In the development of human industry, conventional lathes have played an important role in history. The conventional lathe is an ancient turning machine, which has high productivity and can handle many types of machining tasks in many ways. First, conventional lathes were developed from conventional manual processing of spinning cutting art works about 4,000 years ago. In the early 20th century, the development of this particular type of lathe became very specific, and later there were computer programs. Even ordinary conventional lathes are now equipped with CNC systems.
Why Not Manually Solved?
As people have discovered, the manual operation of machining is not much different from the technology of turning equipment. Due to the inconvenience of equipment preparation, the development of ancient lathes was not considered important.
Later, because of the increase in manpower, the power supply problem was solved. More and more labor can devote themselves to supporting the rotating loads of lathe operations. In other words, although the processing technology is profitable, it requires certain conditions to promote its development.
Types of Lathes
In the industry, the types of lathes are very wide, each of which has different uses, and some functions may overlap. The following is an introduction to some lathe models.
Swiss Type Lathe
The Swiss type lathe is a specially designed lathe that provides extremely high standards of accuracy and precision and handles turning tasks in a specific way. Swiss-type lathes use chucks and guide bushes to secure the workpiece. The collet is located behind the guide bushing, and the tool is located in front of the guide bushing, which usually remains stationary on the Z axis. To cut along the longitudinal direction of the part, the tool will move inward and the material will move back and forth along the Z axis. This action design allows all work to be done on the material near the guide bushing. Because the guide bushing is hard, it is very suitable for processing slender workpieces.
Turn and Mill Machine
Based on this function, turning and milling machines are also called CNC turning centers. It is a machine tool that has both turning and milling functions, as well as rotating workpieces on a rotary axis to perform various machining operations, such as cutting and turning. This type of machining task is performed by the tool applied to the workpiece to create an object symmetrical to the axis driven by the spindle.
Slant Bed CNC Lathe
In the machine tool industry, the slant bed CNC lathe is a traditional lathe model and belongs to the conservative category. The user can be appropriately modified to deal with most turning tasks, but a poorly tilted base can avoid chip problems. This type of lathe can be widely used in the industrial field. Therefore, there are no standards or restrictions regarding the design and specifications of the model. With the slant bed nature, the chips caused by the cutting movement are easier to remove. Since the lathe is also called a lathe, it is a machine tool that rotates a workpiece on a rotating shaft to perform various processes, such as cutting, knurling, grinding, drilling, deformation, end face machining, and turning. This machining is performed by using a tool that is applied to the target workpiece, and creates an object with symmetrical profiles, which is driven by the spindle.
High Speed Lathe
In turning tasks, high-speed lathes are multi-task machine production models that can handle a variety of machining tasks with significantly higher spindle speeds. In the EU, the spindle speed in the Asian market should be at least higher than 20,000 RPM, and the speed may be higher. For European models, the speed may even exceed 35,000.
Because of high-speed cutting, a lot of chips are generated during the machining process. If the chips are not removed in time, this is a problem for the lathe. In this type of lathe, the speed of chip removal is also a key issue in frame design.
Conventional and Modern Versions
Although there are many types of turning machine varieties in the industry for the market demands, the conventional lathe works well in certain specific industrial sector just as usual as there are users who need its special mechanism to achieve certain processing demands with manual and slow operations. It is clear that, no matter how technology and science go with the time, conventional mechanical working mechanism will still be needed based on the market.
