Introduction

Introduction
The MH8 is a manually operated, indexable probe head that
articulates to provide orientation of the probing axes. The head can
carry probes fitted with a Renishaw M8 connector. The TP20 and TP6
touch trigger probes are recommended. The MH8 is available with a
range of shanks to suit the mounting arrangement specified for the
ram of the CMM, by the manufacturer.

Product description

The MH8 has 2 swivel axes. The probe connector is carried on the A
axis swivel which can rotate the probe through 90° in the Z plane. The
B axis can rotate the probe through ±180° in the X-Y plane.
A lever actuated mechanism locks both axes in the desired position
for gauging the workpiece. The axes are unlocked to allow free
rotation to another position. The locked positions are set at angular
increments of 15° in each axis, providing a total of 168 positions.
When the 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, in the positions required for
gauging the workpiece, the probe may be reorientated to any of the
qualified positions without the need for requalification.
A red LED is provided on the front of the head to indicate probe
status. The LED may be driven by the CMM controller or by a
Renishaw probe interface. It is normal convention for the LED to be
ON to indicate a seated (armed) probe and to be OFF to indicate a
triggered probe.
Electrical connection is via a 5 pin Din connector.
