  • Publication number: 20100186560
    Abstract: During the machining of workpieces, in particular dynamic loads act on the cutting tools in addition to the static loads. This leads to chipping at the cutting edges of the cutting elements and thus to the destruction of the cutting element with the possible consequence that the workpieces is damaged and thus becomes useless.

  • Patent number: 7762165
    Abstract: There is provided a method of manufacturing an optical element having a circular portion and at least one annular zone formed thereon, the circular portion having a circular profile and centered about an optical axis as viewed from a direction of an optical axis, the annular zone having an annular zonal face and a boundary wall face formed concentrically around a periphery of the circular portion, and the boundary wall face linking between the circular portion and the annular zonal face. The method is performed by rotating a workpiece about a rotation axis corresponding to the optical axis, and allowing a sharply pointed front end of a tip to prick the workpiece to a portion corresponding to an angled portion defined by the annular zonal face and the boundary wall face so that the annular zonal face is formed by side edges of a rake face of the tip.

  • Patent number: 7712401
    Abstract: A cutting head assembly holds a pair of tool bits for an on-vehicle brake disk lathe having a platform. The cutting head assembly has a platform key fixed to the platform and extending parallel to a brake disk axis of rotation. The cutting head assembly also has a plate having a plate keyway that slidably engages the platform key. Tool bit arms are adjustably mounted to the plate and support the tool bits. A locking structure connected to the plate locks the platform key with respect to the plate keyway, and the interaction of the locking structure with the plate and the platform key creates a compressive load between the plate and the platform as the platform key is locked with respect to the plate keyway.
