Grinding Process Discharge

The discharge is supported by a dielectric liquid [2], which in combination with the rotation of the disc helps to cool the process and carry away the removed material while the disc is moved over the workpiece. The spark gap [3] makes the machined surface is slightly below the disc's outer diameter.

The article describes the process characteristics of the EDG in terms of applications, surface finish, corner radius, and wheel wear. It concludes with a graphical illustration of the effect of heat in electrical discharge grinding on the surface hardness of various work metals.

Electrical discharge grinding (EDG) is a hybrid process involving energy of sparking as well as mechanical grinding. The machining of thin and fragile material is very difficult for manufacturing industries and rapid demand of requirement could not

grinding process discharge Electrical discharge machining - Wikipedia Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks).[1]

INTRODUCTION WEDG (wire electro discharge grinding) technique is a special version of the micro WEDM method that was introduced firstly by Masuzawa et al. (1985) The WEDG process is considered as a finishing process where the purpose is to obtain good surface quality In WEDG no mechanical contact nor cutting is necessary for surface finish.

The process parameters selected for both processes were duty cycle, discharge current, pulse on time, grinding wheel speed, work speed, and speed ratio to study their influence on responses like ...

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 ...

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.

This process is applicable to very selective materials. Here, the materials of the workpiece as well as the grinding wheel must be conductive. Some of you may be looking for applying this process to the workpieces that have cavities. But the bad thing is that you cannot use this process …

as metal cutting using different tools and grinding is that this technique utilises thermoelectric process to erode undesired materials from the workpiece by a series of discrete electrical sparks between the workpiece and the electrode. A picture of EDM machine in operation is shown in Figure 1. Figure 1: Electrical discharge machine

discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow. The slurry stream is classified at Cyclone 1 with the overflow going to the flotation circuit.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

01-11-2013· In this work, process physics based mathematical model has been developed by assuming that the material removal in electric discharge machining is due to EDM and grinding actions. The extent of influence of the two processes has been modeled by weighted sum of material removal and the weights are obtained based on processing conditions which gave different class of surface morphologies.
