For those people planning on buying the four way bottom die, what method will you use to hold the die centered on the bed? Additionally, do any of you plan to implement die holders for the other bottom dies? If so, be careful choosing your tooling as some punch and die combinations will not work together even when using even a minimum 1” tall die holder.
I believe the bed floats and it has bolts on the front and back that can be adjusted to center the bed. Good call making people aware about different punch and die setups. Never take for granted they will be centered.
Hey guys, we have inventory of adapters that hold 4 way die centered on the table via the 1/2” slot. Those will be available for purchase along with the machine, tooling, and accessories.
Down the road we hope to offer staged tooling (that is the closing distance is the same for all combinations) but we’re not there yet.

Daniel, will you offer package options for the dies? Such as one full set of each package.

Basically at checkout there is a matrix of tooling (rows) and segment lengths (columns). In each cell there’s a drop-down menu where you can select the quantity you want of each segment. So it’s very easy to pick exactly what you’ll need tooling wise.
Just as a PSA, we are going to need to artificially limit quantities of tools any one individual can initially purchase. The quantities allotted will be pretty considerable, but we just want to prevent early customers from buying so much tooling that we run out for customers down the list. Our tooling supplier is working hard to increase their production capacity as we believe demand for tooling will be very high and we want customers to have the freedom to buy as much tooling as they want/need in the future.

Ok, thanks for the update.

The bed has an extra wide slot down its length, usually 5/8” wide. This is not intended for the direct placement of dies. If it were, there would be far more than the six set screws shown on the 25T. The wide slot is for the placement of a die riser block. The die block goes in this slot and is adjustable fore and aft via the set screws to bring the lower tool into perfect center alignment with the top tool. Common set screw spacing on die blocks are four inches on center and can be made with much closer spacing if desired. Particularly handy when using segmented tools. The die block serves another purpose, that of protecting the bed from damage which is common when applying too much tonnage to a narrow bottom die. Imagine placing tooling in a wide slot and not being able to center it for a lack of set screws in a wide slot. Slots in die holders are 1/2” wide just like the tangs on all American style tools. My point in my first post was that the one inch vertical space that a die block requires makes some of the tooling offered too tall to use in a machine with only nine inches of open height. Calculate which combinations of upper and lower tools will work based on their combined height while recognizing you need adequate space between the tools to insert your work, usually 3/4” minimum. In thirty years of press brake work l have not seen a press brake that did not include a die riser block.
The slot on the Titan table is 1/2” wide to accept direct mounting/locating of the dies. We measure the alignment of the centerline of the slot to the centerline of the punch clamping feature on the ram to ensure that it’s less than .005” error along the entire length (shimming if necessary)
The tapped holes on the front and rear faces of the table are for forwards compatibility of clamping blocks, etc.

For those interested, here’s how we check alignment. The lower block has two slightly undersized dowel pins that drop into the slot so that when it’s clocked either direction it puts to the single 1/2” pin exactly in the center of the slot. The upper gage has two pins that are 1/2” diameter and lie tangent to the plane formed by the punch clamp reference edge. Using standard calipers to measure across the 3 pins yields the alignment error (.500” measurement meaning perfect alignment)
It’s also worth noting that we built gages to check perpendicularity of the table surface, parallelism of the relevant ram surfaces, and parallelism of the table mounting surfaces and linear bearing mounting surfaces on the uprights. We 100% inspect all of these parts. These features are all controlled within a few thou.

Thanks for the updates @langmuir-daniel ! Very excited to receive my email.
Is there anyway that we can get a picture of the centering adapters for the 4-way dies?
That will work great if a person is able to afford precision ground tooling which is manufactured to an accuracy that guarantees the tools will be on exact center line regardless of which way they are installed. The very reason that the slot in your bed should be 5/8” wide is to compensate for non precision, standard tooling. Which is also the reason you have set screws on both the front and back side of the bed, in order to set the top and bottom tools aligned with the centers of each other.
All American tooling that i know of has the tang centered to the apex of the tool. Our tooling is made to the a precision which allow centering to occur without any adjustments. Nonstandard or inaccurate tooling will require the use of an adapter and some ‘pusher blocks’ secured to the front and back of the table to center it.

Are you saying then that the tools we will be offered are precision ground tools? Or will these be planer machined tools? Not trying to be difficult here. Just the opposite. I am anxious to receive my 25T and plan to take advantage of the tooling that is being offered. Please help me understand how a “Pusher Block” which is a press brake term I haven’t heard of is going to allow a person to center the tool when that tool is secured in place by its half inch tang in a half inch bed slot.
He is suggesting a adapter of some type
What I’m saying is that the punches and dies we offer are manufactured such that the centerline of the tang is aligned to the centerline of the tip of the tools within in a few thou. This accuracy allows for direct mounting of the punches and dies without having to do any type of alignment after removing and replacing punches/dies.
If you are planning to run either homemade or poorly manufactured dies where the tang is not well aligned to the centerline, then what I suggest you do there is to make yourself an adapter that’s allows you to manually align the die instead of relying on the slot.
By ‘pusher block’ I was referring to a series of blocks bolted to the front and back of the bed that are equipped with set screws so that the tangless die (such as a 4 way) could be pushed back/forth into alignment.

Any pics of how the 4 way is held in place?
Obviously it doesn’t use a tang so the above debate doesn’t matter.
The 4 way die holders we will sell have a 1/2” tang that engages the slot in the table, and slot on the top that the 4 way die rests in. We sell these holders in 6” lengths. Pictures should be up sometime soon of the holders and all of the punches and dies.

Wish you would sell these holders is 16" lengths . I can guess since the 4 way dies are available in up to 16" most people would buy 16" minimum. Just food for thought.

We were concerned with being able to hold such tight tolerances on these holders over extended lengths- hence the 6" segment lengths. Your best bet would be to purchase 3 of the holders to support up to 18".
