T8 Drilling and Tapping Center

Efficient Machining: Equipped with a Yongyu direct-drive BT30 spindle (φ100) with a maximum speed of 20,000rpm, enabling high-speed drilling and tapping operations, suitable for efficient mass production of precision parts.
Stable Machine Body: Adopts HT300 resin sand castings (Model T-8) with aging treatment to effectively reduce operational vibration, ensuring stable machining accuracy.
Precision Transmission: X/Y/Z axes are fitted with PMI/HIWIN/Ina/Rexroth linear guides (Taiwan/Germany) and pre-tensioned ball screws, guaranteeing smooth and precise movement.
Flexible Tool Magazine: Standard with Taiwan Shengjie BT30-21T arm-type tool magazine, featuring a tool change time of only 1.2 seconds between adjacent tools, supporting multi-process continuous machining to enhance production flexibility.
Optional Systems: Control systems can be customized with options such as Mitsubishi M80 (Japan), Fanuc, Mitsubishi, or GSK, tailored to meet diverse production needs.

Case Study

We believe the projects that we have executed speak for themselves. CITIC HIC has engineered and provided 6 AG mills of Ø12.2m×11m (28000kW gearless drive) and 6 overflow discharge ball mills of Ø7.9×13.6m (2×9000kW gear drive) for Sino Iron Project in Australia. For Zijin Mining’s Duobaoshan Copper Mine project in Heilongjiang, we have manufactured and provided SAG mills of Ø11×6.4m (2×9000kW) and overflow discharge ball mills of Ø7.9×13.6m (2×9000kW) which have been well operating currently.
