👉 A groover is a type of machine that uses the principle of friction to cause mechanical motion. It is commonly used in industries such as metalworking and manufacturing, where it helps in reducing the amount of work required by applying force to a surface or tool. In terms of terminology, grovers are often referred to as "frictionless" machines because they do not apply any external force to the surfaces they are applied on. Instead, the frictional forces generated by the machine's movement cause motion
