A table with a rotary fixture is a common device in metalworking. This precision-work tool allows the operator to drill holes or cut at precise intervals on a given axis. The rotary tables can be operated either manually or be powered by the CNC machines. Typically, these tables contain a solid base that has a provision for being fixed to another table.
The exact table is a disc onto which the metal piece to be worked upon can be clamped. Normally, the work piece is centered on the axis of the rotary table. This, in turn, is positioned around the axis of the cutting tool. Thus, a rotary table consists of three axes that are linear or coaxial.
Uses of Rotary Table
The following are the uses of a rotary table:
- drilling holes, small and large diameter ones, at equal distances
- cutting circular pieces with a protrusion
- cutting curves of complex nature as well as arcs
- cutting straight lines at all possible angles
Adding two more axes
If a standard rotary table is designed to have two extra rotary axes, it’s called the 5th Axis Rotary Table. A rotary table with 5 axes can be styled in two different ways:
- by using the rotary tables
- by incorporating the axes of the rotary table into the spindle and headstock of the machine
Advantages of 5th Axis Rotary Table
With two additional axes, the 5th Axis Rotary Table confers many benefits to workers:
- It enables the worker to fix pieces of a complex nature in just one setup. By doing this, the rotary table saves a lot of money spent on machining.
- It allows the worker to use shorter cutting tools. This is because the table allows placing the head towards the task. It also permits positioning of the cutting towards the working surface.
- It enables the worker to machine very complex solid parts, which otherwise would have needed casting.
- In terms of hole drillings, the 5th Axis Rotary Table helps save a lot of time. This is because the head of the device can be automatically oriented along the required axis for each hole.
- Some fundamental machine operations can be programmed onto the device that will hasten work on angular surface.
