I. Comparison of Mainstream Machine Tools for Shaft-Type Parts (A Clear and Informative Overview of Their Pros and Cons)

The shaft-type workpieces and production scenarios that different machine tools are suited to vary significantly; only precise equipment selection can balance quality, efficiency, and cost.

General-purpose horizontal lathe : This method is suitable only for single-piece and small-batch rough machining, with low automation and high reliance on manual labor. It cannot meet the demands of standardized mass production, suffers from poor precision and consistency, and is no longer appropriate for large-scale machining of shaft-type parts.

Conventional CNC lathe / Single-station CNC lathe : Conventional shaft‑machining equipment on the market features a single processing unit per machine, requiring separate machines and multiple setups to complete both the front‑side and back‑side operations of a workpiece. To perform both sides of the machining process, two machines must be purchased, which not only occupy a large footprint and demand significant labor input but also involve time‑consuming manual transfer between machines, keeping overall production costs persistently high.

CNC grinding machine : Used solely for finish‑machining and polishing of parts, it is a post‑process auxiliary operation that cannot independently complete the full turning and shaping of shaft‑type components. It features a single‑step machining process and requires a high capital investment in equipment.

Juxin Double-Station, Double-Spindle CNC Vertical Lathe : Specifically customized for the mass production of shaft and disc‑type parts, with a key distinction from conventional lathes: A single machine is equipped with two independent machining units. A single machine can replace two conventional CNC lathes, simultaneously performing both forward and reverse‑side machining of the workpiece, while also delivering exceptional rigidity and hard‑turning capabilities. It is currently the preferred solution for efficient, low‑cost machining of shaft‑type and disc‑type components.

II. How are shaft-type parts machined? An overview of standard machining processes.

The core requirements for machining shaft-type components are to achieve complete shaping of the blank’s outer diameter, end faces, steps, and chamfers, while ensuring dimensional accuracy and batch-to-batch consistency; for certain high-hardness workpieces, precision finishing must also be performed after quenching. Relying on… Juxin Double-Station, Double-Spindle CNC Vertical Lathe , enabling standardized, integrated machining of shaft-type components; the complete process flow is as follows:

1. At the loading station, the workpiece blank is clamped, and leveraging the equipment’s dual independent machining unit configuration, the forward and reverse process paths are pre-planned.

2. Dual‑station simultaneous operation: while one station completes rough and finish turning on the workpiece’s front side, the other station concurrently performs finish machining on the back side, enabling a single machine to accomplish the workload of two conventional lathes.

3. For high-hardness shaft components after quenching, leveraging the machine tool’s highly rigid structure to perform direct hard turning, thereby achieving… Using a car as a substitute for grinding , eliminating the need for secondary machining on the grinding machine;

4. After processing is complete, workstations alternate in unloading parts, seamlessly integrating with the automated assembly line to achieve batch‑scale, standardized production.

Compared with conventional machining processes, this workflow eliminates the need to transfer workpieces between machines and to assign operators to multiple pieces of equipment, achieving a high degree of process integration and making it ideally suited for mass production of shaft‑type and disc‑type components.

III. Core Exclusive Advantages of the Juxin Dual-Station, Dual-Spindle CNC Vertical Lathe (Precision Process Selling Points)

Unlike conventional vertical lathes and traditional CNC lathes on the market, the core advantage of Juxin’s dual‑station, dual‑spindle CNC vertical lathe lies not merely in reducing the number of setups or eliminating the need to reorient and re‑align workpieces, but rather… Intensive production capacity with a single machine featuring two independent machining units, combined with high-rigidity hard-turning performance. , reducing costs and boosting efficiency across four key dimensions: site, equipment, labor, and processes:

1. One device replaces two, cutting equipment investment by half.

In traditional manufacturing, machining shaft-type components requires two separate operations—one for each end—necessitating the purchase of two independent CNC lathes to perform these processes in tandem. In contrast, the Juxin dual‑station, dual‑spindle CNC vertical lathe… Each individual machine is equipped with two independent machining units. It enables simultaneous machining of both the front and back sides of a workpiece on the same machine tool, with a single unit replacing two conventional lathes and significantly reducing enterprises’ equipment procurement costs.

2. Maximizes space savings, increasing space utilization by 70%

Traditionally, two CNC lathes require a large amount of workshop space, whereas the Juxin dual‑station, dual‑spindle CNC vertical lathe features a compact overall structure. A single unit occupies only 5 square meters. Compared with two conventional lathes, this solution can directly reduce the required production floor space by more than 70%, significantly optimizing workshop layout—making it particularly well-suited for small and medium-sized machining shops and mass-production facilities with limited space.

3. Shorten material handling distances, saving transfer time and labor.

In the traditional two‑machine machining process, workpieces must be repeatedly transferred and handled between two lathes, which is time‑consuming, labor‑intensive, and prone to impact‑induced damage. By contrast, Juxin’s dual‑station vertical lathe features an integrated dual‑station layout: workpieces circulate solely within the machine’s internal stations, significantly reducing handling distances and eliminating cross‑machine transfer steps. This effectively cuts material‑handling time and boosts overall production throughput.

4. Labor efficiency has doubled, and labor costs have been reduced by 50%.

Traditionally, six standard CNC lathes would require six operators to be on duty at all times; in contrast, the Juxin dual‑station, dual‑spindle CNC vertical lathe boasts highly adaptable automation. One worker can simultaneously manage three pieces of equipment. Under the same production capacity, labor requirements are cut by 50%, with reduced operator error margins and faster production response times, effectively addressing the challenges of high labor costs and recruitment difficulties in mass production.

5. High-rigidity machine body, supporting hard turning and turning‑as‑grinding.

This is the core differentiating highlight of Juxin equipment! The machine body features a reinforced, rigid design that delivers exceptional structural stability, enabling it not only to process standard blank shaft components but also to directly handle… High-hardness shaft and disc workpieces after quenching Perform finish turning. In conventional processes, after quenching, a grinding machine is required for finishing, resulting in cumbersome procedures and high equipment investment; however, this equipment can achieve… Using a car as a substitute for grinding , thereby eliminating the grinding step, streamlining the production process, enhancing machining accuracy, and significantly reducing subsequent processing costs.

IV. Case Study on In‑Plant Machining: A Real‑World Example of Cost Reduction and Efficiency Gains in Mass Production of Shaft Components

A certain construction machinery components manufacturer specializes in mass-producing parts such as motor shafts, transmission stub shafts, and gear shafts. Its existing production setup includes six conventional CNC lathes, but it faces challenges including cramped workshop space, high labor costs, cumbersome heat‑treatment machining processes, and constrained production capacity, making an urgent optimization of the production line essential.

Existing production pain points : Six lathes occupy a large footprint and require six operators on duty, resulting in high labor costs; shaft components undergo separate forward and reverse machining processes, with time‑consuming material handling; after quenching, the shafts must undergo secondary grinding, leading to numerous operations and a lengthy production cycle.

Upgrade Plan : Procure three Juxin double‑station, dual‑spindle CNC vertical lathes to fully replace the existing six conventional lathes.

Actual machining results ：
