Electrical Discharge Machining (EDM) Forming Cell

Customer Pain Points

Core Requirements: Focusing on the electrical machining scenario of irregular grooves in aero-engine blades, this solution addresses the core pain points of traditional processing.
Existing Pain Points: In the traditional mode, blade clamping and positioning rely on manual labor, where insufficient precision directly affects machining consistency. Identity recognition and data transmission for both blades and electrodes depend on manual recording, resulting in low efficiency and high error rates, making full-process traceability impossible. There is a lack of an automated mechanism for electrode replacement, dressing, and scrapping, which easily leads to quality defects due to undetected electrode wear. Manual intervention is heavy during inbound/outbound logistics and loading/unloading of blades and electrodes, causing poor process connectivity. Consequently, it fails to meet the high-precision and high-efficiency machining requirements for aero-engine components, creating an urgent need for an integrated intelligent machining cell.

Core configuration of the line body

Core Machining Equipment: Two 6-axis EDM forming machines, precisely matching the electrical machining requirements for irregular grooves in blades, ensuring machining precision and stability.
Automated Execution Unit: One 6-axis articulated robot paired with CHINAF loading/unloading carts realizes automatic loading/unloading and transfer of blades and electrodes; supplemented by a high-precision pallet system to ensure accurate positioning.
Intelligent Storage Unit: CHINAF workpiece library and electrode library realize automatic inbound/outbound of blades and electrodes, reducing manual operations and achieving precise material control.
Inspection and Auxiliary Systems: CHINAF loading/unloading stations (integrating workpiece and electrode prediction systems) combined with the RFID automatic identification system realize identity recognition and automatic data transmission; equipped with an electrode dressing system, CHINAF cleaning system, and safety protection system to ensure machining quality and production line safety.
Intelligent Control Hub: The CHINAF PCS control system realizes unified control over the cell, constructing an integrated digital management system.

Core Value

Full-Process Automation, Enhancing Production Efficiency: Through the synergy of the 6-axis articulated robot and the CHINAF PCS control system, unmanned control of the machining process is realized, covering automatic loading/unloading, transfer, machining, and inbound/outbound of blades and electrodes. Manual intervention is reduced by over 80%, process connection efficiency is increased by 50%, and overall production efficiency is significantly boosted.
High-Precision Control, Ensuring Machining Quality: The 5-axis CNC loading/unloading inspection station integrates touch probing and vision technology, controlling workpiece pose adjustment precision within ±0.005mm. Electrode wear is detected online in real-time, and repair parameters are transmitted synchronously. With an electrode repair precision of 99.9%, the qualification rate for machining irregular grooves in blades is increased to over 99.8%, meeting the high-precision requirements of aero-engine components.
Significant Cost Optimization, Breaking Technical Bottlenecks: By innovatively adopting graphite electrodes and resolving their processing challenges, machining efficiency is increased by more than 3 times compared to traditional copper-tungsten electrodes. Electrode procurement and usage costs are reduced to approximately 25% of those for copper-tungsten electrodes, saving about 30,000 RMB per batch and achieving an annual cost reduction of over 20% with long-term use.
Digital Management, Achieving Full-Process Traceability: Integrating the CHINAF PCS control system with the RFID system realizes automatic collection, transmission, and management of identity information and machining data for blades and electrodes. Automatic compensation response time for machining parameters is ≤1 second, with a traceability rate of 100%, providing precise data support for process optimization and equipment maintenance, assisting the client in realizing lean management.
