Mida™ High Frequency transmission is a wireless signal Transmission system for workpiece inspection suitable both for Lathes and machining Centres.

The High-frequency (HF) transmission system transmits the signals from the probe to the interface unit through an air gap, then to the CNC of the machine tool.

Machining centre and milling machine applications
In machining centre applications the HF transmitter is integrated into the probe holder and fastened to the shank. The HF receiver is screwed near to the spindle.
The probe holder with the integrated transmitter is available in a wide range of dimensions, together with different holders for the spindle mounted module, according to the application needs.

The distance between transmitter and receiver modules must be lower than 3 mm, with misalignment up to 2 mm (0.078 inches). The receiver module is equipped with an 8 m (26.2 ft) cable for connection to the E32S interface unit.

		Lathes applications
		In lathe applications, the transmitter is a cylindrical module inserted into the turret. The receiver is fixed onto the turret holder. Should it be necessary to frequently replace the probe in the turret with a work tool, as in turning center applications, a Twin Air Gap HF transmission system is available

The H.F. transmission system allows the transmission of the signal through two different air gaps.

The system, in the twin air gap configuration, consists of two modules. The first is composed of a transmitter (1) commonly inserted into the removable probe holder and a receiver (2) located into the turret. This sectioning of the electrical connection allows rapid replacement of the turret probe with a work tool and vice versa.
The second module is composed of the repeater (3) placed into the turret and a second receiver (4) located into the turret holder that is connected to the E32S interface unit. The transmitter and the repeater have respectively two and five screw terminals for connection to the cable


The main difference between HF and the other wireless Mida probing systems is the absence of a battery inside the transmission module. In fact the transmitter power supply is received through the receiver module that is continuously powered by the E32S interface unit.

HF is commonly used when probe option is offered by OEM's. Retrofitting existing machines machines can be time consuming due to the high mechanical integration with the machine tool required.

All the system components are completely watertight ensuring operation in even the harshest working conditions.
