Graduation

Trigger

Pneumatic motor mounted on torque wrench, for work from provisional tightening to final tightening using just the one tool.

ACLS100N3 [Overall length: 333.5mm]

AC50N3 [Overall length: 293mm]

Left: Turning with an ordinary socket　　　　　　　　　　　　　　　　Right: Turning with an anti-vibration socket

The ACQSPFD3, which is able to transmit tightening torque data wirelessly, can be custom modified upon order. Please contact Tohnichi for details.

Application

For assembly and mass-production.

Features

The AC3 series semi-automatic Airtork can be used with anti-vibration sockets for impact wrenches. This reduces vibrations during turning, and improves work efficiency.
A3 series high provisional tightening torque type
Regular tightening tasks using an impact wrench plus a torque wrench become part of a single process, greatly improving task efficiency.
Provisional tightening is applied using the air motor operation, and completed in high accuracy by manual torque wrench operation.
Final tightening is done with the torque wrench, so fluctuations in air pressure will not affect applied tightening torque.
Changing tightening torque is simple: just turn the knob to adjust the N•m scale.
Easy calibration with torque wrench tester
LS version comes with limit switch. Thich creates error-proofing (Pokayoke) system when used with CNA-4mk3 count checker (sold separately).
Except for some products, the AC3/ACLS3 series are compliant with ISO 6789:2017 starting January 2022. For more information, see the technical data “Initiatives for ISO 6789:2017” at the bottom of the screen.
