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.
