Today, the editor from Huilisheng will guide you through the process improvements for tungsten carbide cutting blades:

1.Dynamic Balancing of Tungsten Carbide Blades

Dynamic balancing significantly enhances blade stability, as imbalance in tungsten carbide blades generates additional radial loads on the spindle system, 

with the load magnitude proportional to the square of the rotational speed.

2.Clamping Methods for Tungsten Carbide Blades

The clamping method for tungsten carbide blades cannot rely solely on general friction-based clamping. 

For blades with center holes, screw clamping methods or specially designed blade structures are recommended to prevent blade displacement during operation. 

The clamping force should align with the direction of centrifugal force. 

Pre-tightening force for screws must be precisely controlled to avoid premature failure due to overload. 

For small-diameter shank milling cutters, hydraulic chucks or thermal expansion chucks can achieve high-precision, high-rigidity clamping through controlled expansion and contraction.

3.Titanium Alloy as Blade Material

Using titanium alloy for cutting blades can effectively reduce cracking in tungsten carbide blades and improve cutting speeds. 

However, as titanium alloys are unsuitable for cold forging processes, they are not ideal for manufacturing tool bodies. 

Consequently, some high-speed milling cutters have begun adopting high-strength aluminum alloys for the tool body.

In the design of slitting circular blades, stress concentration should be minimized or avoided entirely.

 Grooves on the blade may induce stress, thereby reducing its overall strength. Therefore, sharp corners and deep grooves on the blade should be avoided as much as possible.
