A CNC Rotary Table is a table used in manufacturing to create detailed cuts and contours. The benefits of such a table include ease of assembly, easy operation, lower operating costs, and minimal labor and workload. A common rotary table used in manufacturing can handle basic cutting jobs including drilling, grinding, boring, smoothing, buffing, and turning. These are just some of the various operations which can also be done on a rotary table.
CNC rotary tables come in different shapes and sizes, with some having up to 15 inches of depth. Some have features like an adjustable sloping diamond bed which allows for the attachment of accessories on its top. There are even CNC machining centers, which are equipped with diamond plate and a robotic arm. This enables the operator to move and cut various shapes using the diamond plate as well as the robotic arm.
Before selecting a CNC rotary table, it is necessary to understand the different types of operation which can be carried out with this type of machinery. These include the wet milling and dry milling operations which are commonly carried out on this equipment. Wet milling involves the use of water to induce steam through the material being cut to a shape, while dry milling uses electric pressure to grind or press the material directly. As previously mentioned, these operations can be carried out manually or by automated machinery depending on the requirements. However, different types of machines need to be selected based on their operating principles and the requirements of the customer.
An important factor to consider when making CNC Rotary Table selection based on specifications is the mechanical design. The torque, feed rate, speed, operating principle and the type of material to be used are some of the factors which need to be considered in the overall selection. The most common types of CNC Rotary Tables are those which are designed for simple surface applications. Their indexing accuracy, mechanical design and overall performance can be affected to a large extent by the design of the axis and the interface of the spindle with the chuck or rotor.
A CNC rotary table with a higher level of mechanical efficiency is required to execute tasks which require an extremely high level of accuracy. Feed rates and speeds also have an impact on the accuracy and efficiency of the CNC milling machine. A CNC milling machine can only operate at faster speeds when the axes of the machine are at higher levels of angular velocities. This is achieved when the 4th axis rotary table is placed close to the work piece. This results in the machine’s torque and feeding rate being increased, which allows it to execute tasks more quickly.
CNC rotary tables with higher level of mechanical efficiency requires more manual machining effort than conventionally powered CNC machines. They also tend to generate more heat under higher load conditions. They require a higher level of precision machining operation as well. The combination of these factors leads to a reduction in the life span of the CNC rotary tables and an increase in the wear and tear of the operator. The use of high precision CNC axis with larger axes and a better indexing accuracy improves the overall efficiency of these machines, which results in a reduction in operating costs as well.
