Kavo Spindle Replacement Program
CutGuru is pleased to offer the following spindle replacement program for Kavo spindles used on Kongsberg cutting tables (and some Zund PN and G3 series tables).
A replacement spindle will be supplied by CutGuru, typically by overnight or 2 day shipment (when stock is available – please call to confirm availability at 414-939- 3270).
The cost of this spindle is $8000. The customer will return the damaged spindle to MCT w/in 1 week of receipt of the replacement. Upon timely return, MCT will apply a $2000 credit against the $8000 replacement spindle price. For returns taking longer than 1 week, the credit will be reduced by $100/day over 7 days from delivery of replacement spindle.
The replacement spindle will have a 6 month or 1000 use hour warranty (whichever comes first). Warranty will be granted upon inspection of a returned spindle. Warranty will not be honored for spindles whose wear exhibits excessive use beyond the spindle’s capabilities.
If help is needed to diagnose the extent of possible spindle problems, please call CutGuru at 414-939-3270 and press 1 for CutGuru or email email@example.com
Spindle failure can usually be diagnosed in two ways:
If the spindle is running or seems to be running, does it actually engage or is it not really spinning at set RPM. It could be running but not really turning or turning very in a very “lazy” fashion so it wouldn’t remove any material that it would come in contact with.
With the machine not in running mode, you can try to turn the tip of the spindle with your fingers (best with no bit inserted) to see if it turns freely or binds or makes any noises when turning. If the spindle makes any noises while running or manual turning, please shut down immediately as this is a prime indicator that something is wrong and there is virtually a 100% chance that continued running will only damage the spindle further.
Care and Feeding of a Spindle
Always warm up a spindle before running any jobs.
Do not push a spindle at high RPM through very rigid materials (e.g. acrylic, metal, dense wood, etc.). You may think you’ll get the job done a little faster but you will most likely be severely shortening the life of the spindle.
For thick material where you will run multiple spindle passes through the material, do not set the depth of the cut any more than 1.5 times the diameter of the spindle. It stresses the spindle (bearings) and is difficult to remove the waste chips by going too deep. If left over waste after multi-passes, a final “clean out” pass that does not remove any additional material but vacuum out debris can be a big help for final clean up.
