CNC (Numerical Control) Machine Operator (Day Shift)

Rolls-Royce•Aiken, SC

13d•Onsite

About The Position

The CNC Operator runs the machining centers in crankcase manufacturing, machining crankcases to exact specifications with in-process quality assurance. The role offers a clear development path. It starts with line boring as the entry point, which needs no prior CNC experience, and grows into CNC machining on the Burkhardt & Weber (B&W) machines, with responsibility and pay increasing as operators progress. With this attractive opportunity you will get a chance to: Set up and machine crankcases according to specifications, routings, control plans, and drawings, on the line boring machine and, at the advanced level, on the Burkhardt & Weber (B&W) machining centers with Sinumerik One control system Bore and align the bearing alleys of the crankcase, including the camshaft and crankshaft bores, re-boring as required to achieve precise alignment Clamp, reclamp, and unclamp crankcases, monitor the process, and correct as necessary Monitor, change, correct, and adjust tools as required Study machining instructions, routings, control plans, job orders, and blueprints to determine dimensional and finish specifications, sequences of operations, machine setups, and tooling requirements Select the appropriate tools and materials for the preparation of crankcase components Set up, adjust, and operate the basic machine tools and many specialized or advanced variation tools to perform precision machining operations Perform fine-tuning through sample cuts and optimize the CNC program with regard to tool durability, collision prevention, and program sequencing Observe machine operation to detect conditions such as dull cutting tools or excessive vibration and adjust to compensate

Requirements

Entry level, line boring: Completed vocational training as a machine and plant operator or a comparable qualification, or a U.S. equivalent such as a mechanical or machining trade school certificate, an Associate's Degree, or relevant hands-on experience in a machining environment
Direct work as CNC Operator on the B&W machines: Completed vocational training as an industrial mechanic specializing in production technology, or a comparable 3.5-year apprenticeship in a metalworking profession, or 2 years of trade school or an equivalent Associate's Degree, or 3 years of experience in a heavy-duty machining environment; several years of experience operating NC-controlled machining centers; and knowledge of Sinumerik One control system
Strong quality awareness and a high sense of responsibility
Physically resilient, reliable, and committed
Willingness to work shifts and occasional weekends
Ability to work overtime as needed
Applicants must be authorized to work for any employer in the U.S. without sponsorship. We are unable to sponsor or take over sponsorship of an employment Visa at this time

Nice To Haves

Experience operating Burkhardt & Weber (B&W) machining centers
Knowledge of Sinumerik One control system would be particularly advantageous
Several years of experience on a conventional boring mill (e.g., Collet) would be an advantage
Experience machining crankcases or large cast components
Intermediate knowledge of CNC controls, machines, and tools, including their designs, uses, repair, and maintenance
Intermediate knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications
Basic ability to interpret Statistical Process Control (SPC) and operate scanning devices for system communications
Basic knowledge of manufacturing and production processes, raw materials, quality control, costs, and other techniques for maximizing the effective manufacture of goods (Quality Alerts, Second Checks, etc.)
