Head of 5 axes linkage is placed or workbench is placed

Tigidity of machine tool main shaft compares a head to place a machine tool to be in the process of treatment, because main shaft swings, make the tigidity of main shaft differs; relatively and workbench places motive bed, because be workbench,swing, won't produce any effects to the tigidity of main shaft so. Graph 3 this spare partses need to be on face of two photographs adjacent machine two mutual and perpendicular via 2.

The efficiency that the machine tool machines is comparative what because rotate,nod is different, when point of a knife realizes same displacement, the main shaft that the head places a machine tool needs to swing older point of view () of similar lever principle, machine same part so, the efficiency that the head places a machine tool is lower. 3.

Cutting tool length swings to the influence of precision of machine tool treatment × of error = move about arm places horny correct to place a machine tool to tell, cutting tool length is the one part of move about arm. That is to say, below the condition that places in the head, the length of cutting tool affects length of move about arm, enlarge error. The error can grow along with the length of cutting tool and increase namely, if pursue,1 is shown. And like the graph 2 are shown, place motive bed to cradle type workbench, the length of cutting tool length and move about arm has nothing to do. The relation of the machining error that the head places machine tool and cradle type workbench to place motive bed and cutting tool length is in graph 4 with the graph 5 in can get be revealinged apparently. The concern that Nextpage graph places length of the cutting tool in the machine tool and position error 4 times pursues the concern that workbench of 5 cradles type places motive bed length and position error 4.

As swing, two kinds of machine tools can produce position error, but the head places a machine tool to still can produce appearance error, and workbench swings to won't produce appearance error head to place machine tool cutting tool to rotate, produce position error thereby. Meanwhile, the centre of turning circle of the feed direction that machines aperture and cutting tool produces deviate, the circumstance is shown 6 times like the graph, while so treatment aperture produces position error, still can produce appearance error, occurrence wedge aperture. The graph places a machine tool 6 times to be in generation position error while can produce appearance error and the position error that workbench places motive bed is swing by workbench cause, the whirl of the feed direction of main shaft and cutting tool center from beginning to end coincide, won't add again so generation appearance error. This is cradle type workbench swings to place the advantage with clearer than another photograph with the head. Graph workbench of 7 cradles type places motive bed not to produce appearance error 5.

5 axes machine what the comparison of size scope places machine tool main shaft as the head to swing, the size range of pipe bent of workpiece diameter direction will narrow, that is to say, main shaft swings the meeting when angle eats off the journey, the diametical limits that brings about 5 axes treatment to be able to process the greatest work thereby swings than the workbench that thirdly the axis adds man-hour small; and workbench places motive bed, to workpiece level directional dimension won't produce any effects, tell from this meaning, 5 axes treatment and the workpiece size scope when 3 axes are machined are identical. But the interference that the biggest range of workpiece of 5 axes treatment still needs to consider machine tool structure to cause. The user should ask machine tool supplier offers 5 axes to machine interference sketch map to analyse quite. Normally the circumstance falls, same route, use cradle type workbench to swing structural machine tool size range of pipe bent can compare 5 axes a machine tool that place type is bigger. The tigidity that the workbench of conclusion cradle type places motive bed main shaft is good, length of cutting tool of treatment efficiency tall; affects; treatment to won't produce the route with appearance error same; to machining precision to won't arise, machine tool size range of pipe bent can compare 5 axes a machine tool that place type is bigger. The tigidity that the head places machine tool main shaft is opposite poorer, machine efficiency to machine precision to be able to follow cutting tool length relative to inferior; grow and reduce; treatment to be able to produce main shaft of appearance error; to swing the meeting when angle eats off the journey, bring about what can machine thereby decrescent of measure of the greatest work. Need is additionally additional be, because need to overcome the consideration with self-prossessed workpiece,workbench places motive bed, if work is very serious, have taller requirement; to still have to clip, the machine tool when machining large and heavy-duty spare parts cannot realize workbench to swing, can use a means that place only.
