Especially in long overhang machining (such as milling deep mold cavities), the traditional flat milling method (i.e. milling from one side of the workpiece to the other) has to reduce the cutting speed in order to minimize the lateral force that can cause chatter. ?? ??? ???? ??????? ????? ??? ???????? ?? ????? ???? ? ??? ??? ??????? ???????? ?? ????? ??? ??? ??? ????? ?????? ?? ??????? ?????? ????. ?? ???? ???? ?????????

He said, "During insertion milling, there is not much heat entering the workpiece because the cutting tool rotates at a fast speed to cut in and out the workpiece. Only a small portion of the workpiece with a moving step makes contact with the tool." This feature is particularly advantageous when cutting difficult to machine materials such as stainless steel, high-temperature alloys, and titanium alloys. ???????? ?? ??? ????? ????? ? ?????? ????? ????

【 Worth a try 】 Insertion milling can greatly accelerate the production rhythm of high-end and complex components. Gary Meyers, milling product manager at Seco Tool Company, stated that "the most commonly used areas of insert milling technology are mold manufacturing and aviation industry, as the types of parts in these industries are very suitable for insert milling." Mold manufacturers need to mill various complex shapes on the overall workpiece to form mold cavities, and many aviation parts are also processed from whole blanks. ?? ????

The design characteristics of milling cutters: Tool manufacturers have developed various milling cutters that can fully leverage the advantages of milling technology. Meyers from Shangao Tools said that the cutting force of such tools is basically directly transmitted back to the Z-axis. ??? ??????? ???? ?????? ????? ????? ???? ?? ??? 90 ??? ???? ?????? ????? ???. ????? ?? ????? ????? ????? ????? ?????? ?? ??????? ?? ??? ???? ??? ?? ???? ??? 87 ???? ?? ??? 90 ????. ??? ?? ???? ?? ???? ?????? ??????? ?????? ?? ????? ????? ?? ?? ????? ???? ??? ? ???? ???? ?? ???? ???? ?? ????? ?? ??? ????? ????? ???????. ??? ????? ???? ????? 87 ???? ????? ??? ???? ???? ? ????? ????? ??? ???? ????. ???? ?????? ???? ?? ???? ???? ????? ????? ??????? ??? ?? ?? ??? ???? ?? ???? ????? ??????? ???? ???? ????? ?? ????? ?? ???? ???? ???? ???? ????? ??? ? ????? ?? ???? ????? ??????? ????? ????? ??? ?? ????? ????? ?? ??? ????? ?????? ????? ?? ???? ?????? ?????? ?? ?????? ??????

"??? ??????? ???? ???? ????? ????? ???? ????? ???? extension of the milling blade cannot be too large." ????? ??? ?? ????? ?????? ?? ?????? ??? ?????? ???? ???????? ? ?????? ???? ????? ???? ? ???? ??? ????? ?????. He suggested that in order to achieve better machining surface smoothness, the radial cutting step should be reduced, which is the same as the reduced step machining method used in 3D precision milling with ball end mills. Meyers explained that fundamentally, the cutting step distance is determined based on the width of the blade and the amount of material cut into the workpiece by the cutting edge. ?????? ??? ??????? ???? ????????? ??????? ????? ???? ???????? ?? ????? ?????? ?? ??? ???????? ??? ?? ????????? ????? ??? ?????? ???????? ?? ????? ??????.

For example, the new features of the Kenner Z-axis milling cutter include: the serrated structure designed on the cutter body can improve chip formation and chip removal performance, and the design of the coolant outlet can improve the control of cutting heat and chip removal performance. ?? ????

Fiorenza pointed out that although the application of CAM milling technology has a history of at least 15 years, in recent years, machining workshops have become increasingly aware that milling can achieve higher material removal rates, and due to easier programming and verification of tool paths, the application of milling has become easier than in the past. ?????????

He said, "If a small concave cavity needs to be machined, using insert milling may be more suitable. Due to the short radial movement distance, there is no need to mill too much material radially. However, if the area to be milled is quite large, using high feed milling may be more efficient." High feed milling does indeed have lateral loads, but it can be minimized by using small cutting depth, fast feed, and multiple tool passes. Fiorenza of the company pointed out that using a milling cutter with a diameter of 50mm or more for long overhang milling may be very effective. ?????? ????? ???? ???? ??? ???? ??? ????? ?? ?????? ?? ?????? ??? ??? ????? ???? ????? ?? ????. ???: ???? ??? ????? ????? ????? ?? ???? ?? ?? ??? ????? ?? ?? ?? ???? ?? ?? ??? ????? ?? ?? ?????????? ???? ????????????????? ???? ???????. ????????? ?? ???????? ????? ??????? ???? ? ?? ???????? ????? ????????? ?? ???????? ????? ??????? ????? ? ?? ???????? ????? ????????? ?? ???????? ????? ?? 0.38-0.50mm ???? ????? ???? ?? ??? ??? ?????. ???? ??? ???? ?? ?? ??? ????????? ???????? ????? ?? ??? ???? ? ?????? ????????? ??????? ????.???? ?????? ?? ?????? ???? ???? ??????? ??????? ?????? ?? ??????? ?? ?????? ????????? ????? ????? ?? ???????? ?????? ???? ???? ?????? ??????? ????? ???. ??? ???? ?????? ???? ????? ?????? ? ?????? ????? ?????? ?????? ????? ????? ???? ?????? ????? ???? ?? ????? ?????? ?????????

When we enter the market in some parts of California, USA, which mainly cuts light materials, linear guide rail machine tools are on the right track. However, when we enter the market in the Midwest, which processes aviation materials and high-temperature alloys, users need hard rail machine tools that can withstand larger cutting forces and are more durable and durable. High speed mold processing machines using linear guide rails have excellent performance in quickly cutting small amounts of workpiece materials, and using insert milling technology can further improve their rough machining ability. But the ability of this type of machine tool to withstand chip load is not as good as that of hard rail machine tools. ??? ????? ??? ?? ???? ????????? ????? ????? ????? ????????? ?????????????? ????? ?? ????????? ????????? ????? ?????? ?? maximize ???? ? ??????? ???? ???????? ??? ?????
