Look at any high production machine out
there and you'll see pallet changers, tombstones, and high density
workholding fixtures. The industry has figured out that to maximize
profits you have to maximize spindle time. The
more parts you can get in a machine per cycle and the faster you
can get them in and out translates into bigger profits.
The problem is that these "efficiencies" have such a high
initial cost that you might not see any return on investment until
several years down the road. The
Pierson SCPS
provides all the efficiencies
of high density workholding and fast part change-outs without the
astronomical price tag. Please check
our Applications page and see how
much our customers are saving on jobs.

Several reasons. First of all, vises rely
on holding objects using brute clamping force. Our workholding systems hold pallets with a downward force. Once locked, resistance
to movement in the X and Y directions are not dependent on clamping
pressure. This downward locking method assures that there is no
excessive pressure exerted on the pallet
which might cause distortion or bowing.
Second, the system has a repeatability of .0002. With vises, the constant clamping
and unclamping distorts a pallet either by bowing it or by compressing
the material so much that accuracy starts declining from the first
crank of the vise handle.
Since the system is
air actuated, you'll never have
to deal with a vise handle again.
It's as simple as flipping a single hand valve. Best of all, you'll
be swapping fixtures in and out
of the machine in about 15 seconds. No
vise can compete with that!
Finally, pallets are easy
to install and ready to go right out of the box.
They also come in sizes that would not be able to be held in a standard
capacity vise without time consuming modifications. This means faster
fixture creation and more parts per fixture.
A SCPS will work with any vertical machining
center or knee mill. The Connection Kit contains all the components needed
(air fittings, air lines, hand valve, grommets, instructions) to begin using
the SCPS in your machine. The only other thing you'll need to provide
is an air source with a minimum of 100psi for operation.
Mounting
the SCPS Base is easy. The SCPS Base mounts to your table with the
same T-slot nuts that a standard vise uses. We even include the toe clamps and bolts.
Vises have been around for a long time
and have their right place in manufacturing. Pallet systems don't
have much benefit on prototype and short run jobs, but pallets
are not always for holding parts!
Many of our customers use our Speed Change Pallet System to hold
and store vises, indexers and clamping fixtures.
Imagine bolting your current vises and rotary indexers to pallets
and simply dropping them onto your table with no need to indicate
them ever again! For more ideas on what people are mounting to
their pallets, check out the Applications
page.
Not at all. The SCPS still maintains a tremendously high locking force of over 3000 lbs due to its powerful springs. This is more than enough to maintain a secure hold. Plus, other systems use
hydraulics which can be a great liability of losing holding power should the hydraulic pump fail. The SCPS is designed to be failsafe. The air lines can be completely removed and the system will continue to stay locked.
Spreading a light coating of grease on the alignment pins and locking bearings is all you'll need to do to ensure consistent holding force. This should be done on a regular maintenance schedule as outlined in the SCPS Manual. Because all critical components are hardened, the SCPS has shown very little wear after 100,000 test cycles. We've found that the best preventive maintenance is to keep the system clean, covered and dry when not in use.
Our goal is to provide quality products
that are in every shop's price range. Currently a SCPS starter kit
is $1995.
Yes, substituting a different size pallet for the 8 x 12 that comes with the Starter Package is not a problem. We simply add the price difference between the two pallets to the cost of the package. Our workholding store will automatically quote the price for different pallets.
All of our products can be purchased directly through us.
This allows us to establish a close relationship with our customers and provide the best applicaton advice possible. Please visit our workholding store or give us a call to place an order at (800)
352-2894. We accept all major credit cards and company checks.
