CNC/Conventional Machinist

Inside Machinist

Position Summary

The inside machinist operates in three sections: Machining, Valves, and Pumps. Responsibilities and functional knowledge vary based on the designated section. All inside machinists are encouraged, but not required, to gain experience in any section other than their designated section.

Key Responsibilities & Functional Knowledge

This list is representative of the key areas of responsibility and functional knowledge required of a first class mechanic in the Inside Machine shop. A first class mechanic must demonstrate an advanced knowledge of the skills, functional knowledge, and abilities required to perform tasks in these and related areas of responsibility. Advanced knowledge means that the mechanic understands how to perform tasks in these categories (including, but not limited to, the specific tasks identified below) and is able to complete them independently and teach others how to complete the tasks. This also means that the mechanic has the necessary level of knowledge of the equipment, protective gear, and machinery required to complete these tasks. A first class mechanic also is expected to strategize independently and problem-solve as appropriate.
