CNC Machinist - Lathe
A Snapshot of Your Day
Join Our Team as a Horizontal Lathe Computerized Numerical Control (CNC) Machinist where your skills will beutilized to manufacture large generator shafts for the power generationindustry. These shafts can be up to 46 feet long and weigh as much as 275 tons.
Emphasis is placed on the ability to adhere to all safety requirements, followengineering drawings (blueprints) and interpret and execute manufacturing processes per specific work instructions and validate your work utilizingelectronic quality control documentation.
CNC Lathe Machinistresponsibilities will involve performing precise setups, preparing steady restswith the proper bearings (shoes), working with licensed crane operators toprecisely load the shaft, attaching drivers and then aligning the workpiece inthe lathe. Work instructions are provided electronically with easy-to-usefeatures to record notes, ask questions and communicate with your peers as it takesnumerous shifts to fully machine a generator rotor shaft.
Communication is key.
You will collaborate with your technical support team on how processes can befurther improved which include both machining techniques and ability to recordcritical to quality (CTQ) dimensional features. There is an expectation toshare knowledge, resolve issues, and add your own learnings and experiences tothe knowledge base of the lathe team. We are an organization with a focus onconstant improvement via collaboration and ingenuity.
We value the intellectual property that you bring, and we will significantly add to your existing set of lathemachining skills and capabilities. You will need to be able to work independently and collaborate effectively to ensure successful product delivery to our customers worldwide.
