Roughing mill
Knife, said the performance can still be limited due to the shape of the workpiece, Nao processing of large die out when the need to use the cutting edge of the tool is usually longer. Lack of drive to win in a direction perpendicular to the cutting spindle, so it is easy to produce Zan flutter. Developed using a Japanese roughing end mills for processing with the new no chatter. And to improve the cutting conditions. In addition, the holes do not need pre-processing, which can shorten the processing time. Roughing cutter mold previously used for many species, have no center for the edge, cut processing times by the method of transportation. So. People cut the amount is limited to within the width of the blade to improve the processing efficiency is also limited in their own within a certain range. Introduction of such mills have 3 types: (1) with a center edge (4O ~ 63ram); (2) with a center hole (from 80 ~ llOmm): (3) flat head drill type (50 ~ 80ram) can choose according to usage, respectively. 1 with the types of mills can process fixed, C, center of the hole edge, without pre-processing-centering hole in the workpiece material can be processed directly on the cut. Therefore, reducing the phenomenon of chip biting mode even if the processing of negative, also no longer as before, the vertical mill for processing, as may enter into a short processing time. In addition, because starting from the inside of the processing, so even a thin wall thickness can also be a smooth process. The relative efficiency of its processing mill in the past (3O% ~ 5O%), it has now reached 90 or more. Non-processing time to achieve minimal efficient processing of ordinary milling tool diameter can be cut within the human processing. The disadvantage is the amount of processing per unit of time working with 77n; latch tunnel limit while the new mill can cut into the solid materials, processing. Allowing for a larger processing area in the from /, the outer mold for Qieru Jia hours of sun, the ordinary knife r. , J a. People cut the stroke is limited to the length of the blade cutting edge in self-』f,[link widoczny dla zalogowanych], Lai use of new mills, with the center of the blade, cutting people can get a longer stroke, thereby reducing the frequency and shorten the processing time of knife. In the form processing,[link widoczny dla zalogowanych], can be cone processing. Using traditional tools, when the cutter diameter 50ram, people cut the amount of lOmm, the processing efficiency of l2O ~ 150cm. / Inif1, while the use of new mills to obtain the processing efficiency can be achieved 300era. / Rain, is 2 times higher than traditional tools to achieve high efficiency. In addition, the central part of the cutter into the processing region in the force balance can be achieved, allowing for smooth processing. As a result of the chip within the oil processing method,[link widoczny dla zalogowanych], so you can smooth chip. 2 in which one 5 - hole cutter in the central part of the design of a non-cutting area. Therefore, to avoid cutting speed and there is a big difference between center section, it is also necessary to prevent a substantial increase in power, not to increase the machine useless load. Central part of the processing residues are processed in a continuous process out, will be left on the workpiece under the traces. 1,2 mill types used on the blade is to use a unique method of processing from forming, it implements the press can not be achieved by the shape. As the blade is longitudinally mounted, so stability is good, and can be cut into smaller chips, and can well chip. Is in front of chip resistance, can maintain a good sharpness, even a small power tools can also use these tools. No. 3 longitudinal end mills can not only carved mold processing,[link widoczny dla zalogowanych], but also carved horizontal mode processing. (One I compiled Hu Hao Cheng Machinery Co., Ltd.) 0 sponsored by the China Electronic Appliance Corporation of electronic products exhibition and the electronics industry exhibition will be in accordance with international practice in recent years, divided by product exhibition, such as consumer electronics Museum,[link widoczny dla zalogowanych], Museum of specialized equipment, pressure Transistor Museum, Museum of electrical tools, 2000 3 Instrument Museum, Museum relays, sensors Museum, Museum of electronic materials, electronic components, Museum, Museum and other military electronics. During the exhibition, will hold various academic exchange, technical seminars and product promotion will be 53 *
