How to Choose a BT30 ATC Spindle
BT30 is a practical interface for compact machining centers and applications that need a balance of tool capacity, speed, and rigidity.
Direct answer: Lingyu's listed BT30 range includes 5.5kW and 7.5kW configurations. Choose between them using cutting load, material, duty cycle, tool diameter, target speed, and required torque. Confirm exact SKU data before ordering.
BT30 compatibility checklist
| System | Questions for the machine builder |
|---|---|
| Tooling | Which BT30 holder, pull stud, gripper, and magazine standard is required? |
| ATC mechanics | What drawbar stroke, clamping force, and tool-change clearance are available? |
| Control | Are sensor voltage, PNP/NPN logic, speed reference, and fault inputs compatible? |
| Thermal system | Is air or water cooling maintainable at the intended duty cycle? |
| Cutting load | Is the 5.5kW or 7.5kW configuration appropriate for the actual material and tool? |
Applications
BT30 systems are commonly evaluated for aluminum milling, compact metalworking centers, mold and die work within the machine envelope, and high-speed general machining.
