The page presents pole-end plate machining, a CNC service for generator components, producing high-precision pole-end plates from forged steel using 5-axis machining.

Pole-End Plate Machining for Generators

At Sinitech Industries, we specialize in precision CNC machining of pole-end plates, a critical component used in the construction of electrical generators across the power generation sector.

With several years of focused production experience, we have developed deep technical know-how in pole-end plate machining, supporting manufacturers of large electrical machines with high-quality, reliable components.

Specialized Manufacturing of Generator Pole-End Plates

Pole-end plates play a key structural and functional role in generator assemblies. Their geometry, tolerances, and material properties directly impact the performance and longevity of the generator.

We provide complete machining solutions for pole-end plates, including:

• Machining from forged blanks
• Complex contouring and precision finishing
• Tight tolerance control for assembly-critical interfaces
  
  Our experience covers a wide range of component sizes—from 30 kg up to 500+ kg per unit, ensuring consistent quality regardless of scale.

Materials and Engineering Standards

We primarily machine pole-end plates from high-strength alloy steels commonly used in generator manufacturing, including:

• 42CrMo4
• 34CrMo4
• Equivalent forged materials upon request

Working with forgings allows us to ensure optimal mechanical properties, structural integrity, and durability under demanding operating conditions typical for power generation equipment.

Advanced 5-Axis CNC Machining

All pole-end plates are produced using advanced 5-axis CNC machining centers, enabling:

• High-precision machining of complex geometries
• Accurate execution of functional features
• Repeatable quality across production batches

We are experienced in machining different pole-end plate designs, including:

Dovetail (fir-tree) geometries	Hammer-type configurations

These geometries require precise multi-axis machining strategies, which we have refined through continuous production and process optimization.

Flexible Production Capacity

We support a wide range of production volumes, including:

• Small series (from ~20 units)
• Medium batches (100–200 units)
• Scalable production for larger project requirements

Our manufacturing setup ensures flexibility without compromising precision or delivery reliability.

Proven Experience in the Energy Sector

Our pole-end plate machining services are utilized by companies operating in the hydropower and large electrical equipment manufacturing sectors. We understand the technical requirements, quality expectations, and documentation standards required for such applications.
