Abstract

849,770. Grinding. HACK, K. March 13, 1959 [March 14, 1958], No. 8709/59. Class 60. A spring end grinding machine of the type comprising two parallel rotating grinding discs with means, e.g. a rotary carrier, for carrying the spring or springs between them so that the spring ends engage the grinding faces of the discs, in which at least one of the grinding discs is axially adjustable, is characterised in that each grinding disc is driven by an axially hollow shaft, one of which shafts penetrates into the other telescopically for relative axial movement and in that cooling medium is supplied to the discs through the axial bores in the respective shafts. The lower grinding disc 3<SP>1</SP> is mounted on a hollow shaft 1<SP>1</SP> driven by a motor 21 and within which is a hollow shaft 2<SP>1</SP> on which the upper grinding disc 4<SP>1</SP> is mounted. The shaft 1<SP>1</SP> has six keyways 5 two of which receive keys 26, 26<SP>1</SP> rotationally connecting thereto the axially adjustable shaft 2<SP>1</SP>. A bush 16<SP>1</SP> has channels 9<SP>1</SP> communicating with the keyways. Coolant supplied by a pump 14<SP>1</SP> through regulating valve 151 to the interior of the shaft 1<SP>1</SP> passes (a) through the keyways and channels 9<SP>1</SP> to the lower disc 3<SP>1</SP> and (b) through the interior of the shaft 2<SP>1</SP> and through passages 29, 30 to the upper disc 41, a deflecting plate 18<SP>1</SP> being provided.
