Fully Automatic High Pressure CNG Cylinder Fire Extinguisher CNC Screw Threading Machine, CNC Thread Rolling Machine Screw Thread Rolling Machine~
- Overview
The CNC lathe can realize X-Z two-axis linkage, equipped with Guangzhou CNC system, and has all the functions of NC machine tools, such as linear interpolation, arc interpolation, thread cutting, tool compensation, macro program, error compensation, constant linear speed, program storage and so on. The machine tool adopts integral casting with good overall rigidity, good dynamic performance, accurate motion precision control, stable machining precision and good consistency, and can be continuously controlled by two coordinates (longitudinal Z, transverse X). It can automatically complete the machining of inner and outer circular surface, conical surface, arc surface, end face and other rotary surfaces, as well as turning thread and other functions. The machine tool is suitable for the processing of accumulators, CNG gas cylinders and the mouth of industrial gas cylinders. It is a special CNC machine tool with good performance-to-price ratio.
- Applied application
- The machine is suitable for the processing of cylinder mouth, outer circle, inner hole, car sealing table, internal and external thread and so on, all of which are realized by NC programming, and the single station feeding and discharging device is adopted to realize (semi-automatic / manual 2 states optional). The clamping of the workpiece adopts the arc contact positioning between the front top bowl and the gas cylinder, and the rear positioning adopts the axial compression of the oil cylinder to clamp the workpiece between the two top bowls.

- Processing step
Step 1: Machine mouth, outer circle - done by the outer circle blade
Step 2: Machine the precision inner hole - done by the inner hole blade
Step 3: Machine thread - done by the outer thread blade
- Processing work-piece
- Cylinder diameter range: 232-406mm
- Cylinder length range: 895-1800mm (round bottom)
- Max. Cylinder weight: 500KG
- Processing time: 90-120 s/pc (based on PZ27.8 thread, without hole digging time)
- Thread quality and thread processing capability:
Thread processing shall not have defects such as missing teeth, cusps, flat teeth, double lines of teeth, and so on.
Thread roughness must be above Ra3.2 level
- Machine part introduction:
The machine bed is made of high-density cast iron HT250 with high strength and good shock absorption.
The larger chip discharge port design ensures the smooth cutting of the machine tool. The aging annealing provides a stable foundation for the high rigidity of the whole machine, and at the same time realizes the simplicity of chip removal and the reliability of protection. Low friction resistance, good rigidity, high resistance to vibration and deformation, so that users can obtain higher machining accuracy, faster moving speed and production efficiency.
- Flat & Rectangle guide rail: The flat machine bed made of high quality cast iron HT250 has been quenched with super audio frequency, which provides a stable foundation for the high rigidity of the whole machine, and realizes the simplicity of chip removal and the reliability of protection, as well as the full protection of the guide rail. The machine tool adopts rectangular guide rail in X and Z direction, and the width of Z direction guide rail is 70. The width of X direction guide rail is 60, Z direction 2 guide rail span 500MMX to 2 guideway span 280MM. The rectangular guideway has high positioning accuracy, good dynamic performance and good rigidity, which greatly improves the production efficiency and machining accuracy. Fast moving speed: Z axis: 10M/MIN X stroke: 10M/MIN
- Precision ball screw
The X.Z screw of this machine tool adopts 40 screw in diameter. The use of high-precision ball screw, with high-quality elastic coupling. Precision locking nut, so that the operation is stable and accurate, low noise, meet the requirements of high-precision machining
- Blade frame
The blade frame adopts the fixed clamp (4 pcs)
- Main shaft bearing and lubrication system:
The main shaft of this machine adopts precision domestic famous brand bearing with small clearance, high precision and high rigidity structure design. The spindle assembly is corrected by high precision dynamic balance, and the spindle has good rotation precision, high speed, low vibration and low noise. The use of the first international brand oil cooler for lubrication, so that the spindle bearing lubrication is fully in place. Keep the spindle temperature constant. (the system will alarm automatically when the oil pump of the oil cooler has no oil.) it is recommended that the buyer use No. 2 or No. 5 spindle oil. - Rotary plate for unloading the material:
After the processing is completed, the cylinder drives the flap to bring the workpiece into the assembly line (semi-automatic, manual), which is suitable for short gas cylinders and long gas cylinders. The carriage device can be adjusted up and down by manual worm gear (it can be fine-tuned up and down according to workpieces of different diameters), and it can also be manually adjusted back and forth to adapt to workpieces of different lengths. The total length is 600MM, 4 rollers, (the foot of the bed reduces a stiffener) | Item | Name | Manufacturer | Remark |
