Abstract

The multi-spindle vertical broaching machine has an hydraulic stroking cylinder under the working table and is used for broaching heat exchangers. The broaching tools are supported above the working table and are lowered selectively to suit the hole configuration. Each tool has its upper end attached to the rod of an hydraulic cylinder and can be lowered independently of the others, its pull end being gripped in a standard head on the stroking cylinder. The work table is mounted on tracks and moves in accordance with a programme predetermined in conjunction with the movements of the broaching tools.
