CNC Shot Peening: Technology & Applications

At the core of SFECIndia’s offerings is the CNC Shot Peening Machine for Gears and Shafts. This precision‑engineered system uses controlled robotic or turbine‑blasting techniques to impart compressive residual stresses on component surfaces..

Key advantages include:

• Precision and repeatability: CNC control ensures consistent peening depth, coverage, and intensity.
  
  

• Fatigue performance improvement: Ideal for components like gears, shafts, and axles where service life is critical.
  
  

• Embedded dust collection systems: Automatic dust/fines extraction for cleaner, safer operation IPF OnlineIPF Online+3sfecindia.net+3sfecindia.net+3.
  
  

Range of Shot Peening Equipment

SFECIndia’s shot peening portfolio includes:

• Air‑Operated (Nozzle‑Operated) Indexing Table Machines – featuring multiple job‑stations (2, 4, 6, etc.) that automate loading/peening/unloading in a continuous sequence. These are commonly used for gears, shafts, and other medium‑volume components. The process is enhanced by indexing tables and nozzle arrays with real‑time dust control sfecindia.net+2sfecindia.net+2.
  
  

• Airless (Turbine‑Operated) Machines – utilizing extremely high velocity centrifugal turbine wheels, suitable for high‑throughput or heavy‑duty applications where energy efficiency and consistency are required sfecindia.net+2sfecindia.net+2.
  
  

• Robotic Shot Peening Systems – designed for high‑volume, complex automobile and aerospace components. Recent innovations include dual‑6‑axis robotic peening machines, equipped with part‑recognition capabilities, automatic recipe selection, Magna valves, Sweco shot classifiers, and Safe Move software to control and verify peening intensity and coverage. These systems hit cycle times of ~60–80 seconds with uptime exceeding 99% IPF Online.
  
  

Industry Verticals & Typical Use Cases

SFECIndia serves multiple sectors:

• Automotive: Gears, shafts, axle beams, springs. The robotic shot peening machine is optimized for axle beams of four‑wheelers, reducing idle time and increasing fatigue life significantly IPF Online.
  
  

• Aerospace: Precision parts requiring strict residual stress control, such as aerospace-grade gears and shafts.
  
  

• Oil & Gas / Heavy Engineering: Components exposed to cyclic loading and harsh environments.
  
  

• Spring Manufacturing: Dedicated shot peening rigs for coil springs and leaf springs to improve life and performance sfecindia.net.
  
  

Manufacturing Excellence & Customer Support

SFECIndia’s manufacturing prowess stems from in‑house capabilities including CNC plasma cutting, automatic radial drilling, sheet bending, and heavy‑duty welding. The company employs modern automation and fabrication lines to produce robust and precise equipment Datanyze.

Service and support are integral: SFECIndia maintains stock of spare parts, has a trained technician network, and offers testing, installation, and maintenance services nationwide and abroad sfecindia.net.

Why SFECIndia Stands Out

• Decades of experience: Almost five decades of specialization in peening and blasting technology.
  
  

• Comprehensive range: From manual table‑top systems to advanced dual‑robot lines.
  
  

• Technology-driven: Advanced CNC control, robotic automation, automated recipe-based operations, compliance with European safety and peening standards 

• Quality and compliance: ISO & CE certifications, environmentally conscious design, national and global presence.
  
  

• Customer centricity: Customization for specific jobs, onsite training, and responsive after‑sales service.
  
  

Choosing the Right CNC Shot Peening Solution

When selecting a manufacturer in India:

• Assess your volume: Lower volumes may use indexing table systems; large volumes benefit from robotic peening.
  
  

• Material and component type: Components with complex geometries may need robotic or spindle‑based systems to ensure uniform coverage.
  
  

• Fatigue life requirements: High‑stress environments require tightly controlled peening intensity and validation systems.
  
  

• Automation and integration: Consider machine capabilities for recipe recall, part identification, data logging, and compliance records.
  
  

SFECIndia designs both air‑blasted and wheel‑blasted CNC peening systems, tailored to customer requirements and industry usage.

Real‑World Example: Automotive Axle Beam Application

SFECIndia’s dual‑robot shot peening machine for axle beams exemplifies innovation and process optimization. It features twin jigs on a trolley system: while one jig is peened by coordinated dual robots, the other is loaded/unloaded. Real‑time shot size control, part recognition for program selection, and cycle times under 80 seconds make it ideal for Tier‑1 automotive suppliers seeking high throughput and reliability sfecindia.netIPF Online.

Future Directions & Innovation Pipeline

SFECIndia stays abreast of new trends:

• Smart systems: Cameras and sensors that validate part presence and peening coverage.
  
  

• Higher automation: Robotic systems with near‑zero idle time, ensuring continuous operation.
  
  

• Process analytics: Integration of intensity and coverage tracking to provide quality assurance.
  
  

• Global standards compliance: Machines built to meet international safety, peening, and emissions standards.
  
  

Conclusion

In an industry where fatigue resistance, consistent peening performance, and automation are critical, SFECIndia delivers trusted solutions. From gear and shaft CNC peening units to robotic systems for automotive mass production, their technology enables clients to extend component life, improve quality control, and streamline operations.
