See how SIGER Data's adaptive machining system optimizes multi-axis relay cycle time, helping to reduce costs and increase efficiency!

Company News       Date：2026/04/27

In a precision manufacturing workshop, a Swiss-type CNC lathe is mass-producing precision threaded shaft parts. Operators have long faced a dilemma: ensuring the dimensional accuracy of the slender shaft structure and the surface quality of the threads while simultaneously dealing with ever-increasing production capacity.

Speeding up? Thread cutting is extremely sensitive to feed consistency; even a slightly faster feed will trigger vibrations, leading to abnormal thread profiles or surface scratches.

Slowing down? The spindle-back shaft relay process already involves cycle time losses, and when combined with a conservative feed, the time per piece remains consistently high.

This "wanting to go fast but not daring to go fast" impasse is particularly pronounced when machining slender threaded shafts using a Swiss-type lathe: the cycle time interruption during spindle-back shaft relay, the extreme stability requirements of continuous thread cutting, and the conservative parameters under multi-process integration… each of these factors squeezes the equipment's actual capacity.

How can a Swiss-type lathe "run faster and move more steadily" while ensuring thread accuracy? SIGER Data's Adaptive Machining System uses an intelligent closed loop of "real-time perception + AI decision-making + smooth execution" to equip the Swiss-type lathe with eyes that can perceive the load and a brain that can dynamically adjust the speed, enabling threaded shaft machining to truly achieve "stability while seeking speed".

1. Three Major Pain Points: Common Challenges in Machining Slim Threaded Shafts by Swiss-type Lathes

In machining slender shafts and other precision threaded shafts, the shortcomings of traditional fixed feed strategies are glaringly apparent:

❌ Parameter Lock-in, Limited Capacity: To avoid the risks of thread cutting and chatter on slender shafts, feed parameters are generally set conservatively. The equipment is constantly confined to its "safe zone," preventing the true efficiency of the spindle and back spindle from being realized, resulting in persistently high single-piece times.

❌ Discontinuous Loading, Difficult Quality Control: During spindle-back spindle switching and coordination, discontinuous loads and mismatched cycle times easily produce vibration marks or tool marks on the mating surfaces, directly affecting thread accuracy and geometric tolerances. Experienced operators can only rely on manual speed reduction to "smooth the transition", further lengthening the cycle time.

❌ EMulti-Process Integration, Difficulty in Speeding Up: With external turning, boring, threading, and complex processes running in combination, manual parameter adjustment struggles to achieve optimal feed for each process segment. The overall production cycle is hampered by its weakest link; any conservative parameters in any segment will become the "weakest link" in production capacity.

Behind this lies an inevitable choice: to "teach the automatic loom to dynamically adapt to multiple axes".

2. Intelligent Breakthrough: The AMS Adaptive Machining System Equips Swiss-type Lathes with an "AI Brain"

The SIGER Data Adaptive Machining System is a complete closed loop consisting of "real-time perception → AI decision-making → smooth execution". It's not simply about increasing or decreasing overall speed, but rather about achieving millisecond-level dynamic feed optimization tailored to the characteristics of Swiss-type lathes: "continuous feed + dual-spindle relay + multi-process integration".

✅ High-Sensitivity Perception Network

The system collects power load signals from the spindle and back spindle in real time, essentially equipping each spindle with "nerve endings" .Whether it's heavy-load cutting during rough turning of the outer diameter, minute fluctuations during thread finishing, or even sudden load changes during relay, everything can be captured in milliseconds.

✅ AI Dynamic Decision-Making Model

The system's built-in AI algorithm performs millisecond-level calculations based on the deviation between a preset target load threshold and the real-time load: automatically increasing the feed limit to unleash potential in low-load ranges; and intelligently reducing speed when the load approaches the threshold to avoid overload and vibration risks.

✅ Smooth Execution and Cross-Axis Collaboration

Through precise algorithms to filter signal noise and suppress speed overshoot, stepless continuous adjustment of the feed rate is achieved. Simultaneously, for the spindle-back axis relay process, the system automatically matches the dual-axis load curves, forming an optimized mode of "continuous feed adaptive + multi-axis collaborative matching",completely eliminating cycle breakpoints and surface abrupt changes during relay.

3. Real-world Testing: 21.3% Efficiency Improvement, Truly "Stable Yet Fast"

In a real-world scenario of machining precision threaded shafts on a Swiss-type CNC lathe, SIGER Data's Adaptive Machining System delivered impressive results:

Original Single-Piece Machining Cycle Time: 122 seconds

Optimized Single-Piece Machining Cycle Time: 96 seconds

Overall Machining Efficiency Improvement: 21.3% (Reduced by 26 seconds)

More importantly, this improvement did not come at the expense of quality—in key areas such as thread cutting, spindle back-shaft relay, and multi-process transitions, the AMS system ensured extreme stability in the cutting process by suppressing overshoot, filtering noise, and smoothly adjusting feed, completely eliminating vibration marks and tool marks, ensuring that both the precision and surface quality of the threaded shaft met the standards.

4. Beyond Data: The Panoramic Value for Customers

The value of SIGER Data's Adaptive Machining System goes far beyond simply reducing the cycle time of a single part. It builds a core competitive advantage for sustainable evolution for Swiss-type lathe manufacturers:

4.1 Unleashing Capacity: Breaking free from the constraints of conservative parameters, a 21.3% reduction in cycle time means directly releasing more than one-fifth of the production capacity without adding equipment. With the same equipment and personnel, nearly a hundred more threaded shafts can be produced daily.

4.2 Quality Assurance: Intelligent and smooth feed adjustment and dual-axis coordinated matching effectively suppress vibration during thread cutting and relay processes. Say goodbye to vibration marks and tool marks, meaning higher yield rates, lower rework costs, and more reliable delivery capabilities.

4.3 Intelligent Accumulation: The system continuously learns from data on similar materials and thread processing conditions, transforming the experience of experienced operators adjusting speed "by feel" into a quantifiable, learnable, and reusable optimal parameter model. The introduction cycle for new workpieces, new processes, and new employees has been significantly shortened, making standardized production possible.

4.4 Digital Foundation: The continuously accumulating load-feed data flow builds valuable core data assets for deeper process optimization, tool life prediction, and even digital twins.
