5.2.2. Setting of Vice Side Clearance

In order that the feed system may work accurately, there must not be any guide clearance on the moving vice gripping
jaws. Therefore, the vices must be regularly checked and adjusted.
• open the vice to maximum length
‚ release the lock-nuts M8 and bolts M8
ƒ tighten slightly the first bolt (of the vice plate), until it touches the groove
„ secure it with the lock-nut in this position
... move the moving vice to the place of the adjustment of the previous bolt
† repeat the items ƒ, „, ...
‡ proceed in this way until the vice is closed and adjusted.

5.2.3. Moving Vice Feed System
The standard equipment of all moving vice models is a retarding system in end positions, both when the material is moved forward
and backward.
Description of Cycle:
The moving vice clamps the workpiece, starting slowly to move forward (approx. 4 mm); then the induction sensor switches the
hydraulic system over to the fast feed and the last 4 mm before the end position is achieved, it again switches over to the slow
retarding speed. The same process repeats when the vice reverses. This system ensures maximum accuracy of workpiece feed,
prevents workpiece skidding, delayed actions in end positions and mechanical impacts in the entire system. The retarding system
also eliminates the weight loss of the work piece while it is gradually being cut off.

5.2.4. Setting of Feeding Speed of Moving Vice

The standard equipment of the hydraulic cylinder of the moving vice feed system in all NC Automat models is a control valve, which
enables continuous setting of the feeding speed of the moving vice.
The correct speed setting affects the speed of the cutting cycle including the accuracy of the feed. Lower speed of feed is used for
heavy, full materials, for which the maximum accuracy is required. On the contrary, faster feed can be used for sections, which are
usually longer.

5.2.5. Setting of Auxiliary Roller
The auxiliary roller moves on guide rods and serves for supporting

short (end) workpieces, which do not reach the firm roller track.
The auxiliary roller should be adjusted outside the zone of movement
of the feed vice according to its feed length.
