Abstract:
PCT No. PCT/EP95/00494 Sec. 371 Date Oct. 21, 1996 Sec. 102(e) Date Oct. 21, 1996 PCT Filed Feb. 10, 1995 PCT Pub. No. WO95/23664 PCT Pub. Date Sep. 8, 1995The invention relates to a method of producing concave, self-contained bearing surfaces, which are at least part of spherical indentations which extend beyond the sphere equator, by means of machining involving the removal of material of pre-formed indentations in workpieces by means of a tool having a tool cutting edge orbiting around a tool axis of rotation with an orbit diameter which is equal to the length of a chord extending up to a deepest point of the bearing surface, whereby the cutting movement is made up of the orbital movement of the tool cutting edge and a rotational relative movement between workpiece and tool around a vertical axis through the sphere center, and the feed movement is a movement of the tool relative to the workpiece along the tool axis of rotation which is obliquely set at the same angle of inclination relative to the vertical axis as is the chord set to the sphere equator. For reducing manufacturing times and increasing the dimensional exactitude of the bearing surface it is proposed in accordance with the invention that the chord (S) originates from the sphere equator (A), and the regions of the indentation (7) to the two sides of the sphere equator (A) are machined with two separate feed movements. The invention further relates to a bearing surface as product of this method.
