Renishaw MH20i

MH20i is a manually adjustable probe head that combines the TP20 kinematic stylus module mount with two axis indexing.

The A-axis rotates through ±180° in the X-Y plane. The B-axis rotates through 90° in the Z plane. A lever locks the head in one of up to 168 repeatable positions, set at 15° increments.

The head is capable of carrying the full range of TP20 modules, which can be changed without re-qualification, providing qualification has taken place in each position with each stylus/module combination.
