Diamond grinding point cylindrical dia. 25 mm shank dia. 12 mm D126 (medium) for grinding holes and radii

Technical information

Description

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

The cylindrical shape ZY is suitable for grinding bores, radii and contours in stationary or manual applications.

N = non-stepped shank

Grinding points with a diameter of 8 mm or more have a recess on the front surface.

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: 8–18 m/s
Wet grinding: 15–25 m/s
