The milling-boring machine is an invention which was developed in 1825 by William Hunt and William Croft. The two inventors worked independently on this and neither believed that it would succeed. Their concern was the price of a machine and they both realized that this might be impossible to get a machine for a very low price.
It wasn’t until the industrial revolution did their concern for cost ease to the modern business take effect. Both worked in the construction trade and understood the skill required to build the famous saw mills. They worked out that a spiral saw had to be laid out into a very accurate circle, of the sort with a cross section of twelve inches. Then a special tool to cut a sphere of high strength in half would have to be manufactured.
An early attempt was made in 1840, but it was not as successful as the reason that there was not enough hard wood to work with, and the ‘whittled steel spheres’ were not smooth enough. The companies were willing to give the job away, however, and it was produced. This tool proved that they could create a better milled product using modern equipment.
Wholesale manufacturing of milled products was then the focus of the company’s attention. They began to use the cutting machine in a number of different ways. At first, the tools were used to carve large blocks of wood for sawmills.
As milled products became more popular, the need for a new cutting tool was felt. There was a different type of tool which cut straight edges with a speed of fifty-eight miles per hour. This was the first automatic milling machine.
The cutter used a rotating drum with revolving blades. The object to be cut had to be brought into the drum to prevent a great deal of pressure from moving against the blade at high speeds. It was found that the first milling machines had to be rotated manually every few seconds in order to perform well.
The cutting machine was now being produced in a number of forms. They were used to make sieves and measuring devices. Milling machines were also used to build and shape metals. However, the products that made up this industry were not generally good quality.
Milling machines were also used in building and carving machinery. The use of this type of cutting machine was ended because the machine could not be made in a number of sizes. There was also a problem when the machine got hung up and stopped working.
