Maintenance
⑴、
Warranty period of bearings is 2500 hrs; for the other parts of the
spindle, it’s one year. However, maintenance has to be chargeable If users
ignore “air sealed”, which leads to the fluid or cutting chips entering the
bearing and then damaging the bearing / spindle.
⑵、
For new spindle or spindle with renewed bearings, to prolong its
lifetime, gradually speed it up from low rpm to high rpm. About an-hour
running for raising every 10000 rpm, till the maximum speed. It avoids
shortening the bearing lifetime if the spindle directly runs at high speed.
⑶、
To stop the spindle, please cut off the power supply first, then
turn off the cooling water only 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.
⑷ 、
The spindle bearing lifetime will become longer by using the
tools with precise dynamic balancing.
⑸、
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.
