(Incl. Tax: €196.54)
The SCHUNK CELSIO thermal shrink chuck with Cool Flow technology delivers outstanding performance through its induction heating system, creating a perfect connection between tool and holder. It achieves exceptional precision with runout ≤0.003 mm and maintains G2.5 balance up to 25,000 rpm. The Cool Flow version features two dedicated coolant channels that direct coolant straight to the cutting zone for optimal cooling. Compatible with automatic tool changers, it offers h6 tolerance on tool shanks and ISO 7388 AD/AF coolant supply. The system includes axial adjustment and balancing screws (excluding Ø3-5mm diameters), ensuring maximum precision for all applications.

The SCHUNK CELSIO thermal shrink chuck is a technologically advanced solution designed for effective tool mounting. It features an innovative Cool Flow technology that significantly enhances machining efficiency by promoting better heat management during processing. Engineered for use with SK40 and SK50 shanks in compliance with DIN ISO 7388-1 AD/AF standards, it incorporates a specially designed "Cool Flow" coolant passage system. This system enables highly efficient cooling directed precisely to the cutting zone, which not only improves the quality of machining work but also extends the lifespan of the tools being utilized.
One of the standout features of the CELSIO chuck is its induction locking mechanism, which ensures an extremely precise connection between the tool and the holder. It achieves outstanding runout values of ≤0.003 mm, making it exceptionally suitable for applications that demand a high level of surface finish and strict tolerances. The chuck is balanced according to G2.5 standards, allowing for stable operations at high speeds of up to 25,000 rpm without sacrificing system stability.
The Cool Flow version is equipped with two dedicated coolant channels that direct coolant straight to the cutting area for optimal cooling performance. It is also compatible with automatic tool changers and maintains h6 tolerance on tool shanks while providing ISO 7388 AD/AF coolant supply. Additionally, the system includes axial adjustment and balancing screws (excluding diameters of Ø3-5 mm), guaranteeing maximum precision for various applications.
