Manufacturer's Warranty - REMS Unimat 75 Instrucciones De Uso

GBR
The die stock chaser is inclined in the holder in accordance with the thread
pitch. Angle d must be set on the die stock chaser in accordance with this
angle of inclination (Fig. 9) so that, after installation in the holder, the tooth
crests of the die stock chaser lie on a plane parallel with the base of the
holder. In this process, a tolerance of +/– 0.05 mm must be observed. In
addition, when die stock chasers delivered retrospectively are installed,
attention must be paid to the angle of inclination in the holder, since it is
possible to install different die stock chasers in several holders for the pur-
pose of cutting fine threads.
Guide teeth are machined into certain die stock chasers to improve pitch
tolerance when cutting longer threads. These must be restored when the
die stock chaser is re-ground.
5.4. Setting the chaser dies in the holder
Care must be taken that the numbering of the chaser dies tallies with that
of the holder and that the fitting chucking plate does not project above the
holder faces. Projections must be removed if necessary (e.g. ground oft).
To set the chaser die in the holder (Fig. 10) to the dimension 55.4 mm in
the REMS Unimat 75 or to 95.4 mm in the REMS Unimat 77, the screw
of the chucking plate (25) is tightened securely. The stated dimension must
now be set using a dial gauge or the supplied setting gauge (Fig. 8) – as
shown in Fig. 10 – between the lower edge of the holder and the first tooth
after the initial cut. To do this, the die stock chaser must be pressed for-
ward by means of the adjusting screw on the underside of the holder. The
adjusting screw must be in contact with the die stock chaser under pres-
sure. In the case of the REMS Unimat 75, the distance of 55.4 mm (Fig.
10), with a tolerance of +/– 0.05 mm, must be observed. For smaller threads
(diameter 6–12 mm), it can be adjusted to 54.3 mm to good effect. It is,
however, important to maintain the tolerance of 0.05 mm within the 4 die
stock chasers of the die set. In the case of the REMS Unimat 77, it is ad-
visable to observe the specified distance, i. e. 95.4 mm +/– 0.05 mm.

7. Action in the event of faults
7.1. Fault:
Thread ragged, crests and split off.
Cause:
· Blunt chaser dies.
· Bad coolant.
· Setting dimension of chaser in holder incorrect.
· Wrong speed.
7.2. Fault:
Thread is badly cut, "ragged fine thread".
Cause:
· Holder incorrectly inserted in die head. Comply with correct
sequence!
· Chaser dies incorrectly fitted in holder. Comply with correct sequence!
· Chaser dies in wrong holder model (inclination angle!).
7.3. Fault:
Thread not centered on the workpiece.
Cause:
· Vice centering altered.
7.4. Fault:
Die head does not open far enough.
Cause:
· Wrong closing lever fitted.
· Closing lever worn.
· Triggering cam worn.
7.5. Fault:
Die head does not close.
Cause:
· Clogging.
· Incorrect insertion of die set (see 3.3).
· Incorrect fitting of chaser dies in holder (see 5.4).
