      ABH/DBH Twin Cutter Rough Boring Head Manuals

      ABH Rough Boring1
      Operating Instructions
      Adjustment starts one of twin cartridge on ABH/DBH boring head.
      Step 1: Unlock clamping screw anti-clockwise (see figure 5).
      Step 2: Loosen adjusting screw (See figure 3). Move cartridge to the required position according to the reference line marked on the tool body (see figure 4).
      Step 3: Fasten clamping screw properly (see figure 5).
      Follow the same steps aforementioned to adjust the other cartridge.

      ABH Rough Boring3
      Boring Options
      Two boring options available with ABH/DBH rough boring head.
      ① Balanced cutting: Cartridge A on side A, while cartridge B on side B. For stable cutting with a small stock allowance. (See figure A)
      ② Stepped cutting: Cartridge A on side B and cartridge B on side A. For cutting with a big stock allowance. (See figure B)
      4. Notices Of The User
      Make sure the cutting data for the two cartridges are same when stepped cutting is adopted.
      Frequently Asked Questions
      Q What is the boring range covered by the ABH/DBH Rough Boring Tool series?
      The ABH/DBH Rough Boring Tool series covers a wide boring range from 20mm up to 204mm. Different adapter sizes (DCK1 through DCK7) are available to match the required boring diameter, ensuring flexibility for various machining applications.
      Q What is the difference between the DBH standard boring tool and the DBH 6º Rough Boring Tool?
      The DBH 6º Rough Boring Tool features a 6-degree angled cartridge design (using SPMT/SCMT inserts) compared to the standard DBH tool (which uses CCMT inserts). The 6º angle provides different cutting geometry suited for specific rough boring conditions and material requirements.
      Q What inserts are compatible with the DBH Rough Boring Tool cartridges?
      The standard DBH cartridges are compatible with CCMT series inserts (CCMT0602, CCMT09T3, CCMT1204) depending on the boring range. The DBH 6º cartridges use SPMT060204 and SCMT series inserts. The FM-DBH large diameter tools also support CCMT1204 and CNMG1606 inserts, and are compatible with DEREK, KYOCERA, or SUMITOMO brand inserts.
      Q What adapter interfaces are available for the FM-DBH Large Diameter Rough Boring Tools?
      The FM-DBH Large Diameter Rough Boring Tools (FMS and FMX series) support multiple adapter interface options including HSK-A, BT, SK, BBT, and CAT type connections, making them compatible with a wide range of CNC machining centers.
      Q What are the two boring cutting options for the ABH/DBH Twin Cutter Rough Boring Head?
      There are two available cutting options: (1) Balanced cutting — Cartridge A is placed on side A and Cartridge B on side B, suitable for stable cutting with a small stock allowance. (2) Stepped cutting — Cartridge A is placed on side B and Cartridge B on side A, suitable for cutting with a larger stock allowance. When using stepped cutting, ensure the cutting data for both cartridges is identical.
      Q What are the key features of the FM-DBH Large Diameter Rough Boring Tool?
      The FM-DBH Large Diameter Rough Boring Tool is designed with 70–90% aluminum construction for lightweight performance, features internal cooling supply for efficient heat dissipation, provides axial direction adjustment of 0~1.5mm for precise setup, and is dynamically balanced at G6.3 at 1,000 rpm for smooth high-speed operation.
