tool-clamping accuracy and eventually scrap the rotor, but also abrade the
thread on nuts and rotor which will eventually levigate the rotor thread
and make the nut unlocked, loose and useless.
8、In order to ensure the necessary line speed for the small tool
cutting, the characteristic of high speed on the spindle is fully taken into
account when the spindle is designed. The rigid structure of the spindle
motor is limited. Overloading the spindle during cutting, inappropriate
processing parameters, and higher capacity on the spindle than its
designed ability will all shorten the spindle lifetime.
9、Due to the high speed rotation, there must be some gap between
spindle rotor and the material below. In operation, the cutting fluid should
be avoided splashing on the nut and rotor as much as possible. At
high-speed rotation, the cutting fluid retained on the rotor will go up to
the bearings along the rotor rotation, which will destroy the lubrication
conditions inside the bearing. It will greatly shorten the bearing lifetime.
10、To stop the spindle, please cut off the power supply first, then
turn off the cooling water when the spindle completely stops running. In
case of long-time deactivation, blow the cooling water out of the spindle
waterway with the compressed air.
11、The spindle bearing lifetime will become longer by using the
tools with precise dynamic balancing.
12、After the spindle is deactivated or stored for six months, it can
be used only when the grease is replaced, otherwise, its lifetime will be
affected.
13、The grinding wheel in the grinding spindle should be watched
out to make sure that the working line speed does not exceed the safety
line speed. Otherwise, accidents may occur.
