Introduction

Renishaw's MIH is a compact manual indexable probe head which offers the flexibility and time saving normally associated with direct computer controlled (DCC) machines and motorised probe heads.

The MIH is adjustable in two axes, both of which can be unlocked by a single thumbwheel operation.  A probe / stylus combination can be orientated to 720 different positions and, once the head is locked, each position will be repeatable to 1 μm* (0.00004 in) (2σ).  Hence the user can return to any chosen position without having to requalify the probe / stylus tip.

The current position is shown on the integral liquid crystal display (LCD) and is constantly updated during moves.

The programmable memory facility allows pre-datumed positions to be stored in a memory within the head.  Direction arrows shown on the LCD take the user back to any one of 20 memorised positions which can be arranged in any order to suit a particular inspection sequence.  The sequence can be edited as required.

Probes are attached to the MIH by means of the Renishaw autojoint, allowing the user to easily exchange probes whilst maintaining repeatability to 0.5 μm* (0.00002 in) (2σ).  The autojoint is recessed into the head, thus maximising the valuable working volume of the machine.
