1. electric spindle practices :
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.
