CHP-1 Knock-Out Bar
Quantity in Basket:
Catalog No.: CHP-KO
Shipping Weight: 0.25 pounds
The CHP-1 Hydro-Press uses a hardened knock-out bar to stop
the movement of the downward-moving internal punch as the
ram continues down, ejecting the bullet from the die.
This is a spare K.O. bar for the CHP-1 press. It is a good
idea to have a spare, in case the one which comes with your
press is misplaced. The K.O. bar can be bent or damaged
if the bottom position sensor is adjusted too low to stop the
ram movement before stressing the K.O. bar, provided the
drive pressure is also set to a very high level.
Unlike the k.o. bar set for the CSP-2 press, only one height
of bar is needed. This is because the Hydro-press can be
adjusted for any top and bottom of stroke position, whereas
a mechanical press has a fixed top and bottom of stroke.
To adjust for different lengths of dies and punches, different
heights of k.o. bars are used in the hand press. In the
hydraulic press, the sensor is simply moved to establish
a desired top and bottom position for the stroke.
