Abstract
Electrochemical Grinding of Titanium-Containing Materials
Highlights
A large group of hard materials features an extensive collection of those troublesome when machined by conventional methods. Engineers label such materials as “difficult-to-cut”. They are characterized by the following features: extensive mechanical strength of material maintained in high temperatures, relatively low thermal conductivity resulting from a characteristic structure, which naturally hinders free heat transfer
Hybrid processes have been examined in several R&D centers
In the course of literature review, no cases comparing the work of a good quality conventional grinding machine and grinding medium with a good quality electrochemical grinder with values set suitably for machining titanium-based materials, were found
Summary
A large group of hard materials features an extensive collection of those troublesome when machined by conventional methods. Machining of difficult-to-cut materials is associated with rapid cutting tools’ wear. It results both from the structure of the tool and workpiece. Large cutting force, rapid tools’ wear, high temperature, and relatively thin and fragile walls of the machined object, may often result in deformations. In case of demanding elements, electrochemical grinding (ECG) is applied. It is a type of a hybrid process combining various types of effect upon the workpiece. In case of ECG, the flow of electrical current through the workpiece is a prerequisite
