Come realizzare i vantaggi della macchina a cinque assi?? Ecco un esempio di una macchina Haas UMC-750P che elabora 28 parti contemporaneamente. Attraverso la progettazione del giradischi e dell'apparecchio, e le tre superfici di lavorazione del pezzo vengono combinate in un unico programma di lavorazione nel programma di lavorazione a cinque assi, lo scopo di ridurre il tempo ciclo è raggiunto.

The turntable can expand the original processing space through precise positioning. The well-designed fixtures can not only improve the processing efficiency, but also reduce the idleness of the machine, and the operator can reduce a lot of work.

Per esempio, to process the first three faces of the parts shown in the figure below, if the clamping method of the vise is used, a total of 264 seconds are required for each part (the clamping time is not counted).

By designing a more compact fixture and making full use of the processing space provided by the turntable, it has the opportunity to process 28 parti alla volta.

In the production of fixtures: Choose an aluminum alloy with a size of 114mm*114mm*550mm as the base. Use positioning pins for positioning, and use compression fixtures that take up less processing space for faster clamping.

Then mill the four faces of the base body, and machine a positioning pin hole for each part, two grooves for avoiding empty locking fixtures, and two threaded holes for locking. This is all the production steps.

The complete set of fixtures includes: 28 positioning pins, 56 positioning locking blocks (reusable), 56 screws and wrenches. This fixture design can shorten the original processing time from 264 seconds to 202 seconds (not counting the clamping time). This means that the processing time has been reduced by 23.5%

Not only that, because the machining program has merged the three machining surfaces of the part into one CNC machining program. In questo modo, the cycle time of a single program becomes 95 minuti. During this period, the machine has been maintaining processing without waiting for the operator’s frequent clamping, which will greatly reduce the labor intensity of the operator.
