TYPE 5210, 5211, 5220, 5230

5210  -  Mounted points, cylindrical
5211  -  Mounted points, cylindrical-conical
5220  -  Mounted points, conical
5230  -  Mounted points, spherical

These mounted points are intended for precision and rough grinding. Used for work­pieces of cast iron, steel, cast steel. They may be operated on portable pneumatic and electric direct drive grinders.

Operational speed for minimal length the spindle overhangs the grinding machine clamp

40 m/s

The maximum permissible rotational speed for mounted points is depended on the length the spindle overhangs the grinding machine clamp. The permissible rotational speeds for particular clamping situations are shown  in Table 5 on page 27.

The parameters determining mechanical strength of the spindle are: the length the spindle overhangs the grinding machine clamp, geometry of the spindle and the grinding wheel, their material properties and the maximal rotational speed.
