Description

Two-wheel cutting tool structure

The present invention relates to a double-wheel cutting tool structure, and particularly to a double-wheel cutting tool structure with a water jet mechanism.

General lathe processing technology uses various turning tools to cut various processed objects. During the cutting process, due to constant contact and friction between the tool and the workpiece, the cutting area is prone to high heat. If the temperature is not properly cooled, it will easily cause damage to both the tool and the workpiece, which will reduce the yield and increase the tool’s Damage rate. Therefore, coolant must be used from time to time during the cutting process to cool and remove debris.

At present, the industry has a turning tool structure that can be filled with coolant. The pump on the lathe can also be directly used to spray the coolant to the cutting place through the turning tool structure with a spray mechanism. The coolant is used to cool the cutting part of the tool and take away the cutting Debris produced. However, because each lathe is equipped with different pumps, the force that pressurizes the coolant is also different, but the coolant outlet position on the turning tool structure is fixed, or when the tools used are different, All will make it impossible to spray the coolant accurately to the cutting part of the tool when the turning tool structure with spraying mechanism is used on different lathes. In other words, when the pump pressure is high, the coolant may be sprayed beyond the cutting part of the tool; conversely, if the pump pressure is low, the coolant may not be sprayed to the cutting part of the tool. Or, at the same pressure Under pressure, if the tool used is larger, the coolant may reach the cutting area of the tool; on the contrary, if the tool is small, the coolant may spray beyond the cutting area of the tool. In all the above situations, it is easy to fail to spray the coolant accurately to the cutting part of the tool, not only the cooling effect is not good, but also more coolant may be required, resulting in increased costs. What's more, during extremely high-speed machining and cutting, some of the processed materials encountering moisture contained in the coolant may cause changes in the cutting surface, and the coolant cannot be used for cooling.

Therefore, one aspect of the present invention is to provide a two-wheel cutting tool with a water jet mechanism. Install the nozzle screw on the two-wheel cutting tool, and turn the nozzle of the nozzle screw toward the tool of the two-wheel cutting tool. Use the nozzle screw to screw in or out to adjust the position or angle of the nozzle on the nozzle screw. With different tools, the sprayed coolant or cooling gas can be accurately sprayed to the tools to achieve better cooling and chip cleaning effects.
