The correct and safe attachment to the turret of the live tool
blocks and the tools they will hold should be confirmed prior to
operation of the live tool.

Before mounting the Live Tool in the machine, we recommend
lightly greasing the drive.
n
If any abnormal noise or excessive vibration are detected dur-
ing operation of the live tool, immediately stop the operation of the
tool and contact the service department at MPT/SMW Autoblok.

those described here, is forbidden
SMW Autoblok is not responsible for damage to property or injury
caused by improper use of live tools.

mounted in the nut first, then the nut must be screwed on to the
threaded shaft, using the proper wrench.

Attach the collet nut using wrench "B", keeping the shaft steady
with wrench "A" (see the picture).

4.2 ANGULAR LIVE TOOLS LT-A
The LT-A (angular Live Tools) should be lubricated every 3000 run-
ning hours. This interval is dependent on the operating conditions.
For safety reasons, the Live Tool must be dismounted from the tur-
ret and placed on a work bench to be greased:
- open the greasing screw (do not lose or damage the safety seal);
- hold the LT by the drive and manually rotate the tool. Insert 2
grams of HPG-LT grease, then rotate the tool spindle 90° and insert
2 more grams of grease. 2 grams of grease should be inserted for
each 90° of spindle rotation (approx. total grease quantity min 5
max 7 gr., according to LT size);
- remount the LT on the turret again, ensure that the mounting
bolts are properly tightened, and that the ER collet nut is properly
attached;
- let the tool rotate for approx. 2 min. at a speed of 100 rpm, to
allow for even distribution of the grease.
n
CAUTION: when you begin rotation of the tool, do not exceed
3.000 rpm for approx. 1 min.
4.3 ANGULAR LIVE TOOLS WITH OFFSET LT-S
The LT-S (angular Live Tools with offset) should be lubricated every
3000 running hours. This interval is dependent on the operating
conditions.
n
CAUTION: when you begin rotation of the tool, do not exceed
3.000 rpm for approx. 1 min.
4.4 LIVE TOOL LT-T - 180° TILTING MODEL
The LT-T (180° tilting model) must be greased every 1500 hours,
depending on the operating conditions.
n
CAUTION: when you begin rotation of the tool, do not exceed
3.000 rpm for approx. 1 min.
4.5 LIVE TOOLING WITH INTERNAL PASSAGE OF THE LIQUID
REFRIGERANT.
The live tooling with internal passage of the liquid refrigerant
have seals that can deteriorate without an accurate filtering water
(between min. 0.01 max 0.02 mm.).
These live tooling can be used only with water emulsified with an oil
percentage between 3% and 5%.
5. SPARE PARTS AND SERVICE
Live Tools are complex components. Genuine MPT/SMW Autoblok
spare parts are available from your authorized MPT/SMW Autoblok
distributor. We recommend you return your live tool to MPT/SMW
Autoblok for all necessary service. Our factory trained engineers
and technicians will provide the proper level of service to maintain
a long service life of your live tool.
