Spindle Clamp Guidelines
Precision mounts for CNC applications! Explanation of spindle holder requirements.
When installing a high-speed spindle without a flange, please adhere to the following requirements to ensure secure clamping, suitable precision, and an extension of the spindle's service life. 1. The clamping length should be as long as possible to evenly distribute the force. 2. To prevent slipping and stress concentration, the minimum clamping length must exceed 1.5 times the spindle's outer diameter (1.5×D). 3. The hole tolerance of the fixture must comply with ISO H6 to fit the spindle's outer diameter ISO h6, ensuring a precise and stable connection. 4. Geometric accuracy requirements for the spindle holder: - Cylindricity error ≤ 0.01 mm - Concentricity error of the hole ≤ 0.01 mm 5. To balance the clamping and reduce the risk of deformation, a dual half-shell fixture design is recommended. 6. To improve assembly tolerances, it is advisable to provide a clearance of 0.01 to 0.02 mm in the central fitting zone. *For detailed content of the article, please refer to the related links.
