An important issue even today. What is tolerance? Who defines the tolerance? The tolerance is directly related to truth and freedom …
Before I become philosophical here … Back to pikchain®:
One of the questions about pikchain® that keeps coming back: How high is the tolerance of pikchain®, and the positional accuracy?
Well, the pikchain® has a positional accuracy of about 1 mm. The size is similar in width, maybe a bit less, but again we need a certain buffer so that the chain can still proceed freely and does not clamp.
Do you want to have a lower tolerance? Do you want to position more accurately?
Of course, the pikchain® can also become intolerant, or it can be positioned precisely in all axes.
It would then work, for instance, like this:
In order to obtain a desired position tolerance in height and width, the tool holder on the pikchain® is spring mounted. This tool holder is given a running carriage, which in turn enters into an adjustable roller guide. This roller guide is set for the desired tolerance once. Ready!
See also drawing.
We also have a solution for the positional accuracy in the longitudinal axis. The above-described tool holder gets a lateral bore into which a position mandrel can enter from the outside and keep the chain in position during the operation of the corresponding tool (e.g. drills). Ready!
You see: If we want, we can be damned intolerant. Otherwise we remain tolerant, freedom-loving Rhinelanders!
