• HSK80 and NT50 spindle interface options are available, with some models marked as optional (選配).

Additional Notes and Customization

• Special spindle unit orders are accepted to accommodate unique specifications.
• The document references the use of Delta servo motors (model ECMA E11315) for spindle drive.
• Applications include multi-edge forming and chamfering machines, indicating versatility in machining operations.

Summary of Critical Requirements and Best Practices

• Ensure correct spindle bearing and seal configurations are used per model to maintain precision and durability.
• Maintain roundness tolerance of ballscrew to ≤ 0.003 mm for optimal performance.
• Follow specified drilling and tapping hole dimensions and depths for proper assembly and function.
• Consider weight differences when selecting models for machine integration.
• Utilize optional spindle interfaces (HSK80 or NT50) based on tooling and machine compatibility.
