Turning methods focus on the process turning and dispersion of turning France two types of processes, centralized process only one process can be completed one or several rings Turning, while the dispersion process to be several times the fixture to complete a ring Turning, they each have their own characteristics:
A centralized process characteristics
(1) a clamping cycle to complete most or all of the turning process, reduce the time of the ferrule fixture positioning errors and fixture positioning aids to improve the position and dimensions of accuracy between the surface of the ferrule, and improve productivity. For mass production of small rings in the multi-axis automatic lathe once the car is 2 to 3.
(2) shorten the process, reducing the intermediate storage, handling, transport links, to facilitate production management; reduced machine tool equipment and tools for the amount.
(3) conducive to automation and mass production, shortening the production cycle, reduce production costs.
But at the same time have higher requirements for process equipment such as lathes, tools, fixtures and tools and the workpiece blank. Such as requiring less rough to stay and size of higher accuracy, more stringent requirements on the microstructure and hardness of surface quality; requirements lathe higher power, higher rigidity and machining accuracy and degree of automation, often with multi-tool technology and equipment, multi-step, multi-station multi-axis semi-automatic machines and automatic machines, the general mass production should adopt the multi-axis automatic machine, semi-automatic lathes in small quantities and processing models varied should be multi-knife; The type and quantity of specific and strong, replacement Model trouble, adjust the difficulty and time-consuming, require a higher skill level of workers, the need for rational organization of production management.
Dispersion characteristics of the process method
(1) is suitable for medium, small batch and single-piece production. Easy to organize production, lathes, jigs, simple and economical, easy to replace bearings models, and low cost. Connect a single computer to automatically line, is also suitable for mass production.
(2) can be used with good rigidity, large power efficient special lathe to process, easy to select the optimum process parameters, the available high-speed take the knife cutting to improve the processing efficiency.
(3) can be achieved on the stand-alone automatic loading and unloading, automatic tool path and automatic measurement machine easy to operate, the workers, the technology is not high.
(4) on the ring blank not ask for much, all kinds of form, size, precision volume of varying rough can adapt.
"Decentralized procedure" process and the length of routes, processing time and the process stopped a long time storage, transportation, inspection, loading and unloading, a ferrule is subject to multi-machine, multi-process, multiple clamping positioning, more than the operation and check positioning errors, poor machining accuracy. Human, financial, material and energy consumption.
In summary, the use of "focus on turning the Act is the development trend of" decentralized procedure "is the production of limited, small factories using.
