The STFH-780 series is designed for efficient processing of complex parts, adopting a dual-spindle butt processing method. The Dual-Gantry structure provides stable horizontal movement and lightweight vertical movement. Both sides are equipped with multiple tool turrets, three-axis power heads, and multi-hole boring-drilling tool holders, capable of simultaneously performing turning, milling, boring, drilling and other processing on complex parts, achieving one-time processing completion without secondary clamping and multi-process machining.
Dual Spindle Synchronous Processing System
The STFH-780 uses two high-precision electric spindles from Taiwan Yucheng YCD200 type, with a maximum spindle bore diameter of 46mm, speed range of 50-5000 rpm, rated speed of 3000 rpm. The dual spindle design significantly improves processing efficiency, especially suitable for mass production.
The left main machine is designed with a 6-station tool turret, 3-station power head, and 6-station boring-drilling tool holder; the right side is designed with a 4-station tool turret (can be customized to 6 stations as needed), 3-station power head, and 6-station boring-drilling tool holder.
Adopting dual-spindle butt processing method, the Dual-Gantry has advantages of stable horizontal movement and lightweight vertical movement.
High Precision Rigid Structure
Using HT300 high-strength cast iron bed to ensure long-term stable operation. Imported C3-grade screw linear rails provide high rigidity and high precision motion control, Japan NSK-P4 grade angular contact bearings ensure long-term stable spindle operation.
The Dual-Gantry structure design provides excellent horizontal movement stability and lightweight vertical movement, especially suitable for high-precision processing of complex parts.
The overall structure has been optimized through finite element analysis to ensure stability during high-speed machining. The base adopts a wide design to increase equipment stability and reduce vibration impact on machining accuracy.
Multi-process Compound Machining Capability
Both sides can simultaneously perform turning, milling, boring, drilling and other processing on various complex parts, achieving one-time completion of complex parts processing without secondary clamping and multi-process machining. Significantly improves part machining accuracy and efficiency.
Equipped with a Shindengren dual-channel controllable 10-axis high-end CNC system, capable of simultaneously controlling multi-axis linkage to achieve high-precision machining of complex surfaces.
The tool magazine design is reasonable with short tool change time, improving overall equipment utilization.
Especially suitable for pneumatic industry, explosion-proof industry, sealing industry and various complex parts processing requirements.
