Machining Ceramic Parts On Petroleum Machinery
Machining (when needed) is a process step in Ceramic’s
manufacturing, reducing the complex ceramic part from the near-net shape to its final tolerances. When machining is required, it can occur
at two points during the production process. The point at which
machining occurs determines the specific process used.
Machining Green Bodies Certain features can be machined into a
green-body, or a bisque-fired ceramic part before firing it to its
full density. Green body machining is done using tool steel cutters
and conventional methods. Features Ceramic commonly machines into
green-bodies include:
§ Holes
§ Undercuts
§ Other special configurations
Fine Diamond Machining Full Density Parts Ceramic parts fired to
their full density are too hard for machining with tool steel
cutters or even conventional methods. Following a final firing,
when as-fired tolerances are not sufficient, fine diamond machining
(grinding) using diamond impregnated cutters is often required.
Features Ceramic commonly fine diamond machines into fully fired
ceramic parts include:
§ Diameters and surfaces that have tighter tolerance requirements
than can be achieved in the as-fired condition
§ Ceramic tubes and special extruded rods requiring fine features
or tolerances
Also, fine diamond machining is used at Ceramic to machine non
ceramics, including quartz.
No Machining All – Depending upon the requirements of the custom
ceramic part, the geometry and final tolerances can often times be
achieved during the near-net shaping, injection molding process. This is the most cost effective solution. Features Ceramic
commonly achieves with no machining whatsoever include:
§ Fully functional ceramic screw threads
§ Square holes that cannot be machined
§ Specific radii and fillets
§ Other complex geometries that cannot be machined
Ceramic Grind Blanks and Ceramic Parts Prototypes
Ceramic manufactures its own grind blanks, insuring an
uninterrupted supply and the versatility to produce virtually any
type or formulation of ceramic blank required. When delivery time
is tight, having our on blanks always available, Ceramic may be
able to grind a ceramic part complete instead of making a molding
tool.
Industrial Ceramic Intriduction
Aluminium Oxide, Al2O3 is the most widely applied and cost
effective technical ceramic material. It offers a combination of
superior mechanical strength and electrical properties, wear
resistance and corrosion resistance. The maximum working
temperature is up to 1700 °C with relatively high thermal
conductivity. It is also an electrically insulating material with a
high electrical resistivity. The good corrosion resistance makes it
insoluble in water and slightly soluble in strong acid and alkaline
solution.
