FRICTION AND VERTICAL CUTTING TOOL

摘要

The invention relates to a friction and vertical cutting tool comprising a base body (2) to which a cutting knife (20) is interchangeably clamp-fixed by means of a clamping bolt, in such a way that it is removable. Said cutting knife can also be adjusted in its radial position by means of an adjusting member (40) via an adjusting element (30). According to the invention, said adjusting element (30) comprises a cutting knife support extending in a recess of said base body and said adjusting member (40) is a differential screw which is positioned in threaded engagement with said adjusting element. Alternatively, said adjusting element (30) can be a cutting knife support extending in a recess of the base body and said adjusting member (40) can be a ball or clamping member which has a positive fit with a complementary recess of said adjusting element in such a way that a movement of said adjusting member causes said cutting knife (20) to move in the same direction. One advantage of the invention is that at least one coolant hole is provided leading to the cutting area with at least one branch connection hole (22) in the front area of said coolant hole leading outwards. This construction allows coolant and lubricant to be delivered to the cutting area.
