Moulder Spindles Broken shafts seized bearings welded tooling all can be prevented Prevention money in your pocket or more precisely money you get to keep in your pocket.
Typically if a bearing is failing you will start to feel a drag or a rough motion It may not free wheel like it used to You might also notice an obvious decline in the cut and finish quality These are symptoms of an expensive repair in the making Now is the time to get the spindle off the machine and in for repair If you are proactive you can schedule for some downtime.
Very often we see bearings destroyed and the result carries over to the shaft or the bearing housing causing catastrophic damage to the assembly These usually come in with the spindle housing bluishblack in color Now that spindle got noticeably hot before it came to a halt Someone was not paying attention as this had to be making an incredible noise before it seized Had it been sent for repair earlier it may only have needed a bearing replacement and a balance Remember that money in your pocket idea from earlier.
Im not going to spend any time on tooling balance other than saying its one of the most crucial factors in long spindle life Follow the manufacturers guidelines for the particular tooling you are using and make sure loose knives are all within 110th of a gram of each other.
Make sure the spacers and locknuts all are in excellent condition and the mating surfaces are free of burrs and nicks The objective is that they all push squarely on the tool body so everything is spinning perfectly and not running out of round and out of balance.
On hydro lock spindles we see many failures that are mostly related to poor operation and maintenance Always use the safety collar on your hydro tooling Its there for a reason It prevents the tool from being welded to the arbor shaft when the hydro pressure drops during operation We see more of this than you can imagine come through the door Most of the time we can save it but not always Either way its expensive.
Outboard bearings are the next in line for most failures On most machines the assembly is designed to float in the mounting plate so an axial spindle adjustment does not put any unnecessary preload side load on the bearing itself For some unknown reason some maintenance personnel or operators feel these should be rock solid and tighten them down in the housing so they cant move If the hydro sleeve is pressurized when the operator makes an axial adjustment it wont take long for that bearing to fail Again a preventable expense.
If you see this on the upper spindles have a qualified professional check the alignment of the complete spindleoutboard bearing assembly If you have multiple machines that are alike make sure every OBB plate is in its original position on the correct machine and never swap them around.
