The Fundamental Difference Between Torque Air Wrench And Air Wrench

First of all, pneumatic is the driving medium. Torque Air Wrench can adjust the torque, but the pneumatic wrench cannot adjust the torque. The accuracy of the general pneumatic torque wrench can reach within 5%, and the adjustable torque range is large. Now the maximum torque can reach 12000 Nm, and pneumatic wrenches are mainly impact wrenches, with torque but usually small torque, and the torque is not accurate, the noise is higher, compared with the pneumatic torque wrench, the price is higher, generally imported things, the price of the pneumatic wrench is lower.

Torque Air Wrench and Air Wrench, one with torque and the other without torque, the pneumatic wrench with torque can control the torque and tighten the bolts accurately.

Pneumatically, it can only impact bolts hard, and it is impossible to control the bolts to be tightened as required. The pneumatic torque wrench you mentioned should refer to the pneumatic ratchet wrench, which has no torque correction function. The torque wrench generally uses the specified torque to lock the screw, and the torque can be adjusted. The pneumatic torque wrench uses compressed air as the power source. The ordinary one is manual. If you only pay attention to the depth of the screw, or if you Said, what you want to control is height.

To be honest, no matter what brand, pneumatic tools are difficult to do. Unless you lower the air source, rely on the naked eye to control the number of rotations, and then calculate the thread stroke. This is difficult to achieve if it is actually operated.

Therefore, I personally recommend power tools with sensors. The depth of screw tightening is controlled by the angle setting. And when the angle is reached, the tool stops, which is feasible. Pneumatic tools are mainly used for low-precision applications. Power tools are required for some complex and high-precision applications. Such as car tires, engine cylinder heads, etc.
