Machining graphite components

2019/5/15The various forms and fixtures used in vacuum furnaces and various sintering operations nearly all require graphite. Machining some of these graphite components can present challenges. Two of the most common challenges are: Furnace components: Heating

Laser machining of graphite

Laser machining of graphite-, Kevlar- and glass-fiber reinforced epoxy composites were investigated with particular emphasis on laser parameters, cutting speed, quality of cut, gas emission and thermal damage. A computer numerically controlled CNC stage and a 2.8 KW, RF excited, carbon dioxide laser were used for the study. It is shown that glass and Kevlar reinforced composites can be

The machinability of a cast aluminium alloy

1988/6/1Conclusions (i) The machining forces for A1-Si alloy- graphite composite are less than those for a similar material without graphite partly because of lower tool-chip friction but more importantly because of a lower shear flow stress.

Graphite

Carbonization of molded graphite: carbonizing (also known as baking) the green shape is the next step. Carbonization takes place in a furnace in an inert or reducing atmosphere. The process may last from a few days to several weeks depending on the constituents, and the size and geometry of the part. The temperature is raised slowly to 600C, at which stage the binder softens, volatiles are
