The suitable shank needs to be ordered separately (see P201/P210)
If there is a problem of overweight quality during machining and weight reduction is required,
the letter \"A\" can be added after the series name, and a bridge-type boring tool with an
aluminum alloy tool bridge can be selected.
For example: The Order No. GBR-LRBD730-850C40 indicates a bridge-type boring tool with a
common steel tool bridge.
The Order No. GBR-LRBAD730-850C40 indicates a bridge-type boring tool with

7. Rough Adjustment Scale Line
Adjustment steps:
1. Loosen the 6# tool apron locking screw.
2. Roughly adjust the two tool aprons to be symmetrical according to the scale line. The size of the two tool tips should
be about 0.5mm smaller than the size to be machined.
3. Tighten the 6# tool apron locking screw to lock the tool apron. Turn the 2# adjusting screw and press it tightly against
the 6# tool apron locking screw to prevent tool deflection.
4. Conduct a trial boring, measure the size of the machined hole, compare it with the required size, and calculate the
smaller value.
5. Slightly loosen the 6# locking screw so that the 2# adjusting screw can push the tool apron to move.
6. Press the 2# adjusting screw tightly and compare it with a dial indicator to make the movement amount reach the
calculated smaller value.
7. Press the 6# locking screw tightly and machine the workpiece to the required size.

6. Oil Nozzle
7. Dial
Adjustment steps:
1. Align the slot of the 1# fine boring tool apron in the correct direction and snap it into the boring head. First, lock the
3# locking screw, and then lock the 2# tool bit locking screw.
2. Rotate counterclockwise to loosen the 3# locking screw. Use an Allen key to turn the dial to adjust the tip seat to the
required position for the cutting diameter. Then, rotate the 3# locking screw clockwise to lock the tool. Each grid rotation
of the dial represents a diameter change of 0.01mm (clockwise rotation-increase, counterclockwise rotation-decrease).
3. Check the marking on the tool for the boring range of the tool bit. (Do not rotate the dial beyond the range.)
4. Conduct regular maintenance and inject lubricating oil (inject from the 6# oil nozzle).
5. Do not disassemble the parts sealed with red paint, otherwise, the accuracy of the boring head will be damaged.
6. When performing back boring machining, the rotation direction of the tool must be reversed.

1. Loosen the 4# slider locking screw.
2. Roughly adjust the 5# slider and the 7# tool apron according to the scale line. The size of the tool tip should be about
0.5mm smaller than the size to be machined. [Note: Ensure the rough adjustment size by comprehensively adjusting the
positions of the 5# slider and the 7# tool apron and the position of the 4# slider locking screw.]
3. Tighten the 4# slider locking screw and the 8# tool apron locking screw. Turn the 6# tool apron adjusting screw and
press it tightly against the shank of the 8# locking screw to prevent tool deflection.
4. Conduct a trial boring, measure the size of the machined hole, compare it with the required size, and calculate the
smaller value.
5. Slightly loosen the 8# tool apron locking screw so that the 6# tool apron adjusting screw can push the 7# tool apron to
move.
6. Use a wrench to turn the 6# tool apron adjusting screw and compare it with a dial indicator to make the movement
