How a Direct Drive Rotary Table Operates
Rotary or Direct Drive Rotary tables are a popular choice for many different applications. These types of tables are designed to allow users to operate on a flat or angled surface as opposed to using a table that needs to be turned on its side to face the work surface. Direct drive rotary tables have the motor built right into the bottom of the rotary table faceplate directly driving the bearings and axes. The tables offer very high speed and high acceleration/deceleration capabilities for designing intricate complex shapes and forms.
The table is able to run at extremely high torque due to its high angular momentum. Because of the high torque the table is able to run at a faster rate than other common table designs. These high torque motors typically only need a few brushes to create a high torque brushless motor that greatly reduces the size and weight of the overall structure. The small size and weight allow direct drive rotary tables to use a variety of accessories which allow users to customize the surface and design to their specific needs.
One of the most common features found on direct drive rotary tables is its ability to use high speed CNC milling software with its numerous programming options. This allows the table to quickly and accurately perform any required operations. This feature is referred to as the “high speed” CNC milling software. CNC milling software allows users to design, build and fine tune any CNC machine or robot with ease and accuracy.
High speed CNC milling software is available in two forms which are designed for the PC and the Mac. Due to the increased complexity of the PC based designs it is often used to create precision machining products such as die cast vehicles and precision die structures. Because of the increased cost associated with utilizing PC based designs much more people are turning to the alternative option of direct drive rotary tables. Direct drive rotary tables are much smaller and much lighter than their CNC counterparts.
The biggest advantage of the direct drive rotary tables is its ability to produce high accuracy results without the use of expensive machining methods. One example of this is how the material is fed into the table and precisely ground to create the desired profile or contour. A CNC milling machine would need to use more expensive milling techniques to create the same exact result. A direct drive rotary table is also able to use a variety of accessory drives such as a variable angle gear caddy which is fed into the table. This feature can greatly improve the accuracy of the device and allows the user to fine tune the milling operation without affecting any of the other components.
In order to improve the overall accuracy and efficiency of the product it is necessary to control both the operating speeds and the clamping system. This is achieved with the use of a suitable PC board or a suitable clamping system. Both types of controls will provide the user with a range of different options. It is common for high speed and high index CNC lathe systems to use a PC board which is attached to a clamping system via an indexing slide or spacer. A suitable spacer can be selected which will match the needs of the project and the most efficient CNC clamping system will be able to provide this range of options.
