Orgnaization of silk of part of numerical control device, machine tool, carry, , filar wearing, , procrastinate board (direction of X, Y) in the computer control falls, make shape harmoniously motion, lathe bed (secure system of each machinery, transmission) composition; High frequency strong power source, action has 2 (offer time cutty pulse to discharge) , (of working fluid system.
Insulation action; Discharge bits and cooling action) . Processing technique of cut of numerical control line is to should use the program that has written, rely on electrode silk discharge to come cut all sorts of little work, the work that we should do designs workpiece namely, had set work, to good knife, other issue gives computer was finished. Accuracy is tall, rate is slower nevertheless, because we have the time morning only, the teacher sets an example to draw the graph that wants treatment on computer to us directly, input its cut machine tool, make its automatic cut. The so much operation on device of numerical control of the person that look is pressed twist, do not know to do it from where really temporarily, the teacher relapses explain to us, just be familiar with a few main operations gradually. We are called from inside graphical library finally give " heart " graph, send cut the system its, add cooling fluid during cut, the scintilla that part of the day of steel wire of the person that look gives, the outline of workpiece is clearer and clearer, can't help of exclaim project technology advanced, when designing a graph as a result of oneself regrettablly, did not adjust good shrink enlarge is small, ended up with a very fine writing, with the classmate of the group very happy. Although be in exercitation process very painstaking, but strong however denounce is worn our melting smile. Benchwork of the 4th class, on July 22, 2010 today, we should undertake the tireddest a type of work, benchwork, the teacher tells us, benchwork is labour of a complete armrest will make all sorts of parts, be can exercise a person to start work most of ability, a few great engineers, they take themselves seriously to be in very much of benchwork respect take exercise, and can very good control benchwork. Heard the teacher's word, we feel benchwork is a very marvelous type of work immediately, the experience should go well during the exercitation. Benchwork is in alone exercitation workshop undertakes, what we face is 3 giant workbench, a lot of table vice were installed above, use clip all sorts of workpiece. There are various tools on left, include: All sorts of hand hammer, handsaw, files, tap, front tooth, and underline a tool to wait. The teacher introduced metalworking to jackaroo to us all sorts of knowledge, as a result of the reason of working hours, the teacher asks we are done only today the basiccest curium and grind, I still am interested in these quite, can master it truly nevertheless, still want to give oneself long effort. From the basiccest beginning, ourselves elected some of board, design the figure that oneself want, five-pointed star goes up with powdery strokes on my preexistence armor plate, place it on vice, the line that with handsaw alignment has drawn has rhythm ground to move back and forth, this is one is compared kind physical strength is vivid, mastering good posture and skill still is laborious really, below the teacher's guidance, we begin to experience " the rope curiums wood is broken " feeling, preexistence curiums on initiative line give small mouth, next the right hand handholds curium handle, left hand tiger's mouth-jaws of death is pinned curium front, divide evenly fast pull use saw blade, the model in looking at him memory gradually clarity rises, happy drive of the heart the ache besides the arm. It is to want the end panel to curiuming to undertake file is versed in next, use rasp first, reoccupy fine file, the 5 horn heart that designs oneself is done brilliantly. Although benchwork is very tired, look at the achievement that oneself work hard hard nevertheless, feeling of a kind of achievement arises spontaneously, had struggled when oneself, pass hard, no matter encounter what difficulty, oneself are faced can hopefully, believe oneself, can go certainly! The 5th class is torn open outfit, metalworking jackarooed on July 29, 2010 now, the dirtiest vivid estimation should calculate tear open installed, two hands are stained with oily dirty, this is the first impression that Bencishi reviews. Tear open nevertheless installing is process of a more important field trip, the interior construction that it can assist us to understand all sorts of parts of an apparatus deeplier and working principle. The main shaft box that the job that the teacher gives us today is pair of lathe and tray undertake tearing open installing, the effect that knows each parts and the working principle with each in-house work. We are divided into a few groups to undertake, I enter of travel is pair of tray to tear open above all outfit, dropping screw to coming back simply do not have any problems, nevertheless the problem depends on how finding the breach that can disassemble, the iteration in oneself observes and the teacher's guidance falls, we a complete tray complete dismember, internal composition more is to rely on gear to come of transmission, if insert steel bar to wait,having some of additional design is to increase the firm sex of tray, reduce the friction of parts interior effectively through lubricant device, increase use flexibility, fumble carefully in oneself below, installation rises true and relaxed. The 2nd work that we do is to tear open box of outfit main shaft, the course that tear open is apparent much simpler than the first, take off main shaft box to build, present the one annulus before us to cover the gear of one annulus and pitch-black benzine, start work in everybody's collective discuss to fall with observation, be clear about understanding of this bloodcurdling device eventually, as handle of the right hand side jolty, gear can have 6 kinds job state in all, smoke gasoline tank to be below the roll of gear, compress cylinder, pump oil from one's store of valuables send, have the effect of lubricant gear, can realize petrolic to be used circularly again. Tearing open the process of outfit is more as dry as a chip, but study parts of an apparatus jointly together with the classmate, collective breath petrolic blames flavour, collective happy to realise the working principle of a certain link. Milling of the 6th class, on August 5, 2010 milling, regard the last metalworking of my university phase as exercitation type of work, oneself have kind of ineffable feeling, last class should throw him the attention of 100% , because had been done not have,issue section class. Today, the teacher introduced the sort of the relevant knowledge of milling and milling machine in detail to us, principle and use method. Milling machine cent is vertical and horizontal two kinds, the work that wants treatment is placed on the smooth clamp of workbench, rely on feed dial to undertake to its transverse, fore-and-aft the control that reachs fluctuation motion, and cutting tool maintains do not move, this and lathe just contrary. After the working principle of familiar milling machine and operation, the job that the teacher gives us is a cylinder cutting becomes square travel, the side of requirement square is long for 29MM, we place workpiece on smooth clamp, turn rotary table will dominate the niche of smooth clamp next, when cutting tool basically when centre position, begin pair of knives, after be opposite, turn two rounds according to requirement set dial half, treatment workpiece can rise 6.
5MM, can begin to process work, not a little while time, below the cutting of cutting tool, the square of a standard was born on milling machine. The treatment efficiency of milling is very tall, it is the commonly used tool that metallic cutting machines. Aborning is having wide application. Him hope can have more opportunities to attend the exercitation of this respect in the following practice, ceaseless him buildup start work ability. 6 the last word is short weeks trainee ended alive, the travel of our blue collar also drew a satisfactory full stop, acknowledgment school offers such opportunity for us, should thank our teacher deeply more at the same time, from them in teaching by personal example as well as verbal instrution, we benefit a lot, whats do not understand from inchoate, know to the profundity of all sorts of machines to now, master a few main operations. This second metalworking jackarooes -- your person hard dismiss from one's mind. 6 metalworking exercitation brings us, it is those operation skill of our place bring into contact with not just, also be a few kinds of ability that ask through place of a few type of work we take exercise not just, more according to oneself cases after needing our everybody to end in the exercitation go comprehending, go thinking over, diligent Shi Zimian, harvest somewhat, make this the exercitation achieved his real goal.
