In the process of invention, many things are often complementary, interlocking: in order to create a steam engine, the need for a trampoline to help; after the invention of the steam engine, from the process requirements and began calling the planer. It can be said that it was the invention of the steam engine that led to the development of the “working machine” from the trampoline, lathe, and planer. In fact, the planer is a planer metal.
The planer for large plane machining (1839) Since the beginning of the 19th century, due to the plane machining requirements of steam engine seats, many technicians have begun research in this area, among them Richard Roberts, Richard Pratt, James Fox and Joseph Clement et al., who from 1814, independently produced the planer for 25 years. This type of planer is to fix the processing object on the back and forth platform, and the planer cuts one side of the processed material. However, this type of planer has no delivery device and is in the process of transition from "tool" to "machinery." By 1839, a British named Bommard finally designed a planer with a knife delivery device.
A small planer for facets Another Britishman, Smith Smith, invented and manufactured a faceted planer for 40 years from 1831. It can fix objects on the bed and the tools move back and forth.
Since then, due to the improvement of the tools and the appearance of the electric motor, the planer has been developing toward high-speed cutting and high-precision, and on the other hand, it has grown toward large-scale.
