verktygselektrod

Verktygselektrod is a Swedish term that translates to "tool electrode" in English. It refers to an electrode used in various electro-chemical machining processes, particularly in electrical discharge machining (EDM) and electrochemical grinding (ECG). These electrodes are typically made of conductive materials like graphite, copper, or copper-tungsten alloys, chosen based on the specific application and workpiece material.

In EDM, the verktygselektrod is used to erode material from a workpiece by creating a series of electrical sparks. The shape of the verktygselektrod directly determines the shape of the cavity or feature produced on the workpiece. Precision and durability of the verktygselektrod are crucial for achieving accurate and repeatable results in manufacturing.

In electrochemical grinding, the verktygselektrod, often referred to as a grinding wheel, facilitates a controlled electrochemical reaction. The workpiece is immersed in an electrolyte, and a DC voltage is applied between the verktygselektrod and the workpiece. This causes the metal to be removed electrochemically, aided by the abrasive action of the verktygselektrod. Verktygselektroder in this context are often metal-bonded diamond or other abrasive particles.

The design and manufacturing of verktygselektroder are specialized fields, as their performance significantly impacts the efficiency, accuracy, and surface finish of the machined part. Factors like electrode wear, electrical conductivity, thermal properties, and mechanical strength are critical considerations.
