Pneumatic Collet Chuck Provides Rotary Table Solution

The aim of all manufacturers is to streamline the machining of parts and make the process as uncomplicated as possible.  However, some components can be more complex to produce than others and the rotary table being used will have to reposition the object several times before the procedure is completed.  In such complex applications it is wise to keep the work area around the rotary table as clear as is possible.  At Kitagawa we offer optional built-in rotary joints that can help achieve this goal.  Here we take a look at the TT182 rotary table complete with built-in rotary joints, which can be used in conjunction with a variety of pneumatic collet chucks to produce a wide range of parts. 

Rotary joint operation

The purpose of the rotary joint is to provide air or hydraulic pressure from the rear end of the rotary table to a fixture.  In this case the purpose is to supply pressure to the pneumatic collet chuck via air pipes. 


In the image above we see the TT182 with the built-in rotary joints circled in red.  By connecting a pneumatic pipe from the side rotary joint to the backend rotary joint, the collet chuck can be actuated.  The ability to take such an approach to collet chuck actuation means that less pipe work is needed.  The result is a much cleaner and simpler working space, which negates the problem of pipe work getting in the way during operation.  This in turn serves to remove the likelihood of an interruption in production, which of course assists in the continuation of a smooth and cost effective manufacturing process. 

Additional benefits

Built-in rotary joints are by design more compact than external options.  Much of the rotary joint is housed within the rotary table itself.  In comparison external rotary joints protrude further out of the back of the rotary table, as can be seen in the image below.


Therefore, built-in rotary joints are best suited to applications where there is only minimal clearance available at the back of the rotary table.  In contrast, external rotary joints have more ports in the event that many pneumatic and hydraulic pipes are required.   They also have the ability to operate at a much higher pressure than built in rotary joints.  In conclusion, both external and built-in rotary joints have their own advantages and disadvantages, which should be considered in relation to each individual application.
