The structure of the double-sided lathe spindle mainly includes the following parts :
spindle box : The spindle box is an important part of the lathe, responsible for driving the spindle rotation. It usually contains a motor, transmission and lubrication system to ensure smooth and efficient operation of the spindle .
main shaft : the main shaft is the core part of the lathe, responsible for driving the workpiece rotation. The main shaft is usually designed as a hollow step shaft, the inner hole is used to pass through the bar material, the front and back cone holes are used to install the sleeve and the mandrel, and the workpiece is rotated by friction .
cutter head device : cutter head device is installed on the main shaft, used to install the tool for cutting. The cutter head device of modern lathes usually uses a power cutter tower, which can realize multi-process processing and improve processing efficiency and accuracy .
feed system : The feed system is responsible for controlling the movement of the spindle and cutter head to realize the feed movement of the workpiece. The advanced feed system is controlled by AC servo motor to ensure positioning accuracy and dynamic performance .
guide : The lathe's guide system ensures steady movement of the spindle and cutter head in both vertical and horizontal directions. Modern lathes mostly use high-precision linear rolling guide rails to improve the stability and accuracy of machine tools .
Working principle of double sided lathe spindle :
The spindle of the double-sided lathe is driven by the motor to rotate and drive the workpiece to be processed. The cutter head device is installed on the spindle, and different tools are replaced according to the machining needs. The feed system controls the movement of the spindle and cutter head to realize the feed and cutting of the workpiece. The guide system ensures the stability and accuracy of the spindle and cutter head during machining. Through the cooperative work of these parts, double-sided lathes can achieve efficient and high-precision machining
