Definitions

  • the invention relates to a method for grinding a workpiece the features according to the preamble of claim 1 and a device to carry out the method with the features according to the preamble of claim 4.
  • Finishing and finishing are usually two consecutive Operations on two specially designed machine tools.
  • the disadvantage here is that on the one hand the number of different Machine tools to a large extent to implement the production a certain component required capital expenditure increased and that on the other hand, the manufacturing costs for the component in question due to higher ones Lead times with intermediate transport operations as well increase.
  • Another disadvantage is that the re-clamping in the machine tool realizing the finest machining Errors can occur which are relevant to the required manufacturing tolerances to prove disadvantageous.
  • Honing is a cutting manufacturing process with bound grain for improvement or changing the shape, dimensional accuracy and surface quality of the workpiece, taking the tool constantly with the surface of the workpiece is engaged. Honing will generally follow a previous one Finishing, such as Grinding, used for finishing. In particular, the so-called short stroke honing is also called fine honing, finish processing or superfinishing, fine drawing or orbital grinding designated.
  • Machine tools for grinding and machine tools are known for example for superfinishing (see company brochure IMPCO Machine Tools, USA, 1994).

  • the grinding unit and the fine machining unit preferably with respect to the workpiece longitudinal axis are arranged essentially on one side of the workpiece. This is advantageous, for example, if only part of the surface of the workpiece must be finely machined and the length of the machined Workpiece is large enough so that fine machining unit and Grinding unit during simultaneous engagement with the workpiece itself not hinder each other.
  • the grinding unit has a carrier which two grinding spindles each with at least one grinding wheel are pivotable and attached to a common feed axis that the grinding wheels can be brought into engagement with the workpiece one after the other are.
  • a grinding unit is especially useful if Different surface contours of the workpiece using the grinding unit are to be processed true to size and shape.
  • the fine machining unit is preferably a fine grinding unit or a Finishing unit trained. Both the fine grinding unit and the finishing unit are used to improve the surface quality of the workpiece or part of it To achieve the surface of this workpiece, which in the area of manufacturing processes commonly referred to as precision machining.
