The Double-Station Integrated Sawing and Drilling Machine is designed for efficient neck cutting and hole drilling of seamless gas cylinders. By combining two essential processes into one automated system, this machine helps cylinder manufacturers improve production efficiency, reduce labor costs, save workshop space, and achieve stable processing quality.
It is suitable for seamless gas cylinders with diameters from Φ219 mm to Φ406 mm, lengths from 680 mm to 2300 mm, and single-cylinder weight up to 300 kg. The machine supports drilling diameters of Φ10–35 mm, neck sawing diameters of 0–80 mm, and drilling depth up to 70 mm. Two models are available: SGJZ-279 and SGJZ-406, covering different cylinder diameter ranges.
High-Efficiency Double-Station Operation
One of the biggest advantages of this machine is its double-station synchronous design. One station performs bottle neck sawing, while the other station carries out drilling at the same time. The two processes do not need to wait for each other, which greatly improves the overall production rhythm.
For continuous mass production, the machine can process approximately 500–600 cylinders per 10 hours. For standard workpieces such as PZ27.8 with a neck outer diameter of Φ48 mm, the full cycle including loading and unloading takes about 60 seconds, while the pure sawing process takes about 20 seconds.
Lower Consumable Cost and Faster Payback
Compared with traditional cutting methods, this machine offers excellent consumable economy. The cost of the saw blade for each cylinder neck is only around RMB 0.03–0.04, while one saw blade can process approximately 6,000–10,000 bottle necks. This significantly reduces blade replacement frequency and overall operating cost.
With lower consumable expenses and higher productivity, the equipment helps manufacturers achieve a faster return on investment, especially in high-volume seamless gas cylinder production.
Stable Hydraulic Step Feeding System
The machine adopts a hydraulic step-by-step automatic feeding mechanism, providing stable transmission and high feeding efficiency. This structure is especially suitable for demanding industrial environments.
During feeding, the cylinder surface is protected from collision, scratches, or damage, ensuring better appearance quality and reducing the risk of rework.
Flexible Drilling Configuration
The equipment is equipped with a fast U-drill as standard, which can directly double drilling efficiency compared with conventional drilling methods. A twist drill can also be selected according to different workpiece requirements and processing conditions.
This flexible configuration allows the machine to adapt to multiple production processes and different cylinder specifications.
Space-Saving Integrated Design
Traditional production often requires one sawing machine and one separate drilling machine. This integrated system combines both processes into one compact machine, saving up to 50% of workshop space.
For cylinder manufacturers with limited production area, this design helps optimize factory layout and improve space utilization.
Reduced Labor Requirement
In a traditional split-machine layout, two operators are usually required to manage the sawing and drilling processes separately. With this integrated machine, only one operator is needed for operation and monitoring.
Over long-term production, this can greatly reduce labor costs while improving production management efficiency.
High Processing Accuracy and Smooth End Face
Compared with traditional sawing equipment, this machine produces a flatter and smoother cutting end face without obvious beveling. This improves the dimensional accuracy of the workpiece and ensures better consistency in subsequent cylinder processing.
The machine also features automatic axial detection, helping keep the sawn end face aligned with the neck ring position. This function further improves processing precision and finished product quality.
Advanced Mist Cooling System
The machine uses a professional atomized cooling system powered by 0.3–0.6 MPa compressed air. The cutting fluid is atomized into micron-level droplets and accurately sprayed onto the machining area. When the droplets contact the high-temperature cutting zone, they rapidly vaporize and absorb heat.
This quasi-dry cutting method combines cooling, lubrication, air blowing, and chip removal. Compared with traditional flood cooling, it consumes less cutting fluid, provides stronger cooling and lubrication performance, and prevents residual liquid from remaining inside the cylinder. The system is matched with special fully synthetic metalworking fluid HP-100.
