Toolhead
A toolhead is a component of a machine or tool that is held and acts directly on the workpiece. Toolheads can allow for a modular assembly or easier change of tools for different tasks or maintenance. Toolheads can be subtractive and/or additive, that is add or remove material during operation. The position of a toolhead in a machine is important for repeatability, and in numerically controlled machines its position is often calibrated in a process called homing during a machine's startup procedure.
Some examples of toolheads are:
- Printhead, component of a printer responsible for transferring ink, toner or heat onto the print medium, such as paper, fabric, or plastic
- Robot end effector, also called toolhead, the device at the end of a robotic arm that interacts with the environment
- Screwdriver bits, sockets and drill bits, interchangeable toolheads enabling use of screwdrivers, socket wrenches and other tools with "bit-drivers" on fasteners with different screw heads by using the corresponding bit
- Toolhead or printhead, component of a 3D printer responsible for transferring material onto the onto the workpiece, for example via filament, powder or resin. One of the main movable parts of a 3D printer which contans the hotend and, if applicable, also a direct-drive extruder.
- Toolhead, assembly sometimes used on handloading that holds a die, enabling change between different dies without losing their adjustment, thereby increasing output
- Toolhead, part of a milling machine, lathe or other machine tool that holds the cutting tool itself, such as a drill bit or other tools for shaping materials
