Electroplated diamond and CBN grinding points are used for both wet and dry grinding.

Diamond grinding points with grit size D 852 are exceptionally well-suited to machining grey cast iron and nodular cast iron (GG and GGG or GJL and GJS).

N = non-stepped shank

  • Excellent tool life.
  • Fast, aggressive grinding with maximum stock removal rate.
  • Easy and quick elimination of metal contamination thanks to diamond as a super-hard abrasive.
  • Lower dust load due to the dimensional stability of the grinding tool (no tool wear).
Recommendations for use
  • Application is possible for both dry and wet grinding. If possible, wet grinding is to be preferred in order to reduce tool wear and the risk of thermal damage.
  • Generally, the following applies: For optimum economic efficiency, select a grit size that is as coarse as possible and as fine as necessary. Influencing factors include the hardness of the material and the surface quality required.
  • Loaded tools can be cleaned using ultrasound. In the event of strong contamination on the coating, please clean using the sharpening block DSB 2005025 (EAN 4007220168332).
  • Select as large a tool diameter as possible, as this increases the amount of grit that engages the workpiece. For internal grinding, the maximum tool diameter is 3/4 of the diameter to be ground.
  • The longitudinal feed rate for internal grinding must not exceed 2/3 of the total width per workpiece rotation. The infeed depends on the material to be machined, the cutting speed, the stability of the tool, its holder and the tool drive.
  • Because of the monolayer coating, the drive spindle and tool mounting must have a high concentricity. The finer the grit size used, the more accurate the concentricity needs to be.
  • The tool drive must have sufficient drive output on the grinding spindle to ensure the required rotational speed, even under load.
  • Dry grinding: 30–50 m/s
