Definitions
- the tool itself consists of a tool shaft and a non-rotatably limited axial Movable tool head with hard material cutting, the tool shank acoustically long and the tool head acoustically on the flying piston and / or striker is coordinated.
- tool shank In the advantageous case of the same material from the die block, tool shank and The cross sections of the tool head are the same.
- the tool head 4 is in relation to one Shock pulse 7, the pulse length equal to twice the acoustic length of the Tool head 4 is adapted, whereby this shock pulse 7 almost completely from Flying piston 5 over the striker 6 and the tool shank 3 into the tool head 4 is transmitted, which in a later point in time essentially with the full Impulse energy rams into a rock 8 to be machined without it becoming one essential back reflection 9 and thus to a loss of pulse energy during transmission comes into the tool head 4.
- the shock pulse 7 When the shock pulse 7 is transmitted, they are each butting end faces 10 in planar contact with each other, whereby the Shock pulse 7 is transmitted essentially as a rectangular pulse.
- Tool head 4 designed like a sleeve, the hexagonal prismatic coupling area 12 of the tool shank 3 rotatably and limited axially movable in the engages matching counterpart forming tool head 4.
- the at least partially in essentially flat design of the end face 10 between the tool shank 3 and the tool head 4 has a very large circular ring area effective radius of curvature realized.
