Patent number: 10376971Abstract: A pipe milling machine for separating and/or cutting a pipe to length includes a drive unit configured to generate a feed force to the pipe and a holding device configured to hold the pipe. The holding device is mountable around the pipe, the drive unit engages in or touches down on the holding device, the feed force is transferred to the holding device in a location, which contacts the pipe or which is adjacent to a location which contacts the pipe, and/or the drive unit is guided by the holding device.Type: GrantFiled: May 3, 2017Date of Patent: August 13, 2019Assignee: C. & E. Fein GmbHInventors: Armin Eisenhardt, Boris Richt, Jonas Buck
