EDM

Avec plus de 1,100 Electrical Discharge Machining (EDM) les machines, Meyer est le plus grand atelier d'usinage EDM au monde. EDM, also referred to as spark machining, est le processus de production d'une forme souhaitée en un produit métallique en utilisant une série rapide d'étincelles. The working spark is generated by creating a strong imbalance of ionization potential between the product and the tool by charging one with positive ions and the other with negative. As the tool (electrode) and the work piece reach a close proximity to one another, the spark bridges the gap between the two and erodes away both the product and the electrode.

Multi Axis Fast-Hole EDM

Meyer est le plus grand utilisateur mondial d'usinage par électroérosion à trous rapides (EDM).
  • Over 800 CNC Small Hole Drillers
  • Over 400 Conventional Sinker EDM
  • Average of 1.7 million cooling holes per day for the gas turbine engine industry
  • Proprietary fast-hole EDM process allows us to maintain a hole diameter of ±.0005″ and internal flow measurements within ±3% of nominal under normal conditions
  • Capability of machining down to .010″ at a depth to diameter ratio 100:1
Our patented Encore shaping process allows for the manufacturing of complex 3D-shaped diffusers with the hole in a single process sequence.
  • Eliminates mismatched shape tool/hole conditions common to the competition’s two-step process
  • Provides better control over internal mass airflow and the shape of the diffuser characteristic
In order to ensure that all customer requirements are consistently met, Meyer conçoit et commercialise des équipements d'inspection automatisés spécifiques à la nature du processus de refroidissement des trous.
  • Meyer conçu Cinq axes Vision Systems pour mesurer l'emplacement de chaque trou de refroidissement indépendamment, providing the machinist with critical positioning feedback
  • The Networked Airflow Test Stand measures the internal mass flow rate through each cooling circuit to ensure all areas of the product receive proper cooling
  • Using back lighting, pressurized water and infra-red radiometer based gauging systems, Meyer est en mesure de vérifier que chaque trou du produit est complètement traversant et exempt de corps étrangers

Conventional Ram / Sinker EDM

Electrical Discharge Machining (EDM) allows intricate shapes and contours to be machined into all types of metal products.
  • Nearly 200 Ram / Sinker EDM machines through a combination of manual and programmable CNC machine centers
  • Precision down to ±.0005″ inches
  • Surface finishes down to 63 Ra µin
Notre équipe de conception interne, associée à notre salle d'outillage d'électrodes, offre à Meyer la flexibilité nécessaire pour générer des électrodes nouvelles et repensées chez les clients.’ request.
  • Proprietary power supply technology
  • Unprecedented control over the performance of the cut
  • CMM and non-contact vision inspection systems

Wire EDM

Le procédé Wire EDM de Meyer est une méthode très précise de découpe de formes complexes à travers des superalliages, using a traveling wire electrode between .004″ et .012″ in diameter.
  • Over 35 Wire EDM machines for use in production
  • Quick release tooling
  • Capable of machining within tolerances as tight as ±.0002″
  • Perform 30° or greater tapered cuts
