The MH20 incorporates the TP20 kinematic mount with 2-axis adjustable swivel. The TP20 module is carried on the A-axis swivel and rotates through ±93° in the Z-plane. The B-axis rotates through ±300° in the X-Y plane. A thumbwheel locks the swivel in any position within the movement envelope of the head. After each adjustment qualification must take place. Module changing is possible without re-qualification.
The MH20i incorporates the TP20 kinematic mount with 2-axis indexing. The TP20 module is carried on the A-axis swivel and rotates through 90° in the Z-plane. The B-axis rotates through ±180° in the X-Y plane.
The axes are unlocked by releasing the locking lever allowing rotation to each position. Positions are set at angular increments of 15° in each axis, providing a total of 168 positions.
When head orientation is locked, the probe is fully kinematically constrained in a highly repeatable spatial position.
This means that after initial qualification of the stylus tip, the probe may be moved to any of the qualified positions without the need for re-qualification during a gauging routine.
MH20 and MH20i
The red LED on the front of the head indicates probe status, and can be controlled by either the CMM or a Renishaw probe interface. Conventionally LED ON indicates probe seated (armed), and LED OFF indicates probe triggered.
Electrical connection is via a 5-pin DIN connector.
