Electric Spindle Practice :
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.
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
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.
Kindly Note :
1, Motorized spindle motors are matched with inverters, choosing inverters should be according to the current, voltage, and frequency of motorized spindle motors.
l Setting the inverter must firstly set up the basal frequency, its basal frequency is based on the highest frequency of motorized spindle motor, if not setting the basal frequency (the factory setting is 50Hz),the motorized spindle motor would burn out once start running;
l the highest frequency, break frequency and the corresponding voltage also should be set according to the curve on the operating instruction; setting the current of the inverters is also based on the rated current of motorized spindle motor;
l the overcurrent is 120% of rated current; overload tripping is 100%, time is 5s;
l carrier frequency is set by the power of spindle motor,8kHz for less than 10KW motorized spindle motor, 5kHz is for more than 10KW spindle motor;
l the acceleration time and deceleration time are 10s and 20s respectively, if starting current exceed the rated current and need protection, it should extend the acceleration time.
l I/O lack-phase protection also should be set above the function of protecting inverters and motorized spindle motors.
l Connecting the inverter and the three-phase power of spindle motor, solder the inverter three-phase power cord on the plug 1(U1),2(V1),3(W1), plug 4 is ground wire. Then the inverter is connected with the external power supply and start work, then to check whether the rotation direction of spindle motor is consistent with its indication direction, if inconsistent, immediately shut down and change two wire on the three-phase power supply of connecting inverter and motorized spindle motor. The motorized spindle motor is prohibited running in the wrong rotation direction.
l Power lines should be taken waterproof and shielding measures. The connection between motorized spindle motor and inverter should not exceed 25m.When the power cord of the water-cooled spindle motor connects the terminal block, it must be bent into U shape and fixed on the bottom of the terminal block and then connect, so that can protect the condensed water of the power cord into the terminal block.
l Another, use shielding power lines to prevent its interference to inverter .
