Problems solved by technology

[0002] Machine tool processing is a process of processing blanks by cutting tools. When machine tools are processing metal profiles, especially electronic product shells such as: stainless steel, aluminum alloy materials and titanium alloy materials, due to the complexity of the cutting process, use The shell of a product processed by ordinary cutting tools generally requires several processes. Each curved surface with a large span or a large radian is composed of several small curved surfaces or even planes that are tangentially assembled and processed. Therefore, several knives are required to process the shape, such as To process arc segments with large radians or arc segments with special shapes, such a process often needs to be completed by multiple forming tools to complete two small arc segments and connect them into a complete arc segment. The process is complicated and inefficient, and low precision
Therefore the above-mentioned prior art cutting tool has obvious shortcomings for arc surface processing, and it is necessary to further improve it.

Embodiment 1

[0015] Embodiment 1: as figure 1 The curved surface forming knife shown includes a handle 1 and a cutting portion at the front end of the handle 1. The cutting portion is spherical, and the transition between the handle 1 and the cutting portion is in an arc structure to ensure the connection strength. The cutting portion is equipped with multiple Three evenly distributed helical cutting edges 2, between adjacent cutting edges 2 are spiral chip relief grooves, the three cutting edges 2 gather at the front end of the cutting part to form a tool tip, so that the tool can perform axial cutting, cutting edge 2 The thickness of the corresponding blade body increases from front to rear, and the blade body corresponding to the cutting edge 2 is a bevel that matches the helical direction of the chip edge 2, which facilitates the cutting process of the cutting edge 2, and the bevel promotes the cutting edge 2 to have a certain toughness , good strength, to avoid chipping, the cutting e...

Embodiment 2

[0016] Embodiment 2: refer to figure 1 The curved surface forming knife shown includes a handle 1 and a cutting portion at the front end of the handle 1. The cutting portion is spherical, and the transition between the handle 1 and the cutting portion is in an arc structure to ensure the connection strength. The cutting portion is equipped with multiple Four evenly distributed helical cutting edges 2, between adjacent cutting edges 2 are spiral chip relief grooves, the four cutting edges 2 gather at the front end of the cutting part to form a tool tip, so that the tool can perform axial cutting, cutting edge 2 The thickness of the corresponding blade body increases from front to rear, and the blade body corresponding to the cutting edge 2 is a bevel that matches the helical direction of the chip edge 2, which facilitates the cutting process of the cutting edge 2, and the bevel promotes the cutting edge 2 to have a certain toughness , good strength, to avoid chipping, the cutti...
