Definitions

  • the invention relates to a method for the machining of workpiece surfaces, wherein with the aid of a finishing tape finishing material is removed, via which the removed material is substantially removed.
  • US 5,371,973 discloses an unspecified lubricant supplied to abrasive belts via nozzles.
  • DE 196 07 778 A1 discloses that for cutting operations with geometrically defined cutting edge cooling and detergent can be used.
  • the invention has the object to improve a generic method such that the problems mentioned can be avoided.
  • This object is achieved in that takes place using the principle of minimum quantity lubrication of the material removal process using minimum amounts of a cooling and / or lubricating-acting production aid.
  • the process according to the invention has the significant advantage that only very small quantities of the production aid must be disposed of. As a result, the environmental impact of the finishing process is significantly improved. In addition, cost advantages can be achieved, since with less effort legal requirements met and only small quantities of the production process aid must be disposed of costly. In addition, the health burden of the staff can be reduced because it is exposed to only minimal amounts of production auxiliaries and no longer, as in the prior art, larger amounts of coolant. Another advantage is that the cleaning effort of the machine, with which the finishing process is performed, can be significantly reduced.
  • Minimal quantity lubrication has hitherto only been used in machining processes using cutting tools with geometrically determined cutting edges. Since heat removal is critical even in these processes in which comparatively few cutting edges are in engagement with the material to be processed, the principle of minimum quantity lubrication has also been used for grinding and / or finishing operations in which the heat removal is due to the large number of geometrically indefinite cutting edges even more critical is to apply, previously rejected. The experts assumed that a minimum quantity lubrication would not be possible during a grinding and / or finishing process. However, it has surprisingly been found that although it comes to the above-mentioned problems in grinding processes, in finishing processes it is possible to use the minimum quantity lubrication and thereby achieve high to highest surface finishes.
  • the finishing belt can be used once per point of action and then be transported away by suitable transport devices, so that a new section of the finishing belt comes into contact with the workpiece.
  • the removed material is essentially transported away via the finishing belt.
  • the removed material and the production aid or components of the production aid form a moist abrasive mass. This takes in comparison to the known from the prior art coolant only a small volume and can be handled accordingly easier.
  • an air-oil mixture can be used, which can be provided by appropriate minimum quantity lubrication systems.
  • compressed air can be supplied to an injector, in which oil droplets are atomized, so that a fine air-oil mixture is formed. This can then be supplied to the site of action.
  • the air-oil mixture further adjuvants can be added, for example, to further improve the lubricating effect.
  • the workpiece can be driven in rotation, preferably at 50 to 150 revolutions per minute.
  • the workpiece may also be driven slower or faster rotating, but the values mentioned have proven to be suitable in experiments proved to achieve a good surface quality with acceptable processing times.
  • the workpiece and / or the finishing belt can also be driven in an oscillating manner additionally or optionally relative to one another.
  • the surface quality can be further improved.
  • oscillation frequencies of 50 to 400, in particular from 100 to 200 per minute have been found to be advantageous.
  • the oscillation frequency may be lower or higher.
  • the production aid and / or other auxiliaries can be applied to the finishing belt before the material removal process is carried out. This has the advantage that a defined entry of the production aid and / or other auxiliaries can take place.
  • the production aid and / or further auxiliaries can additionally or optionally also be applied to the workpiece surfaces before the material removal process is carried out. This also makes it possible to achieve a good dosage of the auxiliaries used.
  • the order on the finishing tape and / or the workpiece surfaces can be done with the help of a soaked pulley and / or by a bath and / or by spraying.
  • the production aid and / or further auxiliaries may additionally or optionally also be introduced directly into a contact region formed between finishing belt and workpiece surface.
  • the material removal process can be carried out at least twice, for example in order to achieve a high material removal with a first removal process and with a second removal process a particularly high surface quality.
  • different production aids and / or other auxiliaries can be used for successive material removal operations, for example oil for a first material removal process and emulsion for a second material removal process.
