where a standard part would not work. Precision machining has incredibly high standards, with tolerances often within thousandths of an inch. So, let’s explore precision machining jobs, what they entail, and why they are instrumental in today’s CNC industry.
What is CNC Machining?
CNC is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.
What is Precision Machining?
Precision machining is a type of technical manufacturing employed in the creation and design of complex parts and machinery. The use of numerous advanced apparatuses, such as grinders, milling machines, CNC machines, and lathes, among others, is typical in precision machining jobs. The ultimate goal of precision machining is ensuring the produced parts are exact replicas.
Precision Machining Jobs
There are various precision machining jobs in the CNC industry, but here are the most common types:
1) CNC Machinist: A CNC machinist operates and maintains CNC machines. They can interpret blueprints, set up and operate machines, understand and apply geometric dimensions and tolerances, and alter or adjust machine settings when necessary.
2) CNC Operator: A CNC operator loads parts into a machine, selects the appropriate tools, enters the required program and oversees the machine to ensure it’s running correctly.
3) CNC Programmer: A CNC programmer creates and reviews programs for the CNC machines. They must have a solid understanding of the machines, tools, and processes used in the production floor. They must also interpret project blueprints, establish the sequence of machine operations, and decide on the best tools to complete the job.
4) Quality Control Inspector: This job entails ensuring that the created parts meet the high standards of precision machining. Quality Control Inspectors measure and assess the produced item using precision measuring tools to ensure it’s within the specified tolerance.
Required Skills
Regardless of the specific job, there are fundamental skills required in precision machining. These include mechanical aptitude, attention to detail, strong mathematical skills, ability to read and comprehend blueprints, use of precision measuring tools, problem-solving capabilities, and knowledge of CNC programming and operating.
Average Salaries
The Bureau of Labor Statistics reports an average salary of $40,070/year as of May 2020 for machinists, including those in precision occupations. However, with increased experience and specialized skills, one can make upwards of $50,000 per year or more.
Final Thoughts
With the growing sophistication of technology and goods, there is an increased demand for precision machining jobs in the CNC industry. However, these are not routine jobs. They require specialized training, high precision, meticulous attention to detail, and a deep understanding of manufacturing processes. In return, they offer rewarding career paths for those with a keen interest in this realm of manufacturing.
