Industry 4.0:Futuristic Automated Manufacturing Engineering

When sourcing critical components like Crown Wheels, Tail Pinions, or Bull Gears for high-performance applications, you're investing in precision, consistency, and reliability at scale.

GNA Gears, with a legacy since 1946, stands at the forefront of gear manufacturing, blending traditional expertise with cutting-edge technology to deliver unparalleled quality.

SAP-Powered Smart Manufacturing

At the heart of GNA Gears' operations lies the integration of SAP HANA Cloud Edition (Systems Applications & Products in Data Processing). This enterprise resource planning system ensures:

• Predictive Scheduling: Anticipating production needs to optimize workflow.

• Real-Time Monitoring: Tracking manufacturing processes for immediate insights.

• Zero-Waste Resource Allocation: Maximizing efficiency by minimizing waste.

For OEMs, this translates to consistent quality and timely deliveries, reinforcing trust and reliability.

Robotic Integration in Forging Processes

GNA Gears has revolutionized its forging processes by incorporating robotic automation into hammer forging lines. This advancement offers:

• Consistent Strike Force: Ensuring uniform material deformation.

• Enhanced Material Flow: Achieving optimal grain structure for durability.

• Reduced Human Error: Minimizing inconsistencies in forging operations.

• Improved Worker Safety: Automating hazardous tasks to protect personnel.

This synergy of human expertise and robotic precision guarantees the structural integrity required for demanding applications in the automotive, crane, and tractor industries.

Precision CNC Machining

Post-forging, components undergo meticulous machining using advanced CNC (Computer Numerical Control) equipment, including:

• NC Spline Hobbers

• CNC Gear Hobbers & Shapers

• NC Gear Shavers

• Broaching & Power Skiving Machines

These machines ensure:

• Micron-Level Accuracy: Achieving tight tolerances for optimal performance.

• Consistent Gear Tooth Profiles: Maintaining uniformity across batches.

• High Repeatability: Ensuring each component meets exact specifications.

Such precision is vital for components like Bull Gears and Tail Pinions, which are integral to heavy-duty applications.

Klingelnberg Dry Cutting Technology

GNA Gears employs Klingelnberg Dry Cutting Technology, a state-of-the-art process that offers:

• Faster Cycle Times: Increasing production efficiency.

• Reduced Tool Wear: Extending the lifespan of cutting tools.

• Environmentally Friendly Operations: Eliminating the need for cutting fluids, reducing ecological impact.

This technology ensures that gears meet stringent quality standards while supporting sustainable manufacturing practices.

Gear Grinding: Micron-Level Perfection

At GNA Gears, precision doesn’t stop at cutting—it’s perfected through advanced gear grinding.

Using CNC grinders from Klingelnberg and Reishauer, we achieve:

• DIN 5–6 class accuracy

• Surface roughness below Ra 0.4 μm

• Quiet, high-load gear performance

From bull gears to rotor shafts, gear grinding ensures every tooth runs smoother, lasts longer, and delivers unmatched consistency in demanding applications.

Comprehensive Heat Treatment Facilities

To enhance the mechanical properties of gears, GNA Gears utilizes advanced heat treatment processes, including:

• CNC Induction Hardening Machines

• Sealed Quench Carburizing Furnaces

• Plug Quenching Machines with Rotary Furnaces

• Computer-Controlled Furnaces for Hardening, Tempering, Normalizing, and Annealing

These processes ensure:

• Optimal Hardness: Enhancing wear resistance.

• Improved Toughness: Ensuring durability under stress.

• Dimensional Stability: Maintaining precise dimensions post-treatment.

Such meticulous treatment is crucial for components subjected to high loads and stresses.
