    BBT Angle Head DG90 Series - Adjustable Tool for Efficient Machining | China Suppliers & Factory

    ,

    Introducing our high-quality cutting tool designed for precision machining. This innovative tool rotates in reverse to the machine spindle, ensuring enhanced performance and efficiency. Included with the tool are a wrench and nut; however, please note that the collet must be ordered separately. One of the key features of this product is the adjustable angles of the Locating Pin to the drive key groove and cutting edge direction, allowing for customized setups to meet diverse manufacturing needs. For optimal installation on machines, a Stop Block is required and should be ordered separately. Our design also facilitates effective cooling, enabling cooling liquid to reach the cutting edge directly from the tool body when utilized with the Stop Block. Please be aware that auto tool change may not be available for all machine models. As a trusted China supplier and factory, we are committed to providing top-notch products that meet the rigorous demands of the machining industry.

      • When ordering, provide us with the manufacturer, model and specifications of the machine tool, as well as the BIG product model number.
      • Kindly inquire us regarding Stop Block and mounting dimensions.
      • Kindly check with the machine tool manufacturer for the shape of the Stop Block, as it will vary for each machine tool model.
      • The dimension from the spindle gauge line to the top of the Stop Block (※) is our standard length.
      ▲ As the Air Turbine requires clean air, do not share the same Stop Block with other products.
      Frequently Asked Questions
      What is the difference between Standard and Powerful versions of BBT Angle Heads?
      The Powerful version features a reinforced internal structure for higher torque and rigidity, making it suitable for more demanding cutting operations. The Standard version is designed for general-purpose machining. Both share the same external dimensions, but the Powerful version typically has a slightly higher weight.
      Is a Stop Block required for all BBT Angle Head models?
      Yes. A Stop Block is required when mounting any BBT Angle Head on a machine. The Stop Block prevents the angle head body from rotating during operation. Please order it separately and confirm the correct model with your machine tool manufacturer, as the shape varies by machine model.
      Can coolant be supplied through the BBT Angle Head to the cutting edge?
      Yes. Cooling liquid can reach the cutting edge through the tool body when used with a compatible Stop Block. For the ODG90 Oil Hole Type, coolant must be supplied continuously — never run the unit without coolant. For some models, the cooling tube should be connected at PT1/8 as shown in the product diagram.
      Are collets included with BBT Angle Head products?
      For most models, the wrench and nut are included, but collets must be ordered separately. Please specify the required collet size (ER11, ER16, ER20, ER32, etc.) when placing your order. For tapping types, neither the collet nor the tap chuck is included.
      Is automatic tool change (ATC) supported with BBT Angle Heads?
      Automatic tool change may not be available on all machine models. Compatibility depends on the specific machine tool and its ATC mechanism. We recommend confirming ATC compatibility with your machine tool manufacturer before use.
      What is the drive ratio of the BBT Angle Head DG90 Series?
      Most BBT Angle Head DG90 Series models operate at a 1:1 drive ratio, meaning the output spindle rotates at the same speed as the machine spindle. Tapping type models (TC12, TC20) use a 2:1 deceleration ratio, reducing the tap speed to half the machine spindle speed. Some special models offer acceleration or deceleration ratios for specific applications.
