Common Tools in Industry

Lathe. a machine tool that rotates a workpiece on an axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object with symmetry about an axis of rotation (eg: turning a cylinder).
Drill Press. a machine that drills holes in materials using a drill bit. The drill bit is held in place by a chuck and rotated by a motor while the material is held stationary by a vise (eg: drilling holes in metal).
Grinding Wheel. an abrasive tool used for grinding, which is composed of an abrasive compound and used for various grinding and abrasive machining operations (eg: sharpening knives).
Milling Machine. a machine tool used to machine solid materials such as metals, plastics, wood, and other materials. It uses a rotating cutting tool to remove material from the workpiece (eg: machining intricate parts).
Tapping Machine. a machine that cuts threads into a pre-drilled hole using a tap. The tap is held in place by a chuck and rotated by a motor while the material is held stationary (eg: threading bolts into pre-drilled holes).
