Normal > (1) the model of machining center is current the work out method of model of our country machine tool is to press JB 1838, 1976 standards, the method of model work out of machining center, according to the apply mechanically of work out method of model of general or special machine tool. Give typical examples of machining center model: The category of the machine tool expresses with letter of Chinese Phonetic Alphabet, " T " represent anxiety bed kind etc. Characteristic code name also gives with letter of Chinese Phonetic Alphabet after category code name express, machining center gets the better of code name to be H commonly especially (change a knife automatically) : Group, model fasten code name to use arabic numerals composition, after be located in category code name or characteristic code name, word of the first digit expresses group not, word of the 2nd digit expresses model not; The machine tool is main parameter expresses with coefficient, machining center expresses the 1/10 of workbench width with two digit word. The machine tool is major the suitable serial number of remodel, english letter waits to express with A, B, C, D after model of primary machine tool. (2) the type of machining center 1) machining center of vertical of vertical machining center is the machining center that shows main shaft is verticality, if pursue 2, 1 is shown. Its configuration is stationary mast more, workbench is a rectangle, without graduation circumgyrate function, suit to machine dish, set, board kind spare parts, it has reference axis of 2 sharp movement commonly, can install the circumgyrate station that axis of an edge level rotates on workbench, in order to processes corkscrewed yarn kind spare parts. Vertical machining center installs card to go to the lavatory, facilitating operation, observe treatment condition easily, it is easy to debug a program, application is wide. But the restriction that accepts pillar height to reach the unit that change a knife, cannot machine too tall spare parts, when treatment antrum or sunken face, cut bits not easy eduction, serious when meeting attaint cutting tool, destroy already machined the surface, affect the success of treatment. 2) the machining center that machining center of horizontal of horizontal machining center points to to main shaft is horizontal condition, if pursue,22 are shown. Horizontal machining center is contained normally automatic graduated circumgyrate workbench, it has 3 ～ commonly 5 motion coordinate, common is coordinate of 3 sharp movement add coordinate of motion of a circumgyrate, workpiece installs card hind in, finish except the others beyond installed surface and end face the treatment of 4 surfaces, it suits to increase top part put oneself in another's position most kind spare parts. Compare with photograph of vertical machining center, bits of the platoon when horizontal machining center is machined is easy, advantageous to treatment, but the structure is complex, the price is higher. 3) dragon door type type of door of machining center dragon the appearance of machining center and likeness of numerical control planer-type milling machine, if pursue,2-3 place is shown. Machining center main shaft is dragon door type more perpendicular setting, except trade knife unit automatically beyond, still contain the accessory of main shaft head that can change, the function of numerical control device is more all ready also, can one machine is multi-purpose, apply to treatment especially the workpiece with large work and complex form 4) 5 axes add T center machining center has 5 axes the function of vertical machining center and horizontal machining center, if pursue 2, 4 are shown. 5 axes machining center, after workpiece is installed, can finish except the others beyond installed surface the treatment of 5 faces. Machining center has common 5 axes two kinds of forms: One kind is main shaft can rotate 900, undertake to workpiece vertical and horizontal are machined; Another kind is main shaft not haul, and taking workpiece to rotate by workbench 900. , complete pair of work the treatment of 5 surfaces. 5) empty axis if machining center pursues 2 show 5 times one. Machining center changed empty axis before the structure of traditional machine tool, pass the motion of connecting rod, implement the campaign that main shaft much freedom spends, complete the treatment of complex to workpiece curved surface.
