Application scenarios:
High speed machining center and five axis linkage equipment: used for tool internal cooling (center water/air outlet), improving the stability of deep hole drilling and milling, preventing tool breakage, compatible with HSK, BT and other spindle interfaces, with a speed range of 15000-50000 rpm.
Manufacturing of precision automotive and aerospace components, such as engine cylinder blocks, titanium alloy structural components, and turbine discs, requires continuous and stable internal cooling to ensure micrometer level accuracy and surface quality.
Automated production line and specialized gun drilling/gun hinge equipment: achieve efficient cooling and chip removal for long deep holes (aspect ratio>10), with a detachable structure for easy integration and maintenance, and support dry operation to prevent dripping and leakage.
Electric spindle integrated system: As a “fluid hub”, the built-in electric spindle synchronously completes the center liquid outlet/cooling/pneumatic tool change, requiring high dynamic balance (G1.0 or higher) and anti vibration design.
High speed transformation of old machine tools: replacing traditional leak type joints, improving spindle speed and cooling efficiency, and adapting to the upgrade needs of electric spindles above 20000 rpm
