Adjusting the positioning of the drill bit and the workpiece: Ensure that the cutting edge of the drill bit is symmetrical and that the end face of the workpiece is perpendicular to the centerline of the drill bit. If the drilling position is found to be offset or tilted, it can be resolved by sharpening the side cutting edge, replacing the drill bit, or reducing the feed rate.
The slender shaft, due to its large length-to-diameter ratio and poor rigidity, is prone to bending deformation and vibration during the turning process, making it difficult to process.
To effectively process slender shafts, we often need to take various measures to improve processing accuracy and stability. For example, adjusting the alignment of the spindle and tailstock centers to ensure they are parallel to the main guide rails of the lathe, with a tolerance of less than 0.02mm. Additionally, processing slender shafts often involves reversing operations and multiple clamping, which not only affects accuracy but also consumes time and effort.
In response to the above issues, our company has successfully developed a vertical lathe capable of processing slender shafts in one go, which is a dual-spindle vertical lathe with dual systems and dual stations after two years of research and development.
It can process slender shafts with a length-to-diameter ratio of 33 times in one go!!!
The processing technology for slender shafts of this dual vertical lathe is currently applying for an international patent, representing a new technology globally.
The main features of this dual vertical lathe for slender shafts are:
1. It can complete the processing of slender shafts with a length-to-diameter ratio of 33 times in one go, without the need for reversing or secondary clamping.
2. Inward clamping chuck reduces vibration and ensures accuracy.
3. Segmented processing ensures accuracy.
4. Retains the advantages of dual-spindle vertical lathes, such as processing two identical or different slender shaft parts simultaneously, reducing labor, lowering costs, and improving efficiency.
5. Retains the advantages of vertical lathes, occupying less floor space, with one machine serving the purpose of two.
This concludes the introduction of the new model - dual spindle vertical lathe for slender shafts by Juxin Machine Tool. We hope it can assist you in processing slender shaft parts. If you have any questions or suggestions, feel free to leave a comment below. Let's learn and progress together!

How should machining equipment be selected for batch production of shaft-type components? This article examines the applicable scenarios of conventional CNC lathes, specialized machine tools, twin‑station twin‑spindle vertical CNC lathes, and center‑drive twin‑head CNC lathes, focusing on processes such as end-face machining, center‑hole drilling, external cylindrical turning, threading, and dual‑end machining, thereby helping enterprises to design efficient batch‑production strategies.
What should you do if shaft‑type machining equipment takes up too much floor space?
Excessive floor space requirements, insufficient workshop capacity, and the inability to scale production are common pain points for most machining enterprises. The Juxin dual‑station, dual‑spindle CNC vertical lathe features an ultra‑compact design, occupying only 5 m² per unit—replacing two conventional lathes and reducing space needs by 70%—thus providing an ideal solution to the challenge of limited shop‑floor space in shaft‑machining operations.
How can efficiency be improved in the mass production of shaft components?
The key to boosting efficiency in high-volume shaft machining lies not in shortening cycle times or repeatedly reorienting and aligning workpieces, but in streamlining processes, simplifying equipment, and reducing the workload on operators. The Juxin dual‑station, dual‑spindle CNC vertical lathe can replace two machines with a single unit, enabling simultaneous machining at both stations, thereby significantly cutting handling, labor, and facility‑space costs. Moreover, substituting turning for grinding further enhances process efficiency.
What turning equipment is used for batch machining of shaft-type parts?
For the mass production of shaft-type components, the Juxin dual‑station, dual‑spindle CNC vertical lathe is the preferred choice. Unlike conventional single‑station vertical lathes or the cumbersome arrangement of multiple standard lathes, its two independent machining units can simultaneously perform both forward and reverse operations on a workpiece, occupying less floor space, reducing labor costs, and offering superior rigidity—enabling hard turning of quenched parts. It is an efficient, purpose-built machine for high‑volume shaft‑part manufacturing.
What equipment is used for the mass production of shaft-type parts?
For the mass production of shaft-type parts, equipment selection should not focus solely on the machining speed of a single machine tool; it must also take into account the total number of machines, floor space requirements, staffing levels, workpiece handling, and the organization of forward and reverse operations. For shaft components that require both forward and reverse machining steps, using two conventional lathes to perform these operations separately would not only necessitate two machines but also create challenges related to workpiece transfer and personnel allocation. A dual‑station, dual‑spindle CNC vertical lathe integrates two independent machining units—each equipped with its own spindle, turret, and CNC system—into a single machine, enabling separate processing of different operations on the same workpiece according to the manufacturing process. In mass production of shaft-type parts, this approach allows for a re‑optimized production layout across three key dimensions: equipment count, available shop floor space, and workforce configuration.
Can a machine tool simultaneously machine both ends of shaft-type parts?
Can a single machine tool simultaneously turn both ends of a shaft‑type part? The Juxin dual‑station, dual‑spindle CNC vertical lathe replaces two conventional lathes in one unit, streamlining the machining process, reducing floor space by 70%, cutting handling time, and lowering labor costs by 50%, making it ideal for high‑volume, efficient production of shaft‑type components.
How should the two ends of shaft-type parts be machined?
How are the ends of shaft-type parts machined? Compared with the traditional lathe’s two‑step clamping process, the Juxin JXLC40A dual‑station, dual‑spindle CNC vertical lathe features two independent machining units that perform simultaneous end‑to‑end machining in a single setup, ensuring stable coaxiality. With a footprint of just 5 m², it saves space and reduces labor costs, while its high rigidity supports hard turning as a substitute for grinding, making it ideal for batch processing of shafts and disc‑shaped components.
What machine tools are typically used to machine shaft-type parts?
This article addresses the types of machine tools commonly used for machining shaft components and the specific machining processes involved. By comparing the characteristics of various lathes, it introduces the Juxin dual‑station, dual‑spindle CNC vertical lathe: a single unit equipped with two independent machining stations, effectively replacing two conventional lathes; occupying only 5 m², it saves 70% of floor space compared to two traditional lathes, reduces workpiece handling distances, and allows one operator to manage three machines, cutting labor requirements by 50%. Its robust frame supports hard‑turning of quenched parts, enabling turning to replace grinding.
