Electrical discharge machining Wikipedia

Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject

Allowance (engineering) Wikipedia

In engineering and machining, an allowance is a planned deviation between an exact dimension and a nominal or theoretical dimension, or between an intermediate-stage dimension and an intended final dimension. The unifying abstract concept is that a certain amount of difference allows for some known factor of compensation or interference. For example, an area of excess metal may be left because

Hypothetically, could you use a lathe to make a new

Feb 18, 2021 Yes, from a theoretical perspective, a lathe features all the movement necessary to create the forms of an angular contact bearing. In practice, you are orders of magnitude below the required accuracy for the bearings. A lathe spindle is built for stiffness and utility (through bore), but lacks the low runout of precision grinding spindles.

Principles of Grinding eLearning Industrial Machining

Machines used to grind in manufacturing are called grinders, or grinding machines. Both terms refer to the same device. A grinding machine uses an abrasive product — usually a rotating wheel — to shape and finish a workpiece by removing metal and generating a surface within a given tolerance.

EP1180414A1 Grinding machine Google Patents

The time to grind a workpiece (82) can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength consideration require, and which may therefore be less than the axial length of the region to be ground. It is especially beneficial in a grinding machine (68) to employ two narrow grinding wheels mounted for independent movement towards and away from a

A High Performance CNC Machine for Grinding Camshaft

Jan 01, 1983 (4) The grinding wheel has limited life due to accuracy dependence on size. (5) The set-up time for a new profile is very long. (6) The metal removal rate varies by a factor of 500: 1 round a typical profile due to the geometry of the wheel-to-work interface. The direct grinding of camshafts using a CNC machine eliminates all of these problems.

TRUTHS AND MISCONCEPTIONS IN THE ORE COMMINUTION

In classical grinding machine, t 2 is several times larger than t 1. Grinding ma-chine is more energy efficient if the value of coefficient t 1. is lower. If V is the volume of raw materials in the workspace of grinding machine, and Q is the volume capacity of the machine, then the time of grain stay in the work-space of machine t 2 is: t 2
