CNC turret machine uses a large number of standard punch tools: holes of varying sizes, straight edges, commonly-used notches or mounting holes. By using a large number of strokes, with several different tools in turret . a turret press may make a wide variety of parts without having to first make a specialised press tool for that task. This saves both time and cost, allowing rapid prototyping or for low volume production to start without tooling delays.
CNC turret machine affixed in a position to make sure precise punching . The program triggers the ram, driving the punch through the workpiece. After the punch pulled back, the machine ready for preparing for the next hit.
A sheet of workpiece component gripped at the edges by workholders. Moving across the table into position in between the upper and lower portions of the turret by motion of two precision lead screws. Meanwhile, the turret revolves until the necessary punch and die set in place.
Other cnc machines developed to disengage the tool by spring motion rather than with the ram. This needs a separate punch holder and allows for strippers of metal rather than urethane. Metal strippers can hold the workpiece more tightly, especially during forming operations.
Advantages and Limitations of the CNC Turret Machine
The prospect to improve part appearance and precision with inexpensive specific tools in the turret press is in some cases overlooked. Mainly where nonstandard designs and components are concerned . The manufacturer is likely to advise the selective use of particularly shaped tools. Special tools, appropriately designed and used, can considerably improve dimensional control while minimizing burrs and improving feature appearance.
Certain design functions make the CNC punch press a prospect for better quantity manufacturing runs. For example, firmly spaced hole patterns and louvers as generally used for ventilation purposes . may require the use of two or even three progressive stations in a tough tool die to space the openings– at substantial added cost. This added tooling cost presents the CNC press its economical quantity strength in this example.
The CNC turret press pairs the distinct benefit of highly flexible manufacturing of prototypes with rather inexpensive manufacturing quantities. This is due to the extraordinary variety of standard punch configurations offered which makes the cost and lead time connected with special tooling not needed.
Another perk of CNC press processing is the incredible design versatility in configuration and size of features within the part. Newer machines, particularly models with indexable tool stations, make the nibbling of very large and complicated features a practical reality.
