Today, the editor from Huilisheng will guide you on how to extend the lifespan of cutting tools:

1. Properly Control the Cutting Force and Cutting Speed of Diamond Cutting Blades**  

Properly managing the cutting force and speed of diamond cutting blades is an effective way to reduce the temperature in the machining area and extend the lifespan of the cutting fluid.

When machining difficult-to-process materials, finely sharpened blade edges are typically used, and both cutting depth and width should be kept moderate. 

The choice of cutting speed should consider factors such as material type, part structure, and machining equipment. 

Generally, for nickel-based alloys, the cutting speed should be controlled between 20 to 50 meters per minute;

 for titanium alloys, between 30 to 110 meters per minute; and for PH stainless steel, between 50 to 120 meters per minute.

2. Select Appropriate Cutting Methods for Diamond Cutting Blades

For difficult-to-process materials, different cutting methods can significantly impact the wear on cutting tools. 

Regardless of the method chosen, the principle remains the same: minimize cutting force and reduce the temperature in the cutting area. 

The trochoidal cutting method can significantly reduce the cutting area, minimizing the actual cutting contact angle and extending the cooling time for each tooth of the tool, 

thereby lowering the cutting temperature. The helical interpolation method ensures relatively even load distribution across each tooth, preventing excessive wear on a few teeth, 

with this effect being particularly noticeable at corners. Additionally, using a high-feed cutting method with shallow depths and large feeds effectively reduces cutting force,

 generating less heat and keeping the machining area temperature lower.

3. Ensure Timely and Effective Chip Breaking  

In metal machining, a significant amount of heat is generated in the chips. By controlling chip length and ensuring timely and effective chip breaking, 

this heat can be carried away by the chips, making chip breaking an effective method to control cutting temperature. When machining difficult-to-process materials,

 especially during roughing processes, chip breaking should be ensured throughout the operation, provided the rigidity of the machining system allows it. 

At the same time, a cutting fluid with good sedimentation properties should be used to settle and remove chips, preventing them from rubbing against the surface of the workpiece. 

When mixed with water, it forms a stable transparent solution. This product offers excellent sedimentation, lubrication, rust prevention, cooling, and cleaning properties. 

It also has strong resistance to microbial decomposition, maintains stability under varying water hardness conditions, and has a lifespan more than five times that of ordinary emulsified oils.
