Operating Instructions
- Firstly do the complete assembly of the Modular type / Flange type / Side Lock type / Face Mill Arbor type Duo Boring Bar. Post assembly (if required), measure the exact diameter on the pre-setter or by using a precise dial indicator..
- The boring head is initially set on minimum mark on the scale. (pic 1).
- In case you wish to adjust the diameter, loosen the Locking Screw of cartridges with the allen key provided and adjust the diameter using grub screws on the side of the tool. (pic 2).
- Use the scale marking to set the required diameter, adjust accordingly and then recheck if the required size is achieved.(pic 3).
- If the required diameter is achieved, tighten the locking screws of cartridges with a torque wrench (Recommended) for precise repeatability and to ensure sufficient torque for locking.(pic 2)
- The tool is now ready to use.
- It is recommended to dismantle the assembly and set to minimum after use, if to be stored for long period without use. Ensure periodic lubrication to avoid damage due to rusting.
- Ensure that the locking screw is loosened before using adjustment to avoid internal damage to adjustment mechanism.
