We’re proud to announce that a complete CNC neck-threading machine set is now ready for shipment to Iran, following a successful inspection for one of the most reputable CNG and oxygen cylinder manufacturers in the region. This delivery marks another milestone in our company’s mission to provide precision machining solutions for global gas-cylinder production lines.
Proven Expertise in Neck-Threading Technology
With over 17 years of dedicated experience, we specialize in the design and manufacture of CNG cylinder neck-threading machines. Our equipment integrates every critical step of the process — sawing, drilling, outer and inner turning, chamfering, and threading — ensuring smooth and efficient production with excellent consistency and dimensional accuracy.
Complete Two-Machine Solution for Seamless Workflow
The set includes:
-
Neck Sawing & Drilling Machine
-
CNC Neck-Threading Machine
Together, they deliver a continuous and synchronized workflow, improving throughput and reducing downtime. This dual-machine setup offers a cost-effective and space-saving production solution tailored for high-volume cylinder manufacturing.
High Efficiency with Reliable Cycle Times
Our machines are engineered for speed and reliability:
-
Sawing & Drilling: ~120 seconds per PZ27.8 (W28.8) cylinder
-
Threading: 150 – 165 seconds per cycle
These optimized cycle times enable manufacturers to maintain stable, high-output production without compromising on accuracy or tool life.
Wide Machining Range for Versatile Cylinder Production
The system covers cylinder diameters from Ø 232 mm to Ø 406 mm and lengths from 400 mm to 2000 mm, compatible with nearly all standard CNG cylinder models on the market. Whether for automotive CNG or industrial oxygen applications, this flexibility ensures outstanding adaptability.
Precision and Control You Can Trust
Every detail matters in neck-machining. The threading system supports max outer turning up to Ø 52 mm and inner drilling up to Ø 35 mm, compatible with PZ27.8 (W28.8) and 1-1/8-12UN thread standards.
Both machines are equipped with advanced control systems for repeatable, high-precision operations:
-
Beijing KND 1000M-Ci servo control on the sawing and drilling unit
-
KND K1000T 5-axis CNC system on the threading machine
These intelligent controls ensure stable performance, easy operation, and perfect synchronization with other production-line equipment.
