Excerpt from Drop Forging, Die Sinking and Machine Forming of Steel: Modern Shop Practice, Processes, Methods, Machines, Tools and Details
The hot and cold shaping, squeezing, forming, and bending of duplicate metal parts and high-speed steel cutting tools by forging in drop-dies, drop-hammers, steam-hammers, hydraulic presses, and forging-machines, are becoming more appreciated by the most advanced manufacturers and mechanics; but, until the publication of this work, to the average mechanic familiarity with the advanced shop practise, tools, and processes has been denied, because of the almost total lack of descriptive practical literature, and also the conservatism of manufacturers and experts in publishing their shop-practise and knowledge evolution. Therefore, to make possible among mechanics a broad and comprehensive knowledge of these arts I present this book, hoping it will find a valuable and permanent place in its field.
