Precision Rotary Tables for Your Applications

Precision Rotary Tables for Your ApplicationsMany applications can benefit from the use of a precision rotary table. This allows for a device to be accurately positioned according to a precision gear structure. A stepper motor or servo motor can be attached, which provides torque with an accuracy of 12 arc-minutes and a +/- 3 arc minute with repeatability. This can be done either horizontally or vertically. Precision rotary tables can be adjusted with plates that make it easy to see where the intervals are. Plates can also be different sizes, allowing for use with smaller or larger applications. The tables can be manual or powered, and powered tables are usually controlled by CNC machines, making them accurate and automated.

Some of the industries in which a precision rotary table can be used include pharmaceutical packaging, electronic component manufacturing and positioning, grinding, automotive automation, homeland security, aviation, filming, robotics, and more.

Prime Drives precision rotary tables offer the most options in the industry for acquiring the correct gear ratios and table for your needs. The world leader of this industry, Prime Drives provides precision rotary tables that have the largest quantity of options for clients, which sets the company’s product apart from its competitors’.

It is important to select the correct table for the application, as attempting to use a smaller table for an application that involves large or heavy parts can damage the table and result in parts that are much less than the precision intended, including rough finishes on the surface and features that are out of tolerance. Knowing the needs of the project and the capacity of the table will aid you in acquiring the precision rotary table that will handle your application with the most accuracy and best precision.

Some uses of a precision rotary table include machining spanner flats on bolts, drilling holes equally around a round flange, cutting a round piece with a tang that protrudes, milling helixes, cutting complex curves, cutting straight lines at an angle, cutting arcs, cutting circular pieces, and more. Bolts and screws are ideally done with one of these, for example.

Rotary Servo – Do You Have the Right One for the Job?

Do you have the right Rotary Servo for the job you have to do? Prime Drives manufactures Rotary Servos and will work closely with you to ensure you have the right Rotary Servo for your application needs. Before deciding if you have the right one, however, it is important to understand what a Rotary Servo is, what applications they might be used for, and what benefits you can receive from using Prime Drives’ Rotary Servos.

What is a Rotary Servo? Also called a Direct Drive Servo, a Rotary Servo is a precision rotary positioning device. It is most often used in robotics, for antenna pedestals, and in medical patient beds. Rotary Servos are also used in machines which automate the placement of integrated circuits, capacitors, resistors and diodes. These are then placed on printed circuit boards and will become computer motherboards as well as the brains behind today’s top smart TVs or your iPad.

What applications use them? Rotary Servos are used in the following applications:

  • Automated pick and place machines
  • Machine tools
  • Robotics
  • Visual inspection machines
  • Medical patient beds for oncology detection and treatment
  • Entertainment/film industry for cameras
  • Military applications would include gun turrets on helicopters and tanks as well as cameras on unmanned aerial vehicles (UAVs)

Why would someone choose one type of Rotary Servo over another? Basically, Rotary Servo is a general term. It can be applied to any of the following: Direct Drive Servo, Parts Sets Servo, or simply a basic rotary table driven by a servo motor. The type of applications for which the Rotary Servo is needed will determine the type the engineers select.

How are the Rotary Servos from Prime Drives different from the competitors? What are the benefits of using them?

  • We have designed our Rotary Servos to be flexible offering more gear ratios and diameters than others available in today’s marketplace. This is what distinguishes ours from our competitors.
  • We design our Rotary Servos with four distinct diameter tables. These range from 4 inch diameter to 12 inch diameter. There are 24 various ratios within each of these diameter series.
  • We offer customization of the table. This can include a machined top plate which eliminates the need for an adapter plate. We can also add custom home sensors. Customization can also be made for the thru hole. This customization alleviates cable management issues or allows for laser pass thru capability.

Achieving Accuracy with Direct Drive Rotary Stages

Achieving Accuracy with Direct Drive Rotary StagesDoes your application require an unusual level of precision? Does your current Direct Drive Rotary Stage meet your current torque requirements? If your answers to these questions was “no,” Prime Drives can design and manufacture Direct Drive Rotary Stages to meet your specific positioning needs.

Direct drive rotary stages can be designed with apertures of nearly any diameter and load capacity. Your application will determine the aperture size and load requirements.

Possible applications might include rotary testing, optical calibration, inertial navigation, electro-optic sensors (single or multi-axis), or antennas. Many fields require precise angular positioning including various electronic assemblies, medical, pharmaceutical, robotics, fiber optics, research institutions, microelectronics, photonics and defense and security.

How does a direct drive rotary stage help with accuracy?

  • Reduce or eliminate backlash
  • Better positioning accuracy
  • Increased speeds
  • Maximize performance related to tilt error
  • Reduce rotating friction
  • Eliminate wear problems connected with belt drives, worm-drive and gear-drive rotary stages
  • Reduced travel
  • Increased repeatability

An added benefit of this type of rotary stage is that it lasts longer and requires less maintenance than other rotary stage types. If space limitations are a factor, Prime Drives is able to design a Direct Drive Rotary Stage to fit within those constraints with a low profile, high precision design. with heights as small as 40 mm.

Aperture size needs may vary depending upon your application. Some factors to consider are the number of wires or vacuum lines routing through the aperture. We can design Direct Drive Rotary Stages with aperture sizes ranging from 10 to 300 mm. For more specification details refer to our product brochure or call our office at 775-333-5984.

Depending upon your specific requirements, often dictated by your industry, our team of experts can design the best possible solution for your company and your application. Whether your Direct Drive Rotary Stage needs are simple or very complex, our engineers will work closely with you to design equipment that will meet those needs.
