Abstract: An apparatus includes a blade grinding machine, a measuring system and a control for providing a bar blade suitable for cutting work pieces. The blade grinding machine includes a clamping mechanism for mounting the bar blade and a grinding wheel for grinding the mounted bar blade. The measuring system also includes a clamping mechanism for mounting bar blade and at least one probe for three-dimensional sampling of the bar blade mounted on the measuring system. The control enables a data exchange between the blade grinding machine and the measuring system in order to grind and sample the bar blade in an alternating fashion. The apparatus is a closed system in which data exchange is automated.

Abstract: A grinding wheel (28) that rotates around an axis and that has a working area consisting of an annular surface with a circular arc profile in axial cross section is used to first generate a surface on a cutting blade (22) by grinding with the annular surface during a first orientation in space between the grinding wheel (28) and the cutting blade (22) by means of at least one first relative translational movement between the same, and subsequently at least one part of the generated surface is reground with the annular surface during a second orientation in space between the grinding wheel (28) and the cutting blade (22) by means of at least one second relative translational movement between the same. The grinding wheel (28) is a diamond cup-type grinding wheel. One part (34′) of the working area (34) is located in a face area and another part (34″) is located in a cylinder area of the grinding wheel (28).

Abstract: A grinding wheel and a method for grinding bar blade for the production of spiral gear teeth are described. For economical grinding of such bar blades the grinding wheel has a conical grinding surface (Pp) widening from a small diameter (d1) to a large diameter (d2), a cylindrical grinding surface (Ps) adjoining the conical grinding surface (Pp), and a toroidal grinding surface (G) adjoining the cylindrical grinding surface (Ps). The grinding wheel embodied in this manner enables profile grinding (rough grinding) and subsequent generating grinding (finish grinding) of the surfaces of the bar blade without the necessity of remounting the blade. For practical purposes the grinding wheel rotates about a stationary axis (S), and the bar blade to be ground is guided along the grinding wheel at appropriately set angles.
