What is the thermal expansion tool holder?

The principle of thermal shrinkage TOOL HOLDER is to use the difference of thermal expansion coefficient between the Tool Holder and the tool to clamp the hot-charging system of the tool strongly. The system uses the tool handle heat shrinkage machine for heating and clamping, and the tool loading and unloading is simple and convenient. There are no nuts and components required for the clamp in the tool installation section. Simple, efficient and slender head shape of the tool holder can make the length of the tool prominent set more practical, and can better reflect the advantages of the thermal shrinkage tool holder in the deep cavity processing. The clamping stability in high-speed processing and high concentricity can maintain higher processing accuracy.

Compared with other tool holders, the tool holder material has higher thermal expansion coefficient, which can realize low temperature thermal clamping and thermal removal. No matter how many times the hot clamping is carried out, the material quality will not change and the accuracy of the tool handle will not deteriorate. The high rigidity tool has short protrusion and does not need nuts and barrel clamps for clamping tool by barrel clamp type tool holder. It is an integral form consisting of body only, with a half angle of 3 degrees and a wall thickness of 1.5mm. It is a very light and slender shape, avoiding interference with workpiece as far as possible.

It can carry out high rigidity, strong and stable cutting, no flutter, get high quality processing surface, high precision when jumping, effectively prolong tool life, no fastening parts (nuts, clamps, etc.), regardless of proficiency, can accurately and accurately install: because it does not need to adjust the degree of clamping, can be high precision safety. Tool loading and high precision clamping can prolong tool life and high durability. After many processing tests, the same tool handle will not change its accuracy even if it is hot loaded and unloaded more than 2000 times, and its stability is stable and reliable.
