The heat shrinkable tool handle works using the principle of thermal expansion and cold contraction. A thermal sensing device is used to heat the clamping part of the tool handle within a short period of time, expanding the inner diameter of the tool handle, and then immediately installing the tool into the tool handle. When the tool shank cools and contracts, it can impart uniform pressure to the tool clamping surface, resulting in a high radial clamping force that firmly clamps the tool without any mechanical clamping components intervening between the tool and the tool shank. Hot setting tool handles can solve extremely important problems such as balance, runout accuracy, and clamping strength in high-speed finishing.
① The uniform clamping force makes the tool runout very small (≤ 0.003mm).
② Large clamping force.
③ Compact and symmetrical structure, small overall size, suitable for deep cavity processing.
④ Able to adapt to high-speed rotation.
⑤ Suitable for finishing and rough machining.
⑥ The tool shank is fully and firmly connected to the jacket, and cutting fluid can only flow from the cooling hole to the tool.
⑦ Heat shrinkable tool holder technology can improve cutting speed and feed rate, while improving the quality of the machined surface, increasing the life of the tool and spindle.
