Abstract

The present invention concerns a procedure and an arrangement for the abrasive precision machining of a blank (1) made of a material with a high degree of hardness and/or toughness by means of a rotating high speed abrasive tool (2) that has a rotation speed of more than 30,000 revolutions per minute (rpm), where the blank is arranged in a liquid (3) and the machining is carried out under the surface of the liquid. The procedure includes a negative prssure being created in the area (4) of the rotating tool's drive axle above the liquid surface. The arrangement includes a driving device that rotates an abrasive tool (2) where the driving device is able to transfer a number of rotations that exceeds 30,000 rpm, a device for holding the blank (1) that is to be machined, as well as a device for adjusting the relative positions of the blank and the tool to one another for carrying out the machining, during which a liquid (3) is arranged to surround the blank (1) during machining so that the machining takes place under the surface of the liquid, whereby a driving device includes a spindle (7) arranged in a spindle housing (8), a forced air stream (9) is arranged in the area of the end of the spindle that supports the tool (10), and a device to direct the flow of air (11) is arranged at a distance above the liquid surface, plus that the flow-directing device is able to change the direction of the forced air stream to flow in a divergent direction (12) relative to the spindle.
