Precision Machining

Precision Machinists use many machine tools, such as lathes, milling machines, grinders, and drill presses, to produce precision metal / non-metal parts. These parts must be made to exacting standards, and the machinist uses precision measuring instruments to ensure accuracy and that the parts meet quality guidelines. A machinist reads and interprets specifications and blueprints, calculates dimensions and tolerances, lays out their work and marks pieces for machining. Precision machinists often produce small batches or one-of-a-kind items. They use their knowledge of the working properties of metals and their skill with machine tools to plan and carry out the operations needed.

The job of the precision machinist combines mental ability with manual skills – to develop a project from a blueprint requires careful thought and an understanding of mathematics and design of work holding devices in conjunction with the engineering department, as well as good mechanical ability. You will be making one of kind items for research and development, tooling, fixtures and small run batches. You may be required to fit and assemble the machined metal parts and subassemblies, and verify their dimensions, strength and hardness.

Main duties

Machinists perform some or all of the following duties:

  • Read and interpret engineering drawings, blueprints, charts and tables or study sample parts to determine machining operation to be performed, and plan best sequence of operations
  • Compute dimensions and tolerances and measure and lay out work pieces
  • Set up, operate and maintain a variety of machine tools including computer numerically controlled (CNC) tools to perform precision, non-repetitive machining operations such as sawing, turning, milling, boring, planing, drilling, precision grinding and other operations
  • Fit and assemble machined metal parts and subassemblies using hand and power tools
  • Verify dimensions of products for accuracy and conformance to specifications using precision measuring instruments
  • May set up and program machine tools for use by machining tool operators.
