Abstract (en)
[origin: EP0825003A2] The milling machine has a rotating milling tool with a number of milling chisels (2) around its circumference. A hammering action is induced in one or all of the chisel points through a pneumatic or hydraulic hammering mechanism. The hammering mechanism may comprise pistons (1) enclosed in cylinders (11) and operated by compressed air. The cylinder ends are alternately connected to the air feed and air exhaust sides.
