Scheduled Maintenance of Band Saws and What is Involved
The reason you should always schedule maintenance for your bandsaws is that it will save you both time and stress in the long run.
Then there is the important fact that you will have to replace the blade less often – in other words, it’s going to save you money in the long run too. All three of these are good reasons to start jotting down times for maintenance in your work diary today.
Then there is the fact that it’s safer for you. The fifth reason for regular maintenance checks of your bandsaw is a big one in terms of your reputation – quite simply, it makes your cutting much better.
How to carry out preventive maintenance on your bandsaw
Make sure the blade tension is appropriate for what you’ll be cutting
Inspect hydraulics system
Check the guide alignment is in accordance with the manufacturer’s instructions
Inspect the chip removal system i.e. does the conveyor system work properly in removing all chips?
Monitor saw fluids to allow a free fluid flow through all nozzles
Inspect vices for wear (stationary and movable). Adjust, repair, or replace
Always align the vice to blade before cutting.
Look at the band speed, monitoring the maximum and minimum speeds.
Six monthly checks
Monitor the band wheel bearings. That means looking for any unusual wheel movement. If you find any, then replace.
Inspect the band guides
Check the drives and take a look at all the bearings
Does the drive wheel have excessive play?
Check the transmission oil level and replace any defective bearings or seals
Check for proper alignment, tension, and wear of the pulleys. You can either adjust or replace them, if necessary.
Inspect belts for wear, cracks, stretching and again replace if needed.
When changing the blade
Check the band wheels are running smoothly
Ensure the blade tension is the same as that recommended in the manufacturer’s guide
Before removing the blade, check the blade tracking. Is the spacing between the back edge of the blade and the wheel flange measuring around one-eighth of an inch?
Preventive maintenance may take a little time but who wants to cut with dull, breakable blades? And, in the end really, it’s all about the safety of the operator.
