Boring Mills: A History

Boring mills or boring milling machines are used to machine or bore any solid material (typically a metal, plastic, or wood) or they are used  to increase the size of an existing hole. These machines are classified into two types, horizontal and vertical boring mills. Both types vary in sizes and can be used to bore from a small device to devices which can be as big as a room. They also can be classified on the basis of power and sizes.

The working of boring mills is slightly different from that of drill machine. The drill machine holds the work piece stationary while penetrating the material. But in case of boring machines the work piece is also moved against the milling cutter. This results in cutting from the sides as well as from the tips of the material. The movement of cutter and work piece is controlled by the lead screws. These machines are operated manually as well as automatically.

Their main purpose is to bore a solid material. They are used to penetrate into a solid object to make a hole or increase the size of the hole. This operation can be very simple but when it comes to bore the heavy materials, it can become very complex.

Boring mills were first introduced in the beginning of the 18th century. The purpose behind their introduction was to machine the objects quickly and easily as it was very hard to bore the solid object with hands. The early boring milling machines were very big and complex and they were not that effective. People continue on working for the advancement and by 1860 a person named Lincoln Miller came up with an advanced idea. The idea was to set up in position first and then run the machine. The advanced search continued through World War I and World War II and during this period people came up with the horizontal and vertical machines. Until 1970 these machines were manual or mechanically automated but in 1970 these machines were made digital automated and they were controlled by computer and CNC tools. After that work is only done for the advancement of digital automated machines.

Boring mills that appeared in 18th century are far removed from the boring milling machines we have now in purpose and application.

great history on boring mills. boring milling machines are integral to modern manufacturing so it's fun to read the history of these milling machines.
