  • Patent number: 9180536
    Abstract: A device has a work piece spindle for accommodating a bevel gear work piece, a tool spindle for accommodating a grinding wheel having an abrasive surface, and a plurality of drives for machining the bevel gear work piece. During machining of the bevel gear work piece, the grinding wheel rotates about the rotational axis of the tool spindle and engages the bevel gear work piece to remove material.

  • Patent number: 9174361
    Abstract: A method for simultaneously slicing a multiplicity of wafers from a substantially circular-cylindrical workpiece that is connected to a sawing strip includes executing a relative movement between the workpiece and a wire gang of a wire saw with the aid of a forward feed device with a defined forward feed rate so as to slice the wafers. The forward feed rate is varied through the course of the method and includes being set to a value v1 at a cutting depth of 50% of the workpiece diameter. Subsequently, the forward feed rate is to a value v2>1.15×v1 as the forward feed rate passes through a local maximum. The forward feed rate is set to a value v3<v1 when the wire gang first comes into contact with the sawing strip. The forward feed rate is increased to a value v5>v3.

  • Patent number: 9138861
    Abstract: The present disclosure relates to a two-phase cleaning element that enhances polishing pad cleaning so as to prevent wafer scratches and contamination in chemical mechanical polishing (CMP) processes. In some embodiments, the two-phase pad cleaning element comprises a first cleaning element and a second cleaning element configured to successively operate upon a section of a CMP polishing pad. The first cleaning element comprises a megasonic cleaning jet configured to utilize cavitation energy to dislodge particles embedded in the CMP polishing pad without damaging the surface of the polishing pad. The second cleaning element is configured to apply a high pressure mist, comprising two fluids, to remove by-products from the CMP polishing pad. By using megasonic cleaning to dislodge embedded particles a two-fluid mist to flush away by-products (e.g., including the dislodged embedded particles), the two-phase pad cleaning element enhances polishing pad cleaning.
