the boring process can be executed on various machine tools, including 1 general-purpose or universal machines, such as lathes /turning centers or milling machines /machining centers , and 2 machines designed to specialize in boring as a primary function, such as jig borers and boring machines or boring mills, which include vertical boring mills workpiece rotates around a vertical axis .
a jigsaw power tool is a jigsaw made up of an electric motor and a reciprocating saw blade.. jigsaws with sole plates that have a beveling function can cut angles typically up to 45 degrees relative to the normal vertical stroke to make miter joints.. in the past, what are now usually called scroll saws were often referred to as jigsaws.
a jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. the jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate far more so than a manual milling machine or lathe . it is almost exclusively used by tool and .
honing machines are much more compliant than grinders. the purpose of grinding is to achieve a tight size tolerance. to do this, the grinding wheel must be moved to an exact position relative to the workpiece. therefore, a grinding machine must be very stiff and its axes must move with very high precision.
centerless grinding uses purpose-built centerless grinding machines. such a machine will always include the grinding wheel, regulating wheel, and some means of supporting a workpiece. modern machines may involve computer numerical control to allow automation and improve precision.
a garbage disposal unit also known as a waste disposal unit, garbage disposer, garburator etc. is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap.the disposal unit shreds food waste into pieces small enough—generally less than 2 mm 0.079 in —to pass through plumbing.

a pneumatic die grinder with a right-angle head. a cordless battery-powered rotary tool used for light tasks. die grinders and rotary tools are handheld power tools used for grinding, sanding, honing, polishing, or machining material typically metal, but also plastic or wood . all such tools are conceptually similar, with no bright dividing .
the universal motor is modified in several ways to allow for proper ac supply operation. there is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in dc motors. a universal motor's armature typically has far more coils and plates than a dc motor, and hence fewer windings per .
