Electric spindle is a
high-speed high-precision components rigidity, we must strictly follow
the practices used spindle spindle motor, otherwise it will increase
equipment failures, shorten equipment life. Please use the rule as
follows:
(1) Before the boot,
first ensure that the spindle cooling system to work properly, and then
turn the power spindle. Do not use the spindle without the cooling
conditions, it is necessary to check the fan and pump are working
properly before use. If the spindle is water cooled, to check whether
the cooling water containing impurities to ensure water is smooth.
(2) When using electric
spindle, spindle from low according to the principle of high speed,
gradually increasing speed to warm up, when the spindle load up to speed
and smooth operation of the state after the required processing, can
better protection spindle, to reduce the wear.
(3) during use is
strictly prohibited beat, hit threaded spindle clamp and rotor end, so
as not to reduce the component life, affect the results spindles used.
(4) During the
operation, the tool must be replaced in the correct way. When the knife,
the focus should be uniform, the tool should be aligned with the
threaded end of the screw rotor, clamping can be. During operation the
tool needs to be replaced before the replacement to wait Spindle
cooling, avoid tool change at hot temperature state.
(5) During the
operation, if the fixture card spindle rotor end, non-beat way to remove
Jigs. Only under the premise of no damage to the rotor shaft threads
with pliers and other tools to remove the chuck, and clean the rotor
tapered bore and clamp the spindle to avoid Movies shorten life,
affecting the quality of workpiece. If the fixture has completely lost
precision, it must be replaced immediately.
2. The spindle maintenance specification:
(1) to control the
spindle actual time worked. Theoretically prohibit spindle 24 hours of
continuous work, operating 12 hours per spindle Spindle let rest at
least 2 hours, in order to prevent the formation of shortened due to
mechanical fatigue life of the spindle.
(2) to understand the
conditions, the ambient temperature and the spindle temperature control.
Spindle operating ambient temperature not higher than 35 centigrade
degree, when the ambient temperature is above 35 centigrade degree
should use air conditioners or other protective measures to reduce the
room temperature, thereby reducing spindle temperature.
(3) The spindle cooling
water must be kept clean and free of impurities, recommendations to
clean up after the end of the spindle shaft waterway, scale and water
holes to avoid clogging due to rust. Also, always pay attention to
circulating water temperature in the tank, so the water temperature is
too high, the cooling effect can not be achieved prefetching.
(4) Always check the
power supply connector, to avoid damage to the connector loose or aging
brings to the spindle and the drive.
(5) If the downtime to
use again, you must tranches from low speed to high speed spindle run-in
steps according to the spindle load running, in order to use in the
run-through.
(6) during the loading and unloading cutter knife, must tool chuck nut clean.
3. Use Caution
(1) must match the drive
spindle chosen correctly according to the electric spindle nameplate
good debugging power, voltage and frequency.
(2) Set the frequency
converter should be set command channel, and then set the display
channel, and finally set the parameters. When setting parameters, be
sure that the reference frequency, the frequency of the three highest
rated frequency and consistency.
(3) The spindle is
generally clockwise in the wrong direction, the drive can change
settings or swap any two rotating wire the inverter output UVW terminal
on.
(4) In general,
water-cooled spindle surface temperature and ambient temperature greater
than 20 degrees, the heat can be considered a spindle; when air-cooled
spindle surface temperature greater than ambient temperature of 30
degrees, can be identified as the main heat seriously, immediately shut
down cooling, a check
4. Maintenance Caution :
(1) Spindle found
abnormal sound, should immediately stop checking. If you can not be
resolved, should be sent to the manufacturer or repair to professionals.
(2) the operation of an
abnormal burning smell, immediately stop checking. If you can not be
resolved, should be sent to the manufacturer or repair to professionals.
(3) If the spindle does
not run the boot, do not start over, you should carefully check the
following related matters: first check the drive parameters to determine
the input and output voltage, the spindle parameter settings are
correct. Second, check the power cord and wiring connector is plugged in
and determine whether the contact connector problem.
(4) Since the electric
spindle is a high speed, high rigidity precision components and must
therefore be sent back to me by professionals or for repair.
