A combination machine is a woodworking machine that incorporates the functions of two or more machines into a single unit. Some popular combinations:
Tablesaw with a side-mounted jointer.
Jointer-thicknesser (consisting of a jointer and planer).
[Jointer-thicknessers may also use the same cutter head for both functions.]
Some combination machines run all their functions from a single motor, while others may use two or more motors, depending on manufacturing needs. Combination machines rely on well orchestrated design to allow users to switch from one function to another easily.
