Shrink-Fit Holders

Seenu Precision Tooling offers Shrink-Fit Holders. These are clamped by inserting into a holder that is expanded by heating. Heating is carried out in a hot air device or inductive type equipment. Once the tool is inserted into holder the heater is switched off and the assembly is cooled with a blow of air. The tool holder with the rigidly fixed tool is now ready for use on the machine. After use, the tool is removed by the same process of heating the assembly and removing the tool. Generally, hot air heaters are used for solid carbide shank tools only. Other wise, removal of the tool from the assembly becomes impossible with the same coefficient of thermal expansion for the steel holder and HSS tools.
