Machining Process Capability: From Ceramic Concept to Production

With over 15 years of ceramic developing experience, JSK Industrial Supply works with you on any product you need from prototype development to resolving any issue. In every case, you’ll speak with the same person when you contact us as we work toward fulfilling your order.

Press to Shape

Typically, when referring to ceramic parts that are pressed to shape, it means parts that have their net shape coming off of the tooling. The only additional work for you is what is needed to fit the parts into your application. Most of our customers add value to our product via metallization or some type of assembly.

Green Machining

Green machining is a term used for machining ceramic material prior to firing. This operation allows us to add additional configurations to a part that has been either dry pressed or iso-pressed, which you normally could not obtain by these operations directly. These configurations could be in the form of multiple-stepped I.D.s and O.D.s as well as notches, cutouts, holes, or some type of shape on the sides of these already-formed green parts.

Post-Firing Grinding

This term refers to grinding after the firing process. Once this material is fired, the only thing harder is diamond. The only way to change the shape or size of a fired part is to grind, ream, or hone it with some type of impregnated diamond tools, such as wheels, reamers, or hones. Ceramic parts can be reamed or ground after firing to achieve a closer tolerance than what can normally be achieved prior to firing.

CNC Machining

Hi-Tech Ceramics is always pursuing to have the best precision tolerance and production. Making production or custom components are just some of the benefits of C.N.C. machining in ceramics. Hi-Tech Ceramics, in developing this capability, has assured its customers of the foremost technology in the fabrication of ceramics.

JIG Grinding

Leading the industry with the best quality components needing JIG grinding of advanced ceramics. The capabilities of Hi-Tech Ceramics is endless with tolerances of +/-.0002 and better depending on customers specifications. Some of the skills offered by Hi-Tech Ceramics are performing tapered holes, slip fits, 0% chipped circuit board holes.

Surface Grinding

Hi-Tech Ceramics performs amazing work for surface grinding, utilizing excellent craftsmen to surface grind any type of advanced ceramic materials with tolerances of +/-.0001 and up to 18 inches in length. JSK industrial Supply I has several centerless grinders that allow us to hold tighter tolerances on the O.D. We also have an O.D./I.D. grinder that allows us to accomplish this same task. We have reamed numerous I.D.s holding tolerances to ± .0005.

I.D/O.D. Grinding

Many skills are offered with I.D. and O.D. grinding, we can utilize our machines to fit any drawings specifications to custom making tools to fit any need for our machines. We can work on the simplest and to the most extract components out there in the market Hi-Tech Ceramics can perform and deliver the best ceramic components needed for the market today.

Centerless Grinding

Centerless Grinding capabilities for Hi-Tech Ceramics is important, due to the high demands of tight tolerance components, customer’s need today. Hi-Tech Ceramics centerless grinding tolerances are +/-.0001 up to 14 inches in length.

Slicing

From production components to custom Hi-Tech Ceramics does it all. With excellent, and precise tooling we can offer endless options to fit any customer’s specific, and precision parts at a very reasonable turn around time.

Lapping

Lapping is a skill done by our craftsmen here who have years of experience, who can take your components and give them a great finish. Let JSK Industrial Supply give your components an unbelievable finish with reasonable pricing and turn around time.

Glazing

Glaze is generally considered to be a thin, glassy coating fired onto the surface of a ceramic form normally as a secondary process. Originally, the glaze was used to help prevent porosity on the outer surface of the fired ceramic body, which would, in turn, prevent the surface from becoming dirty or collecting any metallic substances. With some materials, glaze is still used for the same reasons, but with most of the fully fired alumina’s, this is no longer the case. We believe that some of our customers are still using glaze because it has been specified on some type of government drawing or strictly for appearance sake.

Typically, we have been supplying all high-temperature glazes. These are glazes that will withstand the temperatures necessary for the metallizer to complete their process without deteriorating the glaze. They are normally good at temperatures around the range of 2500°F. A low-temperature glaze can be applied to all of the alumina bodies and will normally sustain temperatures in the 1400°F to 1600°F range. As a general rule of thumb, we use the higher temperature glaze to be sure to cover the customer’s maximum temperature range.

Colorization

There are three basic colors we can produce that will maintain their color integrity through the high-temperature firing: purple, blue, and black. These colors can be produced in ranges to give you a spectrum from a light pink to a dark purple and from a light blue to black. Reasons for colored ceramics can vary from being able to recognize a white material, such as yarn or thread passing over a purple alumina, or for a visual color contrast, or for cosmetic reasons.
