Technical information

Diamond grinding point oval shape 16x25x8 mm D852 for grinding grey and nodular cast iron

Dia. external: 16 mm
Dia. shank: 8 mm
Grit size: D 852
Length, shank: 40
Width: 25 mm
Packaging unit: 1 piece

Description

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

Advantages

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
