RT Cable Plus

In any Rotary Table integration, the importance of a properly designed and installed cable system cannot be understated.  Take a look at the difference between the two rotary table integrations below:

  Our RT Cable Plus Their Cable
Contamination: Zero Contamination:  Our RT Cable Plus contains motor, I/O and shielded encoder conductors in a single PVC jacketed cable.  The cable is highly flexible, durbale, resistant to coolant contamination and protected by strain relief on both ends (a steel-braided version is also available on request). Risk of Contamination:  Traditional sealtight cable is susceptible to cracking and splitting when exposed to some coolants and continuous flexing.  Over time, cracking and splitting will lead to higher failure rates.                                                                                             
Connection: Our RT Cable Plus system is hard-wired to the rotary table which eliminates a potential contamination point.  A single environmental quick disconnect connector is used to interface the table to the machine.  This allows the table to be connected/disconnected with one quick turn. Their sealtight connections on the back of the rotary table create additional potential contamination points.  These threaded connectors also make connecting and disconnecting the table a time-consuming and difficult process.
Cable: One cable, rather than two means fewer connection points, less wear and lower contamination risk. Two cables can create a tangled mess, which can cause premature wear.  Two cables require four connections and four-times the chance for contamination.
Location: The RT Cable Plus connectors are located away from chips and coolant and we add a spring management system to help minimize cable wear. Locating the connection points close to coolant and chips creates a greater chance for failure, as traditional sealtight will collect coolant.  Furthermore, the cables could easily be pinched during machine movement or part loading.
