What Technical Improvements Are Needed For Cutting Circular Blades

1、 The dynamic balance of the slitting circular blade is of great help in improving the safety of the blade, as the imbalance of the circular blade generates an additional radial load on the spindle system, which is proportional to the square of the rotational speed
2、 The clamping method of circular blades does not allow the use of general friction clamping. Instead, blades with central holes, screw clamping methods, or specially designed circular blade structures should be used to avoid blade flying. The clamping force direction of the blade seat and blade should preferably be in the same direction as the centrifugal force. The pre tightening force of the screw should be controlled together to avoid early damage to the screw due to overload. For small diameter milling cutters with handles, Hydraulic chucks or thermal expansion and contraction chucks can be used to achieve high-precision and high stiffness clamping
3、 As a cutting tool material, titanium alloy can effectively reduce the fracture of circular blades and increase their ultimate speed. However, due to titanium alloy being less sensitive to cuts, it is not suitable for manufacturing tool bodies. Therefore, some high-speed milling cutters have begun to use high-strength aluminum alloy to manufacture tool bodies
4、 In terms of the construction of the cutting circular knife, it is necessary to avoid and reduce stress concentration as much as possible. The groove on the blade can cause stress to decrease the strength of the blade, so it is advisable to avoid sharp corners at the bottom of the groove and through the groove
