FAQ

What is the specific size range for this machine?
This series is optimized for M12 to M48 fasteners, handling clamp diameters from 12mm to 48mm and billet lengths up to 150mm, covering the highest volume market segment.

How quickly can we change over to a different nut size?
Using digital servo presets, the machine automatically adjusts stroke and timing. Combined with modular grippers, a full changeover (e.g., M20 to M24) takes under 90 minutes.

Can this integrate with our existing induction heater?
Yes, if your heater supports external PLC signaling. However, our integrated turnkey package (Heater + Machine + Press) is recommended to guarantee perfect synchronization and achieve the claimed 30% energy savings.

What is the maximum speed for M20 nuts?
For standard M20 hex nuts, the machine achieves 55–60 pcs/min. Larger sizes (M48) typically run at 25–30 pcs/min depending on material heating requirements.

Does the system support Industry 4.0 data collection?
Yes. Our PLC includes native Ethernet/IP and Modbus TCP ports, enabling seamless connection to MES/ERP systems for real-time monitoring of output, downtime, and energy usage.

What maintenance is required?
Daily lubrication of linear guides and gripper pad inspection are standard. The servo system is maintenance-free for over 20,000 operating hours. A detailed preventive schedule is provided upon delivery.
