Blum TC64-20 probe for tool setting and tool breakage detection debuts at MACH 2014

The unit is a wireless system that features Blum's BRC radio technology and is suitable for tool setting and tool breakage detection in three axes. Winfried Weiland, marketing manager at Blum-Novotest, explains: "The TC64-20 is both a universal and a cost-effective system for the automatic measurement and monitoring of tool length, tool radius and tool breakage in CNC machining centres. It is used on machines in many different industrial areas. If several systems, for example a tool setting probe and a workpiece probe, are to be operated in a machine, this is possible, thanks to the BRC Radio Technology integrated within the probe. The TC64-20 is also an excellent solution, if wired devices cannot be attached, for example on machines with pallet changers." The compact tool setting probe boasts fast and robust data transmission. Instead of the channel hopping method or channel assignment commonly used in the market, the TC64-20 transmits the collected data to the receiver using Blum's BRC technology. The advantage of this technology is in the fact that each single 'bit' of the radio signal is transmitted across the entire width of the frequency band, thus making transmission particularly resistant to interference. In addition, a single receiver can be used with up to six Blum radio measuring systems. A further highlight of the TC64-20 is the integrated shark360 technology, a patented measuring mechanism that offers higher measuring accuracy than comparable probes, because of the modified face gear. During the measuring process, the face gear causes a defined deflection direction at constant deflection forces. The torsion force that occurs in the measuring mechanism is absorbed by the gear and, therefore, has no effect on the measuring result. The switch point repeatability is a high-precision 0.4 micron 2s. Another advantage is in how the switch signal for determination of the axis positions is created. It is not generated by a mechanical contact, but instead opto-electronically, by shading with a miniature light barrier inside the tool setting probe. As a result, it is wear-free and guarantees maximum reliability over many years, even under the most adverse conditions. Further advantages of the TC64-20 are the high probing speed, as well as the very low power consumption. Tools of diameter 1 mm can be measured. The TC64-20's self-centring stylus allows a change to be made without re-aligning the probe using a dial gauge. In addition, an optional predetermined breaking point protects the probe system in the event of operating error. The mechanically robust design of the compact tool setting probe is said to be perfectly suited to the harsh environment of a machine tool, boasting device protection to class IP68.
