Renishaw's RLP40 and OLP40 lathe inspection probes offer a choice of radio or optical signal transmission technologies to make part setup and inspection on turning centers accurate and reliable. Measuring 40 mm in diameter and 58.3 mm long, the probes provide uni-directional repeatability of 1 micron and can be used to reduce setup times, scrap and fixture costs while improving process control, the company says. Both designs are hardened and sealed to IPX8 to withstand the extreme environments typical of lathes and turning centers. An eyelid protection system prevents entry of chips and debris that could damage probe internals.
 
The RLP40’s frequency-hopping spread spectrum radio transmission pairs with the company’s standard radio machine interface and utilizes the 2.4 GHz frequency band. The probe and its interface continually hop from one transmission channel to another, delivering signal robustness and flexibility through frequency switching. Radio transmission allows continuous communication between the probe and the interface, even when line-of-sight is lost.
 
The OLP40 uses modulated optical transmission for high resistance to light interference, and its 360-degree transmission systems allows the probe to operate in any orientation. It also works with the company’s legacy transmission systems, while two touch probes can be used on one turning center when the OMI-2T interface unit is used.
 
A wide range of shanks is available, including parallel and tapered designs, for maximum flexibility when mounting the probes in a lathe or turning center turret. RMP40M and OMP40M transmission-only modules are also available to enable the use of the company’s LP2 family of touch probes and accessories to reach part features that would otherwise be inaccessible.
