Grinding spindle

9.6.1

Eliminating radial runout and releasing tension

An impact load, for example if the grinding wheel collides with the workpiece, may
result in radial runout of the grinding spindle bearing.

Check the grinding spindle with the aid of a micro-gauge after it has suffered an
impact load. If the runout of the grinding spindle is greater than 0.003 mm, you
must release the tension.

•

Screw two lock nuts onto the spindle (left-hand thread).

•

Loosen the round nut (1) (left-hand thread) with a suitable pin-type spanner.
Counter by holding a fork spanner against the lock nuts on the spindle.

•

Rotate the spindle several times by hand.

•

Tighten the round nut again. Counter by holding a fork spanner against the lock
nuts on the spindle.

•

Check the concentricity.

Repeat this procedure until the radial runout is less than 0.003 mm.
