Routine maintenance of electric spindle of mill-turn CNC lathe

In the MACK40-300 electric spindle CNC lathe, the electric spindle is usually used in the way of frequency conversion speed control motor, which is the spindle motor and push motor of high-quality CNC lathe assembly. The motor motor rotor immediately assembles the tool, eliminating the transmission system stage of the belt disk and gearbox in the middle, and its function is to promote the rotation of the tool (sand wheel piece) or product workpiece to complete the fast and efficient precision machining. Spindle machining centers must be maintained, especially the spindle is very critical, but also vulnerable components, must be maintained!

Daily maintenance work is mainly clean up, which seems trivial, but to increase the service life of the fast spindle plays a greater effect! Spindle motor is a daily is damaged components, to increase its service life must be based on maintenance to bring a better office environment! Spindle motor daily maintenance should start from the following levels!

(1) to create the concept of cherish the new CNC lathe, if this habit is developed, fast spindle key maintenance work is guaranteed!

(2) operators in the daily operation after the completion of the spindle motor should be applied to vacuum clean up the motor rotor end and motor terminal row on the waste chips, to avoid the waste chips in the motor rotor end and terminal row on the deposition, in order to prevent the waste chips into the rolling bearings, accelerate the damage of high-speed bearings; to prevent the waste chips into the terminal row, resulting in motor short-circuit failure damage.

(3) Every time on the card and remove and replace the tool, three-axis CNC lathe operators must be the pressure cap chuck twisted open, not to apply immediately inserted the tool to change the way the tool!

(4) The operator should develop a habitual, after removing the tool to remove the collet and spindle clean and tidy.

(5) The same is also a habit, that is, the operator must be on the knife to the tool, collet and spindle clean and tidy! This key point to ensure that the spindle motor life can be greatly increased!

(6) daily after the start of the operator must check the motor cooling water running status, to check the submersible pump is not normal work, to check the cooling circulating water is not contaminated by dirt, microbial strains of environmental pollution, to check the pipeline is not normal, must ensure that the cooling circulating water circulating system is normal! It is prohibited to open the spindle motor without cooling circulating water utilization in the spindle motor! The spindle motor can only be in good operating condition under regular cooling conditions. If there is a dead end in the mains water pipe that prevents the flow of water or if there is dirt blocking the pipe, the spindle motor will not work properly and will directly affect the actual results of the production process.
