About rotary table big

Types of Big Rotary Tables

A big rotary table is a large tabletop-like device that can be rotated to change the workpiece's position during machining. It is primarily used in metal machining factories to hold a workpiece with its larger surface area mounted to a table. These are several types of rotary tables that are commonly used.

  • Direct Drive Rotary Table:

    A Drive rotary table directly connects 3D CNC machines for more straightforward work CNC cutters can quickly accomplish. A direct drive machine has less accuracy, higher spindle speed, and lower costs than other types of rotary tables. Nonetheless, it can do certain jobs directly instead of with an indirect gearbox. Some work is done at higher spindle speeds, so this method is less expensive and faster for some applications.

  • Servo Motor Driven Rotary Table:

    A servo motor-driven work machine has limited speed and lowers work accuracy than an AC motor work machine. A servo motor moves an object in closed loop control by sending commands to the motor driver. The commands include a position where the servo must rotate its rotor and the time duration. It is less expensive than an AC motor-driven machine. Some industries use this because of its lower cost and the jobs its rotary direction can do efficiently.

  • AC Motor Driven Rotary Table:

    This machine can do many jobs and is more accurate than a servo motor-driven machine. An AC motor work machine can rotate a motor speed higher than a direct motor drive motor. An AC motor works by changing the frequency to change how fast the motor turns. It's used when precision is more important than initial cost. Some industries may rent or purchase this work motor for high-precision work requiring its accuracy.

  • Multi-Purpose Rotating Table:

    It is designed to help industries do immeasurable jobs by holding a workpiece with a wide surface area. It has T-slots to anchor a workpiece, douglas hinge positions to locate pieces accurately with down mules, and doubly draped positions to put pieces with an underdrift. Some areas of work that require a multi-purpose rotating table include surveying, metalwork, cutting, and machining. Other industries also do core sample analysis and forensics, and some may use it with small CNC machines when doing those jobs.

  • Indexing Fixture:

    This fixture allows hard-to-reach work areas in an industry to access easily. Some difficult-to-reach work areas include welding, cutting, machining, and assembly. People can quickly reach these places because the fixture holds workpieces securely and rotates them so the user can see all sides, including the underside, while working at comfortable working angles. It improves safety and productivity, as this fixture can be done at a work table or machine.

Specification & Maintenance

  • Dimensional: The dimension primarily focuses on the diameter of the rotary table. Nevertheless, it also includes other related aspects like the thickness.
  • Weight Bearing Capacity: That is another significant rotary table specification, which determines the amount of weight (or heft) that the rotary table can bear. It can range from a couple of grams to hundreds of thousands of pounds.
  • Speed: The speed here talks about the rotation speed of the table. Some rotary tables may rotate at a fixed speed, while others allow different rotation speeds.
  • Accuracy : Accuracy here gauges how exactly a workpiece is aligned or rotated. Generally, the more significant the accuracy, the more expensive the rotary table might be.
  • Control System: A rotary table's control system may be manual or electronic. If electronic, it could be a computer numerical control (CNC) rotary table.

Maintenance

  • Lubrication: Regularly apply grease to the gears, bearings, and sliding parts of the rotary table to maintain its operational performance and stability. When doing this, users have to ensure they employ the right kind of lubricant.
  • Cleaning: Take time out regularly to clean the dirty stuff and debris on the rotary table. One can use a vacuum cleaner or a soft brush to do this. Note that cleaning the debris promptly can help prevent damage to the equipment.
  • Inspection: Carry out regular inspections and look closely at the rotary table for signs of wear, damage, or loosening.
  • Adjustment: Check out the tightness and level of alignment of the rotary table periodically, and perform adjustments as appropriate to ensure its operational reliability and accuracy.
  • Protecting from Dust and Moisture: Dust or moisture can affect the workings of the machinery. So users may have to consider some protective equipment to shield the rotary table from dust and moisture. Alternatively, they could place the equipment indoors.

Usage scenarios

Big rotary tables are key components in the machinery manufacturing industry. They offer the support and rotation speed required for high-precision parts during machining operations.

Plus, they help simplify job setup, making it easier to produce complex pieces without needing as many tools. Machinery manufacturers benefit from these tables, as they help improve product quality while shortening production times.

The heavy-duty rotary table also finds many uses in other industries. Below are some of them:

  • Metalworking Lathes: In this industry, rotary tables are mounted on vertical milling machines, combined mills/drills, or used stand-alone to facilitate machining of irregularly shaped and round workpieces such as pipes, discs, ring etc., to make precise shapes and tracings. This involves making routes, holes, or grooves
  • Toolmaking: these devices are used to make and repair tools and dies. They enable the production of tooling with complex geometries, which would otherwise be impractical with standard machining methods.
  • Fabrication Shops: rotary tables are also common in metallurgy fabrication workshops. They are used for Welding, Machining & Assembly Operations, among many other activities. The tables simplify operations on any workpiece from the metal domain, with precision requirements that cannot be negotiable.
  • Aerospace Industry: In the aerospace industry, big rotary tables are used to work on aerospace parts like airframe components, turbine housings, structural elements, etc. These components require a high level of precision when being worked on so as to maintain the standards and quality set by the governing bodies in the industry to ensure safety standards are always met. Large rotary tables with 5-axis CNCs are preferred for this kind of work because they encourage efficiency and make it easier to achieve higher levels of accuracy and precision when machining aerospace industry components. The cube-swing design allows for multiple parts to be machined at the same time without having to stop often and change tools. The heavy-duty construction means it can handle big jobs, while the through-holes on the table make it easy to hold down even bigger parts any way you'd like. Large CNC machines often use rotary tables with 5-axis CNCs in this industry.
  • Medical Device Manufacturing: the medical device industry usually requires workpieces made of very delicate materials with parts that are often too small and complex to be considered otherwise using the heavy-duty big rotary table. As a result, this industry needs to use high-precision machining of components for medical devices, surgical instruments, implants, etc. in hard-to-reach places. Big precision rotary tables (CNC usually up to 5 axes) are often employed to facilitate efficient production lines for these kinds of devices. Their ability to handle high-speed machining with pinpoint focus and dependability is essential when dealing with small parts with tight tolerance levels and advanced technology requirements.
