Description

Technical Field

[0002] In the process of turning materials with good plasticity, long chips that are difficult to break will be produced. They may entangle the workpiece, tool and machine tool parts, thereby reducing the surface quality of the machined surface and damaging the tool and machine tool parts. At the same time, the chips tend to accumulate in the cutting area, and the heat generated during the cutting process is difficult to dissipate, thus generating high temperature at the tool tip and accelerating tool wear.

[0003] In the related art, chips are currently mainly broken by setting chip grooves, chip breaking blocks or chip breaking devices on the blade, but these chip breaking methods either have a narrow applicable range of cutting parameters or have a single function. At the same time, there is a mutually restrictive relationship between the positions of the chip breaking actuator and the cooling nozzle on the turning tool. In this way, in order to improve the chip breaking efficiency, it is easy to have a negative impact on the cooling effect. In another chip breaking method, there is a method of using high-pressure cooling cutting fluid alone for chip breaking and cooling, but this method requires a large amount of cutting fluid, and the cost of cutting fluid is high. At the same time, it increases the treatment of cutting waste fluid and generates more waste fluid that is easy to evaporate and harm the health of workers. At the same time, the integration of related auxiliary components in the above method is low, resulting in a complex structure and large volume of the entire device, which is not convenient for disassembly and maintenance. Based on this, there is an urgent need for a chip breaking device with high chip breaking efficiency and high cooling effect, and an integrated and adjustable chip breaking and cooling structure.
