Patent number: 8215295Abstract: A rotatable cutting tool unit of a tool assembly for a cutting machine that is used in conjunction with an associated method of cutting provides several novel aspects. The tool arrangement, which includes two tool units, includes first and second disk-shaped tools rotatable about an axis. The tools define maximum tool arrangement boundaries along the axis. A driving arrangement, at an axial location between the first and second tools, supports the first and second tools for rotation and transfers driving force. A radially outer periphery of the driving arrangement is at a radius less than a radius of a peripheral cutting edge portion of the first tool and less than a radius of a peripheral cutting edge portion of the second tool.Type: GrantFiled: July 14, 2009Date of Patent: July 10, 2012Assignee: Husqvarna ABInventors: Ove Donnerdal, Håkan Pinzani, Mari Albinsson

Patent number: 8037948Abstract: A drilling machine includes a motor housing, a gear box housing, a shaft driven by the motor and extending into the gear box housing, a drilling shaft extending through the gear box housing and having an outgoing channel arranged in the drilling shaft for supply/removal of a drill flow medium to/from a tool part that is connectable to the drilling shaft, a drill flow medium room, between the motor housing and gear box housing, that can be supplied with drill flow medium when the drilling machine is in operation, and an incoming drill flow medium conduit for the supply/removal of the drill flow medium to/from the drill flow medium room. The motor housing includes a detachable end cover which forms the rear unit of the drilling machine. The gear box housing includes a detachable end cover that forms the front unit of the drilling machine.Type: GrantFiled: August 31, 2007Date of Patent: October 18, 2011Assignee: Husqvarna AktiebolagInventors: Mari Albinsson, Klas Nordgren, Ulf Petersson
