Direct assembly of tool and heat shrink tool holder: No additional fasteners or connecting components are used. Based on the taper of the tool holder, the runout at 4 times the diameter is within 0.003mm. The high-precision heat shrink tool holder holds the tool securely, enabling ultra-precision machining, resulting in significant improvements in both the machined surface and tool life.
High stability: The same tool holder can be reused more than 3,000 times with good precision retention. Heat shrink tool holders made of steel may exhibit carbon buildup after approximately 2,000 uses, but with timely cleaning, the holding precision remains excellent. Tool holders made of stainless steel do not experience carbon buildup, maintaining excellent holding precision throughout their lifespan.
High clamping force: The clamping force of a heat shrink tool holder is 2.5 times that of a collet tool holder. Compared to collet tool holders, heat shrink tool holders provide stronger and more reliable clamping force.
The tool holder uses the principle of thermal expansion and contraction to achieve tool clamping.
During tool installation, the heat shrink tool holder is heated using a heat mounting machine. Once the holder is heated, the inner diameter expands, allowing the tool to be inserted. After the tool holder cools, the inner diameter contracts, tightly clamping the tool.
Heat shrink tool holders directly clamp the tool, with no intermediate mechanical components such as collets or nuts. As a result, heat shrink tool holders feature high precision, excellent dynamic balance, strong clamping force, and rigidity, making them ideal for high-speed machining.
Bright-Tools' heat shrink tool holder is a high-precision, high-stability tool holding solution specifically designed to meet the precision machining needs of modern high-end manufacturing industries. Using advanced heat shrink technology, Bright-Tools' heat shrink tool holder expands when heated and contracts upon cooling, firmly clamping the tool and ensuring extremely high stability and rigidity during the machining process.
