Cold Cutting Saw

Product Description


CNC Cold Cutting Saw is to cut the pipe into specified length while it is traveling.


   Our PATENT I: After changing or sharpening saw blade, no need to adjust pipe and saw blade position, customers just push the button on console, all of actions can be done automatically. It is faster and more precise. 

Cold Cutting Saw

   Our PATENT II: 3 Saw clamps(Jaws), we invented 3 saw clamps, in order to avoid the following problems: When pipe diameter is bigger than 76mm, saw blade stroke is long after cutting, and cutting gap is very small, it may not loose saw blade, then servo alarms and stop, saw blade may be broken after saw car moving back.

Cold Cutting Saw

   Our PATENT III: Aogang anti-collision mechanism is made up of rubber bumper and anti-rebound unit. When the saw car failed accidentally, the pinion are off the rack and saw car will hit the rubber bumper block. At the same time, the hook on the saw car just catches the anti-bounce pin, the anti-collision block and the anti-bolt pin work together, saw car will stop at the offside momentarily, avoiding the pinion damage caused by the violent impact of the rebound pinion and the rack.

   In order to meet different customers’ requirement, Aogang engineers researched and developed 2 control systems : 

1)       Siemens-SIMOTION System: it is specially for high speed motion controller, compose of  Simotion D4x5 center controller, S120 Servo Driver, 1FK(T)7 Synchronous permanent magnet machine, ProfiNet Industry Ethernet, and so on. 

2)       Aogang System

   Based on rich experience, TOP high performance ARM Chips are used, dominant frequency reach upto 100MHz. Pipe length and pipe mill running speed can be the most correct calculated.

   High Quality Speed Measurement Encoder: Aogang uses high quality waterproof and dustproof type encoder from Japan, which can bear external force of 5Kg(radial direction) and 3Kg(shaft direction) individually. After collecting information from our customers, failure rate is lower than 2% during production, reducing pipe mill down time.
