Warning prior to spindle liner insertion or removal be sure the lathe
is in emergency stop or power to lathe is off. Never remove or install a
spindle liner to a spindle that can be powered on during this process.
Warning do not operate lathe if using an extended spindle liner and
the extended cover is off of the spindle. Doing so could cause personal
injury and machine damage.
Caution be sure to use the proper fasteners for the spindle liner
retaining ring and if equipped spindle liner extension housing.
For the most support of the long pusher the lathe spindle normally requires a spindle liner. This
liner reduces the inner diameter of the spindle to the diameter of the pusher. The liner diameter
should be approximately 2mm larger than the pusher.
When installing a spindle liner for the first time the liner end may need to be cut. This is a normal
practice for the liner to be longer for the various chucking packages that are available. A longer
liner is better to have than a too short of one. The end of the liner should be approximately
13mm from the rear of the chuck jaws or collet. Any further and this could cause a load or
remnant ejection issue
Normally a spindle liner will be part of the options ordered from Edge Technologies. Additional
spindle liners may be order from Edge technologies.
