Internal Turning Tool Holder
Internal turning tool holders are special tools for lathe internal hole processing, with the following product advantages:
1. Improved processing accuracy: The precision design of the internal turning tool holder can ensure high precision during the processing, thereby improving the quality and dimensional consistency of the processed parts.
2. Enhanced stability: The high rigidity design of the tool holder helps to reduce vibration during processing and improve the stability of processing, especially during high-speed processing.
3. Quick tool change: Some internal turning tool holders are designed with a quick tool change system, which can shorten the tool change time and improve production efficiency.
4. Modular design: The modular design allows users to quickly change blades or tools according to different processing requirements, which improves the flexibility and adaptability of processing.
5. Durability: High-quality materials and precise manufacturing processes make the internal turning tool holder have a long service life, reducing the frequency of replacement and maintenance costs.
These advantages of the internal turning tool holder make it an indispensable tool in precision processing and mass production.
The parameters of the internal turning tool holder mainly include:
1. Tool bar diameter (d): This is the basic size of the tool holder. Common ones are A=32mm, B=40mm, C=50mm, D=60mm, E=70mm, F=80mm, G=90mm, H=100mm, J=110mm, K=125mm, L=140mm, M=150mm, N=160mm, P=170mm, Q=180mm, R=200mm, S=250mm, T=300mm, etc.
2. Tool length: The length of the tool determines the hole depth that the tool holder can process. The length is usually represented by a specific code, such as A=32mm,
B=40mm, C=50mm, etc.
3. Main rake angle: affects the cutting method and chip removal direction. Common angles include 0º, 5º, 13º, 15º, 7º, 11º, etc.
4. Blade back angle: affects the sharpness of cutting and chip removal effect. Common back angles include 7º, 11º, 2.5º, 5º, etc.
5. Tool bar material: can be steel or carbide, some also have internal cooling function to improve cooling effect and tool life.
Internal turning tool holders have a wide range of applications, mainly including the following fields:
1. Automobile manufacturing: used to process key components such as engine parts, shafts, discs and cylinder blocks, which have high requirements for precision and finish.
2. Medical device manufacturing: In the field of medical devices, internal turning tool holders are used to process precise internal holes, such as computer tomography housing workpieces.
3. Aerospace: In the field of aerospace, internal turning tool holders are used to process difficult-to-process materials such as titanium alloys, such as aircraft engine connectors and fasteners.
