A Brief Overview Of The Tilting Rotary Table
A tilting rotary table is designed to allow a piece of material to be moved vertically in relation to another piece of material that is stationary. Typically, most rotary tables are used for table top deburring as well as other types of turning operations. The operation done on such a rotating table is very similar to that done on a lathe. Usually a tilting rotary table will be tilted in relation to another stationary table to allow it to rotate vertically through the range of the table. On a tilting rotary table, the rotating shaft of the table is driven by a counter-weighted worm and screw, meaning that the work piece can be simultaneously machined during both of these motions.
One of the first types of tilting rotary tables was patented in 1976 by Albright andenser. Since that time there have been many manufacturers that have designed and produced specialized tilting units that offer various types of operations. In addition to these manufacturers, there are many individual hobbyists that are making and using their own specialized units. Regardless of the type of material being used, there is likely a rotating mechanism that will be suitable for the operation that will be required.
One type of tilting rotary tables that are commonly used is one that is similar to a horizontal lathe. These units can either be made up of steel or aluminum and feature a fully adjustable horizontal axis. The fully adjustable horizontal axis allows the user to provide a variety of motion options. Some tilting rotary tables feature two independent movement directions while others feature one fixed direction.
While some tilt-able units feature mechanical spindles that rotate on two independently moving axes, there are also those that feature a single stationary, fixed rotary shaft. Some tilting rotary tables allow for adjustments in the length of the shaft, which is useful in applications where the item being worked with needs to be held at different heights. In some cases the height can even be controlled on the fly. Most units however feature a fixed, non-adjustable length that can usually be locked in place.
As is the case with many other rotating mechanical pieces, the materials that are used in tilting rotary tables are widely varied. Many units are constructed from high quality stainless steel, while others are constructed from a variety of high performance aluminum alloys. Aluminum alloys have many advantages over the stainless steel option. They are lighter than most steel alloys and they are much more resistant to corrosion. An aluminum tilting rotary table often features an angle plate that locks in the proper angle and prevents the unit from tipping over.
The milling machine attachment for a tilting rotary table unit is designed to be quick and precise. Many models offer an ability to quickly adjust the length of the head or the length of the divide and, in some cases, both of these adjustment heads can be moved independently. In some tilting units a user may also be able to program the exact sizes of the heads or the sizes of the sectors. This allows users to vary the size of the piece they are working on without having to wait until they have completely finished making the necessary adjustments. In addition some tilting divide units have a built in error check and recovery mechanism that allow for a user to easily correct errors when they occur.
