Readers ask: What Is A Rotary Table Used For?

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis.

When should a rotary table be used?

Rotary tables are used for precision metalworking. They are typically made with a solid base that can be clamped on to another fixture. The table is a disc that rotates freely or by use of a worm (hand crank).

Do I need a rotary table?

A rotary table is indicated when certain types of complex cuts, especially cuts of a rotary nature, are required during milling. Ordinarily this would require the workpiece be moved from the mill to a lathe, clamped/chucked and then turned, then moved back to the mill.

What are the advantages of using rotary layout?

There is the flexibility of changing the tooling to accommodate new variants. A rotary assembly system can replace some or all manual labour allowing production running costs to be reduced. Additional benefits include that the operations can be quality assured and checked automatically.

Can you use a rotary table on a lathe?

A lathe chuck can be mounted on the rotary table to hold cylindrical objects. Make or purchase an adapter plate to mount the chuck. When working on relatively long cylindrical objects, you might need to support the end of the workpiece. A tailstock provides the required support.

Can a dividing head be used as a rotary table?

No, not the same. Though they both do similar jobs. Some rotary tables can be converted to dividing heads.

How accurate are rotary tables?

The table offers an accuracy of 2 13 arc seconds with a backlash of about 10 arc seconds. Both lines show a similar long-range error that is caused by the geometric errors of the worm wheel and possibly by an eccentric mounting of the wheel.

What is a rotary table on an oil rig?

1. n. [Drilling] The revolving or spinning section of the drillfloor that provides power to turn the drillstring in a clockwise direction (as viewed from above).

What is kelly bushing in drilling rig?

1. n. [Drilling] An adapter that serves to connect the rotary table to the kelly. The kelly bushing has an inside diameter profile that matches that of the kelly, usually square or hexagonal. It is connected to the rotary table by four large steel pins that fit into mating holes in the rotary table.

What does a dividing head do?

An indexing head, also known as a dividing head or spiral head, is a specialized tool that allows a workpiece to be circularly indexed; that is, easily and precisely rotated to preset angles or circular divisions.

What is automated flow line?

An automated flow line consists of several machines or workstations which are linked together by work handling devices that transfer parts between the stations. The transfer of work parts occurs automatically and the workstations carry out their specialized functions automatically.

Which type of machine is used in process layout?

All machines performing similar type of operations are grouped at one location in the process layout e.g., all lathes, milling machines, etc. are grouped in the shop will be clustered in like groups. Thus, in process layout the arrangement of facilities are grouped together according to their functions.

What are the disadvantages of product layout?

Product Layout: Possible Disadvantages: (1) None or very little variety possible. (2) Less flexibility to changes, particularly to other than minor changes. (3) Entire line or significant portions of the line may come to a grinding halt if any equipment in the line breaks down, resulting in high stoppage costs.
