Holding Block Pre-Load Setup; Horizontal Vise Position; Vertical Vise Position - Kurt DL640 Installation & Operation Manual

Holding Block Pre-load setup

*PRE-LOAD PARTS.
(* Is defined as ability to clamp one part first with limited pressure before
second part is installed.)
Caution: Pre-Load places only enough spring pressure to hold one part
and are not intended to clamp part for machining. Both stations must be
clamped to achieve clamping pressures.
NOTE 1: In all jaw settings, unless both parts are the same size, the Widest
part must always be mounted in the Rear Jaw Set. See figure 3 page 6.
NOTE 2: Same size part, Pre-load must be setup to clamp front part.
Horizontal vise position (reference sketches on page #6)
1. Open both Moveable Jaws sets to accept part being clamped.
2. Place one part into each station and close.
3. Open only enough to release pressure from each parts.
4. Remove the part that is planned to be pre-loaded. (Vertical vise position
see caution below)
5. Leaving the opposite part in the vise, begin to close allowing the Holding
block to slide 3/16" minimum. See figure 4 page 6.
6. Begin to open and both Movables will open.
7. Remove all parts in the vise.
8. Your Pre-load is now set.
9. Place part to be Pre-loaded in and begin to close until part is clamped.
Install opposite part and clamp.

Vertical vise position

Caution: In this position, the horizontal vise position setup is used but we
recommend to always setup with the pre-load in the top station. The
Stationary Jaw is a fixed stop where the bottom Moveable Jaw will have
movement and part could appear to be pre-loaded and part could move
causing personal injury. Please use caution at step #4.
