The internal turning tool holder is a positioning device used for internal hole machining on a lathe. Its features and structure are as follows:

1. Function: The boring tool holder is used to fix and locate the boring tool, ensuring accuracy and stability during the boring process.

2. Structure: Usually consists of a base, a clamping mechanism, and an adjusting device. The clamping mechanism is used to hold the lathe and achieve precise positioning, while the adjusting device is used to adjust the position of the lathe tool.

3. Material: The locating seat of the internal turning tool is usually made of high-strength alloy steel or cast iron to ensure sufficient rigidity and wear. Position.

4. Adjustment method: The precise positioning of the internal turning tool can be achieved by screw adjustment, hydraulic adjustment, etc.

5. Applicability: The boring tool holder has a large adjustment range, suitable for machining internal holes of different diameters and depths.
   

Scope of application:

1. Precision machining: The boring tool holder is widely used in the machining of precision internal holes, such as bearing holes, bushing holes, and cylinder.

2. Auto parts: In the field of automobile manufacturing, the boring tool locator is used to process internal components such as engine blocks and cylinder liners.

3. Mould manufacturing: In the mould manufacturing industry, the internal hole turning tool positioning seat can be used to process the internal holes of plastic moulds die-casting moulds, etc.
   

4. Medical instruments: In the field of medical instrument manufacturing, the internal turning tool holder can be used to process precision internal components such as orthopedic and artificial joints.
