Description:
The T7 Taiwan Spindle BT30 CNC Drilling Tapping Machine is a high-precision, high-efficiency vertical CNC machining equipment, featuring a core Taiwan-originated BT30 spindle that serves as the "heart" of the machine, ensuring stable and accurate machining performance. Designed with a robust Meehanite cast iron body adopting an A-line ribbing and cabinet structure, the machine boasts exceptional shock absorption, bending resistance, and rigidity, effectively reducing vibration during high-speed operation and maintaining long-term machining accuracy. The BT30 spindle taper, paired with a direct-drive transmission system, achieves a maximum speed of up to 24000 rpm (optional), with low centrifugal force and expansion coefficient, enabling precise drilling and tapping operations even at high speeds.
