HSK63A and HSK63F are two specific types of interfaces specified by the HSK standard.
HSK63A is a tool shank with a tapered interface that features a 63 mm diameter at the large end, and a taper angle of 30 degrees. It is a medium-sized interface that is commonly used in CNC machining centers, milling machines and other types of machine tools. It is known for its high accuracy and stability, and it is suitable for a wide range of cutting tools.
HSK63F is a tool shank with a tapered interface that also features a 63 mm diameter at the large end, but with a taper angle of 45 degrees. It is a larger and heavy-duty interface compared to HSK63A and is used in high-performance and heavy-duty machine tools. It is suitable for larger and heavier cutting tools, such as face mills and shell mills. It offers higher rigidity and less tool deflection during machining.
The HSK standard also specifies the dimensions, tolerances, and other technical requirements for these interfaces, which ensure that tool holders can be securely and accurately connected to machine tool spindles.
