是當切割物體時，被切割物體板面溫度低，變形小且保持被切割物體原有材料特性的一種切割技術。尤其城市燃氣行業的管道冷切割技術，現如今已經到各大燃氣公司的普遍認同。切割時無火花，不管是鋼鐵管還是PE管，都不會因為切割時產生火花而發生爆炸事故。從而大大減少了施工時事故率，保證了人生安全。

現如今冷切割的方式有以下幾種：鋸切割、線切割、超高壓水切割、激光切割等。

萬澤錦達冷切割工具的優勢： 我們的風動切割機優勢：無火花冷切割。尺寸準確；切口平整，無裂紋、重皮、毛刺、凹凸、縮口、熔渣、氧化物、鐵屑等；快速省里。切口端面與管子軸心線要垂直，傾斜偏差Δ≤管子外徑的1%，且≤3mm。PE管無變形。經濟效益高，更便捷。

礦用風動切割鋸，又稱氣動切鐵鋸，礦用風動鋸軌機，礦用無火花切割鋸，礦用軌道鋼切割鋸，礦用U型鋼切割機，礦用管道切割鋸，手持式無火花切割機，小型防爆切割鋸等等，（根據其用法不同名稱也不盡相同）。

Product overview:
Pneumatic hand cutting saw is my company for high risk, safety factor particularly demanding work environment, such as chemical. Refinery. Natural gas mining. High risk wet underwater tunnel, and narrow space operations, especially in high gas coal mine explosion.
Shanxi million of new multi Zejin pneumatic mining machinery and equipment limited company independent research and development of hand-held cutting tools. It uses Taiwan imported pneumatic motor as power output, uses compressed air as power source, and does not use power. The pneumatic handheld cutting saw is not only light in weight, simple in operation and convenient to carry zero spark, but also to improve work efficiency. This product is safe and reliable. It is a pneumatic cutting tool in high risk industry.
Characteristic:
It is suitable for cutting all kinds of steel pipe, aluminum, copper, iron and other metal pipe rod. The cutting section is smooth and the precision is high.
The cooling cycle system makes the cutting surface of the workpiece accurate and accurate, without edge, and improves the service life of the saw blade, and is suitable for a long time sawing.
Product technical parameters:
Brand: up to Zejin million
Model: FDJ-120
Type: hand saw blade
Surface treatment: semi cast chromium plating
Full length: 1350mm
Width: 15mm
Tooth distance: 0.2mm
Thickness: 0.1mm
Sawing width: 1200mm
In order to work safely, we need to pay attention to the following points:
1, use the weight of the saw to control the cutting pressure. This weight is enough for softer materials. Too much pressure can reduce the speed of the saw blade. For harder materials, the speed of rotation of the saw blade can be reduced by pressure. The cutting is to keep the saws straight. Any twist or skew of the sawblade may reduce its service life
2. When the air motor is closed, the stem is released.
3. Before replacing the saw, be sure to disconnect the air hose and push the stem to release the pressure of Madane.
4, adjust the handle clockwise to release the tension on the sawing guide rod. Then release the lock of the side panel so as to open the side panel. Then remove the blade from the drive wheel and release it from the sawing guide rod.
5. The saw blade must remain moving before the next cutting begins. The saw blade can't contact any surface when a pneumatic saw.
6, understand the material needed to cut, if necessary to reduce the speed of rotation of the saw blade by reducing the pressure of the air.
7, ensure that the required cutting material is firmly fixed to prevent its movement.
8. When pneumatic air motor is operated, the stem is pressed with the finger, and then the cutting is started.
9. When the air hose is disconnected, the air hose valve is closed. Before disconnecting, open the air valve and decompress the hose.
