Frequently Asked Questions
What is the applicable pipe range of the QG630 cutter?
It is professionally designed for ultra-large HDPE pipes with outer diameter from 250 mm to 630 mm.
What is the maximum cutting wall thickness?
It supports an ultra-high maximum cutting thickness of 65 mm, suitable for all kinds of super-thick-wall large-diameter pipes.
What is the maximum matching extrusion line speed?
The max adaptable line speed is 3 m/min, matching the stable low-speed forming process of large thick-wall pipes.
What is the power of the cutting motor?
It is equipped with a 4.0 kW high-torque cutting motor for heavy-load cutting work.
What is the specification of the cutting blade?
Heavy-duty thickened blade size: 130×45×4 mm, with high wear resistance and impact resistance.
What feeding method does QG630 adopt?
Industrial-grade hydraulic feeding system, providing stable and powerful cutting pressure for ultra-thick pipes.
What brand are the main electrical components?
PLC, touch screen and all core electrical components are original SIEMENS brand.
Can the machine cut 65 mm super-thick pipe wall stably?
Yes. The combination of high-torque motor, thickened blade and hydraulic steady-pressure system ensures smooth, flat and flawless cutting effect.
Does it support online synchronous tracking cutting?
Yes, it realizes automatic tracking, non-stop operation and precise fixed-length cutting during pipe extrusion.
What is the advantage of hydraulic feeding for large pipe cutting?
Hydraulic feeding provides stronger, more stable and continuous cutting force, effectively avoiding cutting jitter and section unevenness caused by insufficient pressure during thick-wall pipe cutting.
What is your delivery time and warranty policy?
Delivery time is 20–30 working days after deposit. We provide 12-month machine warranty (excluding wearable parts) and lifelong technical support.
