Walk into a modern machine shop and it’s easy to be overwhelmed by the amount of advanced technology on display. CNC machines rely on computers and G-code to perform advanced cutting operations on 5-axis machines, or Electron Discharge Machines (EDMs), which use electricity to cut through metal parts.
It can also be overwhelming when looking into a metal working lathe for sale. There is a lot of knowledge that goes into understanding lathes and what to look for when buying one. Here at Summit, we are available to help you find the best metal working lathe for sale that will fit your needs.
It is interesting to note, that despite the advanced technology, all of the machining processes used today are rooted in much older principles. The history of the lathe, one of the most significant machine tools, is a good example. An important part of this history is looking at when was the lathe invented?
Early lathes: from wood to metal
Machining is the process by which a piece of raw material is cut and shaped into the desired form. Most machine tools rely on subtractive machining, removing material by cutting or grinding. Various kinds of machine tools have been in use for centuries or even longer.
The metal lathe is one such machine. So when was the lathe invented? Evidence for the earliest metalworking lathes comes from Egypt, where metal-spinning involved two people and a rope-wound spindle. Only pictorial evidence survives, leaving speculation about how the earliest lathes worked.
In the ensuing centuries, many cultures used variations of metal-spinning, although until the late Middle-Ages there was no continuous motion on the spindle. This meant that the cutting wasn’t continuous; it would start, stop, and reset as the workpiece turned.
The oldest modern lathes were used for woodworking and probably originated in France in the 1500s. These lathes were continuous-motion, as foot pedals came into use. The lathe machining process became known as “turning.” Turning on a lathe had major advantages; the rotation allowed the material to be removed evenly. Early metalworking lathes were operated by a foot pedal or hand crank and a lathe operator could control how much material was removed by increasing or decreasing the speed of rotation.
With a wood lathe, craftsmen could create table legs and other cylindrical shapes far more quickly than they could be carved by hand.
Who invented the metal lathe?
The question, “when was the lathe invented?”, can also point us to the beginning of the Industrial Revolution in England when a handful of inventors made discoveries that became foundational to the technological advances that would follow. Henry Maudslay was one of those inventors. Born in 1771, he worked first for a locksmith and then went into business for himself, manufacturing ship’s machinery – pulleys and block-and-tackle.
For the next three decades, Maudslay invented several machines and taught other notable inventors and engineers of the Victorian era. One of Maudslay’s most significant inventions was the metal lathe.
Lathes had been used to cut metal before; there was nothing fundamentally different between early metalworking lathes and wood-turning lathes, other than perhaps the materials used to make it. Before Maudslay, workers turned metal and used freehand tools to shape the workpiece. This worked, but the resulting pieces were uneven.
Around 1800, Maudslay hit on the idea of fixing the cutting tool to sliding rails. By moving the tool smoothly along the length of the lathe, cuts could be made evenly. Maudslay used his invention to standardize the size of screw threads which allowed screws to be mass-produced and used interchangeably.
The importance of the metal lathe
Early metalworking lathes didn’t single-handedly start the Industrial Revolution, but was one of the major contributors to mass-produced, interchangeable parts. The lathe was then coupled with the steam engine, which allowed the large-scale turning of metal parts.
Maudslay’s early metalworking lathe also proved crucial to the growth of other machine tools. His lathe demonstrated that new methods of construction could be combined to produce new tools and use them with new materials.
Metal lathes today
The revolution of the Age of Computers has also transformed the metal lathe. More advanced lathes today are equipped with Computer Numerical Control (CNC) technology. Using a computer language known as G-code, CNC lathes can be pre-programmed to cut an entire series of parts to the same dimensions.
Modern lathes use the same basic principles as Maudslay’s lathe of 200 years ago, and perhaps of lathes that are much older than that. They are one of the most important machine tools in widespread use today.
