Makino has patented a vise that we've named the Rotary Smart Vise.
It is a vise that allows you to place the intermediate plate in between
two grippers in grooves manufactured into the plate. By clamping
between centers, it isn't necessary to hold the workpiece very tightly
because the cutting forces are relatively small compared to the
clamping forces (one-half to two tons).
The Rotary Smart Vise design allows us to clamp through the part as
opposed to a conventional vise, which can cause bending after
machining, particularly in a thin part with a complex surface. This
allows for much higher accuracy during production of the intermediate
plate.
This vise allows for good access and no distortion. It provides
access to the front, back, and even sides of the component, in one
setup. This allows for bench-free production with limited setups.
Some of the beauty of the function of this vise is the way it
actually holds the part. We cut a concave form into the workpiece. Into
the rotary workform on the jig side, we cut a convex form. Now we have
a repeatable form on both the jig and workpiece, so if we ever need to
come back and rework the part, it's easy to do. It's also a very
effective method for holding a part while still giving us access to
both sides. This particular device also allows us to have the workpiece
out in space, providing excellent accessibility. Here we're looking at
the clamping of the vise.
This patented device lets us mill the core and cavity, mill the
pocket of the sliders, drill the water holes, and drill and tap the
rear side, all in one setup. This minimizes setup, teardown, and
improves accuracy by eliminating a lot of stack-up error.
The other thing that can be done using the Rotary Smart Vise is you
can actually cut the core and cavity simultaneously in the same block
of material. We can cut the core on one half of the block and the
cavity on the other half. The accuracy of the core and cavity can be
outstanding in this way, while minimizing your setup. Later, you
separate the block with a wire EDM.
Here we have another example of that same part where we have both
the core and cavity, machining simultaneously on the same block,
accessing the sides of the part. When we've completed all the
machining, we'll wire-cut the block to separate the core and cavity.
Another thing about the Rotary Smart Vise is we'll be using it to
manufacture the intermediate plate, but it can also be used in 2D mold
production to minimize setups and to aid the machining of angled
surfaces in a production environment. It increases productivity and
improves surface quality, allowing you to index the Rotary Smart Vise.
This allows you to make one simple, straightforward cut when cutting
angles.
Here's an example of drilling for water holes. We're indexing the
part around 180 degrees and drilling access, heating, and cooling
holes.
The Makino Rotary Smart Vise provides a technique for accessing both
sides of the intermediate plate for continuous machining. It also
facilitates the production of the channels consistent with the part
profile, but also maintains a uniform distance for the best possible
thermal characteristics. It also provides access for side water holes,
ejectors, etc. and is a chip-friendly design in that the part is
supported in space, so chips easily fall away from the part. It also
allows for shorter tool reaches for more rigid tools.
Here's another example of machining on both the core and cavity.
We're cutting both on the same plate, using the Smart Vise to gain
access to the front surface, back surface, and the edges.
Makino's contribution to this weldless process is the highly
accurate machine and the Makino patented Rotary Smart Vise function,
allowing the intermediate plate to be manufactured.
Therefore, the optimum way to produce a 3D weldless mold is with a
Makino and a Rotary Smart Vise, which also allows you to minimize
setups and improve accuracy on all complex mold work.
