Description

Technical Field

[0001] The utility model relates to the technical field of round nose knives, in particular to a tungsten steel coated round nose knife with a shock absorbing effect. Background Art

[0002] Round nose cutter refers to a cutter whose arc length is greater than 1 / 4 circle. It is generally a mosaic structure. Each time the blade is replaced, the size of the cutter will change slightly. There is no static cutting edge. The wear of the blade is also small. The distance between the cutters can also be increased. However, due to the blind spot at the front end of the cutter, "top cutter" may occur in some narrow concave areas. In addition, the automatic corner clearing function of the current processing software is based on the ball cutter for detection. Even if you set the reference tool as a round nose cutter, the ball cutter of the same diameter is always used as a reference in the actual calculation process. If the automatic corner clearing is used directly in the subsequent processing, some concave areas will not be processed in place. However, the existing round nose cutter has some shortcomings, such as:

[0003] The round nose milling cutter of publication number: CN116900379A can achieve a smoother cutting action during the roughing process of the end edge, reduce the occurrence of chipping, and increase the durability of the round nose milling cutter during use. However, in actual use, since the round nose milling cutter has no support around it, it may cause slight vibration during processing, thereby reducing the accuracy of the device during use;

[0004] Therefore, we proposed a tungsten steel coated round nose knife with shock-absorbing effect to solve the above problems. Utility Model Content
