Machinable Ceramic Rod 3/4″ x 3″ Corning Zero Porosity Tight

Description

Product Overview

The Corning Machinable Ceramic Rod is engineered for demanding applications where dimensional accuracy, material stability, and clean machining are paramount. Measuring 3/4″ in diameter and 3″ in length, this rod combines a dense, zero‑porosity ceramic matrix with exceptionally tight tolerances of +0.015″/‑0.000″ on diameter and a saw‑cut length on the plus side. The material is sourced from Corning Inc., a trusted name in advanced ceramics, ensuring consistent quality across each batch. Its composition eliminates outgassing, a critical factor for vacuum environments, high‑temperature processes, and precision instrumentation. The rod’s weight of 2.24 ounces makes it easy to handle while providing the robustness required for high‑stress machining operations. Designed for immediate integration into manufacturing workflows, the rod requires no post‑firing, reducing lead times and simplifying inventory management. Whether used in aerospace component fabrication, semiconductor equipment, or custom scientific apparatus, this ceramic rod delivers the reliability and performance that engineers demand.

Usage

In industrial settings, the Machinable Ceramic Rod excels in applications that require both precision and chemical inertness. Its zero‑porosity structure makes it ideal for use in vacuum chambers, where any outgassing could compromise system integrity. The rod is frequently employed as a spacer or guide in high‑temperature furnaces, optical assemblies, and gas flow regulators, where its stability under thermal cycling ensures consistent performance. In scientific research, the rod serves as a substrate for sensor mounting, a core for custom probe fabrication, and a component in micro‑machined devices that demand exact dimensional control. The material’s machinability allows for rapid CNC milling, drilling, and turning without the need for specialized tooling, reducing production costs and turnaround time. Additionally, the rod’s chemical resistance enables use in corrosive environments, such as chemical processing equipment and laboratory apparatus, where metal components would degrade. Its compact size and lightweight nature also make it suitable for portable testing rigs and field‑deployed instrumentation, providing a durable yet manageable solution for on‑site engineering challenges.

FAQ

What machining processes are recommended for this ceramic rod?

The rod can be machined using conventional CNC milling, turning, and drilling operations. We recommend using carbide or diamond‑coated tools to achieve the best surface finish and to minimize tool wear. Coolant should be applied sparingly to avoid thermal shock, and feed rates should be adjusted to accommodate the material’s hardness while maintaining the tight tolerances specified.

Is any post‑processing required after machining?

No post‑firing or additional heat treatment is necessary. The rod arrives fully sintered and ready for immediate use. After machining, a light ultrasonic cleaning can be performed to remove any debris, ensuring the surface remains free of contaminants for sensitive applications.

Can this rod be used in vacuum chambers?

Yes. The zero‑porosity composition eliminates outgassing, making the rod suitable for high‑vacuum environments, including semiconductor processing equipment, space‑flight hardware, and scientific instrumentation that require ultra‑clean conditions.

What is the temperature range the rod can withstand?

The ceramic material is stable up to approximately 1,600°F (870°C) without degradation of its mechanical properties. This makes it appropriate for high‑temperature furnaces, thermal cycling tests, and other applications where thermal resilience is essential.

How does Corning ensure the consistency of each rod?

Each batch undergoes strict dimensional inspection using calibrated metrology equipment, as well as density and porosity testing. The manufacturing process includes controlled sintering cycles and quality checkpoints to guarantee that every rod meets the advertised tolerances and material specifications.
