Thermal Insulation Sleeve: Length 50-200 mm, ID 15-40 mm

Component Specifications

Definition

A precision-engineered cylindrical component designed to isolate thermal energy generated during machining processes in capillary or wedge tool holders. It maintains temperature stability by creating a thermal barrier between the tool holder body and adjacent machine elements, preventing heat-induced dimensional changes and protecting temperature-sensitive components from thermal degradation.

Working Principle

Operates through thermal resistance principles using low-conductivity materials and air gaps to minimize heat transfer via conduction, convection, and radiation. The sleeve's geometry and material properties create a thermal break that reduces heat flow from the tool holder to surrounding components while maintaining structural integrity under mechanical loads.

Materials

High-temperature ceramic composites (alumina-silica), aerogel-infused polymers, or multilayer stainless steel with vacuum insulation. Typical specifications include: operating temperature range -50°C to 1200°C, thermal conductivity <0.5 W/m·K, compressive strength >50 MPa.
