PECM – Precision at the Atomic Level

At Scerox, we utilize the PECM process from Pemtech for high-precision electrochemical metal machining. PECM stands for Pulsed Electrochemical Machining, a cutting-edge technology used in industrial manufacturing, particularly for highly precise machining processes of electrically conductive materials such as metals.

The PECM process is based on electrochemical methods where an electrolyte and electrical current are used to remove material with exceptional precision. Unlike traditional mechanical machining methods, which physically remove material using tools, PECM relies on chemical reactions to dissolve material at the atomic level.

Advantages of PECM:

High Precision: Achieves exceptional accuracy without causing mechanical stress or deformation.
Ideal for Tight Tolerances: Perfect for components that require the highest dimensional precision.
Complex Geometries: Capable of machining intricate shapes and fine details that are challenging with conventional methods.
Machining Difficult Materials: Suitable for materials that are traditionally difficult to process, such as superalloys, hardened steels, and exotic metals.

Disadvantages of PECM:

Limited to Electrically Conductive Materials: Only works with materials that can conduct electricity.
Length-to-Depth Ratio Constraints: There are limitations in machining very deep cavities with narrow profiles.
High Tooling Costs: The initial investment for tooling and equipment can be significant.
