IMM / IMP 유도 전송 모듈

About IMM

The IMM (inductive module machine) is one half of the inductive transmission system. Mounted on the spindle of the machine tool and wired to the CNC via an interface, the IMM provides power to the probe module and receives trigger and status signals from the probe.

The are several types of IMM with various mounting and cable exit options. These have been designed to suit a range of different machine tool installations.

About IMP

The IMP (inductive module probe) forms the other half of the inductive transmission system. Mounted on an arm connected to the probe, the IMP receives power from the IMM via electromagnetic induction, whilst sending probe status and trigger signals across the small air gap to the IMM.

The particular IMP required will depend on the configuration of the machine tool to which the probe is to be installed. A range of IMP arms are available, defined by the J and K, or L and R dimensions shown on the example diagrams below.

Features and benefits

No batteries required
Inductive transmission systems pass both signals and power across a small air gap. This means that the probe can be powered from the d.c. power supply available on the CNC.

OEM installation only
Inductive transmission systems require installation of the IMM to the spindle nose of the machine tool and routing of a cable back into the machine control cabinet. This level of integration is only suitable for factory fitment by machine tool builders.

For retrofit applications, Renishaw's range of optical and radio transmission probes is ideal.
