INFORMATION

One of our unparalleled strengths is the uncompromising sintered quality of our grinding pins. Here are a few basic

information that might be useful:

Diameter

The diameter of the internal grinding tool should not exceed 2/3 to 3/4 of the bore size, since the pressure due to the contact zone would otherwise get too high, which could lead to geometrical deviations.

Shank

For our grinding pins we generally use shanks made out of specially hard steel. Such a shank is sufficient for most grinding tasks, which is why we offer it by default. We do, however, also manufacture grinding pins with quills made of heavy metal or carbide, if particular high rigidity is required.

The rigidity can be optimized more simply with a shank as thick as possible, a relief as short and thick as possible as well as by reducing the projection length to a minimum. The rigidity of the shank increases by a factor of about 16 by doubling the thickness of the shank, by a factor of approx. 8 by halving the projection length, but only by a factor of about 2.6 by choosing carbide over steel.

Grinding stroke

To avoid geometrical deviations, the grinding stroke should be adjusted so that the grinding pin does not over travel the workpiece with more than 1/3 of its own width.
