It is generally acknowledged that run out can be relatively low on some hydraulic chuck systems, and this can diminish further after intensive use. However, this problem has been addressed with the new Hydraulic Chuck Jet Through that has been introduced to BIG Kaiser’s HDC series available in the UK from Tamworth-based
Industrial Tooling Corporation (ITC).
Hydraulic chucks compress an internal membrane in the holder body to apply uniform pressure around the cutting tool that optimises concentricity and minimises run out. Clamping with the new BIG Kaiser Hydraulic Chuck Jet Through chuck is easy, fast and safe. This makes it simple to change tools in the machine.
With no heat shrink clamping machines required, the life of the tool holder is extended indefinitely, saving money and reducing the environmental impact of holder replacement when compared to shrink-fit holders. Part of BIG Kaiser’s HDC (hydraulic chucks) series, the new through-coolant chuck provides precise clamping in the 4 to 12mm diameter range with the extremely accurate and innovative BIG CAPTO interface.
According to Giampaolo Roccatello, chief sales and marketing officer for Europe at BIG Kaiser, said: “The Jet Through hydraulic chucks are ideal for applications that would benefit from improved coolant delivery. By directing coolant to the cutting edge, surface finish is improved and tool life is extended.”
Produced to the high quality standards that BIG Kaiser is known for, the new chuck is well suited for all small to large machine shops that undertake precision milling where the lowest possible run out is required. The Hydraulic Chuck Jet Through is available for BIG CAPTO C5 and C6 machine spindles as well as the BBT 30/40/50, BDV40, and HSK 63 spindle interfaces.
