Slitter lathe is a special kind of machine tool, ‌ is mainly used for processing slender shaft parts, ‌

 its biggest feature is that the main shaft extension and longitudinal movement in the turning process, ‌ 

and ordinary lathe tool holder extension and longitudinal movement is different. ‌ The design of the slitter lathe 

makes it capable of turning parts with a diameter below 3mm and a length-diameter ratio of ‌ greater than 7, ‌

 is especially suitable for processing complex small parts, ‌ has high precision and stability. ‌ 

This kind of lathe usually has two spindles or multiple spindles, ‌ can be machined respectively or synchronously in 

the main shaft and back shaft, ‌ its more than 5 axis structure can meet the needs of turning, ‌ milling, ‌ drilling and

 other multi-process processing at the same time. ‌ The operation and maintenance of the longitudinal cutting lathe 

is also relatively complex, ‌ need to be correctly adjusted and used, ‌ and pay attention to the maintenance of the 

machine tool, ‌ to ensure the accuracy of the use of the machine tool and extend the service life 12. ‌

In terms of technical parameters and functions, ‌ longitudinal cutting lathe can carry out high-precision machining, ‌ 

for example, Yuanjie CNC Swiss-type automatic longitudinal cutting lathe can carry out deep hole machining 

of hollow bone nails, ‌ the maximum machining depth is up to 110mm, ‌ and has the function of guide sleeve 

automatic air blowing, ‌ prevent cutting fluid from entering the guide sleeve seat. ‌ In addition, ‌ modular power 

tool unit and high rigidity tool rest structure enable the machine to perform heavy cutting on difficult-to-cut

 materials3. ‌

In practical application, ‌ slitter lathe is suitable for machining all kinds of batch parts, ‌ especially in carburetor, ‌

 household appliances, ‌ office equipment, ‌ military, ‌ aviation, ‌ instrument and other industries are widely used. ‌

 it can shorten the product manufacturing process chain, ‌ improve production efficiency, ‌ through one loading
