The three kinds of machine tool probes in the market include an infrared probe, radio probe, and wired probe, among which infrared and radio probe is the most widely used. Their characteristics will be introduced in detail in this paper.
Difference Between Infrared and Radio Touch Probes:
The infrared probe housing and the receiver are transmitted through the infrared wave, and the radio probe signal is transmitted through the radio wave.
Advantages and Disadvantages of Infrared Probe:
Advantage:
1. The attenuation coefficient is small during signal transmission, which can ensure effective signal transmission
2. Strong anti-interference and no frequency interference
3. Strong interchangeability and the transmitter and receiver frequency need to be different. When there are many machine tools in a workshop, there is no particular channel for installing an infrared probe. It can be switched on any machine tool for convenient management.
Disadvantages:
1. The transmission distance is limited, and the transmission distance is within 5m
2. The signal is easily blocked and has poor penetration ability. For example, the probe should extend into the cavity for detection when machining deep cavity parts. If the infrared probe is used, the signal will be unstable.
Advantages and Disadvantages of Radio Probe:
Advantage:
1. The signal transmission is not affected by distance and is suitable for large and gantry machining centers. When the measurement distance exceeds 5m, the radio probe must be used
2. Strong signal transmission and penetration ability, suitable for processing and measurement of the deep cavity and large parts
Disadvantages:
1. The signal transmission quality is unstable and vulnerable to interference signals. For example, in large factories, there are too many machine tools, and the channels may interfere with each other, resulting in frequent alarms of the probe.
