The center‑drilling machine specially designed for long shafts is developed for extra‑long shaft components, offering stable support to prevent workpiece sagging and deformation. It can perform center‑hole machining at both ends of long drive shafts, lead screws, and similar workpieces. Manufactured by Juxin Machine Tool Co., Ltd.
Conventional center‑drilling machines can only machine short shaft workpieces; when machining long shafts, the workpiece is prone to sagging and vibration, leading to eccentricity in the center hole and making it difficult to ensure coaxiality. For ultra‑long bar stock, long drive shafts, lead screws, and similar workpieces, it is necessary to select… Centering-hole drilling machine for long shafts The Juxin Machine Tool’s long‑shaft model features an adjustable workpiece support mechanism, addressing the issue of sagging under the weight of long shafts and ensuring stable machining of center holes at both ends of extra‑long shafts.
Challenges in Long-Axis Machining
Workpieces with extremely long shafts have substantial self-weight; after clamping, the midsection tends to sag, leading to vibration during machining. With large end-to-end distances, conventional equipment struggles to achieve proper alignment, often resulting in misalignment of the center holes at both ends and subsequent out-of‑roundness or runout exceeding tolerances during grinding. Standard center‑hole lathes lack auxiliary support structures, making them unsuitable for machining long shafts.
Core configuration of the center-drilling machine specialized for long shafts
- Adjustable intermediate support bracket The support position can be adjusted according to the workpiece’s length and diameter, providing adequate support for the middle section of long shafts, counteracting sagging due to the workpiece’s own weight, reducing machining vibrations, and ensuring alignment accuracy.
- Extended bed frame design The machine bed has been extended to provide ample space for long workpieces, enabling the machining of extra-long shafts of varying lengths.
- Synchronous Double-End Drilling Structure Dual‑spindle synchronous counter‑rotating machining enables one‑time clamping to simultaneously drill and chamfer the center holes at both ends, thereby eliminating the errors introduced by secondary re‑clamping.
- Movable positioning mechanism The positioning mechanism is adjustable along the machine bed, allowing flexible adaptation to workpieces of varying lengths and convenient reconfiguration when switching between part sizes.
Applicable Workpiece Types
Long drive shafts, long lead screws, long optical shafts, long hydraulic cylinder pistons, long bar stock blanks, and long shaft-type components for large-scale equipment.
Key Considerations for Selection
When selecting a center-drilling machine specialized for long shafts, the first step is to confirm… Maximum workpiece length, workpiece diameter, workpiece self-weight The longer the workpiece and the smaller its diameter, the more robust auxiliary support is required. At the same time, determine the machining accuracy requirements to decide whether to select a standard‑precision CNC model or a high‑precision one.

This article examines the applicable scenarios of CNC lathes, dedicated machine tools, and automated machining solutions, based on turning, end-face milling, center-hole drilling, and automation requirements, and outlines the selection criteria for relevant equipment from Juxin Machine Tool.
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.
