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.
In the mass production of shaft-type parts, many factories face a common challenge: both ends of the workpiece require turning of the outer diameter, end faces, and grooves. Traditional machining methods necessitate repeatedly transferring the workpiece between two lathes, with secondary setups and alignment consuming significant time, introducing substantial positioning errors, occupying considerable floor space, and keeping labor costs high. As a result, numerous manufacturing enterprises have been seeking stable, high‑efficiency process solutions for machining both ends of shafts.
What are the traditional methods for machining both ends of shaft-type components? An analysis of their advantages and disadvantages.
- Two standard CNC lathes perform machining in separate operations. The first lathe clamps the workpiece and machines one end; once completed, it is removed, transferred to the second lathe, re‑clamped, and aligned before machining the other end. Advantages: low equipment entry barrier and straightforward machine selection. Disadvantages: secondary clamping introduces positioning errors; long travel distances for workpiece handling require multiple operators; the two machines occupy a large footprint; labor costs are high, limiting overall efficiency in batch production.
- Secondary clamping and flipping machining on a single lathe The same machine tool is used to unload the workpiece, manually reorient it, and re‑clamp it before machining the other end. Advantages: Only one machine tool is required, resulting in low initial equipment investment. Disadvantages: Reorientation and alignment are time‑consuming; human error can affect coaxiality; it is unsuitable for high‑volume, stable production; and it imposes a high level of physical labor on operators.
Many people mistakenly believe that the core challenge in machining both ends of shaft-type parts is simply to reduce workpiece clamping and flipping. In reality, addressing only the issue of re‑positioning and alignment can be accomplished by adding a standard lathe; however, this approach fails to tackle the deeper problems related to shop‑floor space, labor costs, and equipment utilization.
A new high-efficiency machining process for shaft-type parts: a dual-station, dual-spindle CNC vertical lathe.
To meet the demand for simultaneous machining of both ends of shaft-type components, Juxin Machine Tool’s dual‑station, dual‑spindle CNC vertical lathe is equipped with… Two independent processing units A single machine can perform simultaneous machining of both ends of a workpiece, making it the preferred solution for turning shaft-type components.
Its core feature lies not only in simplifying workpiece clamping, but also in… One machine delivers the machining capabilities of two conventional lathes. 。
- Significant space savings : Two conventional lathes occupy a large footprint, whereas the Juxin dual‑station, dual‑spindle CNC vertical lathe requires only about 5 m². Compared with two traditional lathes, it reduces space requirements by 70%, making it an ideal solution for manufacturing facilities with limited floor space.
- Shorten material handling distances : The workpiece is machined at both ends on the same machine, resulting in short material handling distances and reduced transfer time.
- Workforce Optimization : The equipment boasts a high degree of automation, enabling a single operator to manage three twin‑station vertical lathes—equivalent to the output of six conventional lathes—while reducing labor requirements by 50% and mitigating production instability caused by recruitment challenges and employee turnover.
- A high-rigidity machine body supports hard turning. The machine tool boasts ample rigidity, enabling direct hard turning of quenched workpieces, thereby replacing grinding and reducing subsequent grinding operations, thus shortening the complete manufacturing process for shaft-type components.
Additional note: In addition to shaft-type parts, this equipment also offers significant space‑saving benefits in the machining of disc‑type components.
Process Application Cases
A mechanical components processing plant in Zhejiang mass‑produces various short‑shaft parts, with each component requiring simultaneous machining of both end faces and the outer diameters at both ends. Previously, two CNC lathes were used to handle the operation in separate stages. However, due to limited workshop space, two operators were needed for the two machines, resulting in frequent workpiece transfers and occasional out‑of‑tolerance coaxiality after secondary setups.
After the enterprise introduced the Juxin dual‑station, dual‑spindle CNC vertical lathe:
- One piece of equipment handles the machining tasks previously performed by two lathes, occupying only 5 m² and freeing up substantial workshop space.
- The workpiece’s forward and reverse sequences are completed simultaneously on two independent machining units of the same machine, eliminating the need for transfer between machines.
- One operator manages three pieces of equipment, reducing labor costs.
- For quenched shaft components, direct hard turning can replace grinding, simplifying the process and improving the dimensional stability of the finished parts.
