Rozdíl mezi vřetenem řady HSK a modelem BT o stabilitě

Já. Přehled: HSK series and BT spindles are common configurations in CNC machine tools, which are used to support and drive tools for cutting. However, there are some differences in their design and application, which affect their stability performance.

II. Features of HSK series: HSK series spindle is famous for its high stability and high precision. Its design is compact and rigid, suitable for high-speed cutting applications, and adopts a double positioning system with 1:10 taper and end-face contact. Elastic deformation is realized through the hollow thin-wall design to ensure that the high-speed lower cone surface and the flange end surface fit closely at the same time. The HSK series spindle adopts a unique interface design, which makes the connection between the tool and the spindle stronger and reduces the vibration and deformation in the cutting process. Navíc, the cooling system of the HSK series spindle can effectively control the thermal expansion and maintain the thermal stability of the spindle.

III. Features of BT spindle model: BT spindle is well-known for its good versatility and wide application. It adopts a 7:24 taper design and is in contact with the spindle through the cone surface, which is a single-sided positioning system. The rigidity is relatively low, especially when rotating at high speed. The expansion of the spindle hole will cause the position of the tool and shank to shift, affecting the processing accuracy of the product. The BT spindle adopts a standard interface design and is compatible with most tools on the market. The advantage is that it is easy to replace the tool and relatively easy to debug and maintain. Navíc, the cooling system of the BT spindle may not be as advanced as the HSK series, and the thermal stability is slightly worse.

IV. Stability comparison: In terms of stability, the HSK series spindle shows higher stability. Its compact design and excellent rigidity enable it to maintain low vibration and deformation during high-speed cutting. Although the BT spindle has a wide range of applications and simple maintenance, it may show certain flexibility in high-speed cutting, affecting machining accuracy and surface quality.

V. Differences in practical applications: In practical applications, HSK series spindles are usually used in high-precision and high-speed cutting applications, such as mold manufacturing, aerospace and other fields. The BT spindle is more widely used in general machinery, automobile manufacturing and other industries, and its wide application range and simple maintenance characteristics have been widely recognized.

VI. In summary, HSK series spindles show advantages in stability and high accuracy, and are suitable for high-speed cutting applications. The BT model spindle is widely recognized for its versatility and simple maintenance. In practical application, the appropriate spindle type can be selected according to specific needs and processing requirements.
