Ceramic Machining and Firing Accuratus
maintains a fabrication facility and network of suppliers to meet your
research, developmental and production quantities for ceramic
components. Production lots of one piece prototypes through multi-year
contracts for thousands of parts can easily be accommodated. A full
complement of measurement instruments and a quality assurance system
based on the operating characteristics defined in ANSI/ASQ Z1.4-1993
ensure you receive good products. Diamond Grinding of Ceramics
Accuratus has a full complement of grinding equipment for the machining
of hard materials. Precision dimensional tolerances of 5 microns
(.0002") and surface finishes of 0.2 microns (8 microinches) are
routinely maintained during production. Tighter tolerances are
available where required subject to careful review by our engineering
and production departments. Services offered include surface grinding,
dicing, OD grinding, ID grinding, centerless grinding, hole drilling
(especially high aspect ratio holes), jig grinding, lapping, honing and
polishing. A full complement of manual and CNC machine tools are
available to meet your component needs. Multiple
tooling vendor relationships are maintained to assure a steady supply
of cutting tools. Where special requirements exist, custom tooling is
obtained to meet your special situations. Under all circumstances, our
working knowledge of ceramic materials and our knowledge of your
application are relied upon to ensure we are using grinding techniques
that minimize damage to the ceramic workpieces thus assuring you
receive the highest strength components available. Green Machining of Ceramics
Accuratus green machines several oxide compositions where appropriate.
Green machining techniques are used to reduce cost especially where
large amounts of material must be removed. Tolerances typically
achieved after firing the green machined parts are + .15mm (.006") or +
1% of nominal dimension-whichever is greater. Techniques ordinarily
used include milling and lathe work. Finish diamond grinding can be
employed after firing to improve tolerances where needed. Firing Ceramics
Facilities for air firing ceramic up to 1650°C are available at
Accuratus. Electric kilns with tightly controlled temperature profiles
are employed. Standardized firing schedules are used for our ceramic
ware, however firing schedules can be customized to meet your special
situations. See also: Working Together > Custom Component Manufacturing Standards
