OK, you all have a point here... calm down and look if we can get to something useful for all of us
I do know the spindle drive splitters and was always wondering if they are actually working.
The advantages are clear, you dont need a hydraulic set up, that dumps the price and gives the home-home owner a chance to split something.
It is right that the obvious relation motor HP vs ton rating can not be used here as it is a different method. Maybe there is a line between the 2 systems but what is see is that nobody knows at this moment.
What I dont see, and to me that is the point why this splitter is not performing, is the balance between power and speed.
Cutting something is based on 3 things: time, force and impact speed. (try this out with a knive and a citron, take your kids and they might learn something)
A die cutting machine cutting foils etc does not touch the bottom plate and still cuts a xx micron layer. This is defined by the impact speed and the time the knives are in the down position, force is a fix value defined by the construction and the avg 1ton/meter of knive.
With a splitter it is similar. IF the spindle drive would move faster it would split better but that requires a bigger engine torque so it does not stall at impact. The RESULT would be a faster cycle time.
The reason why they have 2 wedges is only a matter of concentrating all force to 1 line. It might help those with any splitter that sometimes is a litlle short of power.
Here it is presented as an advantageous design while it is only used to kind of mask its short-of power.
With a little material knowledge and calculation some engineer could figure out how strong the engine can be on the current construction, I am afraid that this would only show that these small splitters are build:
- strong in the safety-liability area
- cheap and weak in the mechanical side
Nevertheless i am sure that in the right dimensions these splitters can have real ton ratings comparable to hydraulics. Price would be an issue as a lot of other things (speed 1 of them) and thats probably why hydraulics are so popular and replaced a lot of spindle technology over the years.
It is a technological step back but i also still use a ladder and do not have an elevator everywhere. ... for some reasons
