Most lathes are used to work on the exterior and interior surfaces of parts of various shapes, including conical, cylindrical and shaped. The various types of machines also allow you to drill holes and finish ends.
Screw-cutting lathes. They are versatile and designed to perform a large number of operations. Importantly, they also allow for a high level of accuracy. This type of equipment is also required for threading.
The first types of screw-cutting lathes appeared quite a long time ago. Over time, their design improved, they became more and more functional and perfect. The most modern models are equipped with CNC – numerical control. This feature allows you to set the basic parameters of the work, and then the automation will monitor their observance without human intervention.
They are used for mass production of parts from piece workpieces or bar material. Depending on the technological card of a particular part, the tools are arranged in a certain sequence.
Revolver heads can be with vertical or horizontal axis of rotation. Revolvers with a vertical axis of rotation tend to have a higher rigidity. Turning turrets with a horizontal axis can have higher tool change speeds and more positions.
When choosing a model of screw-cutting lathe, it is important to consider its main characteristics:
- The maximum rotational speed of the spindle head, as well as the possibility of its fine-tuning.
- The diameter of the rod to be set in the hole.
- The torque.
- Rated power.
- Number of longitudinal and cross-type feeds.
- The possibility of cutting various types of threads.
All these characteristics depend on the device of the screw-turning lathe and its type. Buy such equipment should only be from proven sellers – official dealers of major companies.
