Rotary Table Accessories: We maintain a stock of the most popular accessories for TJR rotary tables and indexers, including tailstocks and indexer controls. And with worldwide connections and resources, if we don’t have the accessories you need on hand, we can find them.
CNC Indexing & Feeding Technologies offers a wide range of TJR rotary tables. However, many are unclear about what rotary tables can do for their business, as well as how they work in CNC machining. First, let’s consider the basics about a rotary table and how it works in the machining and manufacturing processes.
What is a Rotary Table and What Does It Do?
Milling and other industrial processes require cutting and shaping, usually with a high degree of precision. This creates the need for computer-guided systems that can create workpieces, prototypes or tools for companies on demand. The process is expedited and can be completed quickly, reducing or eliminating the need for large assembly line staff or other hand crafters.
In many cases, the work pieces created through CNC machining would be impossible without computer assistance. The code used to communicate between the CNC machine and computer software is specialized. Older machines, or manual-controlled machines, used hard wired controllers. However, new CNC machines rely on modern devices like CDs, USB drives, networks and so on.
A lathe or milling machine requires its own set of parts to work sufficiently. For example, an indexing head is needed to allow circular shaping. The indexing element allows the piece to be rotated at an angle or even divided into sections. A rotary table can tilt and rotate. The table makes use of the indexing head in order to cut according to a specific technique. This function lets the machine create a workpiece with complete flexibility in rotation and angling that ordinarily wouldn’t be possible with handcrafting.
Manual and CNC differences simply involve the old world CNC machines, operated by levers, versus the new models which are controlled by Computer Numerical Control, usually software programs that manipulate the moving parts — and lend to the machine an ability to cut precise parts. Thus, a CNC rotary table is one that is controlled through a computer automatically.
How and Why Are Tables Used?
A rotary table can help to create arcs and circles, an important process in part or tool fabrication. Tools can be specially made, such as car parts, machine parts, and many other objects that a wide range of industries use day in and day out. The computer-aided process lets companies make straight cuts even amongst multiple angles, or to cut already small objects into even smaller parts. Machine rotary tables can also help in the processes of cutting gears, drilling or cutting holes in a part, or drilling holes in selected areas.
The rotary table can also be used along with a dividing head and index plate, to further concentrate the shaping. Tables are also used to hold certain parts for superior milling techniques.
With the addition of rotary tables, you will have a greater capacity to produce the parts you want, that are most profitable. This brings us to the primary advantage of CNC rotary tables: less time and greater accuracy in cutting.
Who Uses CNC Machines and Rotary Tables?
Companies are often outsourced to create work pieces for larger brands. However, some companies simply create their own prototypes, tools or work pieces with their own facility for machining. There are also contract shops, mechanic shops, electronics companies, inventors, engineering, and retail companies.
Whenever there is a new product, rest assured it never sees the light of day until it goes through an excruciating process of testing, documenting, and the creation of prototypes. This is another area in which CNC rotary tables are used.
Most companies do not have huge resources, warehouses and capital to fund major assembly lines and so they will scale their needs with small productions. In many cases, they may only have one facility or work with one type of part. The key is not to create “anything” but to specialize in objects created so the process can be streamlined.
Rotary tables offer the benefits of efficiency and accuracy for all these industries and tasks.
Benefits of Using Rotary Tables Through CNC
The benefits come not only in variety but also in enhanced capacity. A production company can save money by taking on outsourced production processes and using minimal resources to create the work pieces in bulk. The cycle and process will be created to match the resources on hand as well as the requested volume.
The benefits of using higher powered and enhanced machines through CNC include consistency, as well as faster production. Products and work pieces assembled through computer-aided systems are statistically more reliable than products created manually or through other methods. The process is identical each and every time and thus consistency in design can be guaranteed—major importance to a company trying to ensure safety protocol.
Flexibility is another advantage, as the systems are programmable. These systems are actually designed to minimize downtime in between their running processes. The newer systems’ flexibility is greatly preferred by companies that dread having to install and uninstall huge systems of yesterday that take up too much space. The capacity of complexity of product is another benefit. Complex motions made simpler by CNC rotary tables not only make greater products available and more affordable to produce; a major advantage for industrial and retail businesses hoping to keep prices low.
How Workers Interact with CNC
Naturally, such an intricate process cannot be unsupervised, since efficiency depends on optimal performance. Managers and supervisors are needed to oversee a machine rotary table operating with CNC controls, ensuring the machine and the software are configured correctly.
This involves setting the system up, installing the software, and watching over the production. If something goes wrong, the software must be fixed and the machine repaired. Machines are not constantly running, but must be evaluated and cleaned regularly, ensuring that they will be mostly self-sufficient.
Types of Tables You Might Need
There is a variety of table types you might find useful to work with, and we can meet all of your needs. We work with standard rotary tables with full rotating axis capabilities, and vertical and horizontal mounting positions.
We also offer large rotary tables with hydraulic brake systems, which allow higher clamping torques. You can also find assistance with smaller rear mount rotary tables or tilt rotary tables.
Horizontal rotary tables are specially made for horizontal mounting and carrying a much heavier weight. Horizontal index tables are available, whether in manual or CNC index tables style. Finally, there are face gear rotary tables and rotary table accessories, ideal for projects that need higher degrees of accuracy.
Remember that quality production is synonymous with efficiency and accuracy. Product producers must have the right equipment operating at full capacity in order to guarantee consistency — and in the end, their success.
CNC Indexing & Feeding Technologies can help you find the CNC rotary tables, indexers and other accessories you need to meet your production demands, from simple rotating feature (with a scalable and small setup) to larger work pieces, vertical and horizontal applications, or even 4 or 5 axis work. We are confident that by utilizing Ganro Industrial Corp. rotary tables, you will be able to improving your cycle and process time, reduce your down time and increase your profits.
