Indexable lathe tools

Advantages over Carbide brazed tools: 

① Avoid the disadvantage of cracks that tend to occur when brazing carbide; 

② Indexable inserts are suitable for depositing thin layers of harder materials (titanium carbide, titanium nitride, and alumina) on the surface of carbide inserts by vapor deposition to improve Cutting performance; 

③ Shorter tool change time; 

④ Because indexable inserts are standardized and centrally produced, the insert geometry parameters are easy to be consistent, and chip control is stable.. 

     Indexable tools have a wide range of applications, including a variety of turning tools, boring tools, milling cutters, external surface broaches, large-diameter deep hole drilling and nesting drills.

Indexable turning tools can be classified from several perspectives:

Classification by Machining Type

This is the most intuitive classification, directly corresponding to different turning operations.

• External Turning Tool: Used for machining external cylindrical surfaces or external faces. It is the most common type.

• Internal Turning Tool (Boring Bar/Tool): Used for machining internal holes. Sometimes, an external tool can be mounted at an angle to serve as a boring bar for large-diameter rough boring.

• Grooving and Cut-off Tool: Specifically designed for cutting grooves or ultimately parting off the workpiece.

• Threading Tool: Used for cutting internal and external threads.

Classification by Clamping Structure

This is the core classification, as it determines the clamping rigidity and positioning accuracy of the tool. Based on the insert clamping method, there are several typical structures:
