切削ウォームのねじ山間隙にドレッシング工具をセンタリングするための装置ならびに方法

Document Type and Number:

Japanese Patent JP5255680

Kind Code:

B2

Abstract:

In a first step for the purpose of precentering, the dressing too; (27), without axial movement, is brought into contact with the circumference of the rotating grinding worm (11), and those rotary-angle positions of the grinding worm (11) at which the overrunning of the thread gap (36) starts of ends are determined by means of an acoustic-sensor signal and the shaft-angle encoder (18) of the grinding spindle (16). In a second step for the purpose of precision centering, the dressing tool (27) fed into the thread gap (36) is brought into contact with the left-hand and right-hand tooth flanks (38, 39) by axial displacement. In this case, the axial infeed is stopped by means of the acoustic-sensor signal, and the exact grinding-worm thread center is calculated from the contact positions of the dressing tool (27) achieved.
