The chuck clamping apparatus of lathe basically is the clamping apparatus that points to installation to go up in lathe main shaft, this kind of furniture and photograph of machine tool main shaft join and drive workpiece to rotate along with main shaft together. Intelligent numerical control leads 10 thousand nations today everybody understands chuck of numerical control lathe how to be chosen together below everybody looks together. Lathe kind chuck clamping apparatus basically divides two kinds big: All sorts of chuck, apply to kind of spare parts and dish of short axis kind the clamping apparatus that the spare parts machines; Fixed position of central aperture, centering installs the clamping apparatus of workpiece, apply to length dimension the axis with treatment bigger or more working procedure kind spare parts. CNC Turning treatment asks clamping apparatus should have taller fixed position precision and tigidity, structure simple, versatility is strong, facilitate on the machine tool clamping device is reached assemble and unassemble quickly the character such as workpiece, automation. 1, all sorts of chuck clamping apparatus are in treatment of numerical control lathe, most circumstance is use workpiece or semifinished product outside round fixed position, the following kinds of clamping apparatus lean namely circumferential the clamping apparatus that will locate. 3 claw of ⑴ of 3 ungual chuck chuck characteristic 3 ungual chuck are commonly used lathe general clamping apparatus, the advantage with 3 ungual big chuck is OK automatic centering, clip holds range big, the rate that hold clip is rapid, but error of centering precision existence, unwell the 2 outfit clip that spends the work with high demand at coaxial. To prevent be out of shape because of workpiece with vibration influence machines quality when turning, when workpiece is placed from centering chuck traditional Chinese clothes in 3 claw, its are dangerous extend length to should not be too long. How is chuck of numerical control lathe chosen? For example: Workpiece diameter ≤30mm, its are 3 times what extend length to should not be more than a diameter more dangerous; Be like workpiece diameter > 30mm, its are 4 times what extend length to should not be more than a diameter more dangerous. Also can avoid workpiece to be supported to curved, top falls and cause the accident that hit a knife by lathe tool at the same time. ⑵ blocks ungual CNC lathe to two kinds of commonly used standard chuck block claw, it is strong card claw and soft card claw. 2, hold when clip blocking claw go up in raw face, be like, cast or surface of coarse club makings, when needing large clamping force, use strong card claw; To assure normally stiffness is mixed wearability, strong card claw should have heat treatment, hardness is taller. Reduce two when need or diameter of many spare partses is jumpy deviation, and when already machining a watch and hoping to have clip mark, should use soft card claw. Soft card claw uses mild steel to make normally, before soft claw is being used, be machined to cooperate workpiece, want to undertake boring hole machining. Although still can maintain certain positional precision via holding clip for many times,the big characteristic that soft ungual outfit places is workpiece. CNC MillingCNC Machining
