In the field of mechanical manufacturing, the lathe is hailed as the "mother machine of industry". Its core function is to perform cutting operations through the rotation of the workpiece and the movement of the tool. This unique processing method makes it irreplaceable in the production of various rotationally symmetric standard parts. So, what common standard parts can a lathe actually manufacture?
Connection and Fastening Parts
Connection and fastening parts are the most typical "products" of lathes. From the ubiquitous screws, bolts, and nuts to the foundation anchor bolts of equipment, their threaded parts almost all rely on lathes for turning to ensure precise pitch and thread profile. In addition, pins, bushings, etc., used for positioning or connection, also depend on lathes to process precise outer circles and inner holes.
Transmission and Support Parts
Transmission and support parts are also inseparable from lathes. The transmission shaft is a model of lathe processing. Whether it is a smooth shaft, a stepped shaft, or a shaft with threads, its precise diameter and coaxiality need to be guaranteed by a lathe. The shaft sleeve, a key component in sliding bearings, also requires turning to achieve strict dimensional tolerances and surface finish for its inner and outer cylindrical surfaces. In addition, the finishing of the outer circle, end face, and inner hole of disc and sleeve parts such as pulleys and coupling flanges is also a specialty of lathes.
Other Functional Standard Parts
Besides these, lathes can also easily manufacture many other functional standard parts. For example, threaded joints for pipe connections, handles of various measuring tools, and some specifications of balls and cages in ball bearings. With special process equipment, lathes can even process ball screws with extremely high precision requirements.
In summary, from the tiniest screw to the several-meter-long transmission shaft, the lathe, with its excellent processing capabilities, has laid the foundation for the standardization and mass production of modern industry. These standard parts born from lathes are like the "cells" in the industrial system, forming the basis for the stable operation of large mechanical equipment.
