For aluminum alloy parts with large processing allowance, in order to create better heat dissipation conditions and reduce thermal deformation, heat concentration must be avoided as far as possible. The method can be adopted is symmetrical processing. For example, there is a 90 mm thick aluminum alloy plate, it needs to be milling to 60 mm thick, if the milling side immediately turned over to milling the other side, because each face is a processing to the end of the size, continuous processing allowance is large, it will cause the problem of heat concentration, so that the milling good aluminum alloy plate flatness can only reach 5 mm. If the symmetrical machining method of repeated cutting on both sides is adopted, each surface is processed at least twice until the final size is reached, which is conducive to heat dissipation and the flatness can be controlled at 0.3mm.
CNC machining tool concept
Tool is used for machining tools in machinery manufacturing, also known as aluminum alloy tool. Generalized cutting tools include both cutting tools and abrasive tools. Most knives are for machine use, but some are for hand use. Since the tools used in machinery are basically used to cut metal materials, the term "tool" is generally understood to mean metal cutting tools. The cutting tools used to cut wood are called woodworking tools.
The history of the tool
The development of cutlery plays an important role in the history of human progress. In China as early as 28 BC to the 20th century, there were brass cones, copper cones, drills, knives and other copper cutting tools. In the late Warring States period (AD century), the carburizing technology was mastered and copper cutting tools were made. The drills and saws of that time bear some resemblance to modern flat drills and saws. However, the rapid development of cutters came in the late 18th century with the development of machines such as the steam engine.
Cutting tool classification, cutting tool according to the form of workpiece processing surface can be divided into five categories.
Machining a variety of external surface tools, including turning tools, planer, milling cutter, outer surface broach and file, etc.
Hole machining tools, including drill, reaming drill, boring cutter, milling cutter and inner surface broach, etc.
Thread processing tools, including taps, die, automatic thread cutting head, thread turning tool and thread milling cutter, etc.
Gear machining tool, including hob, gear shaper, shaving cutter, bevel gear machining tool, etc.
Cutting tools, including inlaid circular saw, band saw, bow saw, cutting cutter and saw milling cutter, etc.In addition, there are combination cutting tools.
