20110088515 | SHARPENING DEVICE FOR MANUALLY SHARPENING THE CUTTING TEETH OF SAW CHAINS FOR CHAIN SAWS - A sharpening device for manually sharpening the cutting teeth of saw chains for chain saws has a frame, which has two head parts (spaced apart from one another and two pairs of guide rods which are, in each case, arranged parallel to one another and to a longitudinal axis and rigidly connect the head parts to one another. Parallel to the longitudinal axis, round files and two file faces are held without play, but exchangeably in the head parts. The pairs of guide rods and the respective associated round files and the respective file faces are arranged rotationally symmetrically with respect to the longitudinal axis. | 04-21-2011 |
20110065369 | ROUGHING-GRINDING DISC - A roughing-grinding disc consists of a plurality of part discs, which are flat in design, are located closely against one another, unconnected and uncovered, in an outer working region, are rigidly connected to one another in an inner connecting region located within the working region and are provided with a hub passing through the grinding disc in a centre opening. | 03-17-2011 |
20110045750 | ROUGH GRINDING TOOL - A rough grinding tool has a support plate with a centre opening arranged concentrically with respect to a centre longitudinal axis for receiving a drive shaft of a drive machine. Supported on the support plate is a fiber grinding disc, which is formed from a fiber disc being used as a carrier and a resin-bound grinding means covering. The fiber grinding disc is glued to the support plate. | 02-24-2011 |
20090305619 | FAN-TYPE GRINDING WHEEL - A fan-type grinding wheel comprises a rigid support plate and is provided with grinding elements. These grinding elements comprise a main portion forming a first working face and a bending portion forming a peripheral working face. Furthermore, they comprise an outer portion forming a second working face. | 12-10-2009 |
20090205844 | HOOF PLANE - A hoof plane comprises cutting teeth with cutting edges which extend perpendicular to the longitudinal axis and therefore to the working direction. The cutting teeth and the chip breaker grooves are formed by machining and extend at an angle of 45° relative to the longitudinal axis. The hoof plane consists of a high-quality tool steel and has a hardness of at least 64 HRC. | 08-20-2009 |
