Low Stress Grinding Electrochemical Grinding is preferred as compared to conventional grinding Deep hole with small hole diameter e.g. 1.5 mm hole with l/d = 20 Machining of composites. Abrasive Jet Machining In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity.
Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour of the workpiece. 5. •In this process the abrasive lead and grinding field is connected to cathode and the work piece is connected to the anode. 6.
• Electrochemical Discharge Machining (ECDM) process is mostly applied for micro-machining and scribing hard and brittle, non-conducting materials like glass, quartz, ceramics etc. • The work first on the Electrode effect, anode or cathode effects reported by Fizeau and his group of researchers and Foucault and his co-researchers in 1844.
Chemical milling 1. In chemical milling, shallow cavities are produced on plates, sheets, forgings and extrusions. 2. The two key materials used in chemical milling process are etchant and maskant. 3. Etchants are acid or alkaline solutions maintained within controlled ranges of chemical composition and temperature.

Grinding fixtures should be used when regrinding drills. For best results in grinding high-speed steel drills, medium-grain, soft-grade dry wheels should be used. Blueing or burning is to be avoided, as is quenching. Quenching will often check or crack the drill if it has been overheated. 46 Fig. 4. Suggested geometries for drills used on ...
Electrochemical machining includes polishing, electroplating, electro etching and electrochemical grinding. Compared with the traditional processing methods, there is a great advantage. And the future electrochemical processing is toward the development of micro system, nano materials synthesis, has a very high application prospects.
Electrochemical grinding greatly reduces this wheel wear. Fragile parts (honeycomb structures), surgical needles, and tips of assembled turbine blades have been ECG-processed successfully. The lack of heat damage, burrs, and residual stresses is very beneficial, particularly when coupled with MRRs that are competitive with conventional grinding ...

In electrochemical processes, an input of electrical energy drives CO 2 conversion reactions in an electrolytic cell in which CO 2 is reduced on the cathode while oxygen evolves at the anode. CO 2 can be converted to a range of fuels and fuel precursors by this means, including CO, formic acid (HCOOH), methane (CH 4 ), and ethylene (C 2 H 4 ).
