The 2-jaw hydraulic chuck are specialized workholding devices designed for efficient and precise machining of long, slender workpieces. They offer a combination of high-speed capabilities, powerful hydraulic clamping, and a hollow bore, making them ideal for applications where through-spindle coolant or bar feeding is required.
2 Jaw Chuck
Key Features:
High Speed: The powerchuck are engineered to handle high rotational speeds, enabling rapid machining cycles and increased productivity.
Hollow Design: The hollow bore allows for the passage of long workpieces or bar stock through the spindle, facilitating continuous machining operations.
Powerful Hydraulic Clamping: Hydraulic clamping provides strong and consistent gripping force, ensuring secure workpiece holding even at high speeds and under heavy cutting loads.
