With the rapid development of high-speed machine tools, machining centers and machining technologies, the cutting speed and cutting power have increased sharply, resulting in a large increase in the amount of metal removal per unit time. The amount of cutting fluid used in machine tool processing is increasing, and the flow rate is sometimes as high as 80~. 100L/min. However, in high-speed cutting, it is difficult for the cutting fluid to reach the cutting zone, and the cutting fluid is difficult to cool. Therefore, the development of high-speed cutting technology has promoted the research of dry cutting technology.
In addition, in some special processing applications, such as the field of medical implants, a spherical joint is implanted into the hip, and the cutting fluid may stain the part or cause pollution. Therefore, the cutting fluid is absolutely not allowed in the special processing field. in use.
Dry cutting technology is a processing technology that does not use or use trace fluid in the process. It is a clean and environmentally friendly manufacturing process that controls the source of environmental pollution. As a new type of green manufacturing technology, it not only has low environmental pollution, but also saves the equipment related to cutting fluid, simplifies the production system, can greatly reduce the production cost of the product, and the chips formed by the time are clean and easy to be recycled. . Dry cutting has become a hot spot in the current research of green manufacturing technology, and has been successfully applied in actual processing.
Dry cutting must have strict performance requirements for the tool: the unique tool shape and targeted professional coating of the famous FRAISA high-speed tool brand represented by Dahai Precision Tool Co., Ltd., especially meet the requirements of dry cutting for tool performance. Has the following advantages:
1 has excellent thermosetting and wear resistance.
Dry cutting is usually performed at a much higher cutting temperature than during wet cutting, and the hot-hardened tool material can effectively withstand the high temperatures of the cutting process and maintain good wear resistance. The hardness of the tool material is more than 4 times that of the workpiece material.
2 lower friction coefficient.
Reducing the friction coefficient between the tool and the chip, the tool and the surface of the workpiece, to a certain extent, can replace the lubrication of the cutting fluid and suppress the increase of the cutting temperature.
3 high temperature toughness.
The cutting force during dry cutting is larger than that of wet cutting, and the cutting conditions for dry cutting are poor, so the tool has high high temperature toughness.
4 higher thermochemical stability.
At the high temperatures of dry cutting, the tool still maintains high chemical stability, reducing the catalysis of high temperatures on chemical reactions, thereby extending tool life.
5 has a reasonable tool structure and geometric angle.
Reasonable tool structure and geometric angle not only reduce cutting force, inhibit the formation of built-up edge, reduce cutting temperature, but also have the function of chip breaking and controlling chip flow. The shape of the tool ensures smooth chip evacuation and easy heat dissipation.
Summary Outlook Dry cutting technology is a major innovation in traditional production methods, and it is a new clean manufacturing technology. The increasingly stringent environmental regulations in the world are conducive to accelerating the promotion and application of dry cutting technology; the development of various superhard and high temperature tool materials and coating technology has created extremely favorable conditions for dry cutting technology; the minimum amount of lubrication devices are effectively applied. The introduction of standard small-hole machining tools has made more and more applications for the machining of various difficult-to-machine materials for quasi-dry cutting aluminum alloys. It is an emerging green manufacturing technology. It is of great significance to the implementation of the human sustainable development strategy, and the manufacturing technology of the new century.
