Rebuilt Spindle Maintenance
Caring for your New Rebuilt Spindle
Smooth production relies on your machine’s spindle performance. Down machine tool spindles and repairs can be avoided through proper maintenance.
Here are seven simple maintenance tips to help keep your operations running smoothly.
1. Lubrication is key to a spindle’s performance and longevity.
Therefore, it’s important to keep your lubricating fluids clean and at safe operating levels. It’s also important to adhere to the machine tool OEM’s recommended lubrication schedule. If you have an air/oil spindle, be sure to service the air-intake filters on a regular basis.
2. Check spindle runout every 6 months and/or after any crash via a ground and calibrated spindle test bar.
Also, monitor your spindle’s spring force with a draw bar pull force test. Pull force is what secures tool holders in the spindle and a sizable drop in force could lead to vibration and runout, which can damage both your spindle and part.
3. Keep a constant watch on spindle vibration levels.
If your machine has built-in vibration sensing technology, don’t ignore any of the triggered alarms. Worn spindle bearings are usually the cause of increased vibration, so be sure to replace them when necessary.
4. Maintain spindle-bearing lubrication.
While closed-unit spindles are typically factory lubricated for life, large spindle headstocks, such as those on big turning machines, need to have their bearings lubricated with oil baths. As such, it’s important to maintain the oil levels of these baths.
5. If you have a high-speed spindle with a cooling system, always make sure the chiller unit is running properly.
A rise in chiller system output temperature usually indicates a spindle problem. If this occurs, a Mazak certified technician can thoroughly check the system.
6. Always re-install any machine covers that have been removed due to routine maintenance or any other reason.
These covers protect the spindle area, keeping contaminants from infiltrating the spindle, spindle motor and other components.
7. When your spindle requires a repair or rebuild, it’s best to have the machine tool OEM perform the services
When your spindle requires a repair or rebuild, it’s best to have the machine tool OEM perform the services to ensure the use of factory-certified parts and that all repairs reflect the equipment’s original specifications.
