Although the factory handicraft industry is relatively backward, it has trained and brought up many skilled workers. Although they are not experts in manufacturing machines, they can manufacture various kinds of hand tools, such as knives, saws, needles, drills, cones, grinders, shafts, sleeves, gears, bedsteads, and so on. In fact, machines are assembled from these parts. Da Vinci, the early designer of boring machine. Boring machine is known as "the mother of machinery". Speaking of boring machine, we have to talk about Da Vinci first. This legendary figure may be the designer of the boring machine used for metal processing. The boring machine he designed is powered by hydraulic power or pedal. The boring tool rotates close to the workpiece, and the workpiece is fixed on the mobile platform driven by the crane. In 1540, another painter painted a painting of "Pyrotechnics", which also had the same boring machine drawing. At that time, boring machines were specially used for finishing hollow castings. The first boring machine (Wilkinson, 1775) was born for the processing of cannon barrel. In the 17th century, due to military needs, the artillery manufacturing industry developed very rapidly. How to manufacture the barrel of the artillery became a major problem that people urgently needed to solve. The world's first real boring machine was invented by Wilkinson in 1775. In fact, to be exact, Wilkinson's boring machine is a kind of drilling machine capable of accurately processing artillery. It is a hollow cylindrical boring bar, with both ends installed on bearings. Wilkinson was born in the United States in 1728. When he was 20 years old, he moved to Staffordshire and built the first iron smelting furnace in Bileston. Therefore, Wilkinson was called "the blacksmith master of Staffordshire". In 1775, at the age of 47, Wilkinson made continuous efforts in his father's factory and finally produced this new machine that can drill the barrel of a cannon with rare accuracy. Interestingly, after Wilkinson died in 1808, he was buried in a cast iron coffin designed by himself. Boring machines made important contributions to Watt's steam engine. If there were no steam engine, there would be no wave of the second industrial revolution at that time. In addition to the necessary social opportunities, the development and application of the steam engine itself also have some technical prerequisites that can not be ignored, because the manufacturing of steam engine parts is far from as easy as the carpenter cutting wood. It is necessary to make metal into some special shapes, and the processing accuracy requirements are high. It is impossible to do without corresponding technical equipment. For example, for the cylinder and piston of steam engine, the precision of the outer diameter required in the piston manufacturing process can be measured from the outside while cutting, but to meet the precision requirements of the inner diameter of the cylinder, it is not easy to use general processing methods.
