The numerically controlled machinery is capable of performing a broad range of programmed machining functions such as multi-plane boring, drilling, milling, tapping, facing, planning, and other related operations. Because of the high degree of complex interaction among the various devices and subsystems comprising the machine tools, particular indications or symptoms of defects in one device or subsystem may result from any of a multiplicity of possible malfunctions in other devices or subsystems, or from the cumulative effect of a number of discrepancies in other areas. This position is a skilled senior maintenance mechanic with extensive experience within maintenance of production machinery.



High school diploma or general education degree (GED) along with related trade school education, apprenticeship and/or experience.  The ability to interpret complex multi-view drawings, sketches, wiring diagrams, manufacturers' specifications, and other technical material; must be able to read and comprehend blueprints, diagrams and schematics. Ability to perform precise measurements of air and fluid pressure and flow, and knowledge of the mechanisms used to convert such readings into measurable units. Must be skilled in the use of a variety of complex optical and laser light measuring devices. In depth knowledge and understanding of electricity or electronic principles is preferred. Proficient in trade mathematics and machinist handbook formulas in computing and verifying dimensions in the planning, layout out, and final dimensional checking process.



Previously demonstrated mechanical experience required, (i.e., understanding machinery, electrical, hydraulic equipment, properties of metals, welding, piper/plumbing, taped program readers, closed loop servo assemblies, position detection and velocity measurement devices, and machine control bodes) and expert in understanding of complex and aged mechanical tools and equipment required. Certificates and Licenses:  Trade or Vocational certifications preferred. Other particular trade certifications or in-depth experience may be required, (i.e. certifications, weights & measures technology, etc.).  Fork truck license required. Maintains up-to-date technical knowledge of functional duties. This position requires twelve months' work experience to become proficient in all phases of the job.
