Bearing seat drill hole aggregate machinetool jig analysis A. According to the work piece different working condition, ma y differently have each kind to insta ll the method: A) adjusts the peaceful process。 6) attacks the silk. 2 pound cutting tools cutting specificationses putation specifications character istic The aggregate machinetool norma l work and reasonably selects the cutting specifications, namely the determination reasonable cutting speed and the work enters to the quantity has the very big relations. The cutting specifications elects the inappropriateness, can cause the aggregate machinetool to reduce stops the loss, enhances the production efficiency, lengthens the cutting tool life, improves the processing quality. a set of design 1徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計 (論文 )3. Is processed 7 holes dia meters is , the processing hole dia meter with leads a set of length, leads the set of inside dia meter size, about the deviation as well as the hole spool thread idea l position displacement relations, like table 1 shows. 4. May know 1 ~ 7 holes by table 1, as well as 8 ~ 10 holes and the bottom hole dia meters are mm, it needs leads a set of length for (32 ~ 40) mm, the inside dia meter size deviation is + ~ +, hole spool thread idea l disa lignment for ( ~ ) mm. 5. Hole processing cutting specifications putation A Processes this casting HB=204 with the highspeed steel drill bit (to drill 1 ~ 7 holes, II location。 S= ( ~ ) mm/R。Soda ash % ~ %. Attacks the silk when the cast iron work piece, then all uses the lubr icant, by enhances the super ficia l evenness, reduces the power the consumption. Usua lly uses the petroleum, also ma y use the curing cutting pound and the oil mixture and so on. The refrigera nt current capacity should according to the cutting tool form, the dia meter size, the processing method, the cutting specifications and so on the concrete condition determine that, the aggregate machinetool design use exper ience indica ted, to boring cutter, drill bit as well as a milling cutter kind of cutting tool, each cutting tool refrigera nt mean discharge approxima tely for (2 ~ 6) L/Min. The overseas materia l remendation according to the processing dia meter choice, the cutting tool refrigera nt current capacity, the value see ever y time Table 2. 7 operating cycles expla nation A aggregate machinetool, its operating cycle is quite plex frequently, not only has severa l power heads to carry on the work according to the different circulation, moreover these circulation also needs other parts, like moves the work table, coordina te movement and so on rotary table as well as drum wheel. Various powers part keeps off the iron with the aid of the procedure control, carries on the work according to the stipulation order. The operating cycle must as far as possible be simple moreover controls the part to be supposed to be few, otherwise the engine bed production cost enlarges, the security performa nce also can reduce. This aggregate machinetool suits in the mass production uses, the production efficiency
