Gantry milling spindle linkage more power head 2018 - advantage analysis 07 - 03 Li Shenwang Liu Chunxiang Guo Junhong ( Tangshan college) Abstract: longmen milling spindle linkage power head more planetary gear structure was adopted to realize the composite cutting motion, with the knife dish at low speed can achieve high speed cutting, cutting force is small, long service life and high efficiency of cutting tool edge, particularly suitable for difficult-to-machine materials and super large parts especially large thin wall parts machining. Key words: multiple spindle linkage; High speed cutting; Cutting force; 0 the knives' service life. The introduction of industrial manufacturing is the important pillar of the national economy, upgrade is to realize the development of the city, is the leading industry of national economy and strategic industries, its development level is the measure of a country and area scientific and technological progress and the important symbol of comprehensive competitiveness, manufacturing industry is the rise and fall of confirm the rise and fall of great powers, without a strong manufacturing is unlikely to become a economic power. According to the modern mechanical processing high speed high efficiency, high precision and high flexibility, composite, intelligent and green development general trend, research and development new high-end processing equipment is an important subject in the field of machining, has important theoretical and practical significance. 1. Gantry milling spindle linkage more power head is shown in figure 1, the main motor, gear Z1, Z2 respectively a pair of gear, shaft, the knife dish ( Line frame) Z3 and Z4 of, speed regulating motor, gear, respectively, a pair of spiral bevel gear, the center of the wheel and the planetary wheel, endmill, housing and ancillary support of components called 'gantry milling spindle linkage power head more', 'gantry milling spindle linkage power head more knife plate ( Line frame) Due to the low rotational speed, thus can be in the knife dish ( Line frame) Between casing and adding auxiliary support to improve the knife dish ( Line frame) The stiffness and the rotation accuracy. 'more than gantry milling spindle linkage power head can be installed directly on the gantry milling machine as shown in figure 2, figure 2 called' multiple spindle linkage milling equipment. 2. Gantry milling spindle linkage power head more advantage analysis owing to the cutting is a spiral cutting edge at the bottom of the spiral blade end mill finish and edge cut into the workpiece rotation edge, so the straight blade cut into the workpiece directly and effectively reduce the cutting force, reducing cutting heat, at the same time eight root endmill discontinuous helical blade cutting workpiece that each spiral blade end mill has cutting the workpiece in machining process and not cutting workpiece time, this is good for heat dissipation, which is much gantry milling spindle linkage power head both reduces the cutting force, and reduces the cutting heat, cooling effect and good at the same time. Gantry milling spindle linkage milling power head more actual cutting speed is the speed of the spiral blade end mill with the speed of the knife dish of synthesis, so when the speed of the spiral blade end mill take a larger value, the speed of cutter head in a smaller value can realize high speed cutting, milling spindle linkage of power head more namely cutter head under the low speed can achieve high speed cutting, it can effectively solve the high speed cutting field dynamic balancing and reliability of the large cutter disc problem. Gantry milling spindle linkage more average power head will always wear the different spiral blade different on the cutting edge of end milling cutter, thereby increasing the service life of the cutting tool, this from the method to solve the difficult processing materials processing in the problem of short tool life. Gantry milling spindle linkage more power head can increase the number of helical blade end mill and improve the speed of the spiral blade end mill to improve processing efficiency and the material removal rate, so it is of high efficiency and high material removal rate. Above all, gantry milling spindle linkage power head with the knife dish at low speed can achieve high speed cutting, small cutting force, cutting tool of long life and high efficiency and high material removal rate etc advantages, particularly suited to hard-cutting materials and super large parts especially large thin wall parts machining. Conclusion gantry milling spindle linkage more power head adopts planetary gear structure to achieve the composite cutting motion, with the knife dish at low speed can achieve high speed cutting, cutting force is small, long service life and high efficiency of cutting tool edge, particularly suitable for difficult-to-machine materials and super large parts especially large thin wall parts machining.
