Overcut in pulsed electrochemical grinding A Fadaie

The electrochemical grinding (ECG) process offers a number of advantages over conventional grinding, such as low induced stresses, large depths of cut, increased wheel life and the ability to machine delicate workpieces. However, one disadvantage is the difficulty of controlling the dimensional accuracy of the workpiece. In the present work the use of pulsed voltage in ECG is investigated for

Electrochemical grinding Wikipedia

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour of the

GRINDING FEEDS AND SPEEDS

High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels. On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of high

How to control the surface roughness of WEDM workpiece

The feed rate can also affect the surface roughness, so the feed rate should be appropriate. Low feed speed will affect the efficiency, high feed rate is easy to break or burn wire. In order to solve this problem, Baoma CNC has developed for many years, which makes the feed speed of Baoma CNC wire cutting machine from slow to fast. When the processing current reaches 75% 80% of the short
