Definitions

  • the invention relates to a method for processing Workpiece surfaces, using a finishing agent finishing material is removed.
  • the invention is based on the object to improve a generic method such that the mentioned problems can be avoided.
  • This object is achieved in that the Material removal process using minimum quantities of a Cooling and / or lubricating and / or rinsing acting Production aid takes place.
  • the process according to the invention has the significant advantage that only very small quantities of the production aid must be disposed of. This will be the Environmental compatibility of the finishing process significantly improved. In addition, cost advantages can be achieved because with less effort meets legal requirements and only small ones Quantities of production facilities are disposed of costly have to. In addition, the health burden of the Staff are reduced because this is minimal Quantities of the production aid is exposed and not more, as in the prior art, larger quantities of Coolant. Another advantage is that the Cleaning of the machine with which the finishing process can be significantly reduced.
  • the minimum quantity lubrication has only been up to now Cutting operations using cutting tools with geometrically determined cutting used. Since already at these operations, where comparatively little cutting in the Engage with the material to be processed, the Heat removal is critical, became the principle of Minimal quantity lubrication also with grinding and / or Finish operations in which the heat removal due to the Variety of geometrically indefinite cutting still more critical to apply, previously rejected.
  • the material can be removed by a finishing stone, but also by a finishing tape.
  • a finishing tape this can be used once per active site and then be removed by suitable transport devices, leaving a new section of finishing belt with the workpiece comes into contact.
  • the abraded material may be substantially above the Final agent be removed. This form the abraded material and the production aid or Components of the production process aid a moist Abrasion mass. This takes in comparison to from the state oftechnik known cooling lubricant only a small volume and can be handled accordingly easier.
  • an air-oil mixture can be used be done by suitable minimum quantity lubrication systems can be provided.
  • compressed air be fed to an injector in which atomized oil droplets so that a fine air-oil mixture is produced. This can then be supplied to the site of action.
  • the air-oil mixture can be mixed with other auxiliaries are, for example, the lubricity on improve.
  • the workpiece can be driven in rotation, preferably with 50 to 150 revolutions per minute.
  • the workpiece can also be driven slower or faster rotating, the However, these values have proven to be suitable in experiments proved to be a good surface quality at acceptable Achieve processing times.
  • the workpiece and / or the finishing agent can also be added or optionally driven oscillating relative to each other become. As a result, the surface quality can be further improved become.
  • oscillation frequencies of 50 to 400, in particular from 100 to 200 per minute as advantageously proved.
  • the oscillation frequency can but also lower or higher.
  • the production aid and / or other auxiliaries can be applied to the finishing agent before the Material removal process is performed. This has the advantage that a defined entry of the production aid and / or other auxiliaries can be carried out.
  • the production aid and / or other auxiliaries can additionally or optionally also on the workpiece surfaces be applied before the material removal process is carried out. This also allows a good dosage of used adjuvants are achieved.
  • the order on the finishing agent and / or the Workpiece surfaces can be soaked with the help of a Deflection pulley and / or by a bath and / or by spraying respectively.
  • the production assistant and / or others Adjuvants may additionally or optionally but also directly in a between finishing agent and workpiece surface be formed formed contact area.
  • the material removal process can be at least twice be performed, for example, with a first Abtragvorgang a high material removal and with a second Abtragvorgang to achieve a particularly high surface quality. This can be done for successive material removal operations various production aids and / or more Excipients are used, for example. Oil for a first Material removal process and emulsion for a second Materialabtragvorgang.
