Hole machining
AFB Series Fine Boring Head Operator's Manual
Preparation. 1. Verify that the adjustment range of the fine boring head meets the requirement of the bore diameter to be machined. 2. Check ( right figure ) that all parts are in order; that the cartridge and insert locking screws are locked tight. 3. Clean and wipe the shank mounting hole and tighten the boring head mounting screw on the shank. 4. Confirm that the assembled boring tool meets the requirement of boring diameter and machining depth. Step 1: Loosen the fine adjustment cartridge locking screw ⑦ on the tool change chuck or tool setting gauge. Step 2: Rotate the fine adjustment dial ③ to preset to the size needed as indicated . Step 3: When preset to the size needed, please make the fine adjustment in the same direction to ensure the fine adjustment accuracy. Step 4: Tighten the fine adjustment cartridge locking screw ⑦ with proper force to complete the adjustment.

1. Before machining, make sure all parts are locked properly to avoid damage to the boring head during machining. 2. The AFB series fine boring head rotated its internal precision screw to achieve radial movement of the cartridge. In case of excessive resistance or unable to turn the adjustment dial, stop the operation and check immediately (whether the adjustment cartridge screw is loose or it is out of the adjustment range of the boring head diameter). 3. For reverse boring, use the right-hand insert and reverse rotate the machine spindle, paying attention to the interference range during the movement. 4. For long overhang (> 4 x coupling diameter), it is recommended to use anti-vibration boring tools. 5. Large insert nose radius will help to improve machining safety and surface quality, but may generate vibration. An insert nose radius bigger than 0.4 mm should not be used for finish boring.
ARB Series Rough Boring Head Operator's Manual
Rough boring head main parts name
Preparation. 1. Verify that the adjustment range of the rough boring head meets the requirement of the bore diameter to be machined. 2. Check (as shown on the right) that all parts are in order; and the cartridge, radial adjustment screw, and insert locking screw are locked to prevent damage to the tool or to avoid cartridge flying out during machining and causing accidents. 3. Confirm that the assembled boring tool meets the requirement for boring diameter and machining depth. 4. Pay attention to the chip removal, cooling, cutting depth and other conditions, and pay attention to the impact of chips to the vibration control. Step 1: On the tool change chuck or tool setting gauge, loosen the cartridge screw ⑥ . Step 2: Turn the radial adjustment screw ⑦ to reach the required size of the tool. Step 3: After adjusting to the size of the tool, lock the cartridge screw ⑥ to complete the adjustment.
Attention
1. Before machining, ensure that all parts are properly locked to avoid damage to the boring head or prevent the cartridge flying out during machining, which may cause accidents. 2. ARB series rough boring heads are designed for equal radius and balanced machining with double edge cutting; they are used for rough boring with tolerances greater than or equal to IT9 when metal removal rate is a priority. 3. For rough boring with large depth of cut, adequate chip space and chip evacuation condition must be ensured to reduce tool vibration caused by chip jam. 4. For long overhang (> 4 x coupling diameter), it is recommended to use anti-vibration boring tools. 5. A large insert nose radius will help to improve machining safety and surface quality, but may generate vibration. The recommended starting tip nose radius is 0.8 mm.
