Abstract
A device for keyway broaching is provided with a housing, a drive shaft, a broaching carriage received and supported in the housing, a tool support connected to the broaching carriage, and a crank drive that couples the drive shaft and the broaching carriage with each other. The broaching carriage, when driven by the drive shaft, performs an oscillating movement comprising a cutting movement and a return stroke. A sleeve is arranged between the housing and the broaching carriage. A first seal is provided between the housing and the sleeve and/or between the sleeve and the broaching carriage. The tool support is connected to the broaching carriage with a rocking lever interposed between the tool support and the broaching carriage. The drive shaft has a control section that controls a relative movement between the rocking lever and the broaching carriage.
